THE CANADIAN ENTOMOLOGIST. 61 



tic America, as well as from Hudson's Straits, I have come to the conclusion 

 that it is impossible to distinguish more than one species. It is true that 

 the variations in size, colour and distinctness of the band on the hind wing 

 below are great , hilt not greater, or even so great, as that found in some other 

 species I have already dealt with," and so on; '• this opinion is conlirmed 

 by Mr. J. Edwards's examination of the clasps of some of the specimens 

 differing most remarkably in appearance, including the type of Subhya- 

 lina, in which, fortunately, a critical examination is possible without 

 dissection." I assert that the author here is totally wrong, and that he 

 has mixed up two, if not three species, and I deny that the example 

 in the Oberthur collection is the type of Subhylina, Curtis. Curtis 

 described a single male, no other example taken, which, he says, he 

 thought at first sight was an old and faded specimen of Hipparchiai?(75.y//, 

 just before described. But, on examination, "it proved to be in good con- 

 dition." He says it is black and the wings are semi-transparent, and the name 

 Subhyalitia implies that it is nearly transparent. Hyaline, in the diction- 

 ary, is given as glassy, transparent. Now, Crambis is a comparatively opaque 

 species, and no more hyaline than are the leathern wings of a bat. y£no, 

 Boisdjis somewhat translucent, aboutas much so a.s Sem idea, not transparent, 

 like C. Brucei, which is a sub-hyaline species. Neither of these has the 

 peculiar appearance which led Curtis to think it old and worn. Crambis 

 is dark brown, ^no is brown, varying from livid to yellow-brown. Bois- 

 duval, Icones, p. 195, describes the color as " un gris-brunatre-livide 

 mele de jaunatre." Assimilis, as I have said, is an unbanded form of 

 .■Eno, and was described by Mr. Butler in his Catalogue of Satyridse. I 

 sent two examples, one quite unbanded, the other partly, to Mr. Butler, 

 and he pronounced them his Assimilis " undoubtedly." It is found 

 wherever Ai.no flies, and copulates with ^tio. Subhyalina was taken in 

 1830, described in 1835. In course of sixty odd years the chances are 

 against the survival of any particular cabinet insect. It has a hundred 

 enemies, beside the possibility of accident. It is not an unknown thing 

 for the owner of a collection of insects, when a type is destroyed, to 

 attach the label to another example that seems near, or pretty near, the 

 original. He knows of the accident, and of the shifting of the label, and 

 would explain it if circumstances rendered it necessary. But he dies, and 

 his collections pass to another hand, and no one notices the discrepancy 

 between the description and the supposed type. It is the rule that when 

 description and type are found to be antagonistic, the latter must be ig-
