gent, the apex transversely sinuato-triincate with the angles not 

 rounded, and, along its surface there is a low rounded ridge, extend- 

 ing to the apex and occupying one-third of its entire subapical width. 

 The differences between this and the preceding species are almost 

 certainly subgeneric ; the general appearance of thoracica is not 

 unremindful of Oxypoda. 



B. "bipartita n. sp. — Stout, subfusiform, rufo-piceous in color, the head 

 and abdomen darker and blackish ; elytra scarcely visibly clouded with 

 blackish along the suture and toward the flanks ; legs pale flavate through- 

 out ; antennae fuscous, paler toward base, the eleventh joint also paler except 

 toward its base ; integuments strongly shining, the head finely, strongly, not 

 very densely, the pronotum finely, strongly, evenly and extremely densely 

 punctate ; elytra finely, still more densely, subasperately punctate, the abdo- 

 men much more coarsely, very densely and subrugosely ; pubescence coarse, 

 stiff, dense, short, pale fulvous and distinct, finer darker sparser and incon- 

 spicuous on the abdomen. Head small, orbicular, not as long as wide, scarcely 

 more than one-half as wide as the prothorax, the eyes large, elongate, at much 

 less than one-half their length from the base ; infralateral carina strong, 

 entire ; vertex evenly convex ; antennae short but only slightly incrassate, 

 not quite as long as the head and prothorax, the second and third joints equal 

 in length, the first longer and stouter, fourth but little wider than long, six 

 to ten equal, slightly though distinctly transverse, eleventh subconical, rather 

 acute, somewhat longer than the two preceding. Prothorax not quite twice 

 as wide as long, the sides strongly convergent, very evenly and moderately 

 arcuate from base to apex ; base strongly arcuate, four-fifths wider than the 

 apex, which is less strongly arcuate; basal angles very obtuse, rounded; 

 apical equally obtuse but less broadly rounded ; flanks greatly deflexed, the 

 disk completely unimpressed, the fine basal bead distinct. Elytra at base 

 equal in width to the prothorax, which is widest at its base, toward apex 

 quite distinctly wider than the prothorax, equal in length, strongly trans- 

 verse, the humeri concealed ; sides feebly divergent, evenly and unusually 

 strongly arcuate throughout ; disk flattened toward the middle. Abdomen 

 quite distinctly longer than the anterior parts, at base equal in width to the 

 elytral apex ; sides feebly convergent and straight to the apex ; first two seg- 

 ments only feebly impressed but not more coarsely punctured at base ; fifth 

 distinctly longer than the fourth ; border thick, moderately deep. Legs short ; 

 posterior tarsi slightly shorter than the tibiae, the basal joint barely as long as 

 the next two and slightly longer than the last. Length 3.7 mm. ; width 1.3 mm. 



Texas (Galveston). 



The mesosternal process is moderate in width and extends to the 

 very apex of the coxse, the apex subtruncate with rounded angles, 

 the median carina entire, strongly elevated and finely compressed. 

 This species greatly resembles an Oxypoda in outline. The contrast
