PTEROSTICHIN/E 339 



the subapical sinus is feeble though evident. The antennae and 

 legs are slender, the head moderate, with rather prominent eyes, 

 the thoracic fovese single and linear, the prosternal process unmar- 

 gined, the hypomera narrow, and the metasternum and latero-basal 

 parts of the abdomen are more or less punctured. The last ventral 

 segment has a single apical puncture at each side in the male, two 

 in the female. LeConte alludes to a very faint elevation toward the 

 abdominal apex in the male, but I have been unable to perceive 

 anything at all definite in this regard. The fourth palpal joint is 

 longer than the third, gradually pointed apically, and the mentum 

 tooth is long and with the apex blunt. The species will probably 

 prove to be somewhat numerous, the five at hand being easily sep- 

 arable as follows : 



Elytral striae completely impunctate 2 



Elytral striae punctured ; body very small 5 



2 Anterior tarsi of the male somewhat strongly dilated, the second and 

 third joints transverse. Body moderately stout and convex, pol- 

 ished, deep black, piceous-black beneath, the discal parts of the ab- 

 domen and the legs rufous; head not quite two-thirds as wide as the 

 prothorax, the eyes rather large, moderately prominent; anterior 

 sulci parallel, deeply impressed; antennss testaceous, slender, nearly 

 half as long as the body; prothorax rather large, a fourth wider than 

 long, the base transverse, two-thirds the maximum width and fully 

 as wide as the deeply sinuate apex, widest near apical third, the sides 

 strongly, subcircularly rounded, abruptly sinuate at base, abruptly 

 reflexed, the basal angles rather less than right, sharp and slightly 

 prominent; apex imperfectly margined; impressions feeble; stria 

 deep, subentire; basal parts punctate within the long deep foveae; ely- 

 tra very evenly oval, the sides not more strongly rounded basally, 

 one-half longer than wide and two-fifths wider than the prothorax; 

 striae very deep, the scutellar long, deep, joining the first, the inter- 

 vals strongly convex. Length (cf ) 8.5 mm.; width 3.3 mm. In- 

 diana atronitens n. sp. 



Anterior tarsi of the male feebly dilated, the triangular second joint not 



wider than long 3 



3 Hind body strongly inflated, the sides of the elytra more rapidly 

 rounding basally. Color blackish-piceous, polished in both sexes; 

 under surface and legs dark rufous; head fully two-thirds as wide as 

 the prothorax, with moderately large and prominent eyes, the an- 

 terior sulci feebly converging; antennae rufous, rather long and slen- 

 der; prothorax barely at all wider than long, the base (cf ) fully as 

 wide as the apex, or ( 9 ) somewhat narrower; apex sinuate; sides 

 finely, sharply reflexed, strongly rounded, at base nearly as in the 

 preceding, the angles slightly acute and prominent, scarcely more 

 than right in the female; surface and foveae nearly as in atronitens;
