SUBFAMILY IV. COXOCEPHALINJE. 581 



Cape Sable and they b c y sweeping these grasses on the tidal flats. 

 Elsewhere in Florida it has been recorded definitely only from 

 Miami and Everglade. 



R. & H. (19151), 215) state that on the coast of New Jersey 

 spartina' is frequently to be found in great numbers on the salt 

 marshes both in Spartina patens (Ait.) and Panicularia fliiitans 

 (L.) and can there be taken with ease. At Virginia Point, Texas, 

 the series taken was chiefly macropterous and found in high and 

 heavy grasses. "It was there difficult to capture as individuals 

 were very restless and immediately sought shelter by jumping 

 down low in the bunches of grass where they were very hard to 

 follow." 



Morse, (1919) states that it is locally abundant on salt marshes 

 along the New England coast from Old Orchard, Me., to Stam- 

 ford, Conn., thus agreeing closely in extent of distribution with 

 the seaside locust, Trimerotropis inaritima (Ilarr.) 



The true status of the submaritime species, G. spartinw, stic- 

 tontcnis. aigialus and nigropleuroides, is, in my opinion, as yet 

 an unsolved problem. The first two named are very close to 

 brevipennis and the last one to both attenuatus and nigropleurus. 

 They differ mainly from these older named species in the form of 

 the male cerci, length and form of ovipositor and details of colora- 

 tion, all exceedingly plastic and variable characters. They are 

 also closely related among themselves. For example. Fox states 

 that the males of spartinw and nigropleuroides are so close "that 

 it was only after a long and arduous analysis and comparison that 

 I was enabled to determine some apparently constant structural 

 differences." Again, R. & H. (1915b, 210) state that nlgroplcxr- 

 oides, though decidedly smaller and more slender than spartinw 

 ir. New Jersey, increases southward in size and robustness so 

 that in Florida it is distinctly the larger and more robust of the 

 two. They also say : "The variation in shape of the ovipositor is 

 far greater in nigropleuroides than in any other American species 

 of the genus," ranging from rather broad and approximately 

 straight in Ne\v Jersey specimens to a distinctly though not 

 strongly upward curve in part of the series from Cedar Keys, Fla. 

 Before the descriptions of any of the four species as new forms 

 were made, R. & H., one or both of them, had recorded spartinw 

 a* X. nemorale and breripcnne; stirtomcrus as C. ensiferus ; aijiia- 

 lus as X. nigropleuruin"? and C. breripennis. and nigropleuroides 

 as X. nigropleuruin. This fact is mentioned to show which of the 

 older species each of the new forms superficially most closely 

 resembles.
