Coleopterological Notices, VI. 51 T 



Although to be phiced near hrevipilosus in a natural scheme of 

 classification, this species is not closely allied ; it is smaller, with 

 the pale setre of the elytra coarser and ver3' much more alnindant, 

 and the lobiform base of the prothorax is more pronounced. The 

 single male has the fifth venti-al much longer than the fourth and 

 only moderatel}' broadly sinuato-truncate at apex.

Elongate, parallel, strongly- convex, polished, black with a 

 gra3nsh-ffineous lustre ; legs piceous-black, the tibiae and tarsi 

 rufescent; antennje piceous-black; pubescence rather long and 

 moderately coarse, subdecumbent, pale fulvo-cinereous and some- 

 what dense, with numerous erect seti« which are long bristling 

 and in great part black anteriorly but short and mostly pale on 

 the elytra, where they are intermixed with a few very long black 

 hairs toward the sides ; marginal fringe of the elytra moderately' 

 long, fine and in great part ashy. Head fully two-thirds as Avide 

 as the prothorax, smooth, finely and sparsely punctate, the 

 epistoma extremely short ; labrum short and broadl}' rounded ; 

 antenna? scarcely- longer than the prothorax, not very stout, the 

 penultimate joints but slightly asymmetric and moderately- trans- 

 verse, fifth just visibly dilated. Prothorax two-thirds wider than 

 long, the sides parallel, almost evenly and moderately arcuate ; 

 angles somewhat distinct though blunt ; disk minutely, sparsely 

 punctate, not rugose laterally. Elytra three-fifths longer than 

 wide, only slightly wider than the prothorax, parallel, rather 

 acutely rounded behind ; humeri only moderately prominent ; 

 punctures fine but strong and relatively not very close-set. Ab- 

 domen and legs densely clothed with short coarse fulvo-cinereous 

 pubescence. Length 3.3 mm.; width 1.3 mm. 



Middle California. The female here described is the only rep- 

 resentative which I have seen. This species is not liable to be 

 confounded with any other known to me. 



Another female, from a diflerent locality in California, seems to 

 represent a very closely allied species with a shorter and smaller 

 prothorax and a less abbreviated epistoma, the latter having a 

 much broader impunctate margin.
