198 THE CANADIAN ENTOMOLOGIST. 



ti'ohs by European authors. In appearance it is Lithosii-form, with rather 

 narrow primaries and broad secondaries ; the vestiture is close, smooth ; 

 vein 5 of secondaries is said to be wanting ; fore-tibia unarmed ; the spurs 

 of middle and hind tibia normal. I do not remember the venation of 

 primaries, and made no note as to the origin of vein lo.

Genus Utetheisa Hiibner. 



1816 — Hiibn., Verzeichniss, 168. 



A well marked genus containing very handsome and extremely 

 variable species, since it has been determined that all our forms are but 

 varieties of one species. The head is distinct, free, eyes rather large, not 

 prominent, ocelli distinct. The palpi are slender, ascending, reaching the 

 middle of front, the terminal joint rather long, closely scaled. Antenn?e 

 moderately long, slender, simple in the % , in the ^ the joints marked 

 with single lateral bristles. Legs closely scaled, quite considerably longer 

 posteriorly, all the spurs complete and moderate in length. Body closely 

 scaled. Primaries with vein 10 out of the subcostal, a short cross vein 

 connecting \< with the stalk bearing 7, 8 and 9, and thus forming an 

 accessory cell ; 6 is from the end of the sub-costal : 4 and 5 are close 

 together out of the end of the median  3 somewhat remote from 4, but 

 rauch nearer than to 6. Secondaries with 3, 4 and 5 very close together 

 from the end of the median ; 6 and 7 together from the end of the sub- 

 costal ; 8 as usual about one-third from base out of the subcostal. Both 

 Crocota and Emydia lack vein 5 of secondaries, which is a decided 

 Lithosiid tendency ; Utetheisa has 5 well marked, and has a distinct 

 accessory cell, the relation to Callimorpha being obvious in the entire 

 scheme of venation. 



As the species are attractive as well as variable, the literature is 

 voluminous, and yet I have given none of the " popular " or economic 

 references.
