342 Coleopterological Notices, V. 



obtuse but distinct, not blunt ; disk strongly convex, finely beaded at tbe 

 sides and base, very obsoletely impressed in the middle before the base. 

 Elytra much wider than long, one-fourth wider and two-fifths longer than the 

 prothorax ; sides parallel, feebly arcuate ; humeri slightly exposed. Abdomen 

 longer than the anterior parts, very nearly as wide as the elytra ; sides parallel, 

 just visibly arcuate ; border moderate ; under surface densely, coarsely fulvo- 

 pubescent. Legs clothed sparsely with long hairs, the upper sides of the 

 femora and trochanters polished, impunctate and glabrous. Length 2.0 mm. ; 

 width 0.7 mm. 



District of Columbia. 



One of the three specimens has the pronotum also rufous, and 

 another has the pronotum and elytra black ; this latter specimen 

 has the prothorax somewhat smaller, the elytra fully one-third 

 wider than that part, and with longer, more erect pubescence. It 

 is probably a variable species, with considerable sexual disparity 

 also, although the sexual marks at the apex of the venter are appa- 

 rently very feeble, and there are none on the tergum in the examples 

 before me. 



T. setigera n. sp.— Moderately stout and convex, thick, subparallel, 

 black, the legs and antennae toward base pale, flavescent ; integuments feebly 

 reticulate throughout but polished, the head and pronotum finely, sparsely 

 punctate, the elytra more strongly but simply and not very densely so, the 

 abdomen sparsely and asperately ; pubescence long and conspicuous. Head 

 wider than long, only slightly but distinctly narrower than the prothorax ; 

 eyes rather prominent ; tempora equal to them in length and feebly convergent 

 and arcuate to the base ; surface flattened ; antennae strongly setose, feebly, 

 gradually incrassate, about attaining basal third of the elytra, the first joint 

 much longer than the second, the latter thicker and a little longer than the 

 third, fourth slightly wider than long, subquadrate, tenth twice as wide as 

 the fourth and rather strongly transverse. Prothorax transversely subrect- 

 angular, nearly two-thirds wider than long ; sides parallel, broadly arcuate ; 

 base and apex subequal, broadly, strongly arcuate ; basal angles slightly 

 obtuse and distinct ; disk strongly, evenly convex, very feebly impressed in 

 the middle toward base. Elytra transverse, about one-fourth wider and nearly 

 one-half longer than the prothorax ; sides quite perceptibly divergent from 

 the base ; disk feebly convex. Abdomen, at the middle, as wide as the elytra, 

 but at base distinctly narrower, a little longer than the anterior parts; sides 

 parallel and arcuate ; segments short, transverse, all equal in length, the 

 first three strongly, subequally impressed at base; border strong. Length 

 1.65 mm. ; width 0.6 mm. 



New Jersey. 



Smaller and rather more slender than compacta, to which it is 

 perhaps most strongly allied, and with strikingly different antennal 

 structure.
