T. laticeps n- sp. — Form slender; body rather dark piceoits - brown 

 thriiugliont; legs slightly paler; auteuuiB piceons-black; iutegainf-uts highly 

 polished; pubescence extremely fine end rather spars'^, closely recumbent. 

 Head distinctly wider than long, broadly and squarely truncate at base; sides 

 behind the eyes parallel and slightly arcuate, basal angles slightly rounded;, 

 front and occiput transversely, equally and moderately convex, excessively, 

 minutely and very spars> ly punctate; eyes rather small, not at all prominent;. 

 antenn.'B as long as the head and pronotiim together, first three joints de- 

 creasing uniformly and rather rapidlj' in le'gth, joints four to ten equal iu 

 length, the former slightly longer than wide, the latter slightly wider than 

 long, eleventh as long as the two preceding together, abruptly compressed 

 near the tip. Prothorax widest at about one-third its length from the apirX 

 where it is scarcely percej)tibly wider than the head and sliglitly wider than 

 long; sides strongly convergent and arcuate to the apex, and very feebly con- 

 vergent and rather strongly arcuate to the base; the latter broadly, evenly 

 and strongly arcuate, very slightly narrower than the disk and much wider 

 than the apex; disk rather strongly and tra'isversely convex, extremely 

 feebly and transversely impressed in the middle just before the base, ex- 

 tremely, minutely, evenly and rather sparsely punctate. Elytra at base 

 about one-fourth wider than the prothorax; sides nearly parallel, evenly and 

 distinctly arcuate; together broadly truncate and trisinuate at apex; disk 

 depressed, narrowly impressed on the suture toward the scutellum, quadrate,, 

 nearly one-third longer than the pronotum, Hnely, nearly evenly and sparsely 

 punctate ; punctures larger thun those of the pronotum, feeble and sub- 

 asperate, forming very broken series, giving a slightly imbricated apiDcarance 

 in certain positions. Abdomen at base slightly narrower than the elytra;, 

 sides parallel and straight; first three segments impressed at base, very 

 slightly more coarsely punctate in the impressed areas, elsewhere finely, 

 rather densely and asperately punctate; middle longitudinal caringe obsolete. 

 Legs moderate in length, very slender; posterior tarsi very slender, first 

 joint distinctly longer than the next two together, nearly as long as the last 

 three. Length l.'J mm. 



California (Paraiso Springs, Monterey Co., 1). 



The type is a female, the sixth ventral segment being 

 broadly and very evenly rounded behind. It is easily dis- 

 tinguished by its small size, pale color and very elongated 

 basal joint of the posterior tarsi. 



T. faceta ^- sp. — Very slender; body piceous-black, antennae same, two 

 basal joints paler; legs piceous, extremities of the femora and tibiae paler, 

 tarsi testaceous; integuments polished; pubescence extremely fine, rather 

 dense but not conspicuous except on the abdomen where it is much coarser. 

 Head as long as wide; sides behind the eyes very moderately convergent ani
