From a comparison of the egg, larval and pupal states, as well as (he 

 imaginal, that not only arc the two species distinct, lint thai there are really 

 two genera, and for vernata he proposes the name Paleacrita. While his 

 work shows great care and thoroughness, J am unable to agree with Mr. 

 Wiley's opinion that the differences he points out are of generic importance. 

 The imaginal characters are certainly not so; for in other genera we have as 

 greal differences between the different species. The European cbscularia 

 would have to form the type of a third genus, it Mr. Riley's views are 

 correct. We have seen that, as regards the larval characters, vernata in one 

 case has an extra pair of legs, and the two species are sometimes easily con- 

 founded in the larval state. The eggs of the two species are very distinct ; 

 but the form and structure of the eggs in the Phalcenids have not been exam- 

 ined enough yet for us to form a deeided opinion as to what are generic and 

 speeilie characters among them.

Male. — Six examples. Palpi shorter than in A. vernata; antennae sub- 

 pectinate, ciliated, the cilia; arising from much larger tubercles than in A. 

 autumnata, and only one pair to a joint. Fore wings a little more elongated 

 toward the apex, the outer edge being a little longer and more oblique than 

 in A. vernata. Instead of being pale ash-gray as in vernata, this species is of 

 a peculiar ochreous-brown tint, as in the European eescularia. There are two 

 broad whitish bands on the fore wings ; the basal is regularly curved outward, 

 and is situated nearer the middle of the wing than usual: it ends on the 

 costa in a dark spot. A faint, discal, linear streak. On the outer fourth of 

 the costa, a broad, distinct, oblique white spot connecting with a bread, dif- 

 fuse, zigzag, white line ending on the inner angle of the wing. A broken, 

 linear, black thread at the base of the fringe. Hind wings clear, with a pale, 

 indistinct, extradiscal line. Beneath is a pale costal spot connecting with the 

 extradiscal taint shade, which is common to both wings. 



Length of body, 0.40; lore wing. 0.G5 ; expanse of wings, 1.38 inches. 



Female. — Antenna' not hairy (laid backward along the side of the body
