OSBORN AND. BALL — THE GENUS PEDIOPSIS. I 23 



on the upper angles of the front. Pronotum with an elongate spot 

 behind either eye, black, scutellum with the basal angles, two spots on 

 the disc and a median longitudinal line sometimes interru[)ted, black, 

 propleura with a distinct black spot in both sexes. 



Habitat, Arizona. No new material in this distinct little .species 

 has been obtained, indicating that it is a more distinctly southern or 

 western form. 



The females are lighter colored than the males and in the lighter 

 ones the spots are reduced in size. 



Pediopsis reversalis O. & B. 



Dav. Acad. Nat. Sci., \'II., )). 69 (January, i8g8). 



Small, compact, light green, male with two heavy black bands on 

 face, sometimes reduced to three spots. Length, 9 4.50 mm.; c?', 

 4 mm.; width, scarcely more than i mm. 



Vertex slightly more roundingly obtuse than in punctifroiis. Pro- 

 notum nearly smooth, rugae fine, obscure, the anterior pits obsolete ; 

 color, light green, the males with the elytra scarcely if at all darker 

 than in the females ; male face in the darker specimens with two broad 

 black bands, one on the superior margin not quite reaching the eyes, 

 and another between the antennal pits; in lighter specimens these 

 bands may be reduced to three small spots, one at the apex and one 

 on each superior angle of the front, "propleura with a round black spot 

 in the male. 



Habitat, Iowa and New York. Occurs on the narrow-leaved willows. 



Its small size and light green color, even in the males, will serve to 

 distinguish it from all the other green species without reference to the 

 marking on the face of the males. 



Note. — Pediopsis nubila V. D.,from California, seems to be more closely 

 related to the genus Bythoscopus in head characters than to this genus, and 

 has been purposely omitted from the synopsis. The reticulate venation 

 renders it a very distinct form in either genus.
