A NEW VARIETY OF CICADA RESEMBLING 

 C. DORSATA. 



By Wm. T. Davis. 



New Brighton, Staten Island, N. Y. 



Thomas Say states that his Cicada dorsata was found near the 

 Konza village in Missouri, which was located on the Kansas river 

 in what is now the eastern part of the present state of Kansas. Say's 

 original description is in part as follows : " Head and thorax varied 

 with greenish-yellow and black; scutel blackish-chestnut, the W and 

 X marks greenish-yellow, lateral lines of the W white near the 

 thorax, a white line from the humerus is interrupted by the anterior 

 lines of the X, and also in the middle between these two lines, a 

 white spot between the two lateral lines of the X: tergum black, a 

 dorsal line of white spots and a marginal line of white spots which 

 are continued over the terminal segment, the lateral spot of the first 

 and second segments is very much dilated and confluent, that of the 

 third segment is much elongated and attenuated towards the back, a 

 white oblique spot on the first segment each side of the dorsal line; 

 all these white marks are pruinose. Length two inches to the tip of 

 the hemelytra." 



Some individuals are a little larger than this. We figure a male 

 from Chetopa, southeastern Kansas. Specimens have been exam- 

 ined from
