 near the town. It is yery distinct in its longer antennae and 

 relatively smaller prothorax. 



55 T. blediiiiu§ Lee. — Trans. Am. Ent. See, VI. p. 244. -Rather 

 ■slender, moderately convex, black; legs piceous, knees, tips of tibiae 

 and tarsi pale; antennae piceous; pubescence extremely short, rather 

 dense but not very conspicuous; integuments slightly shining. Head 

 slightly narrower than the prothorax, scarcely as long as wide, very 

 minutely and densely punctate; prominences rather large and strong; 

 «yes moderate, very convex, prominent, very coarsely faceted; an- 

 tennae rather slender, short, not as long as the head and prothorax, 

 ^ery feebly incrassate; second joint as long as the next two together 

 and rather more robust, third one-half longer than the fourth, the lat- 

 ter slightly wider than long, tenth rather strongly transverse. Pro- 

 thorax about one-fifth wider than long; sides in the apical half almost 

 parallel, evenly and feebly arcuate, moderately convergent and feebly 

 sinuate in the basal half; base broadly arcuate, fully four-fifths as wide 

 as the disk; apex transversely, very feebly arcuate; apical angles 

 nearly right, narrowly rounded, basal broadly rounded; disk broadly, 

 evenly convex, not impressed but with a rather wide, irapunctate, me- 

 dian line, which appears to be sometimes slightly tumid; punctures 

 minute and dense. Elytra slightly longer than wide, scarcely one- 

 third wider and fully three-fifths longer than the prothorax, rather dis- 

 tinctly impressed near the suture at the base, finely, rather densely 

 punctate; punctures rather coarser than those of the pronotum and 

 -about twice as distant. Abdomen very distinctly narrower than the 

 prothorax; sides nearly parallel, straight; surface finely reticulate, 

 minutely and densely punctate, rather shining. Legs very short, 

 slender. Length 2.2 mm. 



California (San Diego 2). 



A small slender species, somewhat resembling confinis, but 

 differing in its longer elytra and in the shape of the prothorax. 



56 T, fallax n. sp. — Somewhat slender, convex, piceous-black ; 

 legs brownish-flavate; antennae fuscous, piceous toward apex; pubes- 

 cence short, subrecumbent, very dense and rather conspicuous, espe- 

 cially on the anterior portions; integuments rather dull. iJead slightly 

 narrower than the prothorax, feebly convex, minutely, densely punc- 

 tate and subgranulose; prominences rather large, slightly elongate and 

 strong ; eyes large, strongly convex and prominent, very coarsely 

 faceted; antennae short and rather robust, much shorter than the head 

 and prothorax; joints two to four decreasing very rapidly in length,
