110 THE CANADIAN ENTOMOLOGIST. 



COLEOPHORA. 



C. gigantetta Cham. 



A typographical error in the original description makes it read " these 

 are in the apical part of the wing " for " three are in," etc. The species 

 was described from a single specimen from Canada, and was placed in the 

 section " having the palpi simple." Since then I have bred it from cases 

 found in May attached to Maple trees ( Acer saccharinum ), in Kentucky. 

 The specimen in Mr. Saunders' collection had probably been a little 

 injured in setting, as in the bred specimens I find there is a minute tuft 

 at the apex of the second joint of the palpi, and there is also an ochreous 

 streak from the base along the dorsal margin of the fore wings. 



Among the European species figured in the Nat. Hist. Tin. ,C. virgaurez 

 most nearly resembles this species, which, however, is larger than virgauree 

 and has no brown dusting on the wings. Virgaitne, likewise, has the costa 

 narrowly white to the middle, whilst in gigantella the extreme costa is of 

 the same pale brownish ochreous with the streaks on the wing. The 

 streaks on the fore wings are in other respects alike in the two species. 

 The hind wings, abdomen and anal tuft are gray (in virgaurcc the tuft is 

 yellowish ochreous). The cilia; of the fore wings are a little paler and 

 more grayish than the streaks on the wings, and the outer surface of the 

 palpi is brownish ochreous. The larval case is of the same form in this 

 species as in virgaura, except that it is a little more slender, and it is of a 

 sordid brownish-yellow color. The imago comes out in the latter half 

 of June. 



C. shalerieila Cham, resembles gigantella closely, but is a little larger, 

 having an al. ex. of i v .j inch, while that of gigantella is five lines ; and in 

 shalerieila the antenna; are not annulate with brown. 



Both of these species approach C. cratipennella Clem. Dr. Clemens 

 gives no measurements, and I have not seen his species ; but from his 

 account of it, it would seem to differ from gigantella and shalerieila by the 

 unusual width of the streak which extends along the wing between the 

 costal and subcostal veins, and by "the stripe along the subcostal vein 

 which sub-divides into two branches terminating on the costa," and in the 

 number and course of the streaks in the apical part of the wing ; the color 

 of the basal portion of the costa is not stated by Dr. Clemens. 



I have no specimen of shalerieila for comparison now, and it may prove 

 to be identical with gigantella.
