FAMILY VI. ACRIDID^. THE LOCUSTS. 



the transverse ridge, thus enclosing a shallow, subquadrate basal median 

 sulcus (Fig. 133, f.) Cerci slender, two-thirds as long as supra-anal plate, 

 tapering evenly in basal half to one-fourth the basal width, the apical half 

 bent gently upward and inward, the tip slightly expanded, obliquely ex- 

 cised, with upper angle rounded, ventral one acute (Fig. 132, f.) Length

Morse's types, which I have examined, were taken at Den- 

 mark, S. Car., and DeFuniak Springs, Fla., Aug. 5 15, from 

 among shrubbery in open pine woods. The known range of the 

 species extends from Fayetteville, N. Car., to Lookout Mountain, 

 Alabama, E. & H. (191G, 228) record it from a number of locali- 

 ties in the Carolinas and Georgia, it having been found by them 

 mainly among oak sprouts in pine woods and on mountain slopes. 

 In the majority of their specimens the fuscous bars of hind femora 

 were very faint or lacking, though in a few they were heavy and 



very pronounced. 



Series V. THE MANCTJS GROUP. 



This group consists of short, rather small robust species of a 

 dull brown and clay-yellow hue, having the antennae shorter than 

 hind femora; pronotum rather short, feebly widening behind, 

 more distinctly so in female, its disk obviously tectiform; pro- 

 zona not over one-third longer than metazona, the latter with 

 hind margin broadly rounded or very obtuse-angulate, median 

 carina distinct only on metazona ; tegmina oval, shorter than pro-

notum, their dorsal margins well separated, sometimes sub- 

 attiugent in male; prosternal spine short, blunt, conical or pyra- 

 midal ; hind tibiae red with black spines ; abdomen compressed, 

 carinate above, its extremity in male but little enlarged, feebly 

 upcurved; supra-anal plate triangular, the usual median groove 

 narrow ; furcula small, triangular or subcylindrical projections 

 lying on the bases of the median ridges; cerci usually short, near- 

 ly straight, substyliform or laminate; subgenital plate small, con-
