antennse inserted a little behind the middle ; antennae slender, the basal joint 

 of the fnnicle about as long as the next two, second and third both slightly 

 elongate, club moderate. Prothorux small, one-third wider than long, the sides 

 rounded, convergent and scarcely perceptibly constricted anteriorly, becoming 

 parallel in basal half; apex transversely truncate, two-thirds as wide as the 

 base. Elytra fully one-third wider than the prothorax, scarcely three times 

 as long, barely one-fourth longer than wide ; sides parallel in basal half or 

 slightly more. Posterior femora rather slender, not at all toothed. Length 

 1.6-1.75 mm. ; width 0.8-0.9 mm.

The elytra have a very small sutural notch, but are not individu- 

 ally broadly rounded as they are in Sibinia. This peculiar type 

 is well represented in Brazil. Four specimens. 



14 T. mica n. sp. — Oblong-oval, rather convex, rufo-piceous throughout ; 

 vestiture moderately dense, generally whitish, pale brown on the disk of the 

 pronotum, consisting throughout, on the upper surface, of parallel but rather 

 broad strigose recumbent scales, rather dense on tlie pronotum, becoming 

 broader and whiter on the flanks but not different in structure and without 

 trace of intermixed setae or broad rounded scales ; on the elytra similar, re- 

 cumbent and uniform in structure throughout, but somewhat denser toward 

 the suture ; on the under surface larger, elongate-oval, denser. Head squani- 

 ose, the transverse line fine ; eyes wider than long ; beak in the male stout, 

 densely squamulose except at the tip, feebly arcuate, gradually and not very 

 rapidly tapering, scarcely longer than the prothorax, with the antennae in- 

 serted at apical third ; antennae rather short, the first funicular joint very 

 robust, strongly narrowed at base, as long as the next two, second one-half 

 longer tlian the third, the latter barely longer than wide. Prothorax small, 

 nearly one-third wider than long, the sides subparallel and almost straight in 

 basal half, then rounded, convergent and deeply constricted to the apex, the 

 latter broadly arcuate, two-thirds as wide as the base ; punctures dense. Elytra 

 one-third wider than the prothorax, two and one-half times as long, one-fourth 

 longer than wide, obtuse at apex, becoming parallel in about basal half; striae 

 somewhat coarse. Legs rather slender, the posterior femora not prominent 

 beneath. Length 1.5 mm. ; width 0.7 mm. 



Arizona. 



This species is not closely allied to any other, but is represented 

 by a singe rather imperfect male example. It is easily distinguish- 

 able by the uniform structure of the parallel strigose scales of the 

 upper surface, and by the absence of erect bristles. 



15 T. setosus Lee— Proc. Am. Phil. Soc, XV, p. 218. 



Oblong-oval, moderately convex, more or less pale piceo-rufous ; 

 vestiture uneven, consisting of small subrecumbent robust setas.
