206 MEMOIRS ON THE COLEOPTERA 



Prothorax very small, scarcely more than half as wide as the elytra, 

 black, the elytra feebly picescent, feebly, the elytra rather strongly, 

 shining; head nearly as in expansa but with the vertexal pit almost 

 obsolete; prothorax as in obsoleta but relatively much smaller; 

 elytra in form and sculpture nearly as in obsoleta, the three raised 

 lines on each evident, the external shortest and composed even more 

 evidently of close-set irregular tubercles; legs much shorter and still 

 more slender than in any of the preceding, the size decidedly smaller. 

 Length 14.0 mm.; width 6.8-7.4 rnm. California (Bolcan Mt., 

 5000 feet) brevipes n. sp. 



3- Sides of the prothorax rather broadly concave and gradually, though 

 more or less strongly, reflexed as in the preceding species 4 



Sides of the prothorax more narrowly and abruptly, very steeply, though 

 not more strongly, reflexed; legs and tarsi unusually short, nearly 

 as in brevipes but much stouter, with slender tarsi, their general 

 appearance nearly as in discreta though shorter 8 



4 Legs and especially the tarsi unusually stout; lateral edges of the 

 prothorax distinctly thicker. Body stout, deep black throughout, 

 subopaque, the elytra slightly shining especially suturally and on 

 the broad inflexed sides; head feebly, transversely impressed, 

 coarsely, somewhat closely punctate, with a deep impression at the 

 middle of the vertex; prothorax fully one-half wider than the median 

 length, the apex much narrower than the base, very deeply, circu- 

 larly sinuate, the angles acute, not blunt at tip; sides strongly, sub- 

 evenly arcuate from the apical angles to the very feeble sinuation 

 before the basal angles, which are acute and slightly prominent; 

 base posteriorly .suboblique laterally, the surface flat, with a very 

 strong and transversely arcuate tumescent swelling at about basal 

 third, coarsely, deeply and very closely but not coalescently punc- 

 tate, more sparsely on the anterior transversely sinuate slope of 

 the ridge and sparsely as well as more coarsely toward the sides, the 

 edges densely, rugosely punctate; elytra oblong-oval, parallel, widest 

 at the middle, nearly one-half longer than wide, almost one-half 

 wider than the prothorax, the sides evenly arcuate, rapidly rounding 

 basally and similarly so apically, the apical lobe broad, obtuse, 

 rather distinct; upturned margin rather thick and uneven, the sur- 

 face but very feebly convex, with two feebly impressed furrows on 

 each, also somewhat transversely creased, the granules very distinct 

 laterally; inflexed sides finely, sparsely granulose; abdomen some- 

 what shining, slightly crumpled, finely, rather sparsely, subasper- 

 ately punctate; legs as usual, very strongly, densely sculptured and 

 with very short stiff hairs. Length (cf ) 18.0 mm.; width 8.9 mm. 

 California torpida n. sp. 



Legs unusually stout, the tarsi long and relatively very slender. Body 

 more corpulent than usual, black, feebly shining, the elytra slightly 

 picescent and rather strongly shining; head broadly and feebly im- 

 pressed transversely, strongly and closely punctate; antennae slender, 

 about as long as the prothorax, the third joint one-half longer than 

 the fourth; prothorax subparallel, with broadly rounded sides be-
