Types.— lloloiy^Q, female, U. S. N. M. No. 52466, collected on ''11.6" 

 by August Busck. 



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



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



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



Remarks. — This species differs from lustraUs in having only four 

 punctures in the pronotal series, and from the other West Indian 

 species in its piceous color and the shape of the pronotum. 



I have no record of its habits.
