OMUS AND ClCINDELA 9 



Elytra evenly elongate-oval, widest at the middle; labrum arcuately 

 produced and frequently narrowly truncate at apex; habitat less 



southern 2 



2 Sides of the prothorax strongly rounded, becoming subparallel in 

 nearly apical half. Body slender (cf), less slender (9), rather 

 convex, shining; head narrower than the prothorax, coarsely wrinkled, 

 the front medially smoother, not punctate; prothorax coarsely but 

 not very strongly, vermicularly rugulose, the base transverse, not 

 evidently bisinuate; anterior transverse impression fine but distinct; 

 side margins sharply reflexed, strongly near the base, which they 

 virtually attain; elytra fully three-fourths longer than wide, with 

 evenly arcuate sides and small, widely separated punctures, becoming 

 closer but scarcely at all larger on the flanks. Length (cf 9 ) 17.0 

 mm.; width 5.8-6.0 mm. California (near San Francisco), Dunn. 



elongatus Csy. 

 Sides of the prothorax oblique and feebly arcuate from near the apex to 



the base 3 



3 Front generally not at all punctulate though smooth or but feebly 

 rugulose; southern coast regions. Body elongate, strongly convex, 

 shining; head distinctly narrower than the prothorax, the front 

 feebly rugulose and with traces of very minute sparse punctulation; 

 prothorax slightly wider than long, widest near apical fourth, where 

 the sides are inflated and rounded; side margins as in the preceding, 

 the surface more strongly vermiculato-rugose, as in californicus though 

 much more feebly; elytra two-thirds longer than wide, unusually 

 convex, the punctures small, everywhere widely separated. Length 

 (d 71 ) 16.0 mm.; width 5.5 mm. California (near San Francisco), 



Dunn dunni Csy. 



A Narrower and still more elongate, the median part of the front 

 very smooth and sculptureless; labrum with the median lobe 

 much produced, abruptly truncate at tip; rugulosity strong; 

 prothorax with the sides converging and evenly, moderately 

 arcuate from apex to base, the margin still more strongly reflexed, 

 especially apically and basally; surface similar; base broadly 

 arcuate medially; elytra narrower and longer, the punctures 

 stronger, closer laterally, each similarly with a small acute an- 

 terior granule, the fovese small and not conspicuous. Length 

 (cf 9 ) 16.5-18.0 mm.; width 5.5-6.2 mm. California (Carmel, 



Monterey Co.) regularis Csy. 



B Smaller and still narrower, notably slender and not so convex, less 

 shining; head similar, the truncate lobe of the labrum not quite 

 so prominent; prothorax throughout nearly as in regularis, barely 

 at all wider than long; elytra almost twice as long as wide, very 

 evenly oblong-oval, the punctures similarly small, well separated, 

 aciculate and strongly granuliferous, the interspaces dull and 

 more strongly micro-reticulate than in either of the preceding. 

 Length (cf ) 15.5 mm.; width 5.2 mm. California (Monterey Co.),

Front generally finely, sparsely punctulate, the punctures gradually 

 obsolescent in some forms, northern coast regions. Body moderately
