REVISION OF TENEBRIONID SUBFAMILY CONIONTIN^S 79 



Form much more narrowly oval 2 



2 Body elongate-oval, shining, the elytra only faintly alutaceous, 

 black, the legs piceous-black, glabrous ; head only moderately 

 small, finely, sparsely punctate, the sides before the eyes not evi- 

 dently more prominent than the posterior canthus and very much 

 less so than in latus; antennas shorter and much thicker; pro- 

 thorax much less transverse, about two-fifths wider than long, 

 the sides evenly converging, evenly and feebly arcuate from base 

 to apex, the latter two-thirds as wide as the base, with the angles 

 only very narrowly rounded, the basal slightly blunt at tip ; sur- 

 face evenly convex, finely, rather sparsely and equidistantly 

 punctate throughout, rather less finely toward the sides, the lat- 

 eral bead very fine ; scutellum broadly triangular, polished, slightly 

 punctulate toward tip ; elytra fully two-fifths longer than wide, 

 otherwise nearly as in latus, except that the rather sparse punc- 

 tures are much finer and subequal to those of the prothorax medi- 

 ally, though becoming much finer but not at all closer laterally ; 

 under surface with much more minute and scarcely observable 

 hairs, the very obtuse prosternal process similarly unmargined. 

 Length 10.1 mm. ; width 5.0 mm. Exact habitat unrecorded. 



finitimus n. sp. 



Body nearly similar but noticeably cuneiform posteriorly, glabrous, 

 shining throughout above, the elytra not duller, piceous-black, the 

 elytra, under surface and legs rufescent ; head very small, strongly, 

 rather closely punctate, less prominent at the sides than in latus 

 but more so than vdfinitimus, noticeably more so than the poste- 

 rior canthus; prothorax more transverse, rather more than one- 

 half wider than long, the sides subevenly and strongly converging 

 from base to apex and evenly arcuate, more strongly so than in 

 finitimus, the angles nearly similar, the apex barely three-fifths as 

 wide as the base ; punctures only slightly less coarse and close 

 than in latus, stronger than \nfinitimus, even in size and spacing 

 throughout ; elytra fully two-fifths longer than wide, at base equal 

 in width to the prothorax, the sides thence feebly converging and 

 just visibly arcuate to about apical two-fifths, becoming gradually 

 thence strongly arcuato-convergent to the more narrowly ogival 

 tip, the punctures very fine, rather sparse and evenly distributed 

 throughout, minute laterally, very much smaller than those of 

 the pronotum, the contrast being much greater than in either of 

 the preceding species ; under surface finely, sparsely punctulate and 

 just visibly micro-setigerous, the prosternal process less obtuse but 

 wholly unmargined. Length 9.9 mm. ; width 4.6 mm. Island 

 of Sta. Cruz insularis Csy. 



Body somewhat cuneiform behind the prothorax, almost as in insularis 

 throughout, except that the prothorax is shorter and more trans- 

 verse and the punctures, especially those of the elytra, much more 

 close-set, deep black throughout, the legs piceo-rufous distally; 

 head nearly as small as in insularis, evenly convex, similarly
