Antennae with short erect setse as usual, rapidly enlarged from the fourth 

 to the sixth or seventh joints. 

 Rufo-testaceous, the head and a large suhapical abdominal cloud blackish. 



fustiger 

 Black ; elytra slightly picescent, much paler at the humeri.

I have been unable to recognize sagulata Er., which is a species 

 apparently allied to convergens. but having pale antennae, with the 

 apical joint obtuse, and a subparallel abdomen, and minuta Sachse, 

 which is small, piceous, with the antennae toward base, legs, elytra 

 and anterior parts of the abdomen testaceous; the latter is probably 

 allied to nigriceps, but in that species the pronotum is very pale 

 and the elytra dark. The species described by me as Oxypoda 

 insignis is placed further on in the genus Anepsiota, allied to 

 Atheta, the anterior tarsi being four-jointed. 



O. COngmens. — Moderately stout and convex, parallel, brown, the head 

 and abdomen black, the segments paler at apex above and beneath ; legs and 

 antennae brown, the latter still paler toward base ; integuments alutaceous, 

 excessively minutely, densely punctate throughout, the pronotum slightly 

 less densely so and more shining toward base ; pubescence throughout very 

 short, fine and dense, subsericeous. Head orbicular, rather longer than wide, 

 but little more than one-half as wide as the prothorax, evenly convex ; eyes 

 moderate, distant from the base ; antennae long, fully attaining the middle of 

 the elytra, gradually and feebly incrassate, the second joint shorter than the 

 first or third, the latter nearly as long as the next two, tenth joint not dis- 

 tinctly wider than long, eleventh acutely conoidal, barely as long as the two 

 preceding. Prothorax transversely suboval, the base moving freely above the 

 elytra, fully three-fourths wider than long, the sides broadly arcuate, becom- 

 ing convergent and straighter in apical half, the base much wider than the 

 truncate apex, broadly, strongly arcuate, the basal angles almost completely 

 obliterated ; apical but slightly deflexed, broadly rounded ; disk feebly im- 

 pressed in the middle before the basal margin. Elytra moderately transverse, 

 at base narrower than, at apex equal in width to, the prothorax, sliglitly longer 

 than the latter ; sides distinctly divergent, broadly arcuate, especially near 

 the base ; humeri concealed ; disk very indefinitely and widelj'- impressed in 

 the middle toward base. Abdomen but slightly narrower than the elytra, much 

 longer than the anterior parts ; sides straight and parallel to the apex of the 

 fourth segment ; first three tergites impressed at base, successively less strongly; 

 fifth slightly longer than the fourth. Length 3.4 mm. ; width 1.0 mm.

The elytral humeri are frequently a little paler than the other 

 portions of the disk. This species, which appears to be widely dif-
