OMUS AND ClCINDELA 15 



orbital setae only three in number in the type; antennae more 

 slender; prothorax a fourth wider than long, widest anteriorly, the 

 sides converging rather strongly and moderately arcuate thence 

 posteriorly, abruptly straight and more oblique for a considerable 

 distance before the base, the margin fine throughout, attaining the 

 base; surface opaque, more feebly rugulose basally, finely, longi- 

 tudinally creased apically and feebly, transversely so laterally, 

 the stria very fine; elytra one-half longer than wide, oval, obtuse, 

 widest at the middle, the punctures as in the preceding but smaller, 

 more feebly impressed, almost in mutual contact, the intervals 

 sericeous. Length (cf) 16.0 mm.; width 6.0 mm. California 



(Giant Forest, Tulare Co.), Dietz temperatus n. subsp. 



B Male stout, convex, more ventricose than in any of the preceding, 

 opaque, the elytra rather strongly shining; head moderately 

 rugulose; supra-orbital setae three or four in number; prothorax 

 as in temperatus, the sides as strongly oblique as in sequoiarnni, 

 feebly arcuate, the margins abruptly rounded at the immediate 

 base, which they attain; surface more confusedly rugulose apically 

 than in temperatus, more nearly as in hortii; elytra short, broadly 

 oval, widest at the middle, with very coarse deep punctures, which 

 are separated by nearly their own diameters suturally, dense 

 laterally, the interspaces notably shining. Length (cf) 14.8- 

 16.0 mm.; width 6.0-6.2 mm. California (Wawona, Mariposa 



Co.) compositus Csy. 



Elytral punctures, when present, perfectly simple and without trace of 



an acute anterior granule 2 



2 Elytra distinctly punctured; side margins of the prothorax attaining 

 the base. Body stout, convex, ventricose; head very feebly rugu- 

 lose, with slight impressions, the front with very fine sparse punctu- 

 lation; supra-orbital setae four in number; prothorax (c? 1 ) nearly 

 as long as wide, opaque, with very fine or obsolescent anastomosing 

 lines, though virtually smooth, the basal and apical rugulosity very 

 feeble; outline as in sequoiarum, or ( 9 ) larger, more transverse, 

 with slightly less converging sides; elytra evenly oval, rather pointed 

 at apex, widest at the middle, much broader in the female, the 

 punctures rather coarse and dense throughout though not very 

 deep. Length (cf 9 ) 15.8-18.0 mm.; width 6.0-7.0 mm. Cali- 

 fornia (Tulare Co., 6400 feet). Abundant and not more than usually 



variable tularensis Csy. 



A Similar to tularensis in every way, except that the body is not 

 quite so large and notably more slender in both sexes; head opaque, 

 with the rugulosity almost completely obsolete, the fine frontal 

 punctulation also indistinct; prothorax differing less sexually, 

 the sides strongly oblique and feebly arcuate in both sexes, the 

 surface nearly as in tularensis throughout but with the sculpture 

 still more obsolete; base perfectly straight and transverse in the 

 male type, or feebly bisinuate in a female recently received; 

 elytra narrower and more elongate than in tularensis though other- 

 wise similar. Length (cf 9 ) 15.0-16.8 mm.; width 5.5-6.2 mm. 

 California (Davenport, Tulare Co., 6500 feet) gracilior Csy.
