5. T. frateriius u. sp. — Elongate, parallel, feebly convex, black, some- 

 what shining, slightly reuescent ; legs bright nifo-ferruginous throughout ; 

 antennae piceous-black, the funicle testaceous toward base, the basal joint 

 black ; pubescence moderately long and close on the elytra, finer and sparser 

 anteriorly, cinereous and distinct ; marginal cilia very short on the prothorax, 

 twice as long on the elytra, even. Head three-fourths as wide as the pro- 

 thorax, feebly convex, rather finely but closely punctato-scabrous, the frontal 

 impressions feeble, separated by a large impunctate space ; epistoma short, 

 pale and coriaceous, the labrum long, parabolic ; ej-es large and moderately 

 prominent ; antennae rather stout, moderate in length, the fifth joint feebly 

 dilated, almost equilateral, the tenth somewhat transverse. Prothorax short 

 and transverse, fully two-thirds wider than long, the sides parallel, evenly 

 and extremely feebly arcuate from base to apex, the former broadly arcuate 

 throughout with obtuse and rounded angles, the apex evenly and rectilinearly 

 truncate throughout the entire width, the angles right and Avell marked, though 

 bhmt ; disk rather finely and sparsely punctate, coarsely reto-scabrous near 

 the sides. Elytra three-fourths longer than Avide, scarcely visibly wider than 

 the prothorax, parallel and perfectly straight at the sides, very obtusely 

 rounded at apex, the humeri moderately tumid ; punctures somewhat fine 

 and close. Abdomen finely, densely and subasperately punctulate, finely 

 cinereo-pubescent ; femora stout. Length 3.7 mm. ; width 1.3 mm. 



California (San Francisco). 



The description is drawn from the male, and in that sex the 

 fifth ventral is very short, unmodified on the disk but with the 

 apex broadly truncate and distinctly sinuate in the middle. I 

 have not seen the female. 



This species is allied to cylindricus, but differs in the ver3'- 

 feebly arcuate sides of the prothorax, with conspicuous though 

 not at all prominent apical angles, in the much longer and denser 

 elytral pubescence and red legs. One specimen.

Elongate, parallel, black, the legs and antennaj black through- 

 out ; pubescence cinereous, very short though somewhat coarse 

 and distinct, decumbent and sparse ; marginal fringe short. Head 

 nearly three-fourths as wide as the prothorax, punctato-scabrous; 

 eyes large and somewhat prominent ; epistoma pale and coriaceous ; 

 labrum broad, feebly arcuate at apex ; antennte rather slender, 

 longer than the prothorax, the fifth and seventh joints onl}' just 

 visibly dilated, the tenth slightly transverse. Prothorax two-
