1878. (?) 



A western species which is quite distinct from all other members 

 of the genus, although resembling odo-lineata Say in general appear- 

 ance. However, the anterior margin of the vertex is much thicker 

 and more broadly rounding than in odo-lineata Say and the elytra 

 is never reticulate. The female segment is much the same in both 

 species. It is a bright yellow to green species, sometimes nearly 

 white. Dried specimens appear yellow. 



Its distribution includes the Rocky Mountain States westward to 

 the Pacific and north into Canada. 



9. GYPONA NIXABUNDA, new species. 



Vertex nearly one-half as long as width between the eyes, anterior 

 margin thin, prominently depressed beneath. Striations on vertex 

 oblique, transverse on pronotum. Ocelli comparatively small and 

 nearer the median line of vertex than eyes and midway between 

 anterior and posterior borders. A black spot on the pronotum 

 behind each eye. Scutellum about equal to pronotum in length. 

 Base of clavus black. Female segment with two small lobes at the 

 middle and shallowly sinuate on either side. Size, female, 10 

 mm. long. 



Color, female, entirely green or yellowish green, with only other 

 color markings being the spots on pronotum and base of clavus 

 darkened. Female same as male with dorsal side of abdomen more 

 or less darkened in bands and apex of elytra smoky. Elytra trans- 

 parent in both sexes in dried specimens. Veins of the hind wings 

 of the male black.
