MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 285 



two additional minute denticles laterally; the median denticles are 

 somewhat enlarged at base; gular sutures moderately separated, fee- 

 bly diverging posteriorly; with minute punctures so dense as to 

 appear like ground sculpture, but surface still shining. Pronofuni 

 one-nintli longer than wide, anterior angles narrowly rounded, sides 

 feebly emarginate in front, moderately arcuate posteriorly; with 

 scarcely a trace of midline; not very distinctly punctate but with 

 sculpture forming irregular punctiform depressions, without addi- 

 tional ground sculpture. Elytra not punctured but with distinct and 

 strong tuberculi separated by less than their diameter; without 

 ground sculpture except basally along suture. MaU. fourth and fifth 

 sternites with a transverse fold, seventh feebly broadly emarginate; 

 eighth sternite with a deep triangular emargination, apex narrowly 

 rounded, aI)out two-thirds as deep as wide, and with outer angles 

 rounded. Female^ eighth sternite rounded; eightli tergite rounded. 

 Length, 2% to 3 mm. 



Type locality. — Haiti. 



Types. — In the collection of Dr. Cameron. 



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



Cuba: (Bierig aud Cameron collection, as hicoloricornis) , Soledad (Darlington, 

 in M.C.Z. and U.S.N.M.), Aguadores in Oriente (Darlington, in M.C.Z. and 

 U.S.N.M.), Cayamas (Schwarz, in U.S.N.M.), Baragua (Christenson, in 

 U.S.N.M.). 



Hispaniola: Haiti (Canaeron, 1913; Leng and Mutchler, 1917; Scheerpeltz, 1933), 

 Desbarriere (Darlington, in M.C.Z.) ; Dominican Republic, Puerto Plata 

 (Darlington, in M.C.Z. and U.S.N.M.), Coustanza (Darlington, in M.C.Z.), 

 Sdnchez (Darlington, in M.C.Z. and U.S.N.M.), San Josf'' de las Matas 

 (Darlington, in M.C.Z. aud U.S.N.M.). 



Puerto Rico: Jaynya (Oakley, in U.S.N.M.). 



St. Ci-oix: (Blackwelder station 841). 



Guadeloupe: Basse Terre (Blackwelder station 79B). 



St. Lucia: (Blackwelder station 209A). 



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

 eron's collection, 16 examples in the United States National Museum, 

 19 from the Museum of Comparative Zoology, and 12 collected by 

 me in 1935-37. Two additional specimens are in Dr. Cameron's col- 

 lection under this name but labeled also as cotypes of hicoloricornis 

 Bierig (MS. name). 



Remarks. — I did not examine the two "cotypes" from Cuba. The 

 above description was taken entirely from the specimens in the 

 United States National Museum. Dr. Cameron did not mention the 

 folds of the fourth and fifth sternites, and I failed to examine the 

 type for this character. If the}^ are not present, then my specimens 

 may be a distinct species. The shape of the head and the male char- 

 acters place this species in the subgenus Scopaeus s. str.
