MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 219 



behind; with coarse and deep punctures generally separated by less 

 than half their diameter by convex intervals ; without ground sculp- 

 ture; pubescence very short but distinct. Elytra one-half wider than 

 pronoturn, one-seventh longer than wide; with humeral callus scarcely 

 elevated and without impressions; punctures less abrupt than on 

 pronoturn, appearing a little more separate, intervals less convex; 

 without ground sculpture; pubescence short but distinct. Abdomen 

 not margined; with punctures similar to elytra but smaller, sparser 

 apically, very much finer on eighth tergite which has distinct scaly 

 ground sculpture. Tarsus with fourth segment bilobed. Male., sixth 

 sternite with posterior half at center flattened and with a whitish 

 spongy surface, seventh sternite with same on apical two-thirds, 

 feebly emarginate at center; eighth sternite with a narrow acuminate 

 excision extending through three-fourths of its length, rounded at 

 sides. Length, 5 mm. 



Type locality. — Trinidad, Department of Agriculture Grounds, 

 Port of Spain. 



Types.— Roloty^Q, male, U.S.N.M. No. 52386, collected by Harold 

 Morrison on November 23, 1918. 



Records. — The following is the only record known to me : 



Trinidad: Port of Spain (Morrison, in U.S.N.M.)- 



/Specirnsns examined. — I have seen only the unique type. 



Remarks. — This species is very similar to jugalis Erichson as I 

 have determined that species. This is distinguished, however, besides 

 the character given in the key, by the much deeper and narrower 

 excision of the eighth sternite in the males. 



I have no record of its habits.

 their diameter; without ground sculpture; pubescence short. Elytra 

 three-eighths wider than pronotum, one-eleventh longer than broad; 

 humeral callus scarcely evident; punctures similar to pronotal but 

 intervals a little less convex; no ground sculpture; pubescence a little

 coarsely or closely, intervals flat; without ground sculpture except a
