198 NORTH AMERICAN MELANOPLI (ORTHOPTERA) 



with moderately broad bands of white or pinkish white, the former suffused 

 ventrad narrowly, the latter margined with a suffusion of blackish brown. 

 Females with these markings always absent on pronotum, often weakly 

 indicated on abdomen. Mouthparts, supra-anal plate of male (entirely or 

 medio-longitudinally only) and genicular areas of caudal femora pinkish 

 brown, genicular arches of latter blackish brown. Caudal tibiae deep 

 glaucous, caudal tarsi rich pink. 



The extremes shown by the series (all from paratypes) measure: length 

 of body S 16.2 to 18.7, 9 22.8 to 25.7; length of pronotum $ 3.5 to 4.3, 

 $ 5.2 to 5.4; caudal width of pronotal disk $ 2.7 to 2.9, $ 3.9 to 4.7, length 

 of caudal femur $ 8& to 10., $ 11.3 to 12.2 mm. 



Specimens Examined. — 58; 33 males, 22 females and 3 immature 

 individuals.

Aptenopedes aptera borealis new subspecies (PI. XIV, figs. 4 to 9.) 

 The present race has been recorded as aptera from numerous 

 localities in Georgia and northern Florida (except the narrow 

 coastal section inhabited by aptera simplex here described). It 

 inhabits the lowlands of Georgia north to Groveland, Jesup, 

 Homerville and Bainbridge; west to the latter, Woodville and 

 Carrabelle, Florida, and in peninsular Florida south to Pomona 

 (apparently, as females only were taken there), Ocala and Cedar 

 Key. A series from Kissimmee suggests discontinuous distribu- 

 tion, as the present race is not present at a number of localities 

 to the north where material has been secured. 



Type. — $ ; Bainbridge, Georgia. September 5 and 6, 1915. 

 (Rehn and Hebard). [Hebard Collection, Type No. „1293]. 



Generally similar to aptera simplex here described, differing signally in 

 having each of the dorsal lobes of the penis very strongly bilobate. Size 

 averaging larger and form very slightly more robust than in aptera simplex 

 (but marked difference in the average size is shown by different series, 

 apparently irrespective of geographic distribution. The material from 

 Jacksonville, Gainesville, Archer, Newberry and Ocala averages very large; 

 a large series from Kissimmee small, no larger than the average for aptera 

 simplex. Moreover the larger specimens appear to average slightly more
