Type defoliaria Clerck. 

 Ili/bernia Latr.. Fani. Nat. 477, 182.5, type defoliaria Clerck. 



Palpi very short, almost rudimentary ; tongue very .*hort, aluio.st 

 obsolete; front scaled, broad; antenme of" S with long fascicle of 

 hairs from four .slight protuberances on each segment ; thorax hair 

 scaled, somewhat tufted anteriorly, hairy below; abdomen scaled; 

 hind tibiie not swollen, without hair {)enci!, in both sexes with two 

 pairs of spurs; fore wings without fovea below in S , 12 veins; hind 

 wings 5 obsolete, and 7 widely .'^e})arate, 8 sej)arate from cell ; 

 wings broad, rounded, even ; 9 with wings obsolete. 



Under Alxoph'da I have sj)oken of the application of the generic 

 term Krantils. It cannot be a])plied to the s])ecies ordinarily grouped 

 under Aiiisopteryx Steph. as they belong to Hiibner's genus Also- 

 jj/ii/tt. The only proper application is to regard defoliaria as the 

 type of ErannU, as this was beyond (piestion the idea of Hiibner. 

 The species ordinarily grouped together in that genus I do not l)e- 

 lieve to be properly congeneric. Apart from other things there are 

 great differences in the antennie of the males, the majority having 

 the antennte bipectinate and so decidedly different from the antennae 

 of E. defolidfia. Hybenda Latr. if not regarded as a synonym of 

 Erannis, must stand for the species with bipectinate antennae in the 

 % . But that group had already been called Agrilopl.-< by Hubncr. 

 Our species are all of the defoliaria group. 



Species. — E. defoliaria var. vancoiiverensis Hulst. 

 E. filiaria Ilarr. 

 E. coloradida Hulst, n. sp. 



E. defoliaria var. vancouveren-sis n. var. I give this varietal name 

 to a form which seems to be common at Victoria, Vancouver Island, 

 Canada. It is very uniform, and is much more shar|)lv marked 

 than the typical defoliariti, and the shadings of the % , and the 

 general color of the 9 , ai-e much darker. The typical foi-m of de- 

 foliaria is not found as yet in ourfauiuil limits so far as I am aware. 



K. coloradata n. sp. — ExikuuIs 4() nun. P;il|ii fuscous l)rovvn, black at 

 end ; front fuscou-s brown ; thorax and abdomen smoky ocher, the segments of 

 abdomen darker anteriorly and dorsally ; fore wings fuscous ocher, overlaid with 

 dull brown ; basal field dark, limited by a black line, which begins at costa one- 

 quarter out, runs sharply outward, making sharji dentations at subcostal and base 

 of vein 5, then forms a sinus inwardly with another sharp dentation near vein la ;
