 eus confluently punctured, without a median ridge ; flagellum 

 barely rufescent beneath ; hair on thorax as described above.

 sumably collected near Los Angeles. 



If the excavated clypeus is a generic character, then it would 

 seem thatil/. aiigclaruui, along with M. prosopldis, Ckll., and M., 

 izU'Cara, Cresson, should go in Robertson's genus Chelojtomosides.

 Beetles. 



BY PROF. J. J. RIVJiRS. 



In Europe and America many entomologists give great at- 

 tention to beetles found living in or about ants' nests in social 

 relationship. There are several peculiar species of several genera 

 in the family of Stephalinidje that are taken in no other situation. 



It is not a rule among insects that the "lion lies down with 

 the lamb," yet among ants this law is a natural one with certain 

 favorites. In the neighborhood of Santa Monica the following 

 species occur with ants: Eidabis laticoniis, Casey; Eulabis pu- 

 hescens, Lee; Anclwuiina costatiiui, Lee; Apocrypha anthicoi- 

 des, Esch. 



The two species recorded in order first and second run along 

 the well-worn paths with the ants in perfect harmony, and enter 

 their nests; the latter two are found with ants under stones in 

 perfect social peace.
