462 GEOLOGICAL SUEVEY OF THE TEEEITOEIES. 



cariuse distinct ; apex riglit-angled ; antennre slender, passing tlie pro- 

 notum ; eye, sub-globose, prominent. 



Color, (dried after immersion in alcohol.) Ash-gray, mottled with fus- 

 cons, which pervades nearly uniformly the head, thorax, and elytra ; 

 sometimes two yellowish stripes are more or less distinct on the disk of 

 the pronotum, one along the inner side of each lateral carina. Wings 

 X)ale transparent yellow next the base, (possibly -pale red when living;) 

 apical half dusky, the inner margin of this part darkest, forming a rather 

 narrow, irregular band, which curves but slightly on the posterior mar- 

 gin, not reaching the anal angle ; the apex clouded. The lower channel 

 and inside of the posterior femora black, with a pale ring near the apex; 

 antennae fuscoas, with yellow annulations. 



Dimensions. — Length, .85 inch ; elytra, .9 to .95 inch; posterior femora, 

 .46 inch ; i)osterior tibiae, .4 inch. 



Found in Colorado and Wyoming. 



I have specimens which are probably females of this species, but as I 

 am in doubt in regard to them I have not attempted to describe them 

 as such. 



CE. Wyomingiana, nov. sp. 



Very similar to (E. collaris, Scndd., but differs in size, in the carvings 

 of the vertex and in the distribution of the spots on the elytra. 



Central foveola of the vertex slightly elongate ; the sharp margins 

 not quite meeting in front, but continuous with the sides of tlie frontal 

 costa ; frontal costa narrow, rather deeply sulcate, expanding below, 

 reaching to the clypeus. Median carinse of the pronotum prominent, 

 sub-cristate, with a very narrow but deep notch or incision a little in 

 advance of the middle, the notch directed obliquely upward and back- 

 ward ; the top of the median carinse is slightly arcuate ; anterior margin 

 slightly angled, the posterior extremity terminating in an acute angle; 

 lateral carinas distinct. Antennas reach a little beyond the thorax. 



Color, (dried after immersion in alcohol.) — Dull clay-yellow, mottled 

 and spotted with brown and fuscous. Face and sides of the head and 

 pronotum minutely dotted with brown ; two short brown stripes on each 

 side of the pronotum reaching from the front to the third transverse 

 incision. Elytra pale ashen-yellow, semi-transparent at the apex, with 

 a broad stripe of fuscous dots and small spots along the middle field 

 from the base to the apex; an indistinct i^ale line along the dorsal 

 angle; the dorsal margin near the base is usually dotted with brown; 

 the lower margin has some faint dots along it. Wings transparent yel- 

 low at the base ; apical third transparent with dusky nerves ; a mod- 

 erately black band crosses between these two parts, its width about 

 equal to one-fourth the length of the wing, curving round the hind mar- 

 gin to the anal angle ; a short, blunt, fuscous ray extends along the front 

 margin about one-third the distance toward the base. Hind femora 

 clay-yellow, with two bands and the apex fuscous externally; internally 

 it is black ; hind tibiss reddish. 



Dimensions. — 9 , length, 1 to 1.05 inches ; elytra, 1 to 1.05 inches ; 

 posterior femora, .62 inch ; posterior tibiae, .54 inch. ^^ , length, .8 inch ; 

 elytra, .85 inch. 



Found only in Eastern Wyoming. 



This may be but a variety of 6E7. collaris, Scudd., and I have described 

 it as new with some hesitancy on this account. 



CE. Montana, nov. sp. 

 Female. — In form and size much like CE. corallines, but a very distinct
