thorax, feebly but distinctly incrassate toward apex, the penultimate joints 

 rather strongly transverse. Profhontx nearly three-fourths wider than long, 

 the sides somewhat strongly rounded and suljprominent at basal two-fifths, 

 thence feebly convergent and slightly arcuate to the apex and more strongly 

 convergent and very broadly rounded into the base, which is a little narrower 

 than the apex and su1)truncate: apex rectilinear ly truncate, with the angles ob- 

 tuse and blunt; basal angles obliterated; disk finely, sparsely punctate, 

 coarsely reto-rugose toward the sides. Elytra long, fully three-fourths longer 

 than wide, slightly wider than the prothorax, parallel, evenly and not broadly 

 rounded at apex, the disk somewhat coarsely, deeply and sparsely punctate, 

 feebly explanate near the external apices, the interspaces polished. Abdomen 

 and legs finely subcinereo-pubesceut. Length 3.2 mm.; width 1.25 mm. 



California (Sonoma Co.). 



The single female before me has the fifth ventral very broadly 

 rounded behind, and represents a species somewhat allied to sex- 

 ualis, hut with very much more elongate elytra and more obtusely 

 rounded abdominal apex.

Elongate-oval, strongly convex, polished, black, the elytra pi- 

 cescent ; apices of the abdominal segments pale and coriaceous ; 

 legs pale rufo-ferruginous throughout; antenna? pale piceo-testa- 

 ceous, the fuuicle still paler toward base ; pubescence rather long 

 and fine, cinereous-white and very sparse, intermingled with 

 numerous black seta?. Head nearly three-fourths as wide as the 

 prothorax, finely but strongly', not very sparsely perforato-punc- 

 tate, the impressions large and distinct ; epistoma with a wide 

 and pale coriaceous margin ; labrum large, transverse, broadly 

 rounded, black with a narrow pale apex; eyes somewhat promi- 

 nent ; antennje slender, much longer than the prothorax, serrate, 

 the tenth joint nearl}^ as long as wide, fifth but feebl}' dilated. 

 Prothorax rather long, about two-fifths wider than long, the sides 

 broadly arcuate, becoming gradually convergent anteriorly; basal 

 angles ver^- broadly rounded ; apex truncate, about as wide as 

 the base ; disk rather evenly- and deeply perforato-punctate, the 

 punctures sparse but closer laterally', the interspaces smooth 

 throughout. . Elytra long, two-thirds longer than wide, distinctly 

 wider than the prothorax and nearly three times as long, evenly 

 and not obtusely' rounded behind, the disk very coarsely, deeply 

 and not very closely punctate. Length 2.3-3.3 mm.; width 0.95- 

 1.25 mm.
