Baring 379 



little thicker and less smooth in the male, more declivous above at base 

 but not very abruptly, as long as the head and prothorax in the female; 

 antennal club rather large; prothorax shorter, smaller and more cylindric, 

 more than a fourth wider than long, the sides parallel and straight, ob- 

 lique and feebly rounding in nearly apical half; punctures strong, in 

 great part longitudinally rugulose, the smooth median line not very 

 distinctly defined, although somewhat tumid; elytra parallel, obtusely 

 rounded behind in more than apical third, one-half longer than wide, 

 nearly a fourth wider than the prothorax, the humeral callus moderate 

 though distinctly prominent; striae moderate, the intervals nearly flat 

 and rugulose, the squamules not oblique at the sides of the intervals; . 

 abdominal depression of the male with narrow, sparse squamules, the 

 terminal ligula very short and broadly angulate; subapical quadrate 

 polished spot involving also about half of the length of the fifth segment. 

 Length (cf 9) 2.8-3.1 mm.; width 0.9-1. i mm. North Carohna 

 (Black Mts.), — Beutenmiiller. 



Besides the much smaller size and more slerider form, this species 

 difTers from trinotata in the shorter and basaliy more parallel pro- 

 thorax, shorter, basaliy less declivous upper surface of the beak and 

 much shorter legs. In both species the pygidium of the male is 

 vertical and well developed, while in the female it is not only 

 smaller but more oblique and more concealed by the elytra. This 

 is by far the smallest species of the genus known thus far. 



The next four species are allied more or less closely to compacta 

 Csy., having a short and more convex form of body and notably 

 dense vestiture: 



Trichobaris brevipennis n. sp.— Oblong, convex, black, clothed with 

 brownish-white scales, which are parallel-sided irr form and very close, 

 though not in actual contact above, much larger and broadly oval, 

 whiter in color and in mutual contact beneath, a little smaller and less 

 dense though oval in the feeble male abdominal impression, the third 

 and fourth segments not entirely nude at the middle, having a thin hne 

 of hair-like scales at the apex; scutellum denuded, the two basal spots 

 of the pronotum very small; beak in the male short, thick, densely 

 squamose, angularly gibbous at base above and not quite as long as the 

 prothorax, the antennae compact; prothorax a third wider than long, 

 the sides feebly converging to beyond the middle, then more rounded and 

 gradually convergent to the apex, the constriction obsolete; punctures 

 very dense and not distinctly defined under the vestiture; elytra three- 

 sevenths longer than wide and parallel, rounding in about apical third, 

 almost a third wider than the prothorax and more than two and one-half 

 times as long, the rounded humeri but slightly tumid ; vestiture concealing 

 the sculpture, the striae indicated by fine and obscure partings, the scales 

 at the sides of the intervals not oblique; terminal abdominal ligula of 

 the male very minute. Length (cf) 4-5 mm.; width 2.15 mm. Cali- 

 fornia (southern— the locality not more definitely indicated).
