MONOGRAPH OF WEST INDIAN STAPHYLINIDAE 267 



indistinct tuberculi as on pronotum; without distinct ground sculp- 

 ture. Ahdomen with minute punctures obscured by irregular sculp- 

 ture. Male^ unknown. Female, sternites not modified. Length, 

 3 mm. 



Type locality. — Trinidad, 11 miles north of Arima, elevation 1,800 

 feet. 



Types. — Holotype, female, in the Museum of Compaiative Zoology, 

 collected on March 28, 1935, by N. A. Weber. 



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



Trinidad: Arima (Weber, in M.C.Z.). 



Specimens examined. — I have seen only the unique type. 



Remurks. — This species is unique in the coloring of the elytra but 

 is immediately distinguished from all other West Indian species by 

 possessing tuberculi on the pronotum and elytra instead of umbilicate 

 punctures. It belongs in the subgenus Caloderma, of which it is our 

 only respesentative. 



I have received no record of its habits.
