REVISION OF TENEBRIONID SUBFAMILY CONIONTIN-(E II7 



4 — Form still stouter, oblong-oval, convex, deep black, somewhat 



alutaceous, the elytra more shining; head rather finely, very 

 sparsely punctate, more closely so near the transverse suture, the 

 sinus moderately broad, deeply subangulate, the anterior canthus 

 full, somewhat less prominent than the posterior; prothorax 

 three-fourths wider than long, the sides very feebly converging 

 and almost straight, or with a feeble ante-basal sinus, from the 

 base about to the middle, then rounding, becoming strongly con- 

 verging and just visibly arcuate to the apex, which is broadly 

 sinuate and two-thirds as wide as the base, the angles right and 

 rather narrowly rounded; surface very minutely, sparsely punc- 

 tate, becoming broadly somewhat coarsely but not very closely so 

 laterally; base somewhat more strongly bisinuate than in obtusa; 

 scutellum small, transversely triangular; elytra as in obtiisa but 

 barely a third longer than wide, nearly smooth, subopaque pos- 

 teriorly, having numerous fine and generally subtransverse, an- 

 astomosing creases throughout, the punctures sparse but rather 

 strong, becoming quite close-set and subrugulose or with trans- 

 versely sublineate extensions laterally ; prosternum rather finely 

 but strongly punctate, the process long, the post-coxal part oblong 

 with but feebly arcuate sides and rounded tip, broadly constricted 

 at the cox£e, inimargined except finely along the coxae ; hind 

 femora and abdomen very sparsely punctate. Length 10.8 mm. ; 

 width 5.75 mm. Nevada (Carson City), — H. F. VVickham.

5 — Body oblong, deep black, the tarsi piceous ; upper surface alu- 



taceous, the elytra more shining though posteriorly opaque, head 

 rather sparsely but somewhat strongly punctured, finely toward 

 base, the sinus nearly as in the preceding, the anterior canthus 

 rather broadly rounded and almost as prominent as the posterior; 

 prothorax two-thirds wider than long, the sides subevenly and 

 moderately arcuate throughout, not quite becoming parallel even 

 at base, the apex rather deeply sinuate, scarcely more than three- 

 fifths as wide as the base, the angles right and very distinct, 

 scarcely at all blunt ; surface sparsely, extremely minutely punc- 

 tate, becoming broadly quite coarsely but scarcely less sparsely so 

 laterally; base rather strongly sinuate near each side ; scutellum 

 small; elytra not quite one-half longer than wide, parallel, 

 obliquely and rapidly narrowed in posterior third to the apex, 

 which is much more angulate than in the preceding, the pu- 

 bescence very conspicuous, fulvous; surface nearly smooth, the 

 anastomosing fine creases only distinct posteriorly, finely, remotely 

 punctate, more strongly and less sparsely so laterally but still 

 comparatively finely; prosternum rather strongly punctate, un- 

 margined except finely along the coxa? ; hind femora and abdomen 

 rather finely but unusually distinctly, though remotely, punctate; 

 tarsi moderately slender. Length 10. 9-1 1.5 mm.; width 5.7— 

 5.85 mm. Utah (Marysvale), — H. F. Wickham.
