Length of body, 25 mm. 31 mm. 



Length of pronotum, 6 " 7.2 " 



Length of tegmen, 27 " 25.5 " 



Length of caudal femur, L5.2 '' 18.2 " 



As I imagine Scudder's measurements, in his Revision of the Me- 

 lanopH, were taken from the specimen of keeleri there figured, their 

 small size is due to the fact the individual was from North Carolina. 



On the evidence of the material examined I am compelled to con- 

 sider Melanoplus deletor Scudder a synonym of Melanoplus keeleri 

 (Thomas). 



Paroxya atlantioa Scudder. 



A series of forty- five specimens represent this species, the several 

 localities being as follows: Pablo Beach, August 11, 12 and 13, twenty- 

 seven males, seven females; Gainesville, August 16 and 17, six males, 

 two females ; Cedar Keys, August 15, one male, two females. At Pablo 

 Beach the species was numerous among the tall grasses growing in 

 extensive wet areas, drains and in the smaller marshy spots in the 

 palmetto scrub, while at Gainesville the vicinity of a sink-hole in the 

 pine woods was frequented. Salt marsh was the environment in 

 which it was found at Cedar Keys. 



There is an appreciable variation in size in the Pablo Beach series, 

 particularly in the males. In color there is considerable variation in 

 the degree of purity of the yellow color. The two Gainesville females 

 are deeper in color than the average Pablo Beach individuals, while 

 both Cedar Keys females and one of two from Gainesville have the 

 dorsum of the head, pronotum, caudal femora, face, limbs and ventral 

 portion of the lateral lobes of the pronotum washed with, wine purple. 

 Paroxya floridiana (Thomas). 



At Pablo Beach this species was found frequenting tall grass growing 

 along a railroad drain, four males and two females being taken on 

 August 11. At Gainesville a single female was taken near a sink-hole 

 in undergrowth in pine woods on August 16. 



When compared with material from the northern portion of the 

 range of the species the Florida specimens are seen to be much larger, 

 and a comparison of material shows a steady increase in size as one 

 proceeds southward. In view of this fact comparative measurements 

 of specimens from several points within the range of the species are 

 here given. No effort has been made in the selection of specimens for 

 measurement to pick only those supporting the view expressed above, 

 as on the contrary the individuals used have been taken haphazard
