 Newfoundland ; Nova Scotia ; United States ; Mexico ; W. Indies. The 

 larval habits of the European O. bicolor (coccinea Meig.) are known ; the 

 larva is parasitic in the body of Pentatoma grisea. The larva of a second 

 species was found in the body of a Cassida (Schiner). 



NOTE. Robineau Desvoidy's genus Parthenia was separated from 

 Ocyptera on very insufficient grounds, and I have not revived it.

The larvae have been found parasitic only in the adults of 

 beetles.

 flexure of the fourth longitudinal, which is arcuate ; apical cell 

 closed and petiolate ; antennae short, third joint only once or
