MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 321 



Records. — The following are the records known to me : 



Hispaniola: Dominican Repubuc, Valle Nuevo (Darlington, in M.C.Z.), Con- 

 stanza (Darlington, in U.S.N.M.). 



Specimens exammed. — I have seen only the three tj^pes. 



Remarks. — This is a distinctly subterranean species in appearaiiee. 

 It is readily distinguished from reductum and borinquense by the 

 absence of serial punctm-es on the pronotiim and elytra as well as by 

 the male characters, but it belongs in tlie same undescribed subgenus. 



The types in the Museum of Comparative Zoology wore found in 

 cloud forest, probably under ground cover.
