accident soon after its birth, and all trace of it obliterated in its subse- 

 quent moltings. 



Pupa. 1.90 inch long, .50 inch brond. Dark brown. Head-case 

 rounded, quite corrugated, projecting by one-half the length of the first 

 segment beyond it. Exserted tongue-case. .25 in. long in its outward 

 curve, its base anteriorly, opposite to the anterior margin of the first 

 segment, not bulbous at its tip and not resting on the breast,— with an 

 impressed line and confluent transverse wrinkles ; the buried portion 

 reaching to the tips of the wing-cases. The anterior leg-cases, promi- 

 nent over the femur, impressed at the joint between it and the tibia, — 

 both pairs of leg-cases transversely wrinkled. Antennaj-cases in the $ 

 not extending to the tips of the anterior leg-cases. Wing-cases trans- 

 versely wrinkled. First segment depressed anteriorly, corrugated, with a 

 medial line, its stigma quite open. Second segment slightly i-ounded 

 dorsally. corrugated, with a medial line. Third segment with a sub- 

 dorsal fusiform depression, and not compressed at the base of the wing- 

 cases. Abdominal segments with conspicuous transverse wrinkles, and 

 numerous punctulations, — those on the anterior wrinkles with elevated 

 margins. Terminal segment in $ . very full and obtuse. Stigmata, 

 fusiform. Spine short, broad, constricted at the base, excavated infe- 

 riorly. with a bifid tip. I $ . 



I have had the Imago of this species to emerge, after two winters 

 passed in the pupa state, although in the same box with others, which 

 made their appearance at the usual time. It attains a large size, occa- 

 sionally measuring 4.70 in. in expanse of wings. Both the moth and 

 its larva appear to be rare. 



Philampelus satellitia Linn 

 Larva. Length when extended, 4 inches — when at rest, with its 

 head and thoracic segments retracted within the fourth segment, 3 

 inches, and .59 in. broad. Head reddish-brown, small and rounded. 

 Body, of a transparent reddish-brown, lighter dorsally, with small ocel- 

 lated spots on the annulations. Fifth to tenth segments inclusive, each 

 with an oval cream-colored spot, in which is the stigma. In some in- 

 dividuals, only the superior half of the anterior spot on the fifth seg- 

 ment is given, — in some, its position is merely indicated by a dot, and 

 in others, it is wholly wanting.
