p. 330. in Rhynchophorini add :

A specimen of the well-known Rhynchophorus palmarum was collected by Mr. Hardy, in Southern California, west of San Diego, and kindly sent to me by Dr. David Sharp. As groves of palm trees are known at several places on the eastern slope of the Sierra in that region, it is not surprising that they should be depredated on by this species, which is widely diffused through the Antilles and tropical America.

Quid? Rhynchophorus noxius Gyll. Sch iv, 821. Perhaps an imported specimen of R. palmarum.

p. 331. Add the three following new species of Sphenophorus; the first belongs to Horn's group IV; the others to V; Proc. Am. Phil. Soc. xiii, 412.

Sphenophorus velutinus, n. sp.

Elongate, brownish black, entirely opaque and velvety in lustre. Beak shorter than the prothorax, curved, somewhat compressed, smooth; antennæ inserted immediately in front of the eyes. Prothorax more than one-half longer than wide, oval, strongly tubulate in front; the elevations are very vague and ill defined, the impressions are marked with shallow punctures; sides more densely and more deeply punctured; dorsal line narrow, slightly elevated, extending nearly to the base and apical constriction. Elytra not longer than the prothorax, narrowed behind from near the base; striæ very fine, marked with a few distant small punctures; two outer striæ with more numerous larger punctures; interspaces flat, obsoletely punctulate. Pygidium with a few large deep punctures, beneath sparsely punctured. Front and middle tarsi with the third joint broadly dilated, spongy each side beneath; third joint of hind tarsi slightly dilated, not wider than long. Length 11 mm.; .43 inch.

One specimen, Florida. Very different from all others in our fauna.
Sphenophorus variolosus, n. sp.

Of the same general form as S. arizonensis, black, somewhat shining; beak shorter than the prothorax, slightly curved, strongly punctured at base, nearly smooth at tip, which is moderately compressed. Antennæ inserted immediately in front of the eyes; head finely and sparsely punctured with a large frontal fovea prolonged anteriorly in a channel which extends as far as the beginning of the narrow part of the beak. Prothorax oblong, longer than wide, sides strongly rounded in front, and tubulate at the apex; impressions and elevations very vague, indicated by the presence of larger punctures in the places where the impressions should be, and of finer punctures on the elevations; there is a group of large punctures just behind the tubular constriction, and behind these punctures there is a smooth dorsal line extending nearly to the base. Elytra with fine deeply impressed striæ, along which are placed at irregular intervals very large shallow pits, through which the striæ run, producing a very curious appearance; interspaces finely sparsely punctulate, not elevated; the punctures of the outer striæ are smaller and deeper; those of the next

are quadrate and confluent. Pygidium coarsely punctured; beneath shining, sparsely punctured; more coarsely on the 5th ventral, which is impressed near the tip; flanks of prothorax and middle of abdomen nearly smooth. Third joint of tarsi scarsely broader than second, glabrous beneath, fringed only at the sides. Length 9.7 mm.; .38 inch.

Colorado, one specimen, Mr. B. D. Smith. The presence of the postapical group of large punctures on the prothorax affiliates this species to C. placidus, which however it does not otherwise resemble.

Sphenophorus oblitus, n. sp.

Of the same general form as S. placidus, black, covered with a dirt-colored crust. Beak two-thirds the length of the prothorax, stout, slightly curved, more strongly compressed at tip; punctured at base, smooth at tip; frontal groove deeply excavated, extending to the base of the narrow part of the beak. Antennæ inserted just in front of the eyes. Prothorax more than one-half wider than long, sides parallel for two-thirds the length, then gradually and obliquely narrowed to the tip, which is less strongly tubulate than usual; surface covered with large, shallow punctures, with the depressions very feebly indicated: the punctures just behind the constriction are a little denser at the middle, representing thereby the small impression which is distinct in S placidus, and nearly obsolete in S. variolosus; there is no smooth dorsal line. Elytra with fine striæ, very feebly punctured; interspaces with single rows of very fine punctures, alternately a little wider and more elevated. Pygidium sparsely and deeply punctured. Beneath coarsely punctured on the flanks of the prothorax; punctures smaller and distant at the middle of the abdomen; fifth ventral sparsely and very deeply cribrate. Thighs sparsely and rather feebly punctured; front tibiæ distinctly sinuate on the inner side, but not angulate; tarsi with the third joint not dilated, glabrous beneath, fringed only at the sides. Length 9.6 mm.; .38 inch.

Texas; one specimen, Mr. G. W. Belfrage. This is also to be placed near placidus, to which it has but little resemblance. It also shows a tendency towards the compressirostris form, in which, however, the beak is not curved, and the front tibiæ are strongly angulated on the inner side.

Sphenophorus cariosus Oliv., Ent. v, 83, 91, pl. 28, 415; Horn, Pr. Am. Phil. Soc. 1873, 420, cum. synon.

Dr. Horn has suggested to me that this species and S. callosus Oliv., should be united. After careful examination of the specimens in my collection, I think this view is correct. Those who are inclined to adopt it will place callosus as the synonym, since it is represented by old and abraded specimens.

Sphenophorus sculptilis Uhler, Proc. Acad. Nat. Sc. Phil. 1855, 416; Horn, l. c. 424.

With this species should be united as a synonym S. Zea Walsh, Practical Entomologist, ii, 117; Riley, Missouri Ent. Report, iii (1871), 59, fig. 22. PROC. AMER. PHILOS. soc. xv. 96. 3B

p. 331 add the following new genus:

TRICHISCHIUS n. g.

This genus is founded upon one species, which agrees with Sphenophorus, except in the following characters :

The inner side of the front and middle coxæ and the middle of the metasternum and the first and second ventral segments are clothed with long hair; the thighs beneath, and the tibiæ on the inner side are fringed with long hair; the genital segment of the projects (as in Rhynchophorus) and is fringed with hair at the tip. The third joint of all the tarsi is slender, not at all dilated or emarginate, glabrous beneath, fringed at the sides, and quite as long as the second joint, which is equal to the first.

The prothorax is uniformly punctured, without impressions, but with a narrow, smooth dorsal line, and the elytral striæ are deep and crenate; the interspaces are even, and scarcely punctulate.

1. T. crenatus, n. sp.

Black, subopaque. Beak scarcely more than half the length of the prothorax, slender, slightly curvéd, finely punctured, with a very fine longitudinal impressed line near the base, which terminates in a small, frontal fovea. Prothorax nearly one-half wider than long, narrowed in front of the middle, and rounded on the sides, tubularly constricted near the tip; base nearly truncate with the edge acute, and sparsely fringed with yellow hairs; disc rather densely but not coarsely punctured, more coarsely towards the base, each side of the medial line, where it is feebly impressed; dorsal line narrow, very distinct, slightly elevated near the base. Elytra at base a little wider than the prothorax, basal angles slightly projecting forwards; striæ deep, crenate, interspaces nearly flat, scarcely perceptibly punctulate; humeri reddish; pygidium with the hind part strongly, rather densely punctured; apex (7) declivous, smooth, concave; genital plate prominent, smooth. Beneath shining, strongly but not densely punctured; punctures larger on the metasternum; side pieces narrow. parallel; prosternum very narrow between the coxæ. Length 8.8 mm.; .35 inch..

Colorado; one specimen, Mr. B. D. Smith.

p. 365, add as a synonym to

Tomicus pini; T. pallipes Sturm, Cat. 1826, p. 76; T. dentatus Sturm, ibid. pl. iv, f. 30. Say's name has priority by one year.

p. 357, add as a synonym to

Xyloterus bivitatus; Apate rufitarsis Kirby, Fauna Bor. Am. iv, 193. p. 337, after Gononotus add

HIMATIUM Woll.

I would refer to this genus, which is fully described by Mr. Wollaston in Trans. Ent. Soc., London, 1868, 461, a small slender reddish-brown opaque Cossonide, thinly clothed with coarse hair.

It has all the characters given in the description, except that the hairs are not long, and the antennæ are not very pilose and the surface not shining. The more important ones may be recapitulated as follows:

Body narrow, linear, rather flat, sparsely pubescent. Beak parallel, cylindrical, separated from the front by a distinct impression; eyes rather large, transverse, coarsely granulated, situated on the sides and under surface of the head, not visible from above. Antennæ inserted about the middle of the beak, short and stout, scape attaining the eyes; funicle first joint large, 2-7 very short, closely connected, club small, oval, shining, sparsely hairy, annulated only at the tip. Metasternum rather long; front coxæ widely separated, the others still more distant; tibiæ with the terminal hook very large; tarsi rather short, third joint but little wider, somewhat bilobed.

The genus has thus far occurred only in Malabar, and Pholidonotus, which immediately follows it, is found in Borneo. It appears, therefore, to be a third instance of that remarkable distribution which I have previously mentioned in the Heteromerous genera Othnius and Ischalia.

1. H. errans n. sp.

Very elongate, reddish-brown, nearly opaque, thinly clothed with coarse yellowish hair. Beak a little shorter than the prothorax, rugosely punctured, transversely impressed at the base. Head finely punctured. Prothorax more than one-half longer than wide; widest near the base, sides suddenly rounded behind the widest part, but gradually obliquely narrowed in front and nearly straight; slightly constricted near the tip; disc rather flat, densely and coarsely punctured, without impressions or dorsal line. Elytra not wider than the widest part of the prothorax, truncate at base, scutellum not visible, sides parallel, rounded at tip; striæ deep and broad, punctures large, quadrate, interspaces very narrow. Body beneath very coarsely punctured; punctures of ventral segments not smaller. Length 2 mm.; .08 inch.

District of Columbia; collected by Mr. Ulke. I owe a specimen of this interesting species to the kindness of Dr. Horn.

APPENDIX II.

UNRECOGNIZED SPECIES.

1. Rhynchites virdiæneus Randall, Bost. Journ. Nat Hist., ii, 23.
