HEMIPTERA. VAN DUZEE. 3 
Wright of San Diego, who has turned over to me many interesting 
emiptera and has given me valuable information respecting col- 
lecting grounds, and to Mr. J. L. Rose of Alpine, who has very 
kindly opened his Alpine home to me, where much of my back- 
country collecting has been done and which has proven an excel- 
lent place for Hemiptera work. 
_ This paper enumerates 392 species or distinct varieties, of 
which 52 are new, and four new genera are characterized: Pycno- 
coris, Platycixius, Oeclidius and Rhynchopteryx.

eriorly with ferruginous, the surface on either side covered with 
matted pale hairs; disk marked with irregular oblique blackish

& pair of roundish black spots. Anterior half of the narrowly 
rounded lateral margins white, posterior half black. Scutellum 
Shorter and broader than in proteus, grey, distinctly punctured with 
lack and varied with blackish ares; on either side of the base is a
