This species was described by Renter as a variety of valid us but 

 it proves on close examination to be a distinct species. It may be dis- 

 tinguished by the well defined and punctate calli, the rich brownish 

 color with red cuneus, more or less oval-shaped fuscous spot at apex 

 of membrane, and by the structure of the genital claspers (PI. X). 

 Cuneatus is more robust than nubilus, particularly the males, which 

 have shorter hemelytra in proportion to the body, being more like the 

 females in form. 



Mr. McAtee found this species developing on A! mis ntgosa which 

 is probably the preferred host plant. In New York the writer took 

 a teneral specimen on Piiiiis sfrobus which had undoubtedly developed 

 on that tree, and the species has also been collected on the same tree 

 in Connecticut. Judging by the habits of related species, the writer 

 would not be surprised to learn that cuneatus is predaceous upon the 

 alder blight aphid, PeiitpJiigus fcsscliafus Fitch, and the pine l)ark 

 aphid, Chermes pinicorticis Fitch. 



Renter's chirotype for the manuscript name "Caniptobrocliis 

 poccUus" is in the U. S. National Musetmi collection, — $ Washington, 

 D. C. (O. Heidemann). Uhler's manuscript name for the species was 

 "Camptobrochis crassicoruis," three specimens having been noted with 

 this label.
