In addition to the above specimens we have before us the pre- 

 viously unique male and female, from Jacksonville, Florida, on which 

 the species was based. The Okeefenokee females are of similar 

 size to the Jacksonville one, but the single Billy's Island male is 

 somewhat smaller than the type, its measurements being: length 

 of body, 30 mm.; length of pronotum, 7.3; length of tegmen, 19.2; 

 length of caudal femur, 17.8. In coloration there is considerable 

 individual variation in the pale areas, one female having these more 

 ochraceous than the others, while one of the same sex has the same 

 areas appreciably rufous brown. The male and one of the females 

 from Billy's Island were 1 taken in coitu. The single immature 

 example from Billy's Island taken in June, and that from Honey Island 

 taken the same month, are in the same instar, while those from Billy's 

 Island taken in July and Jordan's, August 31, are in a more advanced 

 stage. The forking of the male cerci is indicated in all of the young, 

 although the difference between the two stages is in this respect 

 very appreciable. The July immature specimen is quite generally 

 blackish, but the June and August ones are oT a strongly contrasted 

 pattern with the pale areas on the dorsum of the head and pronotum 

 quite rufescent. 



Melanoplus clypeatus Scudder. 



Sandfly, Georgia, IX, 3, 1911, (R. & H.), 2cf,29. 



This rare species was found in the heaviest undergrowth in gray- 

 bark pine woods, in more or less swampy situations. Specimens 

 were very scarce, even when thorough search was made for them. 

 The males, when disturbed, jumped or flew several feet, but the 

 females were more sluggish. 



In size the series before us, three males and five females, shows 

 little individual variation, while in color we find one condition much 

 paler and more ochraceous than another. This pale condition is 

 represented by one of the original "Georgia" males, now in the 

 Hebard Collection ex Bruner, a female from Thomasville, Georgia, 

 and one of the same sex from Sandfly. The degree of paleness of the 

 anal area of the tegmina is about equal in this species and furcatus, 

 varying somewhat in each. The females of these two species are 

 rather difficult to distinguish, but the more robust and less elongate 

 caudal femora of clypeatus will serve to separate the two. 



Sandfly and Thomasville, Georgia, are the only exact localities from 

 which the species is known, it originally having been described from 

 Georgia without more exact information.
