The California Academy of Sciences has a small series 
of this species, as well as the holotype. Below is a short 
redescription, based on notes taken on the holotype (No. 
154), seen in 1946, and checked at that time with the more 
recent specimens. The species should be left in my group 
A, in which the male does not have a row of stout apical 
teeth on the metatibia, and should be placed near excors 
and tenuilineata. 
Color luteous, with the antennae brown. Pubescence tan- 
iiish cinereous, depressed. Elytra with humeral and scutel- 
lar dark markings. Head narrowly ovate, the surface dense- 
ly punctured, with the intervals punctulate. Median im- 
] tressed line fine, distinct down to the level of the hind 
margin of the eyes. Antennal calluses denuded, smooth, of 
moderate size and only slightly raised. Eyes transverse, 
moderately narrow, emarginate. Male antennae 3 1/2 as 
long as an anterior tibia. Segment I flat, straight, reaching 
almost to occiput; II almost as long as I, flattened, slightly 
CLU'ved; III short, 1/3 as long as II, 2/3 as long as IV; IV 
tile largest of the succeeding segments, rest just slightly 
shorter, slender, slightly flattened. Female antennae with 
segment I reaching hind margin of the eye; II almost as 
long as I; HI approximately 1/2 as long as II; IV and fol- 
lowing equal, almost as long as II. Pronotum campanuli- 
foi’m, 1/4 longer than broad; median impressed line dis- 
tinct from 1/4 from base to 1/3 from apex; a prominent 
impression at middle of base. Anterior tibiae of male with 
two spurs, the inner slightly the shorter ; male anterior tar- 
si not modified. Posterior tibial spurs spiniform, only very 
slightly broadened. Underside not marked. Legs marked 
as in polingi Werner. 
Distribution: Baja California: Beside the holotype from 
San Jose del Cabo there are specimens in the California
