characterizes the tri-fasciate markings; these spots if present at all, 

 are almost never so pronounced in true atlantica. 



The series from the southern Keys are readily separable from 

 specimens of atlantica from the mainland and Cape Florida on Key 

 Biscayne, although their characters are practically intangible and 

 exceedingly difficult to express without exaggeration. 



Caudell's record of Melanoplus paroxyoides from Miami 39 belongs 

 to Paroxya atlantica; the paratypes from Tallahassee, Fla., should 

 doubtless be referred to the same form. 



This geographic race is usually found fairly abundant in the low 



halophytic vegetation growing on the otherwise almost bare coquina 



rock of the Keys and also in the tangled growth along the edge of 



the scrub.

This series shows that while there is considerable variation in size, 

 both geographic and individual, in the present species, the characters 

 originally given hold true in the series of seventy specimens now 

 available for study. As previously pointed out by us, 40 male speci- 

 mens from Tampa are not quite typical in the form of the cerci, these 

 being less elongate and not as decidedly falcate as in individuals 

 from southern Florida, but in all other characters they are fully 

 representative of clara. It is possible that this species is a geographic 

 race of sphenarioides, but we have no positive evidence of this or 

 even of approach to that form except in the shortening of the distal 

 portion of the cerci in the Tampa specimens.
