24 PACKARD, NOTES ON THE 



gular, the outer margin full, rounded at the apex and also at 

 the internal angle. 



The legs have the first pair of femora and tibias densely 

 spreading pilose and stretched out in front of the body as insome 

 Notodontians. The hind pair of legs are large and long, with 

 stout tibiae armed with two unequal pairs of spines, of which the 

 terminal pair is the shorter. 



In coloration the species are black moths with large white and 

 yellow rounded patches upon both pairs of wings, and with deep 

 vermillion upon the pro-thorax. 



PUPA. The specimen described is from . the cast skin, con- 

 sequently broken, from Dr. Harris' Cabinet, kindly loaned me 

 by Mr. Scudder. Compared with that of Eudryas the body is 

 not at all contracted at the base of the abdomen, there being a 

 continuous curve from the pro-thorax to the tips of the abdomen, 

 while that of Eudryas is very sensibly contracted at this point. 

 The head is too much injured to describe. The pro- thorax 

 differs in being square behind, where in Eudryas it is a little 

 pointed. The meso-scutellum is not at all defined in outline, 

 nor is the whole meso-notum so much produced behind, being 

 more bluntly rounded, thus making the meta-thorax longer. 

 The wings are in form, relative size and position as related to 

 the abdominal rings, much as in Eudryas. The basal abdominal 

 rings are beneath, broader than in Eudryas, and the spiracles 

 are much more distinct. 



The abdomen tapers much the same in both genera, the chief 

 difference lying in the tenth ring and the genital parts. This 

 ring is much smaller and one-half shorter. Seen from above 

 the ring is larger ; the upper pair of tubercles are broad and 

 squarely docked, and the tergum is lengthened out even with 

 them, while the surface has longitudinal rugae. The lateral 

 tubercles are obsolete. Beneath is a distinct curved line, which 

 is the trace of the claws of the anal legs of the larva. This 

 mark is obsolescent in Eudryas. The larva previous to pupa- 

 ting constructs an earthen cocoon, like that of ^Egeria, ac- 

 cording to Harris. 



EUDRYAS Boisduval. 



Head rather large, eyes and ocelli large and full. Antennae 

 not thickened in the middle, with short lateral setas in the male 

 and pubescent beneath. Front prominent, densely pilose, though 

 the hairs hardly conceal the conical clypeal tubercle, which
