TRIBE XVIII. BARIXI. 387 



along apical margin of thorax; those of elytra larger, elongate-oval, 

 each lying within a large oval puncture. Beak nearly as long as ely- 

 tra in female, antennse inserted beyond its middle, second joint of 

 funicle two-thirds as long as first, slightly shorter than the next two. 

 Thorax one-half wider than long, sides broadly, nearly evenly curved 

 from base to apex, disc rather coarsely, deeply and densely punctate. 

 Elytra wider and about twice as long as thorax; stria? coarse; intervals 

 flat, coarsely punctate. Prosternum with a deep, transverse oval pit 

 just behind the apical margin in both sexes; basal joint of club in 

 male with a short, acute, erect tooth. Length 4.5 5 mm. 



Described from North Carolina, Colorado and Texas. Col- 

 lected on Rndhcclila in May, and on Anof/ra pallida Lindl. in

Small oblong-oval, densely scaly species having the inner edge 

 of mandibles straight, distinctly notched near apex; beak slightly 

 longer than head and thorax, very slender, strongly curved ; an- 

 tenna? inserted near its basal third, scape short, reaching almost 

 to eye, first joint of fnnicle as long as the next three, second but 

 slightly longer than third, club oval, pointed, its basal joint un- 

 usually large; prosternum of female deeply channeled along the 

 middle, that of male with a still deeper elongate-oval excavation 

 and a short, abruptly bent horn before each coxa; scutellmn 

 very small, densely scaly; pygidium completely covered in both

589 (11,170). CENTRINOPUS HELVIKUS Casey, 1892, 602. 



Oblong-oval, convex. Head, thorax, under surface and often the 

 femora piceous; elytra reddish-brown; antennse, tibia? and tarsi paler; 

 above rather densely clothed with clay-yellow hair-like scales, those of 

 thorax arranged transversely, and on sides and median line condensed 

 to form narrow stripes; those of elytra somewhat broader and more 

 dense along the third, fifth and seventh intervals; under surface very 

 densely clothed with larger, oval white scales. Beak shining, almost 

 impunctate above, finely striate and rather coarsely punctate on sides. 

 Thorax one-third wider than long, sides nearly straight and feebly con- 

 verging from base to apical third, then broadly rounded and more strongly 

 converging to apex; disc densely, rather coarsely punctate. Elytra at 

 humeri about one-fifth wider than thorax, thence gradually narrowing 

 to the rounded apex; striae fine, rather deep; intervals flat, the alter- 

 nate ones slightly wider, and with three instead of one or two irregular 

 rows of scales. Length 2 2.7 mm.
