much thickened at the apex in the males; alulets rather small, but with the scales unequal in size; wings with the third and fourth longi. tudinal veins parallel or slightly convergent at their extremities, anal vein prolonged to the margin; legs always black or grey. 1. PLUVIALIS, Linn. 2. ALBICINCTA, Fall. 3. PRATINCOLA, Panz. 4. RADICUM, Linn. vulgaris, R. Desv. brassica, Wdm. 5. SULCIVENTRIS, Zett. 6. OCTOGUTTATA, Zett. A. PLUVIALIS, Linn. This common pretty spotted fly varies a good deal, the spots often coalescing so as to alter the design on the thorax and abdomen. Two of the varieties thus produced have been exalted by Rondani into distinct species, but they possess no real specific distinctions. A. ALBICINCTA, Fall. This little species bears a good deal of resemblance to the last, but, besides being very much smaller, differs in having the thorax black, with two white spots on the hinder part in front of the scutellum. The abdomen is marked as in A. pluvialis, being white with a dentated black band at the base of each segment. Not common. A. PRATINCOLA, Pz. This species has the abdomen marked in a very similar manner to those of the two preceding ones, but the thorax is peculiarly figured, being of a whitish-grey colour, with a single black elongated rhomboidal mark in the centre of the posterior part. It is about the same size as A. albicincta (about 3 mm., 1 lin.), and is also rare. A. RADICUM, Linn. This excessively common little fly, which, as its name imparts, feeds in the larva state upon the roots of plants, especially on those of the cabbage tribe, is often confounded with other species. It may be recognised by its projec.ing epistome; by the unequal sized scales; by the thorax being black, and marked in the male by two short, grey, narrow stripes (rather than by three wide black ones, as is usually stated); by the rather short, wide, somewhat pointed abdomen, with a longitudinal dorsal black mark, crossed by three transverse straight black lines, extending of an even width to the margins; and by the third and fourth longitudinal veins of the wings being slightly convergent at their extremities. A. SULCIVENTRIS, Zett. This species bears a good deal of resemblance to A. radicum, but is less; has the antennæ much shorter; the arista more pubescent; the thorax without any distinct stripes on the dorsum, only having an irregular white line on each side; and the abdomen less pointed, and thicker at the apex as well as differently marked; it being of a dull grey colour, with three transverse sulci on the dorsum, and a rather indistinct longitudinal black stripe, which appears in certain lights to be dilated into triangular spots, opposite the sulci or depressions. Common in pastures. A. OCTOGUTTATA, Zett. This little species (which only measures about 2 mm.) also has considerable resemblance to A. radicum, being marked in a very similar way on the abdomen, by a longitudinal and three transverse stripes, which divide the surface into eight light grey square spots; the thorax, which is black, has also two short white stripes on its anterior parts: it differs, however, from A. radicum in having both the face and epistome less prominent, the third and fourth longitudinal wing veins quite parallel at their extremities, the abdomen narrower, sub-cylindrical, more hairy, and furnished with two projecting lamellæ beneath the apex in the male, which is but little thickened; the alulets are also smaller in proportion than in A. radicum, but still have the scales slightly uneven in size. I have only seen one male specimen of this rare little fly, which I captured near Bradford in July, 1875. (To be continued). A LIST OF THE BUTTERFLIES CAPTURED IN BARRACKPORE PARK DURING THE MONTHS OF SEPTEMBER, 1880, TO AUGUST, 1881. Barrackpore is situated on the right bank of the river Hoogly, 16 miles above Calcutta. The park comprises a strip of land on the river-bank some two miles long by about 1200 yards broad. Insect life, in the way of butterflies, commences to be active about March, and increases till May, when there is a slight lull till the rains commence about the 15th or 20th June. Insects are then very plentiful till the end of August, when another lull occurs till about the breaking up of the rains-the end of September, or first week in Octoberwhen the collecting season finishes up with a fine burst of life, lasting to about the 20th October; after which insects gradually disappear, few butterflies, &c., being seen after the end of that month. The flowers most frequented by butterflies in the park are: Duranta Plumieri, Quisqualis indica, Poinciana pulcherrima, Mussanda macrophylla, and a tree with a small white hanging blossom (name not known), but the first-named is by far the most attractive. EUPLEINE. Limnas Chrysippus, Linn., Salatura Genutia, Cram., Tirumala Limniacæ, Linn., very common. March to October. Heavy, lazy flight. Parantica Aglea, Cram., rare. Communicated (with description of a new species) by Frederic Moore. Crastia Core, Cram., very common. March to October. Heavy, lazy flight. Frequents the shade of Banian trees, &c. Very fond of settling on damp ground. Frequently taken in coitu. [Isamia Rothneyi, Moore (n. sp.), male. Upper-side olive-brown; basal area darkest fore-wing with a sub-marginal row of small whitish spots, and a marginal row of smaller spots, both rows decreasing in size towards the costa; sericeous streak short and broad: hind-wing with a pale flesh-coloured discoidal patch; a submarginal row of oval, and a marginal row of smaller, whitish spots. Expanse, 3 inches. In colour and pattern of markings, this interesting new species resembles the very common C. Core, for which insect Mr. Rothney mistook it. One specimen only occurs in this collection, and it is the only example known to me. Its nearest ally is a Ceylon species (I. Sinhala).-F. Moore.] SATYRINE. Lethe Europa, Fabr., one specimen only captured. Melanitis Ismene, Cram., common, but difficult to catch. Found in shade, either under bamboo or under mangoe topes. When disturbed is fond of settling in cactus hedges. Calysisme Samba, Moore, Blasius, Fabr., Drusia, Cram., Perseus, Fabr., indistans, Moore, common. Fond of shade. Settle mostly in long grass. Elymnias undularis, Drury, male common; female rare. foliage, close to the trunk. Settles in dense Charaxes Fabius, Fabr. NYMPHALINE. Symphædra Nais (Thyelia, Fabr.). Two specimens only captured.

Drona, Horsf., rare; during the rains. Catopsilia Catilla, Cram., not uncommon during the rains. July and August. Crocale, Cram., very common, especially during the rains; a lover of sunshine and flowers. The variety (Endeer) occurring at the same time. Pyranthe, Linn., very common during the rains. There is a faded (?) or dull dirty-coloured form that appears with this insect, so constant in its uniform appearance, that it almost suggests a variety or species (?). This is generally found during the rains, and also early in the year. It is not very common. Gnoma, Fabr., Ilea, Fabr., not common. Ixias latifasciata, Butler, Marianne, Cram., rare. Appear during the rains. Most difficult to capture: have a powerful and very dodging flight. Huphina Evagete, Cram., Zeuxippe, Cram., Hira, Moore, common in the rains. Fond of flowers, especially Duranta Plumieri. Catophaga Paulina, Cram.: two specimens only taken during the rains; Darada, Feld., one specimen only. Belenois Mesentina, Cram., one specimen only.

Orpheides Erithonius, Cram., extremely common, from end of March to end of October. A dark, yellow variety is also found at the same time and places, but is comparatively rare. This latter has a much stronger mode of flight, and is much more difficult to capture. The difference of action is almost sufficient to suggest a difference of species. Laertias Pammon, Linn., common. March to October. The dimorphic females (Polytes and Romulus) much less frequently met with. Menelaides aristolochia, Fabr. (Diphilus, Esp.), very common: October; Hector, Linn., common: March to October. Chilasa dissimilis, Linn.; Casyapa, Moore, common during the rains. HESPERIIDE.

Udaspes Folus, Cram., rare. Odd specimens from May to August; in long Hesperia Galba, Fabr., common, May to September. April, 1882. NATURAL HISTORY OF HELIODES ARBUTI. BY WILLIAM BUCKLER. It is with extreme gratification that I now find myself giving the history, from the egg, of this little sun-loving species, which I owe to the most kind and persevering help I had the pleasure to receive from Mr. H. T. Stainton in 1880, and again in 1881. In the former year on the 23rd of May, I received a cluster of about eight eggs, resulting from a moribund female after being a short time in a killing bottle of poison, but long enough, as it proved, to have destroyed their vitality. On 26th of the same month, I was elated on receiving alive five captured examples of the moths; as two of them were females I imprisoned them and the most lively male together, in a pot containing |
