8 MEMOIRS ON THE COLEOPTERA 



to the base and feebly arcuate; base feebly lobed medially; surface 

 opaque, with very fine anastomosing irregular lines and fine anterior 

 transverse impression, between which and the apex the surface is 

 longitudinally rugulose; elytra evenly oval and widest at the middle, 

 nearly twice as long as wide, finely sparsely and evenly punctate, the 

 punctures well separated and not larger on the flanks, the scattered 

 foveae small and generally rather feeble. Length (cf 9 ) 16.5-19.0 

 mm.; width 5.4-6.7 mm. California (at various points in Tulare 



Co.). Rather abundant parvicollis Csy. 



A Similar to the preceding but larger, with the head (cf ) distinctly 

 narrower than the prothorax, the mandibles rather less prolonged 

 apically, the anterior impressions feebler, the front feebly rugulose 

 and the antennae longer; prothorax relatively not quite so small 

 and wider than long, the sides anteriorly more inflated, similarly 

 sculptured and similar at base but much more than half as wide as 

 the elytra, the latter nearly similar but with the sparse punctures 

 a little larger and the scattered fovese more distinct, not so evenly 

 oval and widest slightly behind the middle. Length (cT) 19.0 



mm.; width 6.7 mm. California (Tulare Co.) spissipes Csy. 



B Similar to parvicollis but larger and still more elongate, the head 

 not quite as wide as the prothorax, the front similarly nearly 

 smooth and with moderate impressions; prothorax relatively 

 larger and wider than long, more inflated anteriorly, the base 

 not so lobed in the middle, very feebly and transversely bisinuate, 

 the sculpture of the same nature but stronger; elytra still more 

 elongate, evenly oval, widest at the middle and with the punctures 

 well separated but much larger and stronger than in either of the 

 preceding, the surface less even and the foveae distinct. Length 

 (cf 9 ) 18.5-20.0 mm. ; width 6.0-7.0 mm. California (Tulare Co.). 



procerus Csy. 



The copulatory spicule throughout is of the same type, long, 

 slender and strongly bent downward apically. Procerus is I think 

 more nearly a distinct species than a subspecies. 



Group V (lecontei). 



In this group the body is decidedly elongate, rather strongly 

 sculptured and usually with shining integuments; it occurs in the 

 coast regions from Monterey to northern Oregon, so far as now 

 represented in my collection, and consists of four species and 

 several subspecies as follows: 



Elytra widest before the middle, gradually arcuately narrowed thence to 

 the acute apex; labrum subtruncate; body slender; lateral margin of 

 the prothorax fine and but slightly reflexed, attaining the base; head 

 and pronotum rugulose throughout. Length 15-16 mm. Cali- 

 fornia (southern coast ranges from Monterey to Sta. Barbara and 

 Fort Tejon) lecontei G. H. Horn
