arcuate, bjcoming parallel behind the middle and broadly sinuate near the 

 apex, which is truncate and quite distinctly less than one-half as wide as the 

 base, the latter transverse, the lobe less than one-third the width, rounded 

 and rather prominent ; mes-epimera strongly exposed from above in the basal 

 reentrant angle ; disk somewhat coarsely, very densely, rather rugosely punc- 

 tured, the impunctate line only narrowly and indefinitely traceable toward 

 the middle. Scutellum small, quadrate, glabrous, impressed along the middle. 

 Elytra slightly wider than the prothorax and twice as long, the sides strongly 

 convergent, feebly and evenly arcuate throughout, the apex narrowly, evenly 

 rounded, the humeral callus not distinctly prominent ; disk deeply, not very 

 coarsely striate, the intervals from two to three times as wide as the grooves, 

 densely, confusedly and rugosely punctured. Abdomen broadly, feebly im- 

 pressed and more sparsely squamose in the middle toward base. Prostemum 

 with a large, moderately deep impression, subglabrous at the bottom, and with 

 a short stout erect process before each coxa, the coxae rather large and sepa- 

 rated by four-fifths of their own width. Length 2.9 mm. ; width 1.35 mm. 



District of Columbia. 



The typical representative above described is a male. The species 

 is altogether distinct from any other here noted, and may be known 

 at once by the pale coloration of the integuments and the ochreous 

 scales. 



14 Centrums perscitus Herbst — Kafer, VII, p. 28 (Curculio). 



Oval, convex, piceous-brown, the elytra rufous; vestiture not 

 very dense, ochreous-yellow, consisting of closer and broader scales 

 beneath, and on the upper surface of narrow squamules which are 

 abruptly much denser along the sides of the pronotum, the elytra 

 also with a few larger whiter and very widely dispersed scales. 

 Beak rather short and thick, evenly, strongly arcuate, as long as the 

 head and prothorax in the female, similar but a little shorter and 

 thicker in the male, the antennae rather short, inserted at or just 

 behind the middle, the first funicular joint robust, fully as long- as 

 the next three, second not twice as long as wide; club rather large, 

 oval, as long as the five preceding joints combined, densely pubes- 

 cent and indistinctly annulated. Prothorax fully two-thirds wider 

 than long, the sides feebly convergent and very slightly arcuate to 

 apical third, then broadly rounded convergent and broadly sinuate 

 to the apex; disk very densely, not coarsely punctate. Elytra 

 conoidal, narrowly rounded at apex, a little wider than the pro- 

 thorax and sensibly more than twice as long, the striae fine but deep, 

 the intervals densely, confusedly punctato-rugulose, flat, three to 

 four times as wide as the grooves. Prosternum in the male narrowly,
