incrassate, outer joints distinctly transverse; joints two to four decreas- 

 ing very rapidly in length, second nearly as long as the next two com- 

 bined, fourth very slightly longer than wide, feebly obconical; eyes 

 rather large, convex, prominent and coarsely faceted. Profhorax 

 widest just before the middle, where the sides are distinctly rounded and 

 obtusely subangulate, thence slightly convergent and evenly, distinctly 

 arcuate to the apex, slightly more strongly convergent and nearly 

 straight toward base; the latter broadly arcuate, fully three-fourths as 

 wide as the disk and much narrower than the apex; the latter feebly 

 arcuate; apical angles slightly obtuse, not distinctly rounded, basal 

 more broadly so; disk about one-fifth wider than long, broadly, evenly 

 convex, not at all impressed, finely and not densely punctate in the 

 middle, the punctures becoming excessively fine and obsolete near the 

 sides, where the surface is more strongly reticulate; median impunctate 

 line rather wide, abbreviated, not sensibly tumid. Elytra scarcely 

 perceptibly wider than long, one-fourth wider and one-third longer than 

 the prothorax, feebly impressed near the suture toward base, moderately 

 and sparsely punctate; punctures rather feeble, much larger than those 

 of the pronotum, and separated by fully twice their own diameters. 

 Abdomen slightly narrower than the elytra, parallel, shining; border 

 moderate, nearly straight; surface very obsoletely reticulate, minutely 

 and not very densely punctate. Legs slender. Length 2.0 mm.

63 T. in§olitus n. sp.— Slender, slightly convex, black; legs and 

 antennae piceous; pubescence very short, moderately dense; integu- 

 ments feebly shining, the head and pronotum dull. Head scarcely per- 

 ceptibly narrower than the prothorax, rather strongly convex, minutely, 

 strongly, and very densely granulose or deeply reticulate, the punctures 

 fine and not distinct; prominences very small, short; eyes moderately 

 prominent, moderately finely faceted; antennae short, somewhat robust, 

 scarcely as long as the head and prothorax; second joint robust, about 

 as long as the next two together, third distinctly longer than the 

 fourth, slightly longer than wide, the latter wider than long, outer 

 joints strongly transverse. Prothorax nearly two-fifths wider than 

 long, widest in the middle; sides thence feebly convergent and very 

 feebly arcuate to the apex, moderately convergent and nearly straight 

 to the base, which ihs tree-fourths as wide as the disk and much nar- 

 rower than the apex, the latter transversely truncate; apical angles 

 very slightly obtuse and scarcely perceptibly rounded; disk evenly, 

 feebly convex, minutely, strongly, and very densely granulose, dull; 

 punctures very dense and not distinctly defined; the usual two impres- 

 sions represented by the very feeblest traces, interrupted in the mid'
