tip as in some Pasimachi. Length (cf) 9.7 mm.; width 3.8 mm. 

 California (Lake Co.), Fuchs contractus n. sp. 



Mandibles elongate, as long as the head and neck or very nearly 5 



5 Mandibles unusually long, fully as long as the head and neck, the 

 median tooth of the left rather abrupt and strong, of the right not 

 quite so developed; palpi slender and pale as usual; head with the 

 usual two longitudinal folds near the eye inclosing two setigerous 

 punctures; prothorax apparently longer than wide but actually a 

 little wider than long, formed as in the preceding; elytra two-fifths 

 wider than the prothorax, a third longer than wide, oblong-oval, 

 truncate at base, the humeri rather distinct and not broadly rounded; 

 surface convex, shining, with traces of very fine and obsoletely 

 punctulate striae suturally; basal part of the epipleura broader, 

 fully a fourth wider than the middle coxae; tibiae with feeble internal 

 brush in all the three examples at hand. Length 10.0-11.5 nim.; 

 width 3.9-4.5 mm. California (locality unrecorded), Levette 

 collection crassus Lee. 



Mandibles not quite so long and with the internal medial tooth of the 

 left very broad and obtuse; hind tibia in type with feeble brush of 

 short hairs, the penultimate antennal joint on the flat side nearly 

 three-fifths longer than wide and much narrowed basally from about 

 the middle; inner fold near the eye much broader, becoming narrow 

 posteriorly for a much shorter distance than in crassus; body through- 

 out broader than in crassus, the prothorax similar but larger and 

 similarly a little wider than the head but apparently barely at all 

 longer than wide; elytra larger, somewhat stouter but otherwise 

 nearly similar and with very fine vestigial striation; epipleura at base 

 rather more than a fourth wider than the middle coxae. Length 

 12.5 m .; width 4.9 mm. California (Monterey), Dunn. 



corpulentus n. sp. 



6 Body larger, very stout, deep black, shining; head very large, the 

 inner ridge broad, not cariniform though pointed posteriorly; man- 

 dibles slightly shorter than the head, with only the feeblest broad 

 swelling to indicate the median tooth possibly in part through 

 wear; prothorax large, apparently fully as wide as long, in general 

 form as in the other species; elytra large, not two-fifths wider than 

 the prothorax, a third longer than wide, broadly truncate at base, 

 with distinct though rounded humeri, the sides less arcuate than in 

 any of the three preceding; epipleura at base a fourth wider than 

 the middle coxae; hind tibiae in the type with a feeble short brush. 

 Length 13.5 mm.; width 5.0 mm. California (locality unrecorded). 



grandiceps n. sp. 



Sexual characters seem to be almost wanting, as in Pasimachus 

 and Scarites, and I am uncertain whether even the tibial brush 

 alluded to in the descriptions is truly a sexual character or not, 

 as it seems to be present in most of the specimens at hand, including 

 a large series of lavissimus, which is abundant in the suburbs of
