San Pablo. August 13, two males, three females, one nymph; Gaines- 

 ville, August 16, one male. At Pablo Beach the species was found in 

 palmetto scrub, in tall marsh grass and along a sparsely covered rail- 

 road embankment, while at San Pablo and Gainesville it was found in 

 the undergrowth in pine woods. 



In color the series exhibits a moderate amount of variation, chiefly 

 in the shade of the base color, although the dark maculations also vary 

 somewhat in extent and intensity in proportion to the depth of the 

 base color, being weaker in the individuals with an ochraceous base and 

 well marked in those with a brown general tint. The caudal tibise 

 are scarlet vermilion in all the adults and glaucous in the single nymph. 



The form of the male cerci is as variable in the present series as in 

 the one from south Florida previously studied by the authors,* and the 

 extremes in the series of eight males are well marked and a number of 

 intermediates are also present, the latter constituting the greater part 

 of the lot. The keeleri extreme with the slender elongate accessory 

 lobe is on the other hand replaced by one with the accessory lobe 

 almost absent, represented in fact by an angulation, while the other 

 specimens when arranged according to their cereal character form a 

 complete transition from one to the other. 



On examining the original references of keeleri and deletor it is evident 

 that the claim made by Scudder^ that keeleri is smaller than deletor 

 is refuted by the measurements originally given from typical material. 

 Thomas gives the measurements of keeleri, a female, as follows : Length 

 of body 1.12 inches (28.4 mm.), length of tegmen .88 (22.3 mm.), 

 length of caudal femur .70 (17.7 mm.) ; while Scudder gives the follow- 

 ing for deletor: Length of body, male 23.5 mm., female 30.5; length of 

 tegmen, male 21, female 22; length of caudal femur, male 14.5, female 

 16. It would appear from the records and evidence of material that 

 this species is small toward the northern limit of its range (at least on 

 the Atlantic coast) in North Carolina, from which region it ranges along 

 the coastal plain and Gulf region to Texas and up the Mississippi to 

 Missouri, reaching in southern Florida its maximum of size. The 

 type of keeleri was from Florida and those of deletor from Texas, the 

 measurements of the original specimens of both species differing little, 

 being very much the same as found in the material studied in this con- 

 nection. On the other hand south Florida (Miami) specimens are 

 imiformly larger,'" an average pair measuring as follows :

 central Florida representatives.
