veins and sometimes reduced to a series of dots. Discal spot not very distinct. Fringe 

 checkered white and gray. Secondaries with a single submedian, irregular, brownish 

 line, most distinct toward inner margin and marked by a brown spot on some of tlic 

 veins. Terminal line and fringe as in fore wings. Discal spot brown, distinct. 

 Beneath whitish on inner two thirds with a scattering of pale brownish scales. Ex- 

 tradiscal line repeated, followed by a narrow strip of ground color, the remainder of 

 outer area pale brown with the blotches of above reproduced in it. Secondaries like 

 primaries save that it is the submedian line that is reproduced. Discal spots on all 

 wings prominent. 



The above describes the female type more particularly ; a co-type 

 is much the same in markings but the cross lines are almost absent and 

 are indicated by the brown spots by which the lines are marked. 



Types. — Two females in the author's collection. 



Habitat. — Yavapai Co., Arizona, May 23 and 29. 



12. Euemera angularia, new species. 



Expanse, 30 mm. In wing form differs from the described species of the genus 

 in being obtusely angled on primaries at vein M 3 and acutely angled and extended on 

 secondaries at the same vein. Head, thorax and abdomen pale creamy- yellow. 

 Wings concolorous, the primaries shaded with ochreous outwardly and costal ly and 

 both wings speckled with numerous brown transverse strigre, especially heavy on 

 outer half of secondaries. Fore wings crossed by a single rather broad brown line 

 which is obscurely divided by a faint and somewhat broken line of gray scales ; it 

 begins on the costa one third in from apex, runs curvedly outward a short distance 

 and forming an acute angle extends to inner margin in a series of slight irregular, 

 inward scallops ending one third in from the anal angle. Discal spot small, brown, 

 linear. Fringe brown. Hind wings also crossed completely by a single line corres- 

 ponding to that on the fore wings. It is a pale brown, extends across the wing a 

 little outward of the middle and is irregular throughout its course, being as a whole 

 straight except for the curve from costa. A little below this line a still paler -hade 

 line departs from it and thence diverging runs to the inner margin. Discal spot 

 absent. Fringes as in primaries. Beneath, paler, the brown strigrc consequently 

 showing up more prominently. Striga? entirely absent from inner areas. The lines 

 of the upper side are quite strongly reflected, that on the fore wings broadening at 

 the costa. Discal spot present on fore wings ; absent on hind wings. 



Type. — One fine male in the Academy of Natural Sciences, 

 Philadelphia. 



Habitat. — Carr Canyon, Huachuca Mts., Cochise Co., Arizona, 

 in August (Dr. Skinner). 



Differs decidedly from its congeners by the angulated wings and 

 by the transverse line of primaries being bent inwardly near the costa 

 instead of at the center of the wing. 



13. Phengommatsa spoliata, new species. 



Expanse, 34-38 mm. Dead, thorax, abdomen and fore wings of male dark bull. 

 the head somewhat lighter than the rest ; hind wings much paler outwardly, shaded
