but conspicuous, whitish scales; white scales of the under surface 

 large and dense. Length (cf) 4.35 mm.; width 1.9 mm. Ken- 

 tucky inflaticollis n. sp. 



15 — Body notably broad. Oblong-suboval, only moderately convex, 

 black, the prothorax and antennal club dull rufous; scales of the 

 upper surface yellowish, fine but numerous and evident on the 

 pronotum, broader though linear, well separated, confused and 

 notably conspicuous throughout on the strial intervals; beak in the 

 female smooth, evenly arcuate and gradually tapering from base to 

 apex, distinctly longer than the head and prothorax, the antennae 

 inserted at the middle; prothorax nearly one-half wider than long, 

 widest very near the base, the sides thence slightly converging and 

 very feebly arcuate, more rapidly, obliquely rounding in apical 

 third; apex feebly constricted, half as wide as the base, the basal 

 lobe rather abrupt; punctures not very small, deep, circular, very 

 close but rarely in mutual contact, recalling somewhat the sculpture 

 in denticornis and related forms but finer; median smooth line 

 distinct and subentire; elytra with the sides slightly oblique and 

 very moderately arcuate, the apex broadly and obtusely rounded; 

 grooves deep but not very coarse; intervals subequal, about three 

 times as wide as the grooves, closely, coarsely and confusedly 

 punctate. Length ( 9 ) 4.4 mm.; width 2.1 mm. Missouri (locality 

 unrecorded) latiusculus n. sp. 



Body never very notably broad in outline 16 



16 — Species very small in size, with narrower prothorax and prominent 

 humeri. Rather narrow, convex, deep black throughout; squam- 

 ules of the upper surface small, sparse and inconspicuous, the larger 

 oval white scales beneath narrowly separated among themselves; 

 beak in the male stout, subopaque and strongly sculptured, nearly 

 straight, abruptly bent at base, almost half as long as the body; 

 antennae inserted near three-fifths, the tooth of the club basal and 

 very small; prothorax a third wider than long, widest very nearly 

 at the base, the sides feebly converging and broadly arcuate, grad- 

 ually more converging and arcuate before about the middle; apex 

 scarcely at all constricted, rather more than half as wide as the base; 

 punctures relatively somewhat coarse and deep but dense, with 

 traces of a smooth line centrally; basal lobe strongly binodulate at 

 apex; elytra with the oblique sides feebly arcuate to the rapidly 

 rounded but not very obtuse apex, two-fifths longer than wide, 

 much wider than the prothorax and nearly twice as long; grooves 

 moderate; intervals equal, two and one-half times as wide as the 

 grooves and somewhat coarsely punctato-rugose. Length (cf) 3.0 

 mm.; width 1.2 mm. District of Columbia. A single example. 



prominens n. sp. 



Species similarly very small, still narrower and with less prominent 

 humeri. Narrow and convex, more parallel, black, the tarsi rufo- 

 piceous; squamules of the upper surface rather small, indistinct 

 on the pronotum, whitish, less slender and evident though sparse 

 on the elytra, in one to two or three rows on the intervals; beak in 

 the male rather strongly, subevenly arcuate, longer than the head
