turned distinctly mesad. The last ventral segment of the male is con- 

 siderably less than twice as wide as long, the lateral margins are strongly 

 sinuate, and the broad truncate apex is broadly and clearly incised. The 

 pygofers of the female have the margins regularly curving to the small 

 but stout median tooth. The last ventral segment of the female is 

 quite characteristic, the lateral margins being sinuate while the posterior 

 margin is deeply and angularly excavated over one-half the distance to 

 the base, the margins of the excavation being distinctly notched. The 

 ovipositor is short and stout, the teeth on the lateral pieces being quite 

 ro".nded and even, about a dozen on each side. 



Distribution: This species has been taken in the three west- 

 ern counties of Trego, Ellis and Russell. The latter two records 

 are those of the Kansas State Agricultural College. Van Duzee 

 records it from Colorado, Nevada, and California. Davis men- 

 tions New Mexico, Arizona and Montana as states where it 

 occurs. It is very evidently a western species which reaches 

 its eastern limits in Kansas. 



Remarks: There seems to be some doubt as to the proper 

 generic disposition of this species. Davis places it in the genus 

 Okanagana because the relative size of the marginal cells and 

 those of the median area of the fore wing is about the same 

 as in the members of that genus. On the other hand the color- 

 ing of the fore wings is that of the genus Tibicinoides as is 

 also the very conspicuous nodal furrow. 



Genus MELAMPSALTA Kol. 



These are very small cicadas. The tympanal coverings are 

 lacking, and the venation of the fore wings is very characteris- 

 tic in that the marginal cells are of about the same size or even 

 longer than the cells of the median area. 



The single member of the genus occurs in Kansas.
