Blephaeocerid.®.

Zool. Anz. iv. pp. 499-502. 
The larva of Paltostoma agrees with that of Culex in breathing 
through a terminal pair of air- tubes ; and it possesses five urinary 
vessels, as in the Culicidm and Psychoda, Some larvae deceptively like 
those of the Blcpharoceridcc produced a gnat closely resembling Psychoda, 
This, with Psychoda, and the Culicidcc and Blcpharoceridcc, may form a 
specialjgroup of Diptera under the name Pentanephria.
