March, I9i6.] DaVIS : CiCADAS FROM THE UnITED StATES. 45 



lection of the University of Kansas. We think that the species repre- 

 sented by this extensive material is Say's long lost Cicada aurifcra. 

 It is of the right size; fresh specimens are pubescent; beneath hairy; 

 the first and second cross veins conspicuously blackened, almost spot- 

 like ; the pronotum is almost wholly green and " little varied with 

 black " ; the mesonotum is black with the '' usual tectaceous lines " ; 

 the tergum is black covered with golden hair in fresh specimens; be- 

 neath pruinose, and lastly most of the insects came from near the 

 type locality, for Franklin Co., Kansas is not far from the site of the 

 Konza Indian village visited by Thomas Say. 



Uhler states in his Preliminary Survey of the Cicadidse of the 

 United States, Antilles and Mexico, Transactions Maryland Acad- 

 emy of Science, 1892, that Cicada aurifcra was known only from 

 the original description and adds: " It seems to be a pale variety of C. 

 canicnlaris, which inhabits that state, but the size given is smaller 

 than that of any specimens thus far brought to our notice." He was 

 nearly correct in this, for Cicada aurifera is related to Cicada canicn- 

 laris Harris, but still more closely to Cicada davisi Smith and Gross- 

 beck. We figure a male Cicada aurifcra from Franklin Co., Kansas, 

 a male Cicada canicnlaris from Lake Mahopac, New York, and a male 

 Cicada davisi from Manson, N. C. It will be seen that in canicnlaris 

 the eyes are not set as obliquely as they are in davisi, and in aurifcra 

 they are still less prominent. In examples of the same expanse 

 of wing, aurifcra measures less across the head than does davisi. 

 The uncus when seen from behind is broader in canicnlaris than 

 in davisi and aurifera, but in aurifera the tip is more gradually 

 rounded in either of the other two. Beneath the opercula are 

 about of the same shape in all three species. The color pattern 

 of the three species is similar. The pronotum is all green in 

 aurifera with the exception of the triangular black spot contiguous 

 to the anterior margin and enclosing a wedge-shaped spot of 

 green. In davisi the pronotum is usually more black, but the hind 

 margin or collar is green. In canicnlaris the collar is green with its 

 front margin often edged with black. The mesonotum is blacker in 

 canicnlaris than in either of the other two; the usual W-ma,rk and 

 elevated X of a lighter color, is present in all three. The tergum is 

 l)lack in the three species, but in aurifcra the hind margins of the 

 segments are often edged with testaceous. The wings of canicnlaris
