MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 215 



Type locality. — Jamaica, between Mocho and Catadupa, in south- 

 ern St. James Parish, 



ry/jg.s'.— Holotype and two paratypes, U.S.N.M. No. 52387, col- 

 lected by Chapin and Blackwelder in 1935-37; two paratypes col- 

 lected by H. G. Hubbard; and one paratype collected by Harold 

 Morrison on September 12, 1917. 



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



Jamaica: (Hubbai'd, in U.S.N.M.), Sharps Grove near Chapelton (Morrison, in 

 U.S.N.M.), Mocho, in St. James Parish (Blackwelder stations 16, 406), Man- 

 chioueal (Blackwelder station 364), 



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



Remarks. — I am unable to distinguish sexes among these six speci- 

 mens. The type and one other have the ninth sternite narrowly 

 excised at apex, but all the others have this segment so far retracted 

 that it is invisible. 



The type and two others collected by me were all taken by sweep- 

 ing low herbage along the road. On each occasion further collecting 

 failed to produce more specimens.

Description. — Piceous. Head not distinctly biimpressed but w4th 

 midline feebly raised; without smooth areas; labrum broadly 

 rounded; punctures rather coarse and deep, regular, generally sepa- 

 rated by about half their diameter; intervals moderately convex, 

 with a faint alutaceous luster; pubescence distinct. Pronotum one- 

 third longer than wide, widest at middle, scarcely narrowed in front, 

 slightly but emarginately narrowed behind; punctures coarse and 

 deep but very dense, separated by less than half their diameter by 

 convex intervals; without ground sculpture or pubescence. Elytra 

 about one-half wider than pronotum, nearly one-sixth longer than 

 wide; humeral callus not prominent; punctation similar to that of 

 pronotum but a little coarser, sparser, and less abrupt, intervals not 

 so convex; without ground sculpture or pubescence. Abdomen not 

 margined ; with same type of punctures as elytra but less coarse and 

 less dense; with distinct ground sculpture on seventh and eighth 

 tergites; pubescence very short. Tarsi with fourth segment strongly 

 bilobed. Male, sixth sternite slightly flattened at middle posteriorly 

 and with an indefinite area of minute sculpture and denser pubes-
