AMERICAN LEPIDOPTERA. 3G8 



66. ERANNIS Hiib. 

 Verz. 320, 1818. 



Type dffoUaria Clerck. 

 Hybernia Latr., Fam. Nat. 477, 1825, type defoliaria Clerck. 



Palpi very short, almost rudimentary ; tongue very short, almost 

 obsolete; front scaled, broad; anteunse of % with long fascicle of 

 hairs from four slight protuberances on each segment; thorax hair 

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

 hind tibijie not swollen, without hair pencil, in both sexes with two 

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

 wings 5 obsolete, 6 and 7 widely separate, 8 separate from cell ; 

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



Under Almphila I have spoken of the application of the generic 

 term Erannis. It cannot be applied to the species ordinarily grouped 

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

 phila. The only proper application is to regard defoliaria as the 

 type of Erannis, as this was beyond question the idea of Hiibner. 

 The species ordinarily grouped together in that genus I do not be- 

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

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

 the antennae bipectinate and so decidedly different from the antennae 

 of E. defoliaria. Hybernia 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 Agrilopis by Hubner. 

 Our species are all of the defoliaria group. 



Species. — E. defoliaria var. vancouverensis Hulst. 

 £r tiliaria Harr. 

 E. coloradata, Hulst, n. sp. 



E. defoliaria var, vancouverensis 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 sharj)ly marked 

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

 general color of the 9 , are much darker. The typical form of de- 

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



K. coloradata n. sp. — Expands 46 miu. Palpi fuscous brown, black at 

 end; front fuscous 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 sharj) dentations at subcostal and base 

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