cariiiatc ami closely and coarsely ]niiictui'ed, except near the apex; antenna; 

 shnider, inserted ( ^ and 9 ) one-third from the apex, scape impungiug against 

 the eye, first joint of fuuicle moderately stout, second long and slender, fully as 

 long, or longer than the first, joints 3 4 shorter, outer three joints transverse and 

 slightly wider. Eyes feebly convex with slightly raised supra-orbital ridges, 

 separated nearly as widely as the width of the beak. Head densely and coarsely 

 punctured, front flattened ; prothorax one-half wider than long, rounded on the 

 sides and feebly constricted at the apex, about one-fourth wider at the base than 

 at the tip ; lateral tubercles very small, obtuse, dorsal sulcus entire, more deeply 

 impressed behind, a transverse, ill-defined imjjression each side behind the middle, 

 surface coarsely punctured, punctures crowded on the sides. Elytra oval, about 

 one-fourth wider at the base than the prothorax, sides rounded, strife wide, deep, 

 closely and (hoarsely punctured, interspaces subconvex. alternately a little wider, 

 rugose, the wider interspaces with pale, piliform scales, scutellar spot very con- 

 spicuous, cardiform ; pygidium like the underside, rather coar.sely and closel.y 

 punctured ; femora subclavate, tibiae widtmed at the apex, third tarsal joint 

 broadly bilobed, fourth long, ])rojecting the length of the preceding joint, claws 

 armed with a strong tooth or.e-half the length of the claw. Length 3.5-4.0 mm. ; 

 0.14-0.16 inch. 



% . Fifth ventral segment broadly emarginate, shorter than the two preceding 

 segments together, anterior tibia; uuguiculate at the apex. 



9 . Fifth ventral rounded, longer than the two preceding segments.

This species is known in our lists and collections as pericarpius, 

 and it is not without hesitancy that I propose a new name for a fairly 

 well-known species. In size and general appearance it agrees well 

 with the European species, but difiers from it in the followijig points : 

 1. beak carinate ; this is constant, though varying in degree in all 

 the numerous specimens before me, while in eight European speci- 

 mens of pericarpius from different localities a slight indication of a 

 carina exists only in two specimens ; 2. the curved imj)ression at the 

 base of the rostrum is not noticeable in pericarpius ; 8. the fourth 

 tarsal joint projecting about the length of the third joint, whereas 

 in pericarpius the third is relatively shorter, the fourth })rojects 

 distinctly more than the length of the former. 



R« I>yi*i*liO|>US Boh.— Suboval. piceous, antennif, and legs paler, clothed 

 above with a coarse brownish pubescence, variegated in varying proportion with 

 whitish piliform scales, underside clothed with whitish scales which are more 

 dense on the sterna and their side pieces. Beak longer than the head, cylindrical, 

 feebly curved, carinate, densely punctured and scaly in its basal half, finely punc- 

 tured, shining and widened towards the apex, fir.st joint of funicle stout, second 

 elongate, longer than the third, outer joints a little wider. Eyes slightly convex, 

 with feeble supra-orbital ridges, separated above nearly the width of the beak. 

 Head densely punctured, squamose, slightly concave between the eyes: prothorax 

 less than one-half wider than long, narrowed in front, feebly rounded on the
