262 AMERICAN LEPIDOPTERA. 



of origin or date ; but the labels are identical, and despite 

 the difference in appearance obviously belong together. The 

 resemblance is to mimalonis, but the species is much more 

 robust and the vestiture is much denser and heavier. 



The male antennae have small, lateral, conical processes 

 with tufts of short bristly hair at tip. 



Euxoa cervinea n. sp. 



Ground color pale ashen-gray with a vinous red tinge, more or less 

 powdery. Head and thorax concolorous ; collar with a vague carneous 

 median line, else no maculation. Primaries with the normal macula- 

 tion well defined though never conspicuous, traceable in most in- 

 stances and almost completely obsolete in occasional specimens. Basal 

 line geminate, powdery, blackish, rarely present. T. a. line geminate, 

 inner element rarely present, so that usually it appears simple; out- 

 wardly oblique, a little outcurved in the interspaces to vein 1, and 

 below that with a long outcurve. T. p. line single, crenulate, evenly 

 outcurved over cell, a very little incurved below, forming the most per- 

 sistent feature of the transverse maculation. S. t. line concolorous, 

 almost evenly parallel with outer margin, defined only by differences 

 in shading between terminal and s. t. spaces, and these shadings are 

 not alike in any two examples, the line varies equally in distinctness of 

 definition. A narrow, broken blackish terminal line. Claviform small, 

 concolorous, very incompletely defined by dusky scales. Orbicular 

 concolorous, round or oval, varying in size, incompletely defined, the 

 cell between it and reniform usually darker, reddish or smoky. Reni- 

 form large, extending well below median vein, interiorly dusky, a 

 little constricted, incompletely defined. A dusky median shade line 

 extends obliquely from costa between the ordinary spots ; invades the 

 lower part of reniform and then runs parallel with and rather close to 

 t. p. line to the inner margin. Secondaries dull smoky gray in both 

 sexes, with a more or less obvious discal lunule and a dusky sub- 

 marginal line. Beneath grayish-white, powdery, with a well-marked 

 extra-median line and discal spot on all wings. 



Expands, 1.25-1.35 inches = 31-34 mm.

Five males, one female, in good to fair condition. This 

 is a species which I had confused with the Californian ?rna, 

 and which is probably the species referred to under that 

 name in Mr. Dod's Calgary list. In specimens with the 

 transverse maculation lost and the space between the ordi- 

 nary spots reddish, the resemblance to rcna is striking ; but 

 with a better series at hand the resemblance tends to dissona
