In addition to San Jose del Cabo, it occurs at Miraflores, 

 Sierra El Chinche, Santo Domingo del Taste and Sierra 

 San Lazaro. 



OcHODyEUS PENINSULARIS n. Sp. 



Oval, slightly oblong, fulvo-testaceous, sparsely clothed 

 with short fulvous hair. Antennae, except the first two 

 points, piceous. Head very coarsely punctate, occiput 

 slightly piceous, clypeus oval at middle, slightly sinuate 

 each side, the margin narrowly reflexed, front not tuber- 

 culate. Thorax fully twice as wide as long, disc convex, 

 not closely granulate, a vague median depression posteri- 

 orly. Elytra about one-fourth longer than broad, the 

 strise feebly impressed, moderately coarsely and closely 

 punctate, intervals flat, very irregularly biseriately punc- 

 tate. Length, .16-.22 inch. ; 4-5.5 mm. 



The mentum is a little longer than wide, deeply im- 

 pressed its whole length and emarginate in front. 



In the six specimens examined, in which both sexes are 

 undoubtedly represented, I find no armature either of the 

 femora or tibiae. The male hind tibise are, however, 

 somewhat shorter and more hairy. This species is most 

 closely related to biarmatus, and more especially the 

 female, which has not the clypeal tubercles of the male. 

 In both sexes of biarniatns the condyle of the hind femur 

 forms a narrow plate along the posterior edge, terminating 

 in a small tooth, one-third from the knee. No such 

 structure exists in this species.
