REVISION OF TENEBR10NID SUBFAMILY CONIONTIN^E 93 



9 Elytral punctures with very evident small decumbent hairs. 



Body somewhat elongate, parallel, moderately convex, rather 

 dull and alutaceous in lustre, black with a pronounced piceous 

 tinge, the legs frequently rufescent, the antennae pale throughout 

 and slender ; head finely but strongly, rather sparsely punc- 

 tate, not impressed, the canthi about equally prominent; pro- 

 thorax nearly three-fifths wider than long, the sides broadly and 

 moderately arcuate and converging anteriorly, becoming very 

 feebly arcuate and but just visibly diverging thence to the base, 

 the apical angles very bluntly rounded ; punctures very minute 

 and sparse medially, becoming much larger, deep and distinct 

 though still well separated laterally, the marginal bead very fine ; 

 scutellum only moderate in size, broadly triangular; elytra 

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

 parallel, gradually parabolic at apex, virtually smooth though 

 more opaque than the pronotum, the punctures fine, rather sparse, 

 becoming more distinct laterally; prosternum rather strongly, 

 more closely punctate, the abdomen remotely and extremely 

 minutely so, shining. Length 8. 1-8.8 mm. ; width 3.7-3.9 mm. 

 Southern California pallidicornis Csy . 



Elytral punctures without evident decumbent hairs; size much larger.

10 Form broadly oblong, rather strongly convex, deep black through- 



out, shining ; head finely, sparsely punctate, the apical lobes feebly 

 impressed, the anterior canthus moderately narrowly rounded, fully 

 as prominent as the posterior ; antennas slender, black, with the 

 tip piceous ; prothorax transverse, more than three- fourths wider 

 than long, the sides broadly, subevenly arcuate, rather more so 

 and more converging at apex, becoming parallel behind the 

 middle, the apex circularly sinuate, two-thirds as wide as the 

 base, with the angles right and but slightly blunt; punctures 

 sparse and very minute, becoming strong but still rather fine and 

 sparse laterally, the lateral bead very fine ; scutellum rather small, 

 but slightly transverse, triangular; elytra as wide as the pro- 

 thorax, barely two-fifths longer than wide, the sides nearly 

 straight, the tip gradually and rather acutely ogival ; surface 

 smooth, rugulose apically, only moderately sparsely punctate, 

 finely so suturally, rather strongly and somewhat coarsely toward 

 the sides, the margin very finely reflexed ; prosternum minutely, 

 sparsely punctate, the abdomen and hind femora still more 

 sparsely, minutely and feebly. Length 10.0 mm. ; width 4.9 

 mm. Locality unrecorded but probably southern California. 



degener n. sp. 



Form relatively less broad, the largest species of the group, convex, 

 black, rather dull in lustre, the elytra subopaque ; head somewhat 

 finely, closely punctate, minutely and less closely posteriorly, 

 scarcely impressed at the apical lobes, the anterior canthus very 

 broadly rounded, not quite as prominent as the posterior; pro-
