8 THE CANADIAN ENTOMOLOGIST. 



to me, but the larva resembles that of the European Z. subitrigella, as 

 figured in Nat. Hist. Tin , xvi. The head is pale sordid brownish, upper 

 portion of next segment a very little darker, with a crimson spot on each 

 side of the dusky portion and another just above the feet. The next 

 segment has the crimson spots larger and more diffuse, and on top of it 

 begins a wide crimson line which extends along the dorsum of all the 

 segments to the anal ; the remaining segments, except the last two, have 

 each three crimson spots on each side of the median crimson line, instead 

 of two, as in those immediately following the head ; each of the last two 

 segments has a transverse crimson line. 



Z. obscurusella Cham. 



The form of the palpi, the tufts along the dorsal margin of the fore 

 wings, and the neuration of the wings in this species resemble those of 

 Chauliodus Lint., and it perhaps belongs as properly in that genus as in 

 Lavcrna — if, indeed, any well marked distinction exists between the genera. 



Z. ? ignolrilisella Cham. 



As stated in the Can. Ent., v. 7, p. 51, the imperfect description of 

 this species was unintentionallv published, and the mistake was discovered 

 too late to correct it. Since then, having received other material, I have 

 been enabled to give a more correct account of the species. The orna- 

 mentation resembles closely that of Z. ? Coloradella Cham., and they 

 may prove to be varieties of the same species. The form of the head 

 seems to me to differ, however, the head and face in the Texan specimens 

 being wider than in those from Colorado in proportion to their length, and 

 there is, so far as I am able to compare them with the material before 

 me, a decided difference in ornamentation, though the resemblance is 

 strong. 



The wings are not tufted and the second palpal joint is but little 

 enlarged towards its apex. Head, antennae and basal joint of palpi sil- 

 very white, stalk of antenna? yellowish fuscous: Thorax and fore wings 

 silvery white, with an ochreous costal spot about the basal fourth of the 

 wing length, extended to the fold, sometimes interrupted so as to form two 

 spots, one on the costa and one on the fold, and the costal margin to the 

 base more or less stained with fuscous ; just behind the middle the wing 

 is crossed by an ochreous band, and the wing at its tip and along the 

 base of the dorsal cilia? is dusted and suffused with ochreous. Cilia? 

 white, hind wings and legs whitish. Al. ex. nearly ]/ z inch.
