Neoccelidia Candida Van D., Cat. Hemip. N. A., p. 690, 1917. 



Form: Stout and robust. Length, 4.25 to 4.5 mm. Vertex a little 

 wider than long, bluntly oval apically, disc convex, rounding to the tumid 

 front. Pronotum shorter than the vertex, over three times as wide as 

 long, anterior and posterior margins about parallel, humeral margins 

 long and rounding with the shorter lateral margins. Elytra short but 

 exceeding abdomen, venation distinct. 



Color: Whitish, sometimes tinged with pale green. Vertex with black 

 apical spot, ocelli and sometimes a pair of spots on disc, brown. Pro- 

 notum and scutellum unmarked except for brownish impressed line of 

 the latter. Elytra milky-white, nervures pale brown, apical cells some- 

 times brownish. Face pale, unmarked. 



External genitalia: Female, last ventral segment three times as long 

 as the preceding, curved around the pygofers, posterior margin slightly 

 medially produced; pygofers broad, nearly equalling the ovipositor, 

 sparsely spined. Male, valve as broad basally as last ventral segment, 

 longer than broad, apex acute, nearly equalling pygofers, with two round 

 black spots on disc. 



Distribution: Not yet reported from Kansas but should 

 occur in the western portion of the state. 



Hosts: Doctor Ball informs me that Atriplex canescens is 

 the host plant of this species. 



Genus CICADULA Zett. 



In general the members of this genus are rather small and 

 elongate. The vertex is longer on the middle than next the 

 eye, but not strongly produced. The pronotum is short, the 

 anterior margin more or less convex, the posterior margin 

 slightly concave. The elytra are long, exceeding the abdomen, 

 overlapping apically, with a distinct appendix, and with the 

 inner sector not forked, there being only two anteapical cells. 

 The wings have three apical cells, thus differing from the 

 wings of the two following genera where there are but two 

 apical cells. 



Four species and a variety of this genus have been taken in 

 Kansas.
