Elytra about twice as long as wide, one-fourth wiiler than thorax, humeri broadly 

 rounded ; sides i>€arly parallel for two-thirds their length,, then rather abruptly 

 narrowed and broadly rounded to apex. Stria; rather fine, nioilerately impressed, 

 punctures approximate. Intervals broad, nearly flat, each bearing a series of fine 

 setigerous punctures ; setrt short but bristle-like. .Surface densely clothed with a 

 mixture of cupreus, pearly and whitish scales, the paler ones forming a di.igonal 

 chevron on the fourth, lifth, sixth and seventh intervals. This paler band occupies 

 rather more than the median third of the elytra, its anterior margin gradually 

 diverging from suture toward the humeri where it forms a continuation of the 

 marginal vitta of the thorax. A small ill-dclined while patch, on the second and 

 third intervals, slightly in front uf chevron ; scutellum large, subquadrate, covered 

 with elongate, silvery-while scales. Ventral surface and legs sparsely clothed with 

 pearly scales, which are more hliform than those of the elytra. Tibia: denticulate 

 and setigerous along their inner margin. Anterior tarsi dilated. Last ventral un- 

 impressed. Length 5. Smni. ; .25 iiuh.

Anthonomus Dentoni, s[). nov . Llongate, subelliplic , unitorm rufous, 

 shining ; sparsely clothed with pure white, recumbent squamiform hairs. Beak 

 long, rather slender, shining, with large confluent punctures. Scrobes deep and 

 straight ; antenn;e slender, inserted about two-fifths from apex, funicle seven- 

 jointed, first joint long and stout, second much more slender, slightly longer than 

 third, third to seventh sub-equal, with many long bristling hairs, club elliptical, 

 faintly annulate. Head subconical, shining, frontal fovea large and deep. Eyes 

 dark rufopiceous, rather convex. Thorax slightly wider than long, rather strongly 

 narrowed in front and constricted at apex, sides broadly rounded ; surface 

 coarsely punctured, each puncture bearing a whiti.sh scale like recumbent hair, 

 pubescence becoming more dense near side margins and forming ill-defined white 

 vitta;. t^lytra oblong, slightly wider than thorax, nearly three times as long as 

 wide, humeri rather prominent ; sides feebly narrowed, and gradually rounded 

 from near middle to apex. Surface deeply striate, punctures large and deep, 

 approximate, intervals somewhat convex finely punctured and bearing short recum- 

 bent seta;. The peculiar squamiform hairs become much more dense just before 

 apical third, where they form a conspicuous band, widest near suture ; humeri and 

 scutellum with denser patches of similar white hairs, ventral surface sparsely and 

 rather coarsely punctured with a few white hairs. Legs not very robust, coarsely 

 but sparsely punctured, femora clavate, anterior femora with a large triangular 

 tooth, median with tooth small but very acute, posterior femora unarmed. Tibia: 

 slender, anterioi curved near base, sinuate. Length 3 mm.; .12 inch.
