REVISION OF TENEBRIONID SUBFAMILY CONIONTIN^ 89 



feebly undulato-rugose, the punctures fine and remote, more dis- 

 tinct laterally, the fulvescent hairs not at all conspicuous; pro- 

 sternum more strongly, rather closely punctate, the abdomen 

 smooth, moderately sparsely punctulate. Length 13. S mm. ; width 

 6.5 mm. Pomona Mts luctuosa n. sp. 



Form a little shorter, broader and more convex, dull in lustre through- 

 out above, more strongly punctured than in any other species 

 of the group, deep black; head rather coarsely, deeply, not very 

 closely and rather unevenly punctate, not impressed, the anterior 

 canthus rather narrowly rounded and somewhat more prominent 

 than the posterior; prothorax a little wider than the base of the 

 elytra, transverse, fully two-thirds wider than long, the sides sub- 

 parallel and feebly arcuate, gradually more arcuate and converg- 

 ing anteriorly, the apex broadly sinuate and nearly three-fourths 

 as wide as the base, the angles right and blunt ; surface finely but 

 strongly, rather sparsely punctate, gradually coarsely, somewhat 

 closely and very conspicuously so laterally, each puncture with a 

 small hair, the margin strongly beaded, the attendant channel 

 deep also at apex laterally; scutellum moderate, not very trans- 

 verse, triangular; elytra not quite one-half longer than wide, ob- 

 tusely angulate at tip, the sides parallel and very feebly arcuate, 

 finely reflexed ; surface of each with four feebly tumescent ridges, 

 with intermediate ridges also, though very obsolete, the four ridges 

 very strong on the apical declivity, the punctures sparse, strong 

 and not very fine medially, becoming very coarse, closer and con- 

 spicuous laterally, the fulvous hairs distinct ; prosternum rather 

 coarsely and closely punctate, the abdomen polished, minutely, 

 sparsely punctulate. Length 13.0 mm.; width 6.7 mm. San 

 Bernardino Mts costulata n. sp. 



Form stout, not more than twice as long as wide, not pubescent, con- 

 vex, parallel, the integuments above subopaque, the pronotum 

 and elytra very densely, rather coarsely and aciculately punctate, 

 the elytra obscurely tricostate, with the intervals obsoletely reticu- 

 late ; [abdomen minutely, sparsely punctulate]. Length 15.5 

 mm. Fort Tejon robusta Horn 



Form oblong, moderately elongate, with the sides feebly arcuate, rather 

 strongly convex, very highly polished, smooth, the vestiture mi- 

 nute, fulvous in color ; head rather coarsely and densely punctured, 

 the sides as prominent as the posterior canthus of the eyes, the 

 antennae slender ; prothorax one-half wider than long, the apex 

 nearly two-thirds as wide as the base, the angles rather broadly 

 rounded; base transverse, very feebly sinuate laterally, the angles 

 slightly rounded and not prominent, the sides strongly arcuate 

 anteriorly, feebly so posteriorly ; surface very finely punctured, 

 the punctures becoming denser at the sides, the bead strong ; ely- 

 tra at least twice as long as the prothorax, the punctures fine 

 though larger than those of the pronotum, rather sparse, the sides
