green face. The striped face form retains that condition through

 condition without acquiring the barred face, but within a few 

 days after becoming adult, as the chitin thoroughly hardens the

 It is very probable that green face adult specimens from New

 adult coloration. 



Measurements (in millimeters) of a number of average pairs 

 from representative localities .are here presented. 



Normally this species has the ventro-external margin of the 

 caudal femora unspined, an occasional specimen, however, having
