the elytra being only just visibly shorter and broader, and the 

 head about three-fifths as wide as the prothorax. The fifth ven- 

 tral in the male is transversely truncate and short as usual. Six 

 specimens. 



This species may be readily distinguished from hystrix by its 

 more elongate and depressed form and feebly rounded sides of 

 the prothorax. 



66. T. tectus n. sp. — Oblong, rather stout, strongly convex, polished, black, 

 Avithout metalliclustre ; legs piceous-black ; antennre black, piceous toward base; 

 pubescence long, coarse, cinereous, subdecuml)ent, intermixed throughout the 

 upper surface with moderately al)undant very coarse and erect black setae. 

 Head three-fifths as wide as the prothorax, smooth and polished, rather finely 

 but strongly and somewhat closely perforato-punctate, the impressions almost 

 obsolete; epistoma large, transverse; labrum large and long, broadly rounded, 

 with a transverse series of stiff set;« behind the middle; eyes rather large but 

 not prominent; antennse barely as long as the prothorax, feebly incrassate to- 

 ward tip, the penultimate joints distinctly transverse. Pi-oilwrax three-fifths 

 ^-ider than long, parallel, the sides evenly and feebly arcuate throughout ; all 

 the angles slightly obtuse and ])lunt though distiuguisha])le ; apex and base 

 equal, feebly and equally arcuate; disk finely but strongly, rather sparsely 

 perforato-punctate, not at all rugose toward the sides. Elytra one-half longer 

 than wide, not evidently wider than the prothorax, parallel and straight at 

 the sides, the apex evenly and almost semi-circularly rounded; disk finely but 

 sti'ongly, closely punctate, the interspaces smooth. Abdomen very densely 

 clothed with cinereous pubescence, which is rather long and coarse. Length 

 4.0 mm.; width 1.65 mm. 



California. 



The single specimen is a female without further record of 

 locality'. The species is A'ery distinct because of its rather large 

 size and very long shagg}- coat of pale cinereous hairs, in addi- 

 tion to the erect setre.

Oblong-oval, moderately convex, polished and smooth through- 

 out the upper surface, black, the legs and antennae black, the 

 funicle of the latter slighth' picescent toward base; pubescence 

 long, coarse, cinereous and rather dense, subdecurabent, inter-

 mostly black in color. Head scarcely three-fifths as wide as 

 the prothorax, fineh' but strongly, sparsely punctate, the frontal
