464 GEOLOGICAL SUEYEY OF THE TEREITOEIES. 



baud across tbe basal two-tliiids, 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. Y^n- 

 ter and ])ectus dull yellowish-white. Antennse pale at base ; apical por- 

 tion dusky. 



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

 ora, .64 inch ; X'^sterior tibiae, .bo 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, and quite dif- 

 lerent from any other one belonging to the United States y.hich I have 

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

 Ungiana^ but wdiile 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 /ooA-, (this word conveys my 

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

 ern si^ecies, and may be found in the Indian Territory or Texas.

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. euccrata^ Harr., but invariably larger. Head large, 

 front of the occiput elevated; vwtex broad, nuich deflexed; central 

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

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

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

 ocellus. Eyes slightly oblong, sub-globose, prominent. Antenna) slen- 

 der, passing the thorax. The pronotum 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 angleil, apical angle 

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

 the body. 



Coloi\ (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 jniddle of the pro- 

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

 the sides of the head and pronotum, the upper one end)racing the lower 

 I)ortion of the eye. The elytra have the upper half and apical third 

 sprinkled with small fuscous spots; on the lower half there are tw^o 

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

 ulate space. AVings i)ale transparent yellow at the base, (color when 

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

 baud crosses just beyond the middle, curving abruptly ui)on the ])oste- 

 rior margin to the anal angle; tip more or less clouded, rest of the ai)ical 

 portion pellucid, nervules i)ale yellow^, (tij) of the male, fuscous.) Pos- 

 terior femora, with two or three dim oblique bands exteriorl}^, inside 

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



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

 inch; posterior tibiLe, .5 inch. ^, length, .75 inch. 



Found near the Platte Pivers, in Colorado and Wyoming.
