ADSCITA STANCES. 395 



back yellow, slightly brownish dorsal tubercles ; lateral tubercles 

 pinkish, the lower ones brownish. (3) With the back pale yellowish, 

 the sides dusky, with very little tinge of pink. Five different forms of 

 the full-fed larva are figured (Larvae, etc., ii., pi. xviii., figs. 1-ld) by 

 Buckler. 



Comparison of larva of A. statices with that of A. g-eryon. — 

 So far, I can well separate the larvae of A. statices from those of A. 

 (jeryon by their greater size, their very much brighter colouring, and 

 by the form of the dorsal line, which is not so decidedly a double 

 dark line with a pale centre (Hellins). In structure Hellins failed to 

 find any difference. He further adds that larvae of A. (jeryon exhibit 

 less variation in colour than those of A. statices, and that they seem 

 more active than the larvae of the latter, unrolling themselves more 

 quickly, and walking off whilst under examination. 



Cocoon. — The larva of A. statices spins a thin, white, filmy, but 

 tough cocoon, which is attached to stems of plants close to the ground. 

 Chapman says that the cocoon is spun within a little loose outer silk, 

 white (or nearly so) in colour, that it is of a flattened ovoid shape, 

 with a flat, valvular opening, the edges closely drawn together at the 

 anterior end, and a small conical projection at the hinder end, into 

 which the cast larval skin is wedged ; the whole sufficiently flimsy to 

 allow the chrysalis within to be easily seen, but without detail. 



Pupa.- — Pale brown, rather transparent looking, and fairly uniform 

 in tint throughout, about 9 mm. in length, and 4 mm. in breadth ; 

 the depth from back to front is less, especially behind the wings, the 

 front being flattened, and more so the front of the free abdominal 

 segments ; it is broadest about the middle of the wings (2nd abdominal 

 segment). The head projects forward a little, with some trace of a 

 neck ; the maxillae and third pair of legs project conjointly beyond the 

 wings to nearly the extremity of the pupa ; the wings reach to the 

 5th abdominal segment. The wings and appendages are quite free 

 from the 4th abdominal segment, and apparently also from the first 

 three also, except a portion of the third ; these three segments are 

 closely covered by the appendages, and the first two do not appear to 

 move on each other in any ordinary circumstances, and the wings, 

 especially, fit very closely the margins of abdominal segments 1 and 2, 

 and both these segments, where covered, are of very delicate cutaneous 

 structure ; still there appears to be no actual soldering of the ap- 

 pendages to these segments. The antennae, which are of the same 

 length as the wings, meet in the middle line, and so cover all the tarsi 

 of the second pair of legs, and the last joint of the tarsi of the first 

 pair. Between the maxillae and first pair of legs is a portion of the 

 first femur (or trochanter?). The spiracles are on a distinctly raised 

 fluted margin or flange along the abdominal segments ; this flange is, 

 indeed, a large element in the broad flattened character of the pupa. 

 In this respect, however, the pupa is not so exaggerately flattened as 

 the pupa of the American representatives of this group. As distin- 

 guished from the pupae of most groups of Lepidoptera, this pupa has 

 the spiracle of the first abdominal segment just visible behind the 

 wings, whilst the second, usually exposed, is beneath the wings, but 

 visible through them, owing to their transparency. Dorsally, there is 

 a narrow head-piece, broadest against the antennae, nearly evanescent 

 in the middle line. There are no obvious markings or hairs on the
