least quite different from this supposed example of testaceipes in 

 general outline of the body: 



*Nicentrites hidalgoanus n. sp. — Oblong-suboval and convex, black, 

 densely clothed with sublinear scales, brownish-white above and white 

 beneath, the legs, antennae and distal part of the beak bright red, the 

 first with finer, sparse squamules; beak in the male rather short and 

 thick, evenly and feebly arcuate, not as long as the head and prothorax 

 and closely squamulose to near the apex, the antennae at three-fifths; 

 prothorax two-fifths wider than long, the sides parallel and feebly arcuate 

 in about basal, rounded and converging in apical, half, the apex barely 

 at all constricted and half as wide as the base; punctures moderate and 

 close-set, but clearly defined and separated; scutellum small, densely 

 albido-squamose; elytra ovulate, a fifth wider than the prothorax and 

 nearly two and one-half times as long, one-half longer than wide, grad- 

 ually somewhat narrow at apex, the humeral prominences very feeble; 

 striae rather fine but deep; intervals flat, subequal, four or five times as 

 wide as the striae and finely, confusedly, rather closely punctate; male 

 abdomen impressed and less squamulose medio-basally; anterior tibiae 

 with the terminal spur conspicuous and very sharp. Length (c?') 3.15 

 mm.; width 1.25 mm. Mexico (Hidalgo). One example. 



Differs from the male example of testaceipes, at hand, in its larger 

 size, more parallel form, larger and more transverse, laterally more 

 rounded prothorax, with more distinct and entire median smooth 

 line and in its more elongate and apically more gradually narrowed 

 and rounded elytra. The flattening of the upper surface in testa- 

 ceipes, alluded to by Mr. Champion, does not accord with my 

 example, the surface of which is as strongly convex as in any 

 Nicentrus. 



Gl3rptogeraeus n. gen. 

 The type of this proposed genus is Centrinus punctatissimus Boh., 

 of Cuba. The body is subrhomboid-oval, convex and totally 

 nude, excepting a very few small spots of aggregated white scales 

 and a few others sparsely scattered, also small dark decumbent 

 setse from the elytral punctures as in Pachybaris. The beak is 

 thick and strongly sculptured, feebly tapering apically and differing 

 but little in the sexes, being a little more tapering and smoother 

 apically in the female. The antennae are inserted very slightly ( 9 ) 

 or much (cf) beyond the middle, and the joints, after the elongate 

 first of the funicle, are all short — an important character dis- 

 tinguishing it from Centrinaspis. The pronotum is extremely 

 coarsely punctate, the elytral grooves moderate and the intervals
