NO. 2289. LEAFHOPPERS OF THE GENUS GYPON A— GIBSON. 91 



ticulations of the wings of geminata Osborn are confined to the apical 

 portion. It is a bright green species, becoming yellow in dried 

 specimens. 



The only two specimens that I have examined are paratypes from 

 Professor Osborn's collection. They were captured from pine at 

 Cold Springs Harbor, New York, 1904. 



5. GYPONA RAMOSA Eirkaldy. 



Gypona ramosa Kirkaldy, Hawaiian Sugar Planter's Assoc, Bull. No. 4, p. 60, 

 1907. 



This southwestern species is conspicuous among other members 

 of the genus because of its very thin or foliaceous anterior margin of 

 the vertex, which is tinged with black. It is bright yellow or yellowish 

 green, but sometimes nearly white. The elytra is heavily reticulate, 

 having nearly a rugose appearance. There are two black dots near 

 the anterior margin of the pronotum, one behind each eye. Speci- 

 mens are entirely light beneath. 



The only records of this species in the United States come from 

 southeastern Arizona. 



6. GYPONA TENELLA Sp&ngber£. 



Gypona teiulla SpAngberg, K. Svenska Vet. Akad. Handl., vol. 5, No. Z, p. 34, 



1878. 



The long, produced, and rather acutely pointed vertex separates 

 this from all the other green species. Otherwise in general appearance 

 it resembles angulafa Spangberg. It is one of the smallest members 

 of the genus, the female measuring less than 8 mm. long. 



The only specimens examined are from Texas, however it is also 

 known to occur in Florida. 



7. GYPONA DICTITORIA. new species. 



Vertex short, less than one-half the length of pronotum; anterior 

 margin comparatively thin and slightly produced at the middle. 

 Vertex depressed behind apex. Ocelli very lai^e and clear, placed 

 midway between median line of vertex and eyes. A small dark spot 

 behind each ocellus on posterior border of vertex. Pronotum not 

 much wider than head, striations transverse. Elytra opaque with 

 base of clavus unmarked, with appendix. Female segement pro- 

 duced at the middle with very deep sinuations on each side. Size, 

 female 10.5-11 mm. long. Very robust. 



Color, a decidedly green species, sometimes with inner margins of 

 elytra mottled with brown, more often without any dark markings. 



Type. — Female, Reddington, Arizona, collected by Dr. W. Barnes. 

 (Collection of U. S. National Museum.) Cat. No. 21882.
