tVoiu a coinparisoii of tlio eyfi;, larval ami pupal states, as well as the 

 iiuaiiinal, lliat not only arc the two s]>ccics distinct, hut liiat there are really 

 two irenera, and tor n'riiala he ])roi)oscs the name Palcacrila. AVliile his 

 work shows great care and thoroughness, I am i:nal)le to agree with IMr. 

 Riley's opinion that the diil'erences he points out are of generic importance. 

 The ima^Mual ehai-aeters are certainly not so; i()r in other genera we have as 

 great dillerences hctwecu the different species. The European ascuhuin 

 would have to llirm llu; type of a third genus, if Mr. Iiiley's views are 

 ct)rrect. We have seen that, as regards the larval characters, rcnuita in one 

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

 founded in the larval state. The I'ggs of the two species are very distinct; 

 but the ibrni and structure of the eggs in the Fhuheukh have not heen exam- 

 ined enough yet for ns to form a decided opinion as to what are generic and 

 specific characters amoiig them.

Male: — Six examples. Palpi shorter than in A. vcntafa ; anteniue sub- 

 ])eclinate, ciliated, the cilia- arising from much larger tubercles than in A. 

 aiifiunnatii, 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. vcrnuta. Instead of being pale ash-gray as in vcnuita, this species is ot 

 a peculiar ochreous-brown tint, as in the Jviropean (Vfirnlaria. Tliere are two 

 broad whitish bands on the fore wings; the l)as;d is regularly curved outward, 

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

 coslti in a dark s|)ot. A faint, discal, linear streak. On the outer iourth of 

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

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

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

 iiulistinct, extradiscal line. 15ene;itli is a ])alc costal spot connecting with the 

 extradiscal fiint shade, which is common to iiolh wings.
