11. & H. (1910, 206) give records of its distribution extending from 

 Fayetteville, N. Car., south and west through southern Georgia 

 and throughout Florida. They state that intergrading forms be- 

 tween it and damnified occur about Florence, S. Car., and Wil- 

 mington and Fayetteville, N. Car. The longer tegmina and more 

 slender form easily distinguish the Florida specimens from those 

 of typical damnified at hand from Indiana and Arkansas, and 

 while the two forms are very closely related, eaJidior is probably 

 worthy of its racial name. 



Tribe IV. MELANOPLI. 



This tribe comprises the great majority of the true locusts or 

 Acridida? of the Eastern United States and Canada. They are 

 for the most part of small or medium size, and all agree in having 

 the fastigium of vertex more or less decliveut and gradually 

 merging into the frontal costa ; foveolre wanting or very minute; 

 face moderately oblique or subvertical ; antennae filiform, longer 

 than the fore femora; eyes of moderate size, usually not very 

 prominent, the interocular space generally narrow; frontal costa 

 not prominent, generally silicate below the ocellus; disk of pro- 

 notiim nearly flat, never crested, prozona generally longer than 

 nietazona, smooth or feebly punctate; metazoua usually densely 

 punctate; lateral carime usually indistinct or wholly wanting; 

 lateral lobes with hind margin straight or nearly so, their pos- 

 terior lower angle obtuse; tegmina often very short, rarely wholly 

 wanting, usually fully developed and tapering gradually through- 

 out their length; wings transparent; prosternal spine rather 

 prominent and conical, rarely truncate; hind femora generally 

 surpassing the abdomen ; hind tibia 1 with nine to 14 spines on 

 outer margin, the apical one lacking; second hind tarsal joint 

 only half as long as the first; apex of male abdomen more or less 

 enlarged and upcurved, the cerci and subgenital plate variable in 

 the different genera.
