similarly spatulate, are definitely shorter and broader. The penis 

 is, however, not only differently developed than in any other 

 species but shows decidedly the highest specialization. 



Type. — 8 ; Nantahala Mountains, extreme western North 

 Carolina. Elevation 2500 feet. October 5, 1933. (C. F. Wal- 

 ker). [Hebard Collection, Type no. 1319]. 



Size medium small, form compact and fairly robust for the brachypterous 

 Melanopli. A weak longitudinal concavity present between the eyes and 

 frontal costa weakly concave below the median ocellus, above that point 

 broader and deplanate, rounded into the deplanate fastigium of the vertex. 

 Antennae medium, decidedly shorter than caudal femur. Eye prominent, 

 vertical length intermediate between that of sub-ocular sulcus and that of 

 cheek. Pronotum with medio-longitudinal carina present only in meta- 

 zona, three transverse sulci well denned (complete in type, with first or 

 first and second briefly obsolete mesad in paratypes) ; caudal margin 

 broadly convex, its lateral portions nearly straight. Tegmina represented 

 by small rounded moderately separated pads, their apices showing a trace 

 of angulation, their surface evenly weakly convex and covered by a rather 

 regular network of decided veinlets. Prosternal spine short, stout, taper- 

 ing abruptly to the sharply rounded apex, approximately as long as basal 

 width. Furcula represented by a pair of short stout parallel fingers, their 

 swollen bases attingent. Supra-anal plate rather small and narrow tri- 

 angularly shield-shaped, approximately one-third longer than broad ; median 

 sulcus very deep in proximal two-thirds, lateral portions deeply concave. 

 Cerci short and stout, tapering moderately in proximal half, then expand- 

 ing into the moderately spatulate apical portion, there with outer surface 

 convex but dimpled at the distal margin. Subgenital plate small, blunt 

 conical, at the transverse rounded apex very slightly produced (with sur- 

 face there sometimes dimpled). Penis with base very large, its shaft short 

 and thick, the margins flaring in cephalic meso-internal portion into bilobed 

 projections which have their margins microscopically serrulate; from within 

 these project a pair of small vertical transverse and before them a pair 

 of small vertical longitudinal lamellae, just caudad of which the simple 

 aciculate apices of the ectoparameres project not as far. 



Allotype. — 9- ; same data as type. [Hebard Collection]. 



Larger and more robust than male. Concavity of interocular area and 

 frontal costa even weaker and the former more limited in extent. Teg- 

 mina faintly more separated (in allotype, but attingent in paratype). Pro- 

 sternal spine similar to that of male. Ovipositor valves moderately elongate, 

 curvature at apices extensive, not strong. 



Coloration. — The small series before me is dark brown with caudal 

 femora showing externally the usual (in the group) three paler areas ex-
