80 BEITTSH BUTTERFLIES. 



hybernates nearly fullgrown. Aigner-Abafi notes (111ns. Zeits. fur 

 Ent., iii., p. 328) that he "found the larvae of E. argiades, which other- 

 wise only lives in the Buda-Pest district on Lotus corniculatus or species 

 of Medicago and Trifolium, in the year 1897, in the pods of Colutea 

 arborescens, whilst searching for the larvae of Lycaena tolas, the pupa 

 producing in due course a normal imago. At the same time were 

 also found, in the same pods, larvae of Cupido minimus, until then only 

 known on Coronilla varia and Melilotus" Harris states that in America 

 the larva of the comyntas form lives solitarily in the heads of Lespedeza ; 

 Scudder confirms this, and adds that the larvae prefer the heads even 

 when the latter are mature, and have little succulence. Edwards 

 reared (Can. Ent., viii., pp. 202 et seq.) larvae on Desmodium and 

 clover (Trifolium), but only one matured on the former and ten on the 

 latter. On the Desmodium , the eggs hatched July 12th (laid on the 

 9th); on the 15th, one larva passed its first moult ; on the 18th, the 

 second moult ; on the 21st, the third moult ; on or about the 26th, 

 the fourth moult, pupating on July 31st (the imago emerging on 

 August 9th). The larva reared was green in all its stages, and the 

 pupa green, but the larvae on clover were red or reddish throughout, 

 and the pupae were dirty-white. The larvae at first were such minute 

 objects, as to be almost invisible, particularly on Desmodium, as both 

 larva and plant were nearly of the same shade of green ; on the clover 

 they escaped sight among the flowerets; on the latter, the tender leaves 

 were also eaten by the very young larvae, a single larva eating out two 

 or three furrows the width of its body, and side by side ; as they be- 

 came larger they seemed to feed on the calyces of the flowerets exclu- 

 sively, curving themselves into the surface of the- clover-head, or 

 burrowing into it. On Desmodium, as there were no flowers in bloom, 

 only the tender leaves and immature flower-buds were eaten. 

 Scudder says (Butts. New England, ii., p. 908) that he was informed 

 by Eiley that, in California, the larva of amyntula lives within 

 the pod of Astragalus leucopsis, frequently with a Noctuid larva, and a 

 Curculionid larva, feeding normally upon the young and tender seeds, 

 but also showing quite a carnivorous propensity, and eating its 

 associates when not too active or too large. It leaves the pod to 

 pupate. 



Ontogeny of larva. — First instar: Pale brownish-red, differing in 

 intensity, with a dark dorsal vessel, and a rather thick pubescence, 

 three very faint, whitish, longitudinal lines, are visible with a lens on 

 either side. Third instar': About 2^'"- long, paler, greenish in colour 

 with more or less reddish ; the greenish red-brown dorsal vessel, is 

 edged with whitish, and expands greatly on the anterior segments, but 

 is not visible on the prothorax ; on either side of the body run two 

 wavy, faint, whitish, longitudinal lines, below which the ground colour 

 is reddish, but varying in intensity, as far as the lowest (third) whitish, 

 longitudinal line; one larva showed no red tint. Fourth instar: Paler 

 in colour. Fifth instar (fullgrown larva): Head black ; labrum and 

 antennae white ; 5"'-6'" long ; pale green, with a dark green dorsal 

 line wider at the extremities (dorsal vessel) ; flanges with a reddish 



° Zeller gives no account of the second instar; his lirst description is up to the 

 first moult, his second after the second moult, i.e., third instar.
