THE CANADIAN ENTOMOLOGIST 57 



and paler and sub-translucent at the joints. Wings very large, hyaline. 

 Veins heavy, black. Areolet very small, radial area open, broad. The 

 base of the radial area covered with a dark semi-transparent cloud which 

 includes the 2nd transverse vein. The cubitus in this species, as in C. q. 

 bella, is heaviest towards the ist transverse. At their intefsection there is 

 a dark cloudy spot, and a still larger ashen cloud near the tip of the wing 

 This last does not touch the veins nor the margin of the wing. 



Abdomen very large, and viewed laterally, nearly circular in outline ; 

 I St segment a little longer than the four following taken together. These 

 last are sub- equal, and each of a deep yellowish brown on the posterior 

 half, but lighter anteriorly. All the light bands, together with the lateral 

 portion of all the segments, covered with minute microscopic hairs. 

 Sheath of the ovipositor small, with a brush of rather long hairs at the 

 apex. 



Length: Body .15, wing .20, antennae .13. This fine and truly 

 remarkable species was collected in the Mule Pass Mts. in Arizona, in 

 Nov., 1879, by Prof. E. T. Cox, to whom I am indebted for many 

 other interesting species. 



COENONYMPHA ELKO. 



BY W. H. EDWARDS, COALBURGH, W. VA. 



Male : Expands .95 to i inch. 



L^pper side pale ochre-yellow, immaculate ; fringes concolored. 



LTnder side of primaries nearly same ochre-yellow over basal area and 

 part of disk, limited without by a slightly sinuous and crenated edge of 

 deeper color, much as in the allied species ; outside this, slightly ochra- 

 ceous next inner angle, but yellow-buff over apical area. 



Secondaries have the basal area uniform gray-brown, the outline dis- 

 tinct and in strong contrast with the remainder of the wing, which is 

 yellow-buff. Very slightly dusted gray ; the outline is irregularly cren- 

 ated, with a deep sinus on upper sub-costal interspace and another on 

 lower disco-cellular interspace. 



Female : Expands i inch to 1.02. 



Upper side like the male. Bene;ath, the area just outside the crenated 

 edging on disk of primaries is yellow for a little distance, then tinted
