TENEBRIONID/E 125 



indefinitely impressed, finely, sparsely punctate anteriorly, gradu- 

 ally coarsely, densely and unevenly so toward base; antennae mod- 

 erately stout, the spongiose areas of the tenth joint almost uniting 

 on the sides; prothorax two-fifths wider than long, widest slightly 

 before the middle, the sides parallel and broadly, evenly arcuate to 

 the tip of the moderately advanced, rather blunt and briefly vibrissate 

 apical angles, very feebly sinuate toward base, the angles much 

 produced posteriorly, with their apices blunt, resting within the 

 reflexed humeri; base deeply bisinuate, wider than the apex, which is 

 deeply and broadly sinuate; surface nearly flat, with rather coarse 

 close impressed punctures, a narrow and slightly interrupted median 

 line and a few isolated spots more embossed and smooth, feebly 

 concave and reflexed laterally, with the punctures not coarser but 

 sparse; scutellum small, acute, as wide as long, not sunken; elytra 

 fully three-fourths longer than wide, barely wider than the pro- 

 thorax, the parallel sides feebly arcuate, the humeri right but 

 rounded, gradually and evenly ogival behind, the surface feebly 

 convex, the three feebly elevated lines of anastomosing glabrous 

 spots very uneven, the external very narrow, the side margins acute 

 and narrowly reflexed, extending nearly to the apex, the suture 

 throughout depressed, flattened and squamulose, a fine sutural 

 margin glabrous but not elevated; depressed areas closely, very 

 finely punctate, the yellow squamiform setae very small but distinct; 

 abdomen smooth, extremely minutely and remotely punctulate and 

 with excessively minute slender and depressed pale hairs. Length 

 (c?) 13.5 mm.; width 5.7 mm. Mexico (Federal District San 



Aug.), H. F. Wickham *abstrusa n. sp. 



Form much stouter and decidedly ventricose, dark piceous to blackish 

 in color, subopaque, the elytral lines more shining, especially in the 

 male, where they are strongly but unevenly geminate; head very 

 feebly and broadly impressed transversely, not coarsely but rather 

 closely punctate, each puncture with a small yellowish hair; pro- 

 thorax but slightly wider than long, the width never more than a 

 third greater than the length, the apex much narrower than the base, 

 moderately sinuate, the angles blunt at tip; sides broadly, subevenly 

 arcuate, gradually sinuate basally, the basal angles strongly, obliquely 

 everted and prominently acute; base broadly bisinuate; surface 

 not very convex, very densely, confluently and rather coarsely- 

 punctate, with a feebly defined impunctate line basally, and, on 

 each side of the middle, two smooth and inconstant spots, the 

 posterior oblique, the anterior rounded, the punctures medially 

 coarser toward base; sides narrowly and feebly reflexed, thickened; 

 hairs minute, pale; elytra but little longer than wide, obtuse and 

 moderately declivous behind, the sides arcuate, a fourth (cf) to 

 nearly two-fifths ( 9 ) wider than the prothorax, very moderately 

 convex, sloping evenly toward the base throughout the width, the 

 three feeble ridges, the two inner of which are unevenly geminate, 

 joined transversely by irregular lines, the depressions with minute 

 and rather stout pale hairs; abdomen smooth, very finely punctate
