REVISION OF TENEBRIONID SUBFAMILY CONIONTIN^ 153 



the apical sinus very deep, the angles not deflexed, rounded ; sur- 

 face coarsely, deeply and closely punctured throughout, not dif- 

 fering much near the sides, which are explanate, the bead fine and 

 feeble ; elytra but just visibly longer than wide, rounded at the 

 sides and obtuse behind, the immediate apex sharply ogival, the 

 sides becoming parallel toward base ; surface vertically declivous 

 and then slightly inflexed behind in profile, the punctures strong, 

 moderately separated, muricate, becoming granular posteriorly; 

 prosternum densely punctato-rugose, the process moderately con- 

 stricted between the coxa? ; abdomen finely but strongly, more or 

 less closely punctate. Length 5.8-7.8 mm. ; width 3.7-4.9 mm.

Pronotum very unevenly punctate, with large patches devoid of punc- 

 tures , 4 



4 Body large in size, oblong-ovoidal, blackish-castaneous to rufo- 

 piceous in color, shining ; head rather coarsely, deeply and densely 

 punctate, with the usual basal impunctate area; antennal club 

 fusoid, of about four joints ; prothorax scarcely two and one-half 

 times as wide as the median length, the sides much more parallel, 

 broadly rounded, more converging anteriorly, the apical sinus 

 very deep as usual, the angles more broadly rounded than in glo- 

 bosus ; surface sparsely and rather finely but very deeply punctate, 

 the punctures becoming close and mingled with larger punctures 

 on the explanate lateral part, the bead rather coarse though only 

 feebly elevated and distantly punctured ; elytra but little longer 

 than wide, at the middle evidently wider than the prothorax, the 

 sides parallel and broadly arcuate, rapidly converging and rounded 

 behind, the surface nearly as in globosus but more rugose, the 

 punctures strongly muricate, rather sparse, less sparse and granu- 

 lose posteriorly as usual ; pubescence long, subdecumbent and 

 conspicuous toward the sides posteriorly and much more conspic- 

 uously so than in globosus ; prosternal process only moderately 

 constricted between the coxag ; abdomen rather sparsely but dis- 

 tinctly punctate. Length 11.0-12.0 mm.; width 6.4-7.0 mm. 

 Probably San Pedro, G. W. Dunn grossus Csy. 



Body similar to the preceding in general characters but uniformly 

 smaller and relatively narrower, polished, castaneous in color; 

 head notably smaller in size but otherwise similar; prothorax a 

 little shorter and more narrowed at apex but otherwise similar ; 

 elytra as in grossus, except that they are less inflated and never more 

 than just visibly wider than the prothorax, the sculpture somewhat 

 less coarse and notably less close ; under surface nearly similar, 

 except that the prosternal process is less abbreviated and with the 

 punctuation less coarse, the metasternum, especially, more sparsely 

 and much less conspicuously so. Length 9.4-10.7 mm. ; width 

 5.5-6.0 mm. Sta. Barbara, G. W. Dunn solidus n. sp. 



Body shorter, broader and more evenly oblong-oval in form than in 

 grossus and smaller in size, though unusually large for the genus,
