along the middle and lateral edge of each elytron, also dense and more yellow- 

 ish along the sutural interval; recurved fulvous setse rather abundant; on 

 the under surface the scales are elongate-oval, whitish and dense. He<id and 

 beak very densely, finely squamulose, the latter short, very stout, strongly 

 tapering from base to apex, with the portion beyond the antennae very thin, 

 nude and shining, feebly arcuate, in the male not more than three-fourths as 

 long as the prothorax, with the antennse inserted just behind apical third, the 

 first joint of the funicle very stout, pedunculate at base, not as long as the 

 next three, second one-half longer than the third, seventh a little larger than 

 the sixth. Prothorax very nearly as long as wide, the sides parallel and nearly 

 straight in basal two-thirds, then broadly rounded, convergent but scarcely at 

 all constricted to the apex, the latter about one-half as wide as the base ; disk 

 densely, not coarsely punctate. Elytra at base ratlier more tlian one-fourth 

 wider than the prothorax, not quite three times as long, the sides parallel and 

 nearly straight in basal three-fifths ; strise very fine. Legs moderate, the hind 

 femora feebly dentate, emarginate near the apex. Lengtli 2.8 mm,; width 

 1.3 mm.

The single male before me represents a species allied to semi- 

 sqiiamosus, but differin.ij- in its more robust form, much more abun- 

 dant and whiter scale-like plates of the elytra, relatively narrower 

 apex of the prothorax, more rapidly and finely acuminate beak, and 

 in several other characters. The fifth ventral segment has in the 

 center a small deep punctiform fovea, which is not visible in the 

 male of semisquamosus.

10 T. prolixiIS n. sp. — Oblong-elongate, convex, blackish, tlie antennfe 

 and tip of beak paler ; vestiture very dense throughout, consisting, on the 

 pronotum, of long slender subrecumbent and strigose squamules, pale fulvous 

 in color but whitish along the middle and near the sides toward base, not 

 intermixed with more slender and erect setae but with a few broad non-strigose 

 scales in the whitish areas, though only near the base ; on the elytra the 

 scales are very large, dense, rounded, finely granulose in texture, widely im- 

 bricated and dark reddish-gray in color, each interval with a single uneven 

 series of very coarse strongly recurved reddish pointed setje ; the under sur- 

 face is densely clothed with elongate-oval concave and whitisli scales. Head 

 squamose ; eyes rather large, almost perfectly circular ; beak in the male thick, 

 densely hispido-squamose and with a prominent tuft above each eye, almost 

 straight but bent at base, rather rapidly narrowed, glabrous and shining be- 

 yond the antennse, barely equal in length to the prothorax ; antennse inserted 

 at apical two-fifths, the first funicular joint rather longer than the second and 

 third, which are subequal and each distinctly longer than wide. Prothorax 

 one-fourth wider than long, the sides just visibly convergent and broadly, 

 feebly arcuate from the base nearly to the apex, then ratlier abruptly, deeply
