Horn. I *"* Dec. lit, 



The club of the male antenna is very little longer than 

 that of the female, the anterior tibiae tridentate in both 

 sexes. 



This species is, next to inda, the most common in our 

 fauna. It occurs from the Middle States westward to 

 Kansas, and to Florida and Texas, extending even into 

 Mexico. 



The above description, rather detailed for one so common, 

 is given that the specific limits when compared with melan- 

 cholica may be made more evident. 



E. melancliolica Gory. 



Body beneath black, shining, usually with green or dark blue lustre, 

 upper surface equally shining, surface greenish-bias or nearly black. Clyp- 

 eus as in mpulbtctlis, head not hairy. Thorax formed as in that species, 

 the punctuation coarse, denser at the sides but not confluent, the surface 

 entirely devoid of hairs. Elytra also similar, the punctuation less deep and 

 more sparse, and at the sides very faintly or not at all strigose, surface de- 

 void of hairs, and with whitish lines similar to those of sepulcralis but less 

 sinuous. Body beneath as in sepulcralis. Length .48-.G0 inch; 12-15 mm. 



The antennal club of the male is very distinctly longer 

 than that of the female. The anterior tibiae are tridentate 

 in both sexes, but the upper tooth is smaller in the male. 



By a comparison of descriptions it will be seen that this 

 species is more shining, less deeply sculptured, and the upper 

 surface without pubescence. The sculpture of the thorax 

 and sides of elytra is notably different in the two. Here the 

 sides of the thorax are usually margined with cretaceous, 

 but in sepulcralis rarely so. The sexual characters here are 

 also better marked. 



Occurs in Kansas, Texas and Mexico. 



E. fascifera Lee. 



Black, shining, glabrous. Olypeus as broad as long, anterior angles 

 rounded, margin reflexed, nol emarginate, surface coarsely and densely 

 punctured. Thorax triangular, sides feebly annate, base emarginate in 

 front of scutellum, apex truncate, the middle of apical margin slightly 

 elevated in a tubercle, surface sparsely punctate, color reddish-yellow, with 

 a large triangular black space, or with the space replaced by four black 

 spols. Elytra vaguely bicostate, punctures sparse and coarse, on the disc 

 SUbocellate, color a reddish yellow, with a basal, median and sub apical 

 transverse dentate fascial black. Pygidiuin concentrically strigose. Body
