Type— Cnt. No. 20276, U.S.N.M. 



One female taken by Prof. T. D. A. Cockerell on Solidago, where 

 it had been caught by a Phymata, which is mounted on the same pin. 

 Easily recognized by its intensely black clypeus, short antennae, and 

 milky white wings.

The badly mutilated male type of this species is in the United 

 States National Museum. In color, pattern of legs, and color of wings 

 it agrees with nigriclypealis Cushman, but differs in having the sculp- 

 ture of head and thorax finer; the antennae long; the orbits broadly
