REVISION OF TENEBRIONID SUBFAjNIILY CONIONTIN^?^ 85 



three-fifths as wide as the base, deeply and broadly parabolic, the 

 angles slightly obtuse and not thickened ; surface similarly punc- 

 tured and with the side margins almost similarly concave and 

 reflexed ; elytra almost similar but with the apical angles not so 

 individually rounded ; prosternum with well separated strong 

 punctures and having a densely, rugosely punctured area at the 

 base of the process; abdomen strongly, more closely punctured 

 and rugose medially. Length 16.0 mm. ; width 7.S mm. Near 

 Monterey gravis n. sp. 



7 — Form oblong, twice as long as wide, convex, shining, scarcely at 



all alutaceous anteriorly, deep black, glabrous ; head rather finely 

 but perforately, not densely punctate, not at all impressed an- 

 teriorly, the anterior canthus rounded, slightly more prominent than 

 the posterior; antennae slender, joints three to seven much elon- 

 gated, the eighth thicker but much longer than wide, the ninth a little 

 longer than wide ; prothorax nearly three-fifths wider than long, 

 the sides parallel and straight in basal half, then gradually rounded 

 and strongly convergent to the broadly, circularly emarginate apex, 

 which is fully two-thirds as wide as the base, the angles right 

 and bluntly rounded ; surface rather finely, sparsely punctured, 

 becoming rather coarsely, more closely and conspicuously so 

 laterally, the side margins concave and reflexed; elytra barely as 

 wide as the prothorax, scarcely one-half longer than wide, par- 

 allel, obtuse at tip, the sides concave and reflexed, the surface 

 coarsely and strongly rugose but polished, less rugose toward 

 base as usual ; prosternum rather finely but strongly, not very 

 closely punctate, the process very wide, obtuse, transversely con- 

 vex, less coarsely margined at tip ; abdomen strongly but not 

 very coarsely, rather sparsely punctured, very obsoletely rugulose, 

 alutaceous in lustre. Length 15.0 mm. ; width 7.3 mm. 



rugosa n. sp. 



8 — Form oblong, convex, twice as long as wide, deep black, slightly 



alutaceous throughout ; head strongly, rather closely punctured, 

 finelv and sparsely basally, the apical sinus rather shallow, broadly 

 rounded, the surface obsoletely impressed behind each apical 

 lobe; anterior canthus narrowly rounded, as prominent as the 

 posterior; prothorax fully one-half wider than long, formed as in 

 rugosa^ the punctures much more minute, almost invisible and 

 sparse medially, rather sparse and not coarse though distinct 

 laterally, the margin much more narrowly and feebly reflexed, 

 the fine bead strongly elevated ; elytra rather less than one-half 

 longer than wide, equal in width to the jirothorax, parallel, ob- 

 tuse at tip, the surface alutaceous, not rugose but with about six 

 very feeble and broadly tumescent lines on each, coming together 

 in some broad rugosity at apex; the punctures shallow and very 

 feeble suturally, deeper, closer and more distinct laterally, the 

 margin deeply concave and narrowly reflexed, each puncture with 

 a very minute silvery seta not projecting beyond its limits; pro- 

 sternum rather finely, strongly and sparsely punctate ; abdomen
