OMUS AND ClCINDELA 13 



deeply but finely vermicularly rugulose throughout, or ( 9 ) fully 

 a third wider than long but otherwise similar, except that the rugu- 

 losity is a little coarser and stronger, almost as in some modifications 

 of the californicus type; elytra oval, widest near the middle, more 

 acutely tapering apically in the female. Length (c? 9 ) 13.5-15.0 

 mm.; width 5.2-5.9 mm. California (Forest Hill, Placer Co.). 



fraterculus Csy. 



Male and female nearly similar and but very moderately stout, generally 

 less shining; elytral punctures very coarse and deep, the interspaces 

 rather shining; head nearly as in the preceding; prothorax (9) a 

 fifth wider than long, differing greatly in shape from fraterculus, 

 being widest at apical third, the sides thence oblique and more nearly 

 straight to the base, the side margins and sculpture nearly similar; 

 elytra subevenly oval, gradually acutely narrowed apically, widest 

 at the middle, the strong punctures distinctly separated, the inter- 

 spaces with scattered small punctures; at the sides the coarse punc- 

 tures are very dense and everywhere somewhat aciculate. Length 

 (9) 14.5 mm.; width 5.25 mm. California, Levette. 



punctifrons Csy. 



A Similar, but the labrum has only four instead of six setigerous 

 punctures in the type; prothorax (c?)' nearly as in the female type 

 of the preceding in every way and with the base similarly trans- 

 verse and feebly bisinuate; elytra rather broader than in the pre- 

 ceding female type, less gradually acute posteriorly, the punctures 

 still coarser and more conspicuous, in mutual contact and very 

 coarse on the flanks; foveae rather large but very few in number, 

 feeble and inconspicuous. Length (cf ) 14.0 mm.; width 5.28 mm. 



California (Sierra Co.), Fuchs degener Csy. 



B Similar in general form, the female a little stouter than the type of 

 degener; head similar; prothorax a little broader, a fourth wider 

 than long, as in degener, except that the sides from anterior third 

 to the apex are straighter; elytra barely one-half longer than wide, 

 oval, gradually acute at apex, only feebly convex, the side margins 

 strongly reflexed basally as in degener and much more elevated than 

 in punctifrons; sculpture differing greatly from any of the three 

 preceding, the punctures being less coarse, still more irregular in 

 form and densely coalescent throughout, the interspaces duller, 

 with much stronger micro-reticulation and with scattered small 

 punctures. Length (9 ) 14.0 mm.; width 5.4 mm. California, 

 Levette confluens Csy. 



I am rather of the opinion that cribripennis is a species different 

 from blaisdelli and that confluens has higher value than here sug- 

 gested for it, but feel that the modern tendency to combine rather 

 than to differentiate and to attribute structural differences in 

 related forms to accidental causes, should be respected at least to 

 some extent. In the females of this group the coarse setigerous 

 punctures forming a series bordering the acute apex of the last
