TENEBRIONID.E 145 



slender, convex, deep black, opaque throughout, the abdomen shin- 

 ing; head feebly impressed, coarsely punctate, densely so anteriorly, 

 sparsely posteriorly, the interspaces with fine scattered punctures: 

 antenna 3 much shorter than the prothorax, slender; prothorax 

 about one-half wider than long, widest at the middle, three-fourths 

 as wide as the elytra, the sides strongly, evenly rounded, the apex 

 very moderately sinuate, with slightly advanced but rather blunt 

 angles, barely narrower than the base, the latter oblique and broadly, 

 feebly sinuate to the obtuse angles at the sides; surface opaque, 

 moderately convex, with moderately large deep and very dense sub- 

 asperate punctures, the sides narrowly concavo-explanate, more 

 coarsely and densely punctato-rugose, the edges moderately thick; 

 elytra fully three-fourths longer than wide, evenly oval, with rather 

 strongly arcuate sides, gradually declivous and narrowed behind, the 

 apical lobe large but not strongly denned; basal margin with a small 

 prominent lateral tooth; surface densely opaque and with fine and 

 rather shallow, muricate, very close-set punctures, the side margin 

 acute and distinctly cariniform, though but little elevated, to apical 

 fifth; abdomen with small but coarse and deep anastomosing creases, 

 finely, not densely punctate, more strongly punctate posteriorly; 

 legs rather short, the femora bristling with short sparse fulvous setae. 

 Length (9) 17.0 mm.; width 7.5 mm. California (Kern Co.). 



spurcans n. sp. 



Elytra with very strongly elevated narrow even costae and strongly 

 cariniform margins, the suture also strongly elevated 2 



Elytra with feebly elevated or vestigial though fine costae, as well as 

 sutural and lateral margins $ 



2 Lateral edges of the prothorax thin. Form elongate, black, sub- 

 opaque; prothorax convex, shorter than wide, the sides strongly, 

 more or less evenly rounded, depresso-marginate and rugose, the 

 posterior angles very obtuse; surface evenly, rather densely punctate; 

 elytra [cf ] narrower than the prothorax, the suture, margin and three 

 costae on each strongly elevated, the first and second uniting at about 

 apical sixth, the third beginning at the margin at about basal fourth, 

 ending opposite the confluence of the other two costae. Length 

 15.7-20.0 mm. California (Tejon). [Pelecyphorus costipennis Lee.; 

 Asida lecontei Horn] costipennis Lee. 



Lateral edges of the prothorax thick and upturned; form more ventricose; 

 elytral punctures closer and more granulose. Form somewhat stout 

 ( 9 ), convex, deep black; head opaque, deeply, transversely impressed, 

 with a rectilinear impression also along the median line and ending 

 between the eyes, the punctures strong but not very coarse or close; 

 prothorax two-fifths or more wider than long, relatively small, barely 

 two-thirds as wide as the elytra, the apex narrower than the base, 

 moderately sinuate, with the angles rather blunt, the sides evenly 

 rounding and subparallel from apex to base, widest at the middle; 

 surface even, broadly and moderately convex, feebly bi-impressed 

 medially at base, strongly alutaceous, strongly, closely punctate, 

 rather abruptly and not widely concave, reflexed and more coarsely,
