MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 437 



indistinct ground sculpture intermixed. Abdomen finely and densely 

 submuricately punctate ; with dense but not very distinct ground sculp- 

 ture. Male, eighth sternite with triangular emargination as deep as 

 wide, with inner edges beveled and outer angles rounded. Female, 

 eighth sternite rounded. Length, 314 to 4^/^ mm. 



Type locality. — Jamaica, Port Royal. 



Types. — In Dr. Cameron's collection. 



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



Cuba: (Koch, 1936), Playa de Marianao (Bierig, 1934; U.S.N.M.). 

 Jamaica: (Bierig, 1934; Koch, 1936), Port Royal (Cameron, 1922). 

 Puerto Rico: San Juan ( Blacltwelder station 43A). 

 St. Croix: (Blackwelder stations 326, 329, 344). 

 St. Kitts: (Blackwelder station 307). 

 Antigua: (Blackwelder station 276). 

 Montserrat: (Blackwelder station 269). 

 Guadeloupe: Basse Terre (Blackwelder station 77A). 

 Dominica: (Blackwelder station 240V^B). 



Specimens excmiined. — I have seen 13 examples in Dr. Cameron's 

 collection and 22 collected by me during 1935-37. 



Remarks. — This species is very similar to sericcus Holme, aguayoi 

 Bierig, and pruinosus Erichson. Whether these represent species or 

 A^arieties (subspecies) I am not in a position to decide. The length of 

 the antennae, the punctation of the head, and the anterior angles of 

 the pronotum are so variable in both the West Indian examples and in 

 sericeus from the Eastern Hemisphere as well as aquayoi from eastern 

 North America that they will not serve to distinguish them. For the 

 present it is best to retain subtilis as a valid species, at least until 

 adequate series of all these species can be studied. This species be- 

 longs in the subgenus Remus Holme. 



I have found it under seaweed and drift on sandy beaches. 



2. CAFIUS CARIBEANUS Bierig 



Callus coralUcola var. caribeanus Bierig, 1934a, pp. 67, 68, fig. 2. — Koch, 1936, 

 p. 175, 176, 186. 



Description. — Black, the abdomen more or less castaneous. Head 

 straight or slightly rotund behind the eyes with the angles roimded ; 

 the eyes separated from base by about their length; with a fine im- 

 pressed median line from between the eyes to front margin; with 

 coarse, somewhat impressed and umbilicate punctures scattered rathei^ 

 densely except along middle and in front; with distinct strigulose 

 ground sculpture. Pronotum about one-fifth longer than wide, widest 

 at anterior third, feebly narrowed to basal third and thence straight 

 to prominent basal angles; with smooth midline marked by two con- 

 fused rows of moderate punctures, and with rather densely but ir- 

 regularly scattered punctures laterally with more or less smooth band
