Polyommatus Comyntas Godart. 



Aug. 8, 1830. Found two larvae solitary, on the heads of Lc.spedcza 

 capitata. Body elliptical, convex above, flat beneath; segments distinct, 

 granulated minutely; color pale green; a dorsal, dark green line, two lateral 

 ones each side of it, midway between the dorsal lines and the sides, of a 

 paler, less conspicuous green; lateral margins reddish, forming a lateral 

 reddish line. First and last segments paler, reddish, the former hooding 

 and concealing the head in repose. Head very small, shining black, retrac- 

 tile. Feet sixteen, but very small, and with the under side of body uniform 

 pale green. The body is covered with short, erect, minute hairs. Length 

 forty-four hundredths of an inch. It carries a silken line when it moves. 



Aug. 13, A. M. Found that one had just become a pupa, lying on its flat- 

 tish belly, with a transverse band of little threads; it was also fastened by 

 the tail. The other had formed its band, but was not metamorphosed. 



Aug. 15, A. M. The second became a pupa. Body short, obtuse at both 

 ends; very pale green, covered with long, erect, white hairs, spotted mi- 

 nutely with blackish; a dorsal row of large, conspicuous, black spots, con- 

 tiguous towards the head, a lateral one each side, not extending quite to the 

 head. Wing thecte with about three, longitudinal, narrow bands of black- 

 ish, which, from the disposition of the wing cases, are oblique with respect 

 to the body, extending from the shoulders towards the back, or from below 

 upwards and backwards. The body is slightly contracted laterally before 

 the middle, broadest behind the middle, more obtuse before than behind, 

 and the thorax projects slightly above. It is fastened by the tail, and by 

 several transverse threads, which are across the body before the middle. 

 Length almost three tenths of an inch. 



Aug. 20, changed its colors. Aug. 22, A. M., became perfect insect. 



The second one changed its colors Aug. 24, becoming much darker and 

 almost black, except at the margins of the wing cases. Aug. 26, became 

 perfect insect; pupa state from nine to eleven days. 



Imago observed March 20, 1825, Aug. 22, 1830, June 1, 1833, July 15,
