TENEBRIONHXE 115 



erately converging, becoming straight posteriorly to the obtuse 

 but sharp though not at all prominent basal angles, the surface 

 broadly, evenly convex medially and with small but deep and 

 perforate, rather close-set and perfectly simple punctures, mingled 

 with a few that are very much smaller, the punctures becoming a 

 little smaller on the lateral slopes of the convexity and, toward the 

 sides, coarser and sparser though similar in form; elytra oblong-oval, 

 more than two-fifths longer than wide and, rather behind the middle, 

 almost three-fourths wider than the prothorax, the discal carina 

 on each strong, the space between them and across the suture flat, 

 the inner carina wholly obsolete, the general surface smooth, 

 shining, with very small and sparse granules, becoming very minute 

 and obsolescent toward the suture; legs moderate, cylindric, the 

 hairs very small, fine, sparse and inconspicuous, the tarsi notably 

 short. Length 22.0 mm.; width 12.4 mm. The type probably 



male. Southern California opimus n. sp. 



Pronotum granulate, the granules more or less small and well separated. 4 



Pronotum densely granulato-tuberculose throughout 5 



4 Form stout and strongly ventricose, black; head opaque, finely 

 granulate; prothorax quadrate, broader than long, the sides moder- 

 ately rounded, the margin finely crenulate, the apex emarginate 

 with the angles acute; base nearly truncate, the angles rectangular; 

 surface coarsely punctate along the margin, finely granulate medially; 

 elytra rounded-oval, very convex above, opaque, finely and sparsely 

 granulate, the basal margin denticulate at the sides, the latter 

 margined; surface with the outer costa extending two-thirds the 

 length of the elytra, the inner costa obsolescent; under surface 

 opaque, finely punctured. Length 14.5-23.0 mm.(!) California 



(Owen's Valley). [Asida actiiosa Horn] actuosus Horn 



Form much more slender, smaller in size, black, opaque, the prothorax 

 about two-fifths wider than long and two-thirds as wide as the elytra; 

 head minutely, rather closely punctate, the punctures gradually 

 but feebly asperulate posteriorly; prothorax widest but little before 

 the middle, with strongly rounded sides, converging and less rounded 

 apically and basally, strongly crenulate, the apical angles minutely 

 everted and acute, the basal obtuse but denticulate externally; base 

 broadly, rectilinearly truncate medially, thence anteriorly oblique 

 and arcuate to the angles; surface rather strongly convex medially 

 and with strong tuberculiform granules, becoming very fine on the 

 slopes of the medial convexity, broadly and feebly concavo-de- 

 planate laterally and more densely, rather coarsely rugulose; elytra 

 very evenly elongate-oval, one-half longer than wide, the ends of the 

 basal margin acutely dentiform, the general surface transversely, 

 rather strongly convex throughout, finely, sparsely granulate, the 

 outer costa fine but rather strong, the inner evident though feeble, 

 joining the outer a little behind apical third; abdomen finely, 

 asperately punctate. Length (cf ) 16.0 mm.; width 7.8 mm. Utah
