T. gracilicornis n. sp. — Moderately slender and fusiform, feebly con- 

 vex, black ; legs and antennae throughout piceous-black ; integuments alutace- 

 ous. Head small, nearly as long as wide ; sides parallel in basal half ; surface 

 very feebly convex, finely, densely punctate ; tuberculations moderate, rather 

 distinctly elevated ; eyes rather large and convex, very coarsely faceted ; sides 

 behind them very short, about one-third as long and obtusely, narrowly 

 rounded ; antennse very slender, much longer than the head and prothorax, 

 extremely feebly incrassate, all the joints longer than wide, second shorter 

 than the next two, fourth and fifth subequal, longer than the sixth and shorter 

 than the third, ninth longer than the tenth, the latter but slightly longer than 

 wide, eleventh cylindrical, abruptly pointed, two and one-half times as long as 

 wide. Prothorax rather more than one-fourth wider than the head, one-sixth 

 wider than long ; base scarcely perceptibly narrower than the apex, both feebly 

 arcuate ; sides nearly parallel, feebly arcuate ; apical angles narrowly but 

 distinctly, basal broadly, rounded ; disk evenly and rather distinctly convex, 

 without trace of impressions, very minutely, feebly punctate ; punctures not 

 distinctly definable. Elytra one-third wider and nearly one-half longer than 

 the prothorax, quadrate, depressed ; sides parallel and nearly straight ; sur- 

 face extremely minutely, densely jjunctate and pubescent. Abdomen gradually 

 narrowed from base to apex, slightly narrower than the elytra ; segments 

 rather long ; border moderate, not very deep ; surface dull, finely and strongly 

 punctato-reticulate, the reticulations small and slightly transverse. Length 

 1.5 mm. 



California (Sonoma, San Mateo and Santa Clara Cos. 8). 



This species seems to vary slightly in the relative proportion of 

 its parts, but I can perceive no well-defined limits of a specific 

 nature. It is very distinct from paUidus in its larger size, black 

 color, smaller head, finer, stronger abdominal sculpture, and several 

 other characters. 



T. crassicorilis n. sp. — Extremely slender, linear, subdepressed, pale 

 brownish-fiavate ; legs and antennae very pale fiavate ; integuments shining, 

 the pubescence moderate in length although somewhat dense. Head nearly 

 as long as wide, feebly, evenly convex above, rather coarsely and sparsely 

 punctate, the interspaces fully twice as wide as the punctures, polished, the 

 epistoma on a slightly lower plane than the front, the suture short, strongly 

 arcuate and very distinct ; tuberculations small Vjut rather prominent ; eyes 

 moderate ; tempora parallel, abruptly rectangular behind, the head being 

 transversely truncate at base ; antennae fully as long as the head and pro- 

 thorax, robust, distinctly incrassate, the second joint very short, scarcely one- 

 third longer than wide and slightly shorter than the next two together, third 

 transversely oval, fourth and sixth rather wider than the third, very strongly 

 transverse, about equal in width to the fifth but rather shorter, the latter 

 nearly twice as wide as long, outer joints very strongly transverse, twice as 

 wide as long, the eleventh ovoidal, pointed, one-third longer than wide. Pro- 

 thorax equal in width to the head and very slightly shorter, two-fifths wider
