DIRAPHIA QUADRICORNIS Provancher. 

 Diraphia quadricornis Provancher '86: 306. 



This appears to be identical with Psylla galeaformis Patch, but 

 because of the uncertainty I am unwilUng to refer the latter to 

 this name. 



According to Provancher it was described as follows : 



Length 0.20 inch; color green with orange tinge; cephalic cones, legs, and antennae 

 slightly lighter; antennae green at base, then lighter, black at tip, almost as long as 

 body. Wings entirely hyaline, veins prominent. Metacoxal spurs large, acute. 

 Female abdomen large, stout, brownish at extremity. 



Cape Rouge, Ottawa. Common. 



DIRAPHIA SANGtnNEA Provancher. 

 Diraphia sanguinea Provancher '86: 307. 



This suggests Psylla cerasi Patch, and is perhaps identical with it. 



It was described by Provancher as follows : 



Length 0.13 inch; color reddish to black; three lobes of mesonotum blood-red; tip 

 of rostrum, abdominal segment margins and tarsal spines black. Head pale beneath, 

 red above. Wings hyaline, triangular terminal cell very long and narrow. Abdomen 

 striped red and black. Genital segment long, pointed, conical.
