seen from all of Georgia (Austell south to Thomasville) and from 

 the Carolinas is clearly with Middle States and New England s. 

 scudderi, although showing a parallelism to one of the feature's of 

 s. texensis, but representative of the typical form in all the other 

 characters. 



Individual size variation in this species is considerable, but there 

 is also an average southward increase in the general bulk. 



The earliest date we are acquainted with on which adults have 

 been taken in the southeastern States is August 24 (Chattanooga, 

 Tenn.; Morse), while we have secured material as late as December 

 14 (Thomasville, Ga.; Hebard). 



The species was taken in sylvan surroundings, the undergrowth of 

 pine and oak woods being its favorite situation. 



The Fasciatus Group of the Genus Melanoplus. 



A tentative study of the species which have been referred to this 

 division shows that a recasting of the whole aggregation is necessary, 

 but our collated information is not sufficiently extensive to say more 

 than that fasciatus, querneus, franciscanus, nigrescens and walshii 

 are certainly, and inconspicuus probably, members of this assemblage. 

 We can state definitely that attenuatus, borealis, cockerelli, obovati- 

 pennis, rotundipennis, morsei and tepidus are not to be included in 

 the same category. Of these attenuatus is a member of the Decorus 

 Group, obovatipennis, morsei and tepidus are members of the Tribulus 

 Group and rotundipennis belongs to the Puer Group, while amplectens 

 is a synonym of ivalshii and juvencus equals viridipes, a member of 

 the Gracilis Group. Scudder's saltator belongs to another category, 

 including ascensus and other species. 



The species of this group apparently form a transition to the 

 constantly long-winged forms of the genus, the relationship being 

 chiefly, however, with the short-winged forms. The sequence of 

 species known to belong to this division appears' to us to be as given 

 above.

A member of the fasciatus group and more nearly related to .1/. 

 walshii and nigrescens than to any of the other members of the genus. 

 In general structure and coloration the new species is practically 

 identical with the two older forms, but it differs from both in the 

 slightly longer tegmina in both sexes, the broader sublamellate male
