oped apical tubercle, and by the very strongly protuberant vertex 

 in both sexes. 



Adults of the insect were found scarce in the undergrowth of a 

 heavy chesnut forest on Southwest Mountain (a hill near Orange), 

 and among oak sprouts in a tangle of other plants and vines in pine 

 woods (Macon). The above records extend the known range of the 

 species both northward and southward. 



The Puer Group of the Genus Melanoplus. 



The following species belong to the present group, M. puer, rotundi- 

 pennis, stegocercus, mirus, scapularis and strumosus. In all of these 

 species both sexes have the prosternal spine prominent and very 

 broad, flattened cylindric with apex transversely excised, the sides 

 rounded; the caudal tibiae are glaucous, often more or less flavescent 

 at base and tip, with spines black or black-tipped. The species 

 are property associated as listed above, no one of them shows very 

 close affinity to any of the others, however, as each has one or several 

 decided and unusual characters peculiar to itself. 



Scudder's association of the then known species, puer and rotundi- 

 pennis, is of no value, the situation in regard to the latter is discussed 

 below. Morse, at the time he described strumosus, did not discuss 

 its relationship.

Examination of the types of M. rotundipennis and M . inops shows 

 that the two are absolutely synonymous. The figures of the type 

 of inops in Scudder's Revision are very poor, the furcula indeed 

 being wholly overlooked; the figure of rotundipennis is, however, 

 quite satisfactory, though the base of the cercus in lateral aspect is 

 drawn much too wide. 



Females of this species constitute the basis for Scudder's record
