California, from Saa Diego to Cape Saa Lucas; Arizona, Mexico. The 

 synonym belongs to a form in which the apical constriction of the protho- 

 rax is less obvious; this variation serves to confirm the opinion above ex- 

 pressed regarding the species of Scypliophorus. The specimens were found 

 exclusively under decaying Opuntia leaves. 



RHODOBuENUS n. g. 



I would also separate as distinct the usually red species with black spots, 

 which agree with Cactophagua in the form of the gular peduncle, but differ 

 in the tibiie subtruncate at the tip, with the outer angle obtuse, but distinct, 

 the third joint of the tarsi is equally broad and spongy beneath, but the 

 brush is divided b}' a narrow line; the first joint is hairy at the tips, while 

 the second is der.sely hairj^ with a narrow median line. The elevations 

 above the insertion of the antennae are much stronger, and the scape of the 

 latter comparatively longer. The mesosternum is also narrower than the 

 other genera. The species are found on tlowers, mostly rose-bushes; but 

 two are known to me in our fauna; the first is red, with black spots; the 

 second brown, irrorate with grayish round spots, which surround the punc- 

 tures.

Tribe IIL CAI.AXDRIJUI. 



This tribe consists of small species, in which the mandibles are pincer- 

 shaped, and not everted; the club of the antennae not compressed, and the 

 mesothoracic epimera transverse, acute at the outer end, and intervening 

 between the humeral part of the elytra and the base of the prothorax. The 

 anterior part of the last dorsal segment of the abdomen is channeled for the 

 reception of the sutural edge of the elytra, almost as in Anthribidce. This 

 is a very peculiar character, and I find no trace of it in the other genera in 

 our fauna. 



CAIiANDRA ClauV. 



This genus differs from the others contained in the tribe, but not repre- 

 sented in our fauna, by the antennal club being oval, the corneous part sep- 

 arated from the sensitive part by a transverse line; the sensitive part being 

 convex, and somewhat pointed. The body is narrow, and elongate, quite 

 different to that observed in the genera of the two preceding tribes, rather 

 resembling Bhina in miniature. 



Three species occur in our fauna; they have been distributed in the ce- 

 real grains upon which they depredate, so that their original habitat cannot
