fused, differs from the European sjoectabilis in its much smaller size 

 and far less distinct basal angles of the prothorax. 



O. COnvergens. — Rather broad, siibfusiforra, black ; four basal joints 

 of tlie antennae and the legs throughout pale; proiiotum gradually rufesceut 

 toward base ; elytra and apices of all the ventral segments pale brownish- 

 rufous ; integuments alutaceous, extremely finely feebly and densely punctate 

 throughout, the head and pronotum rather the least densely punctate and 

 more shining ; pubescence short, very dense throughout, sericeous on the 

 abdomen, the latter bristling with stiff setae toward apex. Head wider than 

 long, orbicular, evenly convex, scarcely more than one-half as wide as the 

 prothorax ; eyes rather large, extending to within one-half their length of 

 the base ; antennae feebly incrassate, as long as the head and prothorax, the 

 first three joints equal in length, fourth subquadrate, five to ten subequal, a 

 little wider, slightly transverse, eleventh rather acutely conoidal, barely as 

 long as the two preceding. Prothorax fully two-thirds wider than long, the 

 sides strongly convergent, broadly evenly and strongly arcuate from base to 

 apex ; base fully three-fourths wider than the apex, broadly, strongly arcuate, 

 the apex transversely truncate ; basal angles obtuse and rather blunt bat 

 distinct ; disk just visibly wider at basal third than at base, not distinctly 

 impressed. Elytra at base slightly narrower, at apex a little broader, than 

 the prothorax, distinctly longer than the latter ; sides perceptibly divergent 

 and feebly arcuate from base to apex ; humeri completely concealed ; external 

 apical sinuations narrow and deep ; disk scarcely at all impressed. Abdomen 

 at base distinctly narrower than the elytra, at the apex of the fifth segment 

 one-half as wide as the latter ; sides perfectly straight ; border gradually 

 thicker and deeper from apex to base ; two basal tergites very feebly impressed 

 along the basal margin ; fifth nearly as long as the third and fourth together. 

 Length 3.0 mm. ; width 0.9 mm. 



New York (Catskill Mts.). 



The abdomen is evenly narrowed from base to apex, and the fifth 

 segment is unusually long. This species cannot be very closely 

 allied to sagulata, although it approaches that species, according to 

 description, closer than any other form here described. 



O. impressa. — Moderately wide and convex, black throughout, the 

 elytra extremely indistinctly picescent ; antennae black ; legs rafo-piceous ; 

 ventral plates slightly and narrowly pale at apex ; integuments but feebly 

 shining, the head, pronotum and elytra finely and densely but rather dis- 

 tinctly punctate, the abdomen much more minutely feebly and excessively 

 densely so ; pubescence rather coarse, dense, semi-erect anteriorly, excessively 

 minute and dense on the abdomen, each tergite, in addition, with a transverse 

 apical series of long setae. Head orbicular, evenly convex, nearly as long as 

 wide, slightly more than one-half as wide as the prothorax ; eyes rather large, 

 at less than one-half their length from the base ; antennae moderate in length, 

 slightly longer than the head and prothorax, rather slender and feebly in-
