coming very feebly and broadly sinuate toward the acute basal 

 angles, the apex much narrower than the base, deeply sinuate, the 

 angles acute but not everted; surface deeply and closely punctate, 

 more coarsely toward the sides; elytra widest behind the middle, 

 two-fifths longer than wide, three-fifths wider than the prothorax 

 and only about twice as long, the sides unusually converging and 

 less arcuate basally, the surface feebly convex, nearly even, with 

 fine sparse granules laterally, becoming obsolescent and very fine 

 toward the suture; legs moderately long, the hind tarsi more than 

 three-fifths as long as the tibiae. Length (cf) 16.5 mm.; width 8.7 

 mm. California (Julian) discreta n. sp. 



Legs and tarsi both rather slender, nearly as in obsoleta and allied forms. . 5 



5 Prothorax strongly narrowed toward apex, the latter very much 

 narrower than the base 6 



Prothorax more parallel, the apex generally but little narrower than the 

 base 7 



6 Body deep black throughout and only moderately shining, nearly 

 as in obsoleta but relatively more parallel, convex and subcylindric, 

 the elytra each with one or two fine irregular subimpressed lines 

 toward the suture; head strongly, rather loosely punctate, deeply 

 impressed transversely in but little more than median half, the 

 vertexal pit distinct; prothorax fully a third wider than long, strongly, 

 subprominently rounded at the sides at about the middle, the sides 

 converging and becoming straight to the acute basal angles, feebly 

 arcuate and strongly converging to the anteriorly prominent acute 

 apical angles, the surface transversely convex near basal third and, 

 anteriorly, feebly impressed sublaterally ; elytra three-fifths to three- 

 fourths longer than wide, subevenly oval. Length 16.3-17.5 mm.; 

 width 7.3-7.7 mm. California (Bolcan Mt., 5000 feet), Ricksecker. 



longula n. sp. 



Body black, feebly shining, the elytra dark rufo-piceous and strongly 

 lustrous; form much stouter, less convex and less cylindric than in 

 longula; head moderately punctate, not deeply impressed trans- 

 versely in median two-thirds, the vertexal pit shallow; antennae short 

 and only moderately slender; prothorax large, nearly two-fifths wider 

 than long, otherwise nearly as in the preceding, except that the 

 convening sides become sinuate in front of the prominent basal 

 angles, the surface similar and rather strongly, closely punctate; 

 elytra but little more than one-half longer than wide, subevenly 

 oval, almost imperceptibly wider behind the middle, two-fifths wider 

 than the prothorax and two and two-thirds times as long, the apical 

 lobe stronger and more differentiated than in longula. Length 

 19.5 mm.; width 9.3 mm. Southern California, Dunn. 



convergens n. sp. 



7 Form rather stout and moderately convex, black or blackish, feebly, 

 the elytra moderately, shining; head feebly impressed transversely 

 in but little more than median half, rather finely to more strongly, 

 somewhat closely punctured, the vertexal pit obsolescent typically; 

 prothorax but slightly wider than long, subparallel, with more or
