the margins are slightly sinuate and the apex is broadly rounded. The 

 pygofers of the female bear a long median spine and the margins are 

 distinctly and obtusely ang-ulate. The last ventral segment of the female 

 is of about equal length throughout, the posterior margin bearing two 

 small lobes on either side of a small median triangular excavation. The 

 lateral pieces of the ovipositor bear rather weak teeth of which only two 

 or three on each side are prominent, the remaining four or five being 

 very indistinct. Cephalad of the teeth is a very weak ridge on each side. 



Distribution: The only record of the capture of this species 

 in Kansas comes from Chautauqua county. Van Duzee records 

 it from the following states : New Jersey, Pennsylvania, North 

 Carolina, Georgia, Florida, Mississippi, Louisiana and Texas. 

 Thus it would seem that Kansas forms the northwestern limit 

 of this species. 



Remarks: The males of this species seem to be much more 

 common than the females. Mr. Davis kindly loaned me one of 

 the latter and states that they are comparatively uncommon. 

 He says they occur most commonly in the pine barrens, "where 

 in June and July their songs constitute an almost continuous 

 performance." 



Genus Proarna Stal. 



The members of this genus are very small cicadas. The 

 tympanal coverings are very imperfect, leaving most of the 

 tympanal orifice exposed. The abdomen is not translucent and 

 the cross vein of the fore wings between Rs and R^ -• is very 

 characteristically perpendicular instead of oblique. The oper- 

 cula are small and do not approach each other very closely. 



A single member of the genus occurs in Kansas.

A very small pale green to straw-colored species. Specimens at hand 

 measure from 1 1 to 13 mm. 



Col<yr: Head greenish or straw-colored, with a more or less continuous 

 brownish transverse band between the eyes and extending backward 

 medially to enclose the ocelli. The antennal ledges also are usually some-

 angles darkened, and sometimes the grooves slightly darkened also. Some-
