REVISION OF TENEBRIONID SUBFAMILY CONIONTIN^E 77 



obtuse behind, the margin of the prothorax and the legs ciliate 

 with long yellowish hairs; head sparsely, finely punctate, the 

 clypeus deeply and broadly emarginate, with a moderately deep 

 incisure at each side, the entire front margin reflexed ; prothorax 

 more than twice as wide as long, much narrowed in front, the sides 

 arcuate, the side margin explanate, the hind angles slightly pro- 

 longed but not acutely ; surface smooth, with a few fine piliferous 

 punctures near the sides; elytra with minute, sparse, submuricate 

 granules, each with a short hair, the interspaces very minutely 

 alutaceous ; epipleuras gradually wider from apex to base, sparsely 

 punctate and ciliate ; prosternum sparsely punctate, ciliate with 

 yellow hairs, the tip of the process narrowly oval ; abdomen very 

 sparsely, finely punctate ; legs ciliate with moderately long yel- 

 lowish hairs. Length 11.5 mm. Lower California (Big Canyon, 

 Tantilles Mts.) ciliata Horn 



Form more oblong than in muricata, very much smaller in size and 

 more pointed behind, the sides arcuately converging from about 

 the middle of the elytra, similarly very convex, black; head simi- 

 larly sinuate laterally, feebly emarginate and apically reflexed, 

 the surface subopaque, finely, sparsely and muricately punctate, 

 each puncture with a small decumbent yellow hair, the punctures 

 broadly wanting along the middle, narrowly so anteriorly; pro- 

 thorax less transverse, barely two and one-half times as wide as 

 the median length, evenly though much less strongly narrowed 

 from base to apex than in any other species, the sides evenly 

 and feebly arcuate, finely beaded, similarly but rather less broadly 

 explanate, the apex more circularly emarginate, the angles simi- 

 larly bluntly rounded, the basal produced, slightly less than right 

 and not blunt ; surface alutaceous, impunctate except near the 

 sides and narrowly along the basal margin, where the punctures 

 are rather sparse but distinct and muricate, each bearing a small 

 yellow hair; elytra as long as wide with rounded sides, before 

 the middle rather wider than the prothorax, convex, densely 

 opaque though even, not very coarsely, rather sparsely punctate, 

 the punctures but feebly muricate, each bearing a small and very 

 coarse, decumbent fulvous hair; under surface more glabrous 

 than usual, shining, the epipleurae finely, sparsely punctate, sub- 

 glabrous and polished ; tarsi very slender ; antenna only moder- 

 ately developed as usual in this genus. Length 7.6 mm. ; width 

 4.6 mm. Texas (Sta. Rosa), H. F. Wickham...puberula Lee. 



The species defined above, by compilation of the descriptions 

 of LeConte and Horn, under the name dilatata, appears to have 

 been wrongfully reduced to synonymy, the densely punctulate 

 epipleurae and more or less confluent granules of the elytra 

 amply distinguishing it from muricata, aside from its radically 

 different habitat. Puberula is identified from description only, 

 but the specimen here described is probably typical ; it repre-
