SCELOLrYPERUS g. n. 



Agrees In all respects with Luperus, but the hind tibiae are deeply 

 arcuate and furnished in their basal third with a strong triangular 

 tooth. I have only seen one specimen and do not know if the charac- 

 ter is sexual. 



S, tejonicns, n. sp. — Body beneath and legs black, head and eh'tra steel 

 blue, base of antennae and thorax dark yellow; head smooth with a strong 

 carina between the antennae; thorax rather broader than long, apparently 

 impunctate, sides rounded in front, narrowed towards th-e base; scutellum

The only specimen before uie is much broken and was taken at 

 Fort Tejon about the end of May, 



THRICOI.EMA, g. n. 



Elongate, nearly parallel, pubesceut, eyes small, head not constricted 

 behind, anterior coxae contiguous, 1st joint of the four anterior tarsi 

 longer than the others, claws simple, epipleurae of elytra excessively 

 feeble. I am unable to put this genus satisfactorily into any of the 

 tribes of Phyfophaga.
