MONOGRAPH OF WEST INDIAN STAPHYLIMDAE 473 



Specimens examined. — I have seen 31 specimens from the Museum 

 of Comparative Zoology and seven collected by me during 1935-37. 



RemarJcs. — Although I found no examples identified as this species 

 in the British Museum or in Dr. Cameron's collection, there is little 

 doubt of the identity of the species. One example labeled viUs 

 Sharp in Dr. Cameron's collection seems to belong to this species, 

 but I cannot state whether laticollis and vilis may be the same. 



My examples were taken among the rotting "fruit" of an imported 

 palm and under stones and sand along streams.
