NATURAL SCIENCES OF PHILADELPHIA. M 



antennae, (the lower a little broader than the upper) converging behind I 

 they pass through the eye (plainly to be seen in fresh specimen) and become 

 a single black stripe behind the eye which reaches to the posterior incision of 

 the pronotum, decreasing in width as it passes along the lateral angle, Pro- 

 notum ash-colored on the dorsum, posterior lobe palest, with minute brown 

 tubercles scattered over it, a dark brown spot on each side. Elytra brown, 

 darkest next the base, semi-transparent at the apex. Wings transparent yellow 

 next the base; apical half dusky ; this dark marginal band is broad in front 

 but tapering toward the inner angle but does not reach it ; reaches along the 

 front submargin nearly to the base; is somewhat darkest at the inner and 

 outer borders, reaching to the apex. Posterior femur reddish with two ob- 

 lique darker bands on the outer face, and three black bands inside. 



Dimensions. Length 1 in. ; to tip of elytra 1-26 in. ; to the end of pronotum 

 (from the front of the head) -31 in. ; femur -54 in. ; tibia -41 in. 



Hub. New Mexico. 



CE. Carliniaxa, nor. sp. 



Female. This species at first sight has much the appearance of CE. Carolina, 

 but an examination of the head or thorax, or spreading the wings will soon 

 undeceive the observer. Although smaller than that species it is more robust, 

 compared with its length. Head carved much the same as CE. eorallipes. 

 Occiput short, sub-convex, not ascending ; vertex very broad, slightly de- 

 flexed : the broad shallow central foveola divided by a median carina 

 into two elongate pentagonal spaces, the median carina and margin next 

 the eye being the longest sides; the lateral shallow foveola; triangular: at 

 the top of the frontal ridge is a lunate depression; frontal ridge somewhat 

 broad, obtusely margined, expanded at the ocellus, vertical, reaching the 

 cross suture ; lateral carinas distinct, reaching the corners of the face. An- 

 tenna? filiform, sub-planate. Pronotum sub-cylindrical in front, fiat on the 

 lateral lobe, expanded posterior^, not constricted; median carina a raised 

 line, cut by the cross incisions 1 and 3 ; posterior incision before the middle; 

 lateral carina? obliterated in front, distinct on the front of the posterior lobe: 

 posterior lobe densely punctate. Elytra and wings extend slightly beyond 

 the abdomen. Posterior femora short, not reaching the extremity of the ab- 

 domen ; inflated. 



Color (siccus). Ash-colored. Vertex and posterior lobe of the pronotum 

 tinged with reddish-brown. Elytra opaque and somewhat brownish at 

 the base, semi-transparent at the apex ; dotted with pale brown. Wings 

 when fully expanded present a very broad fuscus band across the base 

 parallel with the body, the outer border reaching beyond the middle ; a 1 

 triangular space at the apex transparent, with dark and white veins. Posterior 

 femora spotted with black inside ; tibia 5 yellow. 



Male. The male differs only in size, and in having the elytra crossed by 

 irregular brownish bands, somewhat as in CE. sequalis. 



Dimensions. Female. Length 1-38 in.; to tip of elytra 1-58 in. ; to tip of 

 the pronotum (measuring from the vertex) -45 in.; femur -64 in. Male. 

 Length 1-16 in. ; to tip of elytra L3b - in. ; to tip of pronotum -42 in. : femur 

 58 inch. 



Hah. Eastern Colorado. 



Named in honor of Col. Carlin, for the assistance rendered the expedition 

 by him. 



CE. NEGLECTA, IIOV. Sp. 



Female. Much like (E. corallipes, about the size of the male of that species, 

 for which it has doubtless often been taken. In its carvings, as well 

 it comes very near (E. Mexicana, Sauss. Vertex very broad, transverse, fo\ eo- 

 late; the large central foveola divided, by the recurving margins, into t 

 contiguous foveolae, these margins, seen from the front, form a W, with a line
