punctures, the punctures of the strife and internals each bearing a short, fine, recum- 

 bent pale hair. Body beneath concolorous, pro- and metasternum coarsely, sparsely 

 punctate, abdomen sparsely punctured each puncture bearing a pale hair. Legs paler. 

 Length, 2-2.25 ni™- 



Two specimens, Brownsville, Texas (S. Tomas -and Fort Brown) 

 in the Museum of the Brooklyn Institute of Arts and Sciences, cotypes 

 in the Nat. Museum collected by C, H. T. Townsend and E. A. 

 Schwarz. This can only be compared with puberulus Casey, from 

 which it differs in coloration, more coarsely punctured thorax not 

 subacute elytral apices and more convex elytra. 



Tomarus chamgeropis, new species. 



Type. — No. 8158, U. S. National Museum. 



Oval, black to piceous, apex of elytra paler, antennae fulvous. Head sparsely 

 finely punctured, antenna slender, fulvous, fourth and fifth joint equal. Thorax much 

 narrower than the elytra, slightly wider than long, front angles broadly rounded, 

 sides nearly straight, hind angles rectangular, acute, base sinuate, basal foveas deeply 

 impressed. Elytra shining black, apex paler, about one third broader at base than 

 the thorax, arcuate at sides and much narrowing to apex, surface rather coarsely but 

 not densely punctured, punctures obliterated at apex, which is smooth and shining. 

 Beneath piceous or paler, finely punctate, abdomen sparsely pubescent. Legs fulvous. 

 Length, 1.5 mm. 



Brownsville, Texas, three specimens in the U. S. Nat. Museum 

 collected by E. A. Schwarz whose MSS. name I have used. Cotypes 

 in the Museum of the Brooklyn Institute through the kindness of Mr. 

 Schwarz. 



Type. — No. 8159, U. S. National Museum. 



By the nearly uniform color and narrow thorax this species is re- 

 lated to niger Sharp from Panama from which it is distingushed by the 

 pale antennae and legs, the fifth antennal joint equal to the fourth, the 

 distinct basal foveas of thorax and the more coarsely punctured elytra. 

 The elytral punctures bear erect hairs, which seem to be on the 

 thorax shorter and finer. 



Teretriosoma chalybasum Horn. 



With specit^iens, which agree with Dr, Horn's description and 

 type, occurred one which has the front convex to the middle, at this 

 point transversely sulcate, fringed with fine pale hairs, and below the 

 transverse sulcation the surface deeply excavated, similar to sexualis 

 described below and the Mexican cavi/roJis. While not able to abso- 

 lutely prove it, yet I am convinced that it is the male of chalybceum,
