48 THE CANADIAN ENTOMOLOGIST. 



contrast in the two shades. The general effect is blurred and indistinct. 

 On the fore wings, while there are no marked differences in the transverse 

 lines, yet in Distincta they seem narrower, neater, and give a more trim, 

 clear-cut appearance to the wings. The two teeth in the middle of the 

 marginal white line are much more distinct in the old species, they being 

 scarcely discernible in some of the specimens of the new. The t. a. line 

 in Distincta proceeds directly to costa, while in the new species it turns 

 inward just below costa and joins it at an acute angle. In other respects 

 the maculation is practically the same. The examples on which the 

 above comparative description is based were taken at Glenwood Springs, 

 Colorado, in August, September, and October. Types in my collection, 

 and also in National Museum. 



Gloveria Arizonensis, Pack. Male. — Females of this species are 



quite common, coming freely to light. The male, however, has never 

 been described, and so far as I know the two before me are the only ones 

 ever taken. They differ so much from the females that I have made the 

 following description of them : Expanse, two and three-fourths inches, 

 thus being considerably smaller than the females, which average three 

 and one-half inches. Maculation brighter and more distinct than in 

 female ; the contrasting light and dark blackish gray shades bringing out 

 the transverse lines in strong relief Basal space light gray, central 

 portion obscured by a dark shade. Median space mostly dark, only the 

 costa and infra-cellular parts being somewhat lighter. T. p. line accom- 

 panied by an outer shade, slightly separated from it by a light gray band. 

 The remainder of the subterminal space is the lightest portion of the 

 wing and is thinly scaled and quite translucent. Terminal space even 

 dark gray, sharply defined by the prominent s. t. line and strongly 

 contrasting with the subterminal space. Discal dot w^hite, distinct. 

 Hind wings ochraceous, costal and outer margins obscured by dusky 

 shade. Veins of both wings dark gray. Fringe of hind wings fuscbus, of 

 fore wings concolorous. Head and abdomen ochraceous. Thorax dark 

 gray anteriorly, shading into ochraceous posteriorly. Antennae dark 

 brown. Beneath ; hind wings as above. Fore wings, cellular region and 

 along costa to apex, as well as terminal area, dark ; the rest of the wing 

 light semi-translucent. Types : two specimens from Glenwood Springs, 

 Colorado ; taken in July and August.
