(e 1 and e 2 ) is diagnostically worthless; such variation as is noted in 

 tegminal markings is found everywhere in the eastern series before us 

 which belong unquestionably to the same species; it is impossible to 

 separate Scudder's series of texanus from the present insect by means 

 of tegminal contour, while the "sharp" and "not very sharp" lateral 

 carinse of the pronotum are intangible. The g 2 portion of the key 

 serves fully as well to separate phoenicopterus from haldemanii. 



Scarcely any geographic variation in size is found in the present 

 species over that portion of its range here considered; however, 

 material from the low-land portions of Georgia, from Florida and 

 Texas, shows a somewhat greater robustness of the caudal femora 

 accompanied by an appreciable increase in the lamellation of the 

 ventral margins of the same. The tegminal length in the present 

 series is variable irrespective of geographic distribution, extremes 

 of the present series measure as follows; males 27.5-32 mm., females 

 33-43 mm. The specimens from Texas are as large as the largest 

 specimens here recorded and have tegmina which, in the majority 

 of such specimens before us, very slightly exceed in length the maxi- 

 mum in the present series. 



In the present series are five males and two females with head, 

 pronotum and caudal femora greenish. Specimens from the low- 

 land of Georgia and from Florida are somewhat more brilliantly 

 colored and show a greater diversity of coloration than do those 

 which compose the remainder of the series; among these are several 

 females and one male with head, pronotum and caudal femora paler 

 than usual and almost immaculate, while the tegminal markings are 

 considerably reduced in number. A female from Augusta, Georgia, 

 is nearly immaculate, but darker in coloration than these specimens. 



The present insect appears adult in the early spring, and by the 

 first of August few survivors remain. South of the northern portion 

 of Florida the species is known from but four specimens, two males 

 captured at Lakeland, a female from Cleveland and an immature 

 female from Southside, Miami. 52

 caudal femora and the increase in the lamellation of the ventral margins of the 

 same.
