MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 107 



Records. — The folloAving are the records laiown to me: 



Cuba: Rio Alinendares (Bierig, 1934, as morio; U.S.N.M.), Playa de Marianao 

 (Bierig, 1934, as nebuloaus; U.S.N.M. ), Laguna del Somorrostro (Bierig, 

 1934, as ciiheiitiia), Laguna La C'aiioa (Bierig, 1934, as ciibcn.sis), Caiuiito 

 del Guayabal (Bierig, 1934, as cuhcnsis), Aspiro (Bierig, 1934, as ctthensis; 

 U.S.N.M.), Rio Cristal (Bierig, in U.S.N.M.) 



Jamaica: (Hubbard, iu U.S.N.M.), Catadupa (Blackwelder station 405). 



Hispaniola: Haiti (Cameron, 1923; Scheerpeltz, 1933; Cameron colleotiou). 



Dominica: (Blackwelder station 254A). 



Specimens exajnined. — I have seen the unique type in Dr. Cam- 

 eron's collection, paratypes of each of Bierig's species in the United 

 States National Museum, and three examples collected by me in 

 1935-37. 



Hemarks. — Here again I am unable to separate Bierig's species 

 (cotypes) or distinguish them from Dr. Cameron's species or my own 

 siDecimens. The species is distinguished by its dense sculpture and 

 uniform color. The description was drawn from the Dominica 

 example. 



The type of nebuJosus' was taken on beach sand; that of cubensis 

 on soft mud; my examples were taken along streams.

 1.3 mm. (From Cameron.) 



Type locality. — St. Vincent, Leeward side. 



Types. — Holotype, male, and alk)type, female, in the British 

 Museum. 



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



St. Vincent: (Cameron, 1913; British Museum; Cameron collection; Long and 



Mutchler, 1917). 

 Grenada: (Cameron, 1913; British Museum; Cameron collection; Leng and 



Mutchler, 1917). 



Specimens examined. — I have seen the two types and four others in 

 i\\& British Museum and two examples in Dr. Cameron's collection. 



Remarks. — I have examined specimens of this species only briefly 

 and caimot voucli for its characters. It appears to be distinguishable 

 by the arrangement of color. 



I find no record of its habits.
