REVISION OF THE TENEBRIONIDvE OF AMERICA, 



E. aeutus. Black, subopaque, elongate oval, convex. Mead and thorax densely and coarsely punctured. 

 Thorax broader than long, narrower at apex, base truncate, sides broadly rounded anteriorly, sinuate near hind angles, 

 which are acute. Elytra oval, punctured in Irregular stria;, truncate at base, humeral angles acute and prominent. 

 Beneath coarsely and not densely punctured. Length .19 inch. 



Nebraska, collec. Leconte. Can with difficulty be distinguished from ate,r except by 

 the margin and angles of thorax. 



E. obesus, Lee, Ann. Lye 5, p, 188 (Kurymetopou); eonvexus, Lee., N. Spec. 8, p. 107. 



I unite the above two species, being unable to discover any difference save a little 

 more rounding of the sides of thorax. 



From California, New Mexico and Nebraska. Length .20-26 inch. 



E. obtusus, Leo., N. Spec, p. 107. 



This is much flatter than any of the smaller species, more elongate and with the sides 

 of the thorax more strongly rounded and narrower at base than middle. 

 Middle California. Length .30 inch. 



E. rug os us, Motsch., Bull. Mosc. 1845, I, p. 75. 



Is unknown and the description unrecognisable. 

 From Sitkha. 



TRIBE VI BATULIINI. 



Mentum large, concealing ligula but exposing the bases of the maxilla?, and with a 

 broad gular peduncle. Middle coxa? entirely enclosed by sterna, trochantin invisible. In- 

 tercoxal process of abdomen triangular. Legs short, tibial spurs distinct. Tarsi short, 

 spinose beneath. 



I have removed Anepsius from the tribe, as it has the middle coxae open externally 

 and the trochantin visible. It will be found in the next sub-family. The single genus 

 Batulius constitutes this tribe, containing but two species. 



BATULIUS, Lee. 

 Batulius, Leo., Ann. Lye. V. 148. 

 B. set os us, Lee., Ann. Lye. 5, 148. 



Length .14 inch. 



Occurs in the Deserts of the Gila. 



B. r ot undicollis, Lee, Aim. Lye 5, 14.8. 



These are both small testaceous insects. The former is the larger, more robust and 

 sparsely covered with yellowish hairs. The sides of the thorax are broadly rounded and 

 the disc more convex. In rolundicoUis the thorax is shorter, somewhat narrower behind, 

 and less strongly rounded on the sides. 



Length .10 inch. 



Occurs with the preceding.
