strongly, densely granulose. Abdomen very short, strongly convergent toward 

 apex, slightly narrower than the elytra ; border rather wide and shallow ; sur- 

 face more coarsely and sparsely punctato-reticulate, the sixth segment appa- 

 rently with a fine coriaceous margin throughout the width. Length 0.9 mm. 



California,, Cab. LcConte. 



A very distinct species, easily distinguishable from any other of 

 this section by its more robust form, unimpressed jjronotum, broadly 

 emarginate apex of the prothorax, the head, i)rothorax and elytra 

 increasing in width in an almost uniform ratio, by the distinctly 

 arcuate sides of the elytra, the longer, more aberrant antennce, and 

 many other characters. The measurements of length given by 

 LeConte in his descriptions of the species of this genus are 

 decidedl}'^ too small. 



T. soiioiuae n. sp. — Rather slender, moderately depressed, piceous-Uack 

 throughout the body, legs and antennae, the elyti-a with a feeble castaneous 

 tinge ; integuments rather' dull. Ilmd fully as long as wide, feebly, evenly 

 convex, very finely, feebly and densely punctate ; antenna! tuberculations very 

 feeble ; eyes rather large, feebly convex, very coarsely faceted, the tempera 

 scarcely as prominent and about two-thirds as long, broadly rounded ; antennae 

 rather robust, distinctly clavate, scarcely longer than the head and prothorax, 

 second joint rather more than twice as long as wide and very slightly shorter 

 than the next two combined, third distinctly longer than the fourth, the latter 

 fully as long as wide, shorter than the fifth and subequal to the sixth, eleventh 

 ovoidal, pointed, two-thirds longer than wide. Protliorax slightly but distinctly 

 wider than the head, nearly three-fourths wider than long ; sides parallel, 

 feebly arcuate, the basal angles obsolete, very broadly rounded into the base 

 which is broadly feebly arcuate ; apex broadly, very feebly emarginate, the 

 apical angles slightly advanced and very narrowly rounded ; disk not at all 

 imx)ressed, feebly convex, very minutely and densely punctate tjiroughout. 

 Scutellum very small, equilatero- triangular. Elytra parallel, one-third wider 

 and four-fifths longer than the prothorax ; disk nearly flat, strongly imjjressed 

 at the scntellum, extremely minutely, densely punctate ; pubescence exces- 

 sively fine, short and dense, the longer erect hairs sparsely distributed over 

 the surface. Abdomen very slightly narrower than the elytra, rather short, 

 slightly narrowed toward apex ; border narrow and deep ; surface more coarsely 

 and sparsely punctate, also coarsely reticulate, and a little more shining than 

 the otlier portions, the sixth segment distinctly shining. Legs rather short 

 and robust. Length 1.2 mm. 



California (Duncan's Mills, Sonoma Co. 2). 



May be distinguished from pygmaeus by its larger size, longer, 

 relatively narrower prothorax, with the apical angles more advanced, 

 and by the entire absence of any distinct pronotal impressions. 

 The punctuation is slightly finer and denser than in that species.
