464 GEOLOGICAL SUEVEY OF THE TEEEITOEIES. 



■band across the basal two-tliirds, with its outer border parallel to the 

 body. The posterior femora have two oblique brownish bands on the 

 external face ; within are two black bands ; apex black internally. Ven- 

 ter and pectus dull yellowish-white. Autennse pale at base j apical por- 

 tion dusky. 



Dimensions. — Length, 1.14 inches ; elytra, 1.25 inches ; posterior fem- 

 ora, .04 incli ] posterior tibise, .55 inch. 



Found among the collections submitted to me from the Agricultural 

 Department, marked Kansas, which, from the other specimens, I sup- 

 pose to be correct. The species is somewhat remarkable, ami quite dif- 

 ferent from any other one belonging to the United States which I have 

 seen. The dark wing would appear to bring it near Carolina and Car- 

 lingiana, but while it approaches the former in its slender form, it is 

 nevertheless very distinct. I have never met with it at any point in 

 the West, nor have I seen it in any other western collection. On this 

 account, added to that of its semi-tropical hole, (this vrord conveys my 

 idea better than a long sentence,) I am inclined to believe it is a south- 

 ern species, and may be found in the Indian Territory or Texas.

(Proc. Acad. Nat. Sci. Phil., 1870, 70; Hayden's Geol. Surv. Terr., 1870, 275.) 



As the description I gave of this species appears to have been from a 

 variety not common, I give again a description in full from a number of 

 specimens. 



Somewhat like (E. eucerata, Harr., but invariably larger. Head large, 

 front of the occii>ut elevated j vertex broad, much deflexed; central 

 foveola sub-quadrilateral, transverse in the female, but narrower in the 

 male, opening in front into the sulcus of the frontal costa; the frontal 

 costa of moderate width, sulcate throughout, exi3anding slightly at the 

 ocellus. Eyes slightly oblong, sub-globose, prominent. Antennae slen- 

 der, passing the thorax. The x)ronotum has the median carina distinct, 

 not prominent on the posterior lobe, slightly prominent on the anterior 

 lobes, notched twice, middle part very short, the posterior transverse 

 incision about the middle, front margin slightly angled, apical angle 

 a little more than a right angle. Elytra and Avings about as long as 

 the body. 



Color, (dried after immersion in alcohol.) — Clay-yellow, varied with 

 brown and fuscous. Lower portion of the face, the cheeks, and lower 

 margins of the sides of the pronotum pale yellow; two or three rows of 

 brown dots on the occiput; a broad stripe along the middle of the pro- 

 notum, brown. The male generally has two oblique brownish stripes on 

 the sides of the head and pronotum, the upper one embracing the lower 

 portion of the eye. The elytra have the upper half and apical third 

 sprinkled with small fuscous spots; on the lower half there are two 

 broad fuscous bands, behind each of which there is a pale yellow immac- 

 ulate space. Wings pale transparent yellow at the base, (color when 

 living, unknown, but presume it is yellow;) a moderately broad fuscous 

 band crosses just beyond the middle, curving abruptly upon the poste- 

 rior margin to the anal angle; tip more or less clouded, rest of the apical 

 portion i)eilucid, nervules pale yellow, (tip of the male, fuscous.) Pos- 

 terior femora, with two or three dim oblique bands exteriorly, inside 

 blackish next the base, a pale ring near the apex. 



Dimensions. — 9, length, 1 inch; elytra, 1 inch; xiosterior femora, .55 

 inch; posterior tibice, .5 inch. <J , length, .75 inch. 



Found near the Platte Eivers, in Colorado and Wyoming.
