404 Coleopterological Notices, V. 



not at all explanate even near the basal angles. Elytra in the male two and 

 one-half times as long as the prothorax, in the female nearly three times as 

 long, longer than wide, near the apex almost twice as wide as the prothorax ; 

 sides nearly straight, feebly divergent, external apical angles very broadly 

 rounded and oblique ; punctures fine but strong, dense. Scutellum more 

 finely and extremely densely punctate. Abdomen very short behind the elytra, 

 extremely minutely, densely punctulate. Legs slender. Length 6.0-6.3 mm. ; 

 width 2.3-2.6 mm. 



California (Siskiyou Co.). 



The male has the intermediate tibiae very feebly swollen, slightly 

 constricted in apical fourth, the constricted part glabrous; in the 

 female the same tibiae are more slender and have the glabrous ter- 

 minal part scarcely at all constricted but occupying almost one-third 

 of the total length. Three specimens. 



T. brevipeilllis n. sp. — Strongly shining, castaneous, the legs and 

 coxae paler, rufous ; pubescence fine, moderate in length, abundant and uni- 

 form. Head finely, densely punctate, nearly as in rujitarsis, the fourth palpal 

 joint fully twice as long as the third and one-half longer than the second ; 

 antennae very slender, filiform, rufous, three-fifths as long as the body, the 

 joints very elongate, scarcely perceptibly obconical, the tenth very nearly 

 three times as long as wide. Prothorax one-half wider than long and one-half 

 "wider than the head, widest and obtusely subangulate at the sides just before 

 the middle ; sides thence to the base convergent and feebly sinuate, becoming 

 more sinuate only extremely near the basal angles which are right and not 

 blunt, to the apex feebly convergent and slightly arcuate ; apex feebly bisinu- 

 ate ; disk finely, closely punctate, not at all impressed on the disk near the 

 base, the lateral impression large but only moderately deep ; sides broadly, 

 feebly reflexed from the hind angles past the fovea to apical fourth. Elytra 

 not quite as long as wide, four fifths longer than the prothorax, and, near the 

 apex, two-fifths wider than the latter ; sides nearly straight and divergent 

 from the exposed but rounded humeri nearly to the apex; disk strongly, 

 moderately densely punctate. Abdomen short, very minutely, densely punc- 

 tulate. Legs very long and slender. Length 6.5 mm. ; width 2.6 mm. 



Wyoming. 



The single male before me has th'e intermediate tibiae slender and 

 almost evenly cylindrical, with the glabrous apical part extremely 

 short and not in the least constricted, differing greatly in this re- 

 spect from rujitarsis. 



T. castanea n. sp. — Less broad, strongly shining ; castaneous ; legs and 

 antennae rufo-testaceous ; pubescence fine, dense, uniform and inclined. Head 

 finely punctate, sparsely so toward the middle, otherwise as in rvjitarsis but 

 with rather longer and more angulate tempora ; antennae filiform, three-fifths
