above has the fifth ventral evenl}^ and strongly arcuate at apex. 

 The single specimen from Austin, which I regard as the male, 

 has the elytra relativel}' shorter and broader, with the fifth ven- 

 tral somewhat narrowly truncate at tip. 



It is singular that Dr. IjeConte should have failed to observe 

 the strong aflfinity of this species with those which he placed in 

 Dasytes ; there is absolutely no single point of resemblance with 

 Dolichosoma foveicoUis, with which it was associated by that 

 author. 



6. D. degeiier n. sp. — Elongate, siiboval, convex, polished, black, the 

 elytra more or less paler and piceous; femora pieeons-black, the trochanters, 

 tips of the femora, tibise and tarsi plceo-ruf oias ; antennae dark piceous, slightly 

 paler toward tip; pubescence coarse, cinereous, decumbent and distinct but 

 sparse. Head three-fourths as w'ide as the prothorax, transverse, feebly con- 

 vex, strongly reticulate and obsoletely punctulate, the frontal impressions 

 feeble and widely separated; epistoma short, the labrum small, transverse and 

 strongly rounded, the mandibles and labrum somewhat pale in color; eyes 

 small but rather prominent; antennse short and slender, distinctly longer 

 tlian the prothorax, the outer joints wider, the penultimate transverse. Fro- 

 thorax three-fourths wider than long, the sides strongly rounded at the base, 

 thence convergent and nearly straight to the apex, the latter narrower than 

 the base which is broadly arcuate; angles obtuse and blunt; disk finely and 

 sparsely punctate, feebly reticulato-rugose near the sides, the submarginal 

 line normal. Elytra rather short, not quite three-fifths longer than wide, 

 scarcely two-fifths wider than the prothorax, the sides parallel; apex some- 

 what obtusely ogival; punctures fine but strong, moderately close, the inter- 

 spaces polished. Under surface deep black and sparsely pubescent through- 

 oiit. Length 1.5 mm.; width 0.75 mm. 



Arizona (Benson). Mr. Dunn. 



The t3^pe above described seems to be a female, the male hav- 

 ing the sides of the prothorax broadh^ arcuate throughout and 

 nearly parallel, with the fifth ventral broadly and feebly arcuato- 

 truncate at tip. There is some variability displayed in the six 

 specimens before me, the upper surface l)eing deep black through- 

 out in some, and, in one example, the prothorax becomes twice as 

 wide as long and almost fully as wide as the elytra ; but I believe 

 that this specimen ma}- possibly represent a closel}' allied though 

 distinct specific form. The specimens are all in rather poor 

 condition. 



7. D. elegiiiitiiliis n. sp. — Stout, suboval, strongly convex, moderately 

 shining, black, tlie legsand antennae black throughout; pubescence moderately 

 long, closely decumbent, coarse, cinereous-white, dense, even and very con-
