MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 333 



Specimens examined. — I have seen no examples of this species. 



l^emarhs. — The differences between this and trinitatimi are listed 

 under the latter species. Certain of the characters in the above descrip- 

 tion were taken from the figures given by Bierig. This species belongs 

 in the subgenus CryptohieUa as stated by Bierig, although his genotype 

 designation for it is not valid (see Blackwelder, 1939a). 



Recorded as found in accumulated seaweed. 



2. OCHTHEPHILUM TRINITATUM, new species 



Description. — Rufous, elytra piceous with apical margin testaceous. 

 Head narrowed in front of the eyes; eyes situated at middle of 

 length; coarsely and densely, almost umbiiicately punctate, sparser 

 in front; with rather indistinct ground sculpture throughout; basal 

 segment of antennae three-fourths as long as head, over twice as 

 long as distance between antennae ; antennal grooves distinct ; labrum 

 with distinct denticle at sides of a rounded median emargination; 

 neck half as wide as head. Pronotum with narrow smooth and 

 slightly elevated median band, not canaliculate at base; punctures 

 rather large, umbilicate, leaving smooth areas, without ground sculp- 

 ture. Elytra with coarse punctures, narrowly separated by convex 

 intervals, without trace of serial arrangement; intervals with very 

 indistinct ground sculpture. Male^ seventh stern ite with a very shal- 

 low but abrupt median emargination and the surface depressed pos- 

 teriorly before the emargination; eighth with an abrupt and deep 

 narrow emargination twice as deep as wide and gradually rounded 

 to apex. Female^ eighth sternite truncate. Lengtli, 5 mm. 



Type locality. — Trinidad, 3 miles northeast of St. Augustine on 

 the Tacarigua River, county of St. Georges, ward of Tacarigua, 



Types. — Holotype, female, and four paratypes, male, U.S.N.M. 

 No. 52540, collected by me on December 22, 1935; four paratypes in 

 the Museum of Comparative Zoology; one paratype in the British 

 Museum. 



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



Trinidad: Tacarigua (Blackwelder station 107C), St. Augustine (Withycombe, 

 in the British Museum; Darlington, in M.C.Z. and U.S.N.M.), Cedros 

 (Darlington, in M.C.Z. ). 



Specimens examined. — I have seen only the ten types. 



Remarks. — This species differs from atlanticii'm in the characters 

 used in the key, as well as the presence of denticles and an emargina- 

 tion on the labrum and the canalicuiate median pronotal band. It 

 belongs in the subgenus CryptohieUa. 



The type was found under moss on a rock.
