Aptenopedes sphenarioides Scudder. 



This interesting species is represented in the material collected by a 

 series of eighty-six individuals. The localities represented are Pablo 

 Beach and Gainesville, the former by twenty-nine adult males, eleven 

 adult females, six male nymphs and eighteen female nymphs; the 

 latter by five adult males, one adult female, eleven male nymphs and 

 five female nymphs. At Pablo Beach it was taken August 11, 12 and 

 13, in dry palmetto scrub, undergrowth in open pine woods, in 

 grassland and in tall marsh grass. At Gainesville, on August 16 and 

 17, it was found chiefly in undergrowth in pine woods, the vicinity of a 

 sink-hole being inhabited by it. 



The nymphs represent two stages and show that the principal color 

 characters of the adults are indicated for a considerable time before 

 the individual is mature. 



The size of the adult specimens is quite uniform in the Pablo Beach 

 series, but the Gainesville males show a very appreciable amount of 

 variation, the extremes measuring 18 and 20.8 mm. in length of body. 



Aptenopedes aptera Scudder. 



A series of eighty-six specimens represent this interesting species. 

 Pablo Beach is represented by thirty-eight adult males, nineteen adult 

 females, four male nymphs and nine female nymphs taken August 11, 

 12 and 13. At this locality the species was found associated with A. 

 sphenarioides particularly in the palmetto scrub, and but slightly less 

 abundant than the latter species. At San Pablo, August 13, two males
