Montana. The type specimen, which appears to be a male, 

 agrees so thoroughly with the description of Say, that there can 

 be little doubt of its representing the true aratus. It is unfortu- 

 nate, however, that there should be two names in the same genus 

 and within the same faunal limits which are mutually so similar. 

 The term ''olivaceous," applied by Say to the color of aratus, 

 might have wide limits of meaning. 



8 T. semisquamosus Lee. — Proc. Am. Phil. Soc, XV, p. 217. 



Narrowly oblong-oval, rather convex, piceous, the legs, antennae 

 and tip of beak rufescent ; vestiture complex, consisting of narrow 

 elongate fulvous squamules on the pronotum, which become broad 

 white scales in the middle and at each side but only near the base, 

 anteriorly there are also some widely scattered large brown scales ; 

 on the elytra the intervals are clothed throughout with stout re- 

 curved and subrecumbent brown setae, among which there are very 

 sparsely strewn large dark gray -brown scales, the latter dense im- 

 bricated and reddish along the sutural interval ; on the under surface 

 the scales are whitish, elongate-oval and dense throughout. Beak 

 in the male short, thick, not as long as the prothorax, feebly taper- 

 ing from base to apex, densely squamulose except near the tip, the 

 antennae inserted at apical two-fifths, the basal joint of the funicle 

 very stout, not as long as the next three, second but slightly longer 

 than the third, narrow at base, three to seven subequal, moniliform; 

 club abrupt, oblong-oval. Prothorax very nearly as long as wide, 

 the apex three-fifths as wide as the base, finely and feebly con- 

 stricted. Elytra at base scarcely one-third wider than the protho- 

 rax, three times as long, the sides straight and parallel in basal two- 

 thirds ; striae fine, impressed, with the white squamules distinct. 

 Length 2.5 mm.; width 1.0 mm. 



California. This species can be easily identified by the narrow 

 form, sparse scales of the elytra except along the suture, and absence 

 of erect ventral hairs. The large scales of the upper surface are, as 

 usual, granulose in structure and not strigate. 



9 T. lamellOSUS n. sp. — Rather broadly oblong-oval, convex, piceous, 

 the tibiae, antennae and tip of beak rufescent ; vestiture dense and varied, 

 consisting on the pronotum of long narrow fulvous strigose squamules, gradu- 

 ally intermixed toward the sides and almost replaced by large whitish scales, 

 also narrowly along the middle, more broadly toward base ; on the elytra the 

 non-strigose scales are very large, broad, ogival, pearly white in color, dense
