NORTB OF MEXICO. 309 



sculpture consisting of punctures sometimes fine, al others rather coarse, rather denselj 

 lmt irregularly placed and never muricate, never arranged in rows. The femora are 

 mutic in both sexes. The thorax is also narrower af base than in the two preceding spe- 

 cies. The elytra ol the female are always broadlj oval, those of the male elongate, 

 scarcelj broader than the thorax. 



Occurs in California, from San Francisco to San Diego on the coast 3 and inland from 

 San Jose to Tejon. Specimens have been senl from Sonora. 



Length .60-.80 inch.

Differs from the preceding in the rather deeper emargination of the base of the elytra, 

 and by the humeral angles a little more prominent. The elytra are always opaque to a 

 greater or less extent, and very densely rauricately punctured or almost granulate. The 

 femora are mutic. 



Occurs in northern California and Oregon, where it replaces quadricollis of tin- south- 

 ern regions. 



Length .54-.68 inch.

From all the other species this may he readily distinguished by the elytra! sculpture, 

 consisting of rows of moderately elevated, rather smooth tubercles with opaque interspaces. 

 Its form i-* similar to the male of quadricollis. I have placed it in association with extri- 

 eata, a species with armed anterior femora, although is lemma are scarcely toothed, but 

 strongly sinuate near the tip. The other preceding species have the femora of both sexi - 

 entirely without either a tooth or the suspicion of a sinuation. The specimens in our col- 

 lections appear to he rather poorl) developed, and from what occurs in other species it is 

 inferable that fully developed forms may have a very distinct tooth in the males. I have 

 united aspt /•" a- a synonym, although the specimen is not before me. I believe it to be 

 merelj a more roughlj sculptured form, bearing the same relation to ,/,■>/, mlata that nsj,,. 

 rata does to /.< dinoides. 



Occurs as follows; granvlata, Oregon; obtusa, California; aspera, New Mexico. 



The three specimens scarcely varj from .60 inch. The last synonym is placed here 

 doubtfully. Should it prove to be identical witli granvlata, this name must be suppressed 

 and the name ofSolier used instead.

Readily distinguished from all others of the sub-section bj the very evident tooth of 



the anterior femur of the male, as well as },\ the rather more slender form of that - \
