E, callosa, Lee. New Species, p. 158. 



In sculpture resembles E. ferruginea, and differs in this respect only in 

 having on each side of the median line a small smooth callus. The 

 pubescence is, however, co^-ser and fulvous. Length .40-. 50 inch : 

 10-12 mm. 



Occurs from Dakota to Texas. 



The pubescence is very tine and very apt to be lost, in which case the 

 surface color alone appears and the species becomes totally black. 



B. 



E. caviceps, nov. sp. 



Black, moderately shining, sparsely clothed with fine whitish pubes- 

 cence. Head black, fine, punctulate, vertex and occiput broadly concave : 

 eyes very narrow, scarcely one-third as wide as long ; antenna? scarcely 

 more slender to tip and nearly half as long as the body. Thorax broadly 

 oval, sides arcuate and gradually narrowed to apex, surface moderately 

 convex, feebly shining, and minutely punctulate. Elytra black, finely 

 scabrous, sparsely clothed with cinereous pubescence, sutural margin in 

 front of middle thickened for a short distance and somewhat elevated. 



Body beneath black, sparsely pubescent with white, and rather densely 

 punctulate. Length .30-. 40 inch ; 7.5-10 mm. 



Two specimens are before me, both females, which differ from all the 

 species in our fauna by the broadly excavated vertex and occiput. The 

 elytra at basal third along the suture are elevated into a slight hump, 

 apparently caused by the thickening and elevation of the sutural margin 

 at that place. The pubescence as in E. pruinosa is fine and apt to be lost 

 when the species appears black with a very slight lustre. 



Two specimens from Arizona, kindly loaned by Mr. Ulke. 



C. 



E. pedalis, Lee. New Species, p. 157. 



Black, sparsely cinerecvpubescent. Head sparsely punctured, median 

 line finely impressed. Thorax longer than wide, sides behind parallel, 

 at apical third moderately arcuate, median line rather deeply impressed, 

 surface moderately shining, coarsely but not densely punctured. Elytra 

 finely punctato-scabrous and sparsely pubescent. Body beneath black, 

 moderately shining, sparsely punctulate and pubescent. Legs rufous, 

 anterior tibia?, knees and all the tarsi somewhat darker. Length .36 inch; 

 9 mm. 



Three males are before me having a single spur to the front tibia, 

 slightly arcuate and directed inwards. 



Lower California. 



E. parclalis, Lee. New Species, p. 157. 



Head black, shining, with large smooth spaces, between which the sur- 

 face is finely and sparsely punctulate and sparsely pubescent. Thorax 

 as broad as long, sub-campanulate, punctured similarly with the head.
