parallel elongate elytra, tliey resemble in appearance P. angi- 

 collis, Randall, and P. aterrimus, Escli., but differ by the eyes 

 being less prominent, the head less narrowed behind, and the 

 hind angles of the prothorax less prominent ; the third and 

 fomth joints of the front tarsi of the ^J arc scarcely narrower 

 than the first and second, but, as in other species, are not fur- 

 nished beneath with papillge ; in both sexes the front tarsi are 

 broader and furnished beneath with more abundant long golden 

 hairs than in the ty \)ico.\ PatrobuSj and the fourth joint is very 

 distinctly emarginate. 



Three species of this group are known to me, agreeing 

 closely in fomi and sculptm-e, but differing chiefly in size, 

 form of prothorax, and length of trochanters. They may be 

 distinguished as follows : — 



Patrohus trochantericus. — Prothorax scarcely wider than 

 long, veiy slightly narrowed at base, sides feebly rounded in 

 front of the middle, and slightly sinuate behind ; hind angles 

 rectangular, slightly dentiform, base broadly emarginate at the 

 middle, oblique and subsinuate at each side near the angles ; 

 basal impressions broad, punctulate, not very deep ; carina of 

 angle feeble, limited by a distinct but short impression : hind 

 trochanters of male nearly as long as the femur, much at- 

 tenuated beyond the middle, and extremely narrow and sharp 

 at the tip ; of the female nearly half as long as the femur, 

 rounded at tip. Length 13-14 millims. Fort Crook, Northern 

 California (Dr. G. H. Horn). 



Patrohus californicus, Motsch. Bull. Mosc. 1859, ii. 123. — 

 Of the same size and general form as the preceding ; but the 

 basal impressions of the thorax are shallower, more distinctly 

 punctured, and the carina and impression near the angle are 

 wanting ; the base is much more oblique at each side, and the 

 angle is more dentiform. The male is unknown to me. The 

 hind trochanters of the female are as in the preceding, nar- 

 rowed towards the tip, which is rounded, and are about half 

 the length of the femur. California (Col. Motsch ulsky). 



Patrohus fulcratus, Lee, above described, differing by tlie 

 deeper basal impressions of the prothorax, by tlie base being 

 scarcely oblique on each side, by the angles, which arc less pro- 

 minent though more rectangular, and by the less elongated 

 and less attenuated hind trochanters of the male.
