TENEBRIONID^E 213 



brown throughout; head deeply impressed transversely and on 

 the vertex, rather closely punctate, coarsely so anteriorly, less 

 coarsely thence to the base; prothorax short, fully one-half wider 

 than long, the apex evidently narrower than the base, not very 

 deeply, elliptically sinuate, the angles slightly acute, sharp; 

 sides evenly and strongly arcuate from the apical angles, barely 

 becoming straight at the basal angles, which are right and very 

 sharply denned; surface and sides nearly as in angustula but not so 

 evidently impressed and with the margins narrowly but not quite 

 so strongly reflexed, the median parts duller in lustre and the small 

 pale hairs more distinct; scutellum a little broader; elytra narrower 

 and less arcuate at the sides, parallel, four-fifths longer than wide, 

 not quite so convex, similarly parabolic at tip and steeply decli- 

 vous, the sparse granules much smaller, the erect hairs shorter; 

 abdomen distinctly, rather closely, evenly and asperately punc- 

 tulate throughout; prosternum sparsely punctate. Length (9) 

 12.8 mm.; width 4.8 mm. California (San Diego Co.). 



inepta n. subsp. 



Body narrow and very elongate, much more slender than any other species 

 of the genus, very convex and subparallel, moderately shining and 

 rather pale ferruginous-brown throughout; head distinctly im- 

 pressed transversely and deeply so at the middle of the vertex, the 

 punctures coarse, deep, generally well separated; prothorax small, 

 but little more than a fifth wider than long, throughout nearly as 

 in angustula and about as wide at apex as at base but with the basal 

 angles minutely everted and acutely dentiform, the thin and strongly 

 reflexed edges more coarsely crenulate; elytra about twice as long 

 as wide, one-half wider than the prothorax and between three and 

 four times as long, obtusely parabolic and steeply declivous behind, 

 the sides parallel, very feebly arcuate, rounding more basally and 

 rapidly rounding apically; surface very convex, subcylindric, the 

 granules very sparse but rather strong, the erect setae long; side 

 margins only slightly reflexed, moderately thin, strongly granulo- 

 serrate; abdomen subopaque, rather coarsely, very strongly granulo- 

 asperate throughout, the pale hairs unusually long and very con- 

 spicuous; legs rather short, slender. Length (9) 13.8 mm.; width 



5.5 mm. California (San Diego) tenax n. sp. 



7 Body oblong, parallel, moderately slender, dark red-brown, the 

 elytra slightly paler, shining; head deeply, transversely impressed, 

 rather coarsely, closely punctate; prothorax transverse, fully one-half 

 wider than long, the apex much narrower than the base, the sinus 

 very moderate in depth and elliptical, the angles but slightly less 

 than right and somewhat blunt; sides evenly, somewhat strongly 

 arcuate, the basal angles right; surface very moderately convex, 

 steeply declivous behind to the abruptly deplanate basal margin, 

 feebly bi-impressed at each side of the middle in apical three-fifths, 

 rather shining, coarsely, somewhat closely punctate, less coarsely and 

 very closely before about the middle, rather abruptly, strongly 

 reflexed, coarsely, closely punctate and rugose at the sides, the edges
