A new Variety of Rihana (Cicada) sayi Grossbeck 
(Hemip.). 
By Wo. T. Davis, Staten Island, New York. 
Through the courtesy of Mr. J. Chester Bradley, of Cornell 
University, I have examined a number of Cicadas from 
Georgia, collected principally by him. Among them are 18 
examples of Rihana sayi Grossbeck, described in ENToMo- 
LocicaL News for April, 1907. Ten of these are of the type 
usually found in the Middle States, namely with the lateral 
and posterior margins of the pronotum nearly all black with a 
green spot on each side of the center of the latter. In the au- 
thor’s collection there are 86 examples from New York, New 
Jersey, Ohio, North Carolina and Rabun Co., Ga., that follow 
this pattern quite closely; in several, however, the posterior 
margin of the pronotum, or collar, is wholly black. 
There is a southern race more green in color than typical 
Rihana sayi which may be called 
australis n. var. 
In this the pronotum is nearly all green, the two black triangular 
spots near the anterior margin are reduced, the collar is green, touched 
with black at the lateral angles, and is narrowly margined in front 
with the same color. There is also a black line in the center about I 
mm. broad. The mesonotum is green, fulvous and black. 
Typical examples are from Albany, September, 1910; Bain- 
bridge, July 1909, September, 1910 and Spring Creek, Deca- 
tur Co., June, 1911; all collected by Mr. Bradley in Southern 
Georgia. 
Fresh specimens of this variety are quite beautiful in color. 
Two examples from Atlanta and one from Austell, Ga., ap- 
proach the variety, but lack the green on the thorax. One of 
the 86 specimens mentioned above, and collected on Staten 
Island, N. Y., has the collar nearly all green, but lacks the 
green on the thorax. 
By way of recording distribution it may be well to state that 
Mr. Bradley’s collection contains two Rihana davisi Grossbeck, 
from Atlanta, Ga., September, 1909, and August, 1910, and 
two Rihana engelhardti Davis, from Atlanta, Ga., July, rgro.
