This genus, peculiar to tropical and subtropical America, is repre- 
sented in Brazil by seven known species, of which four have been 
previously recorded. Of the three here first listed from Brazil, two 
are described as new. In addition, Scolopocryptops aurantiaca and S. 
viridis Gervais (Insect. Aptéres, 4) are probably based upon members 
of the present genus; but there is nothing in the original descriptions 
to make precise identification possible, and the names must be dropped 
until the types are examined, if they now be in existence.
