MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 509 



moderate punctures at the sides; with minute punctukie throughout 

 and fine strigulose ground sculpture. Pronotmn about one-half 

 longer than wide, Avidest at anterior third ; sides scarcely emarginate 

 behind; with two pairs of large discal punctures; midline briefly 

 canaliculate at base; with punctulae and sculpture as on head. 

 Elytra almost impunctate except at margins; somewhat coriaceous 

 but not otherwise sculptured. Abdomen almost impunctate except 

 for marginal setigerous punctures; with fine but distinct transverse 

 strigulose ground sculpture. Length, 6 to 6I/2 nim. 



Type locality. — Haiti, La Visite and Adcinity in the La Selle Range ; 

 elevation 5,000 to 7,000 feet. . 



Types. — Holotype and two paratypes in the Museum of Com- 

 parative Zoology; two paratypes in the United States National 

 Museum (No. 52528); collected on September 16-23, 1934, by Dr. 

 P. J. Darlington. (Paratypes from other Haitian localities as 

 below.) 



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



Cuba: Mountains north of Imias, Oriente (Darlington, in M.C.Z. and U.S.N.M.). 

 Hispaniola: Haiti, La Visits (Darlington, in M.C.Z. and U.S.N.M.), Furcy 



(Mann, in M.C.Z.), Roche Croix, Massif de La Hotte (Darlington, in M.C.Z. 



and U.S.N.M.). 



Specimens examined. — I have seen only the five types and the two 

 specimens from Cuba. 



Remarks. — There is some variation in the extent of the dark areas 

 of the abdomen, but the species can be recognized by its coloring and 

 the presence of the marginal ridges behind the eyes. 



I have received no record of its habits. 



Subfamily Tachyporinae 



This subfamily is represented in the collections before me by rela- 

 tively few species but by a very large number of individuals. Cer- 

 tain species of Coproporus are exceedingly abundant on some of the 

 southern islands, as well as in South and Central America. 



The group is not distinguished by any outstanding morphological 

 feature but rather by a combination of characters as used in the key. 

 Its members are usually readily recognizable by their general 

 appearance.
