hemelytra two and a quarter millims. Length of cephalic 

 stylus scant two millims. 



Only males have thus far been examined. This insect 

 closely resembles some of the black forms of the Phry- 

 ganid genus Leptocerus Leach, with which it might 

 readily be confused, but the curved stylus projecting from 

 the head will at once show the hemipterist that its affini- 

 ties are with the homopterous genus /Scolojys Germ, next 

 to which it should be placed in a natural arrangement. 



It was captured in Los Angeles, County, Cal. by Mr. 

 D. H. Coquillett, and should be placed to the credit of the 

 Division of Entomology of the U. S. Bureau of Agriculture.
