constricted, the apex rather more than one-half as wide as the base. Elytra 

 one-third wider than the prothorax and not quite three times as long, the 

 sides parallel and straight in basal two-thirds ; apex obtuse, with a small 

 sutural notch. Legs long and rather slender, the hind femora feebly, obtusely 

 prominent beneath at apical fourth. Length 3.3 mm.; width 1.35 mm.

The six-jointed antennal funicle isolates this species from all 

 others which it most resembles in external aspect. The single type 

 specimen is a male, and has the fifth abdominal segment scarcely 

 impressed but longer than the two preceding together, the second 

 suture flexed strongly backward at the sides extending a little be- 

 yond the anterior margin of the fourth segment, the third and fourth 

 sutures scarcely at all bent at the sides.

11 T. variegatlis n. sp. — Robust, oblong, rather convex, blackish, the 

 antennae and beak slightly paler ; vestiture above not very dense, on the pro- 

 notum not altogether concealing the punctures and consisting of short very 

 coarse pointed fulvous and white setae, replaced by large white scales in the 

 middle near the base and toward the sides ; on the elytra, of very short stout 

 subrecumbent seta?, fulvous and whitish in color, white and denser on the 

 subapical umbones, and replaced by large imbricated white scales in a small 

 elongate spot behind the scutellum. also more narrowly and indistinctly, in 

 a small sutural line at the apex ; under surface and legs clothed throughout 

 very densely with white scales, sometimes feebly variegated with pale brown. 

 Head and beak extremely densely squamose, the scales above usually dark 

 ochreous-red, but whiter along the sides, the impressed line behind the eyes 

 distinct, the eves wider than long ; beak extremely thick but rapidly tapering 

 and subglabrous toward the tip, feebly arcuate, about as long as the prothorax 

 in the male, with the antennae inserted at apical third, scarcely longer in the 

 female but with the antennae inserted just beyond the middle ; antennae mode- 

 rate, the first funicular joint fully as long as the next two, second a little 

 longer than the third, both elongate, fourth shorter, club rather small. Pro- 

 thorax one-third wider than long, the sides broadly, evenly arcuate, becoming 

 parallel toward base, convergent and deeply constricted near the apex, the 

 latter nearly two-thirds as wide as the base ; punctures very coarse, deep, 

 moderately dense. Elytra fully one-third wider than the prothorax, scarcely 

 more than twice as long, one-fourth longer than wide, subparallel, obtuse at 

 apex, with a small cuspiform sutural notch ; striae very coarse, crossed trans- 

 versely at the bottom by rather distant ridges. Hind femora not at all promi- 

 nent beneath. Length 2.0-2.4 mm. ; width 0.9-1.2 mm.

 The large series before me indicates but slight variability, and 

 the characters given above will readily serve to identify this species,
