THE CANADIAN ENTOMOLOGIST. 255 



reaching to posterior line, having a pale dusty ochre annulus edged out- 

 wardly with black, brown interiorly. Orbicular moderate, round, a little 

 oblique with an interior brown annulet. Reniform upright lunate, pale 

 dusty ochre, with an interior brown curved shade divided by a whitish 

 hair-line on the cross vein. Posterior line curved, running inwardly below 

 median vein, but not abruptly. The subterminal space is shaded with 

 dusty ochre beyond the line. Subterminal line preceded by distinct long 

 interspaceal black dashes. Terminal space narrow, shaded with black. 

 A black terminal line ; fringes pale at base, interlined. Hind wings dusty 

 ochrey fuscous with distinct wide black borders ; veins soiled with fuscous; 

 beneath paler with traces of a mesial line and the black border repeated. 

 On fore wings the black border is less vivid and there are blackish shad- 

 ings on the cell and traces of an extra mesial line. Thorax and head 

 colored like primaries ; collar with a fine line in front, and double lines 

 above. Fore tibiae with a terminal spine and a shorter one opposite ; eyes 

 naked. Length of primary 15 mil. Hal\ Colorado, Mr. Neumoegen ; 

 several examples. 



This species approaches augustus in ornamentation ; the band on 

 secondaries is broader and their color is darker, being ochrey fuscous, 

 while in augustus they are whitish. The long black interspaceal dashes 

 before the subterminal line are wanting in the Texan species, in which the 

 claviform is vague and the orbicular spherical. 



Since my first discovery of this interesting genus in North America it 

 has been enriched by many species. In the European Catalogues four 

 species are enumerated from the Altai and Ural regions. The following 

 is a list of our species with localities :
