460 ENTOMOLOGICAL NEWS. [Dec., 'l6 



mcnt as to the species being edenata, also as to the varieties, 

 pointing out, however, that one of the varieties appeared to be 

 a rediscovery of one of Packard's species, H. (Cidaria) gJ.au- 

 cata. This variety I have called olivata n. var. 



Packard says of glaucata "pale glaucus green," olirata is 

 dark. In glaucata the extra discal space is quite wide on the 

 inner margin and the black bar on this margin is absent: in 



olivata the extra discal space is very narrow and the black bar 

 is evident on the inner margin. The fore wings are elongated 



in my variety, while in glaucata, as figured in Packard, the 

 fore wings are more rounded, as in the* European rubcrata, of 

 which it may be simply a green variety. In view of these 

 differences I feel that the new name is justified. 



Hydriomena edenata, n. var. olivata. 



Olivata is separable from the typical edenata by the following differ- 

 ences ; basal area concolorous, narrowly linear first line, which is also 

 different in its course, running in long even sigmoidal curves from 

 costa to the middle of the inner margin, there being no sign of an 

 angle on the subcostal vein : bar on inner margin lacking or but faintly 

 indicated ; no contrasting colors but rather a dull mottled appearance 

 brought about by the rather indistinct breaking up of the bands, none 

 of which is distinctly traceable. The whole surface of the primaries 

 is suffused with a distinct olive shade. The hind wings show a very 

 definite brown extra discal line and a faint rather diffused line in the 

 middle of the space beyond. In one specimen the mesial space is a 

 little lighter and nearly immaculate. 



Types, three males, San Diego, California, collected by the 

 author, one of which is in the Swett collection. 



Hydriomena edenata, n. var. pallidata. 



The second group of specimens, under the name of pallidata, is 

 separable on the course of the first line which is straight from costa 

 to inner margin ; the absence of the black bar and the fact thai the 

 "usual wide irregular bluish band" of edenata has become, with the 

 corresponding bluish band in the subterminal space, a light watery 

 gray and is the most prominent marking on the primaries. All the 

 lines are broken up, and more or less linear. The whole aspect is as 

 though the specimens were very much faded. 



The type is in the author's collection, paratypcs in the 

 Swett and Marloff collections.
