MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 507 



middle posteriorly; antennal grooves completely obsolete, ocular 

 grooves very irregular but distinct; underside margined with a dis- 

 tinct ridge and a densely sculptured submarginal longitudinal de- 

 pression; with a few large setigerous punctures laterally, but vertex 

 impunctate; with fine longitudinal strigulae. Pronotum two-fifths 

 longer than wide; with a single pair of large discal punctures, and 

 two or three lateral punctures; midline vaguely canaliculate posteri- 

 orly; with strigulae not always longitudinal. Elytra with surface 

 very irregular, with a few distinguishable punctures; but without 

 ground sculpture. Abdomen with a very few setigerous punctures; 

 without ground sculpture. Length, 5 mm. 



Type locality. — Colombia. 



Types. — Either in the Hope Museum, Oxford, or the Zoologische 

 Museum, Berlin. 



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



St. Vincent: (British Museum). 



South America: Colombia (Ericlison, 1839b; Bernhauer and Schubert, 1914; 



Sliarp, 1885), Brazii. (Sharp, 1876; 1885). 

 Central America: Guatemala, Nicaragua (Sharp, 1885; British Museum). 



Specimens examined. — I have seen only the two West Indian speci- 

 mens examined in the British Museum, besides the series from Cen- 

 tral America. One of the former was borrowed for further study. 



Remarks. — The West Indian examples seem to be the same as the 

 Central American ones. The distinguishing feature (at least of the 

 West Indian examples) is the strong margining of the underside of 

 the head. I am not certain whether this is equally true of the Central 

 and South American ones. 



One of the West Indian examples in the British Museum is labeled 

 "Apr. 29. lot 14. under bark. 800 ft. open field."
