102 THE CANADIAN ENTOMOLOGIST. 



Variety G. Wings red ; inside of hind femora brown, lower sulcus green; 



hind tibiae yellowish red. 

 " H. Wings red ; inside of hind femora greenish blue ; hind tibiae 

 yellow ( CE. discoidea). 



Variety " D " I have frequently seen mated, but never with any other 

 variety. This, then, may prove a distinct species, which point another 

 season's observation may determine. The other varieties mate indis- 

 criminately and assume the imago form at the same time. Probably a 

 close search would reveal other varieties not enumerated above. 



A similar instance of variation in color is afforded by another Nebraska 

 species, viz., CEdipoda cincta Thos. 



This species appeared sparingly last August. Its season was of short 

 duration. It is of medium size and has spotted elytra similar to CE. 

 corallipes. In Mr. Thomas' description of the % the wings are said to be 

 " transparent, base greenish yellow, a narrow fuliginous band across the 

 middle, apex pellucid with a few fuscous dots." This description applies 

 very well to perhaps half the $ specimens obtained here ; although the 

 band can hardly be called " narrow " as compared with our other 

 CEdipodas. But specimens with the base of the wings red were quite as 

 frequently seen, both males and females. The two varieties appeared at 

 the same time, were found in company and disappeared together. Other 

 than the color of the wings, there is no perceptible difference between 

 them. The $ , not described by Mr. Thomas, is smaller and darker than 

 the $ . It has several large fuscous spots at tip of wings ; the inside of 

 hind femora and hind tibiae are of a more brilliant blue, and the whole 

 upper side of the abdomen has, in life, the same beautiful color. 



The species, as taken here, differs in several particulars from Mr. 

 Thomas' description of ciucta,hut is said by that gentleman to be identical. 



The red winged var. may therefore be known as CEdipoda cincta var. 

 umbrator. . The measurements of both varieties are as follows : 



Female — Length, 1.25 inches ; elytra, 1.20 inches; hind femora, .65 in. 

 Male — Length, .95 inches ; elytra, .90 inches ; hind femora, .55 inches. 



From the above notes it will be seen that color can not always be 

 depended upon as a specific character in our GEdipodini. Undoubtedly 

 the present number of supposed species could be greatly reduced by 

 careful comparisons instituted on the field of collection.
