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- 

 pubesceut. 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, 

 blaik, 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 ; antennse 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 

 perhai)s most strongly allied, and with strikingly different autennal 

 structure.
