l5ody slender, nearly linear. Antennae 

 ensifonn, equal ( $ ) or one and a half times 

 K.$ \ as long as head and pronotum. Head 

 conic: its length on top about three-quarters 

 of pi(^n(»tum. Crr)\vn Iioi'izontal (?) or 

 sliglitly ascending [$)■ Vertex laminate, 

 extending in front of eyes as long (?) or 

 longer' (J') than its width; its antei'ior mar- 

 gin parabolic; a broad-based median ritige, 

 well-developed anteriorly, disappearing pos- 

 teriorly opposite front border of eyes, curv- 

 ing slightiv downward in front to lam 

 smoothly into the front margin of vertex; 

 a shallow channel on each side of this from 

 eye to front. Eyes longer than the ver- 

 tex, about equal to the infra-ocular part of 

 the cheeks at anterior border. Profile 

 strongly reclinate, nearly straight, rounded 

 above. Frontal costa slightiv narrowed at 

 union with vertex, shallovvly sulcate, sides 

 nearly parallel, slightly divergent below. 

 Pronotum tricarinate; dorsum slightly tecti- 

 forni, truncate before and behind, sides 

 parallel; metazona two-thirds as long as 

 pro/.ona. Lateral IoIdcs transverse, front 

 nnirgin nearlv straiglit. retreating; lower 



margin sinuate; hind margin concave below, 

 the posterior angle about square. Proster- 

 num bearing an obtuse tubercle. Metasternal 

 lobes subcontiguous, $, not distant, $. 

 Hind femora slender; of (J bearing a long 

 stridulating rasp of fine teeth on the distal 

 three-fourths of the basal half. Hind tibiae 

 with 12 to 19 spines on exterior margin, 

 apical spine not present. Tegmina usually 

 abbreviated ; of $ two-thirds or three-fourths 

 as long as hind femora, rounded at apex, 

 pellucid on distal two-thirds, the scapular 

 area dilated, regularly reticulated with 

 oblique veinlets. Tegmina of $ acuminate, 

 opaque, scarcely reticulate, about as long as 

 head and pronotum. Wings abortive, half 

 as long as tegmina. Individuals occur with 

 fully developed wings and tegmina nearlv or 

 quite reaching apex of hind femora; in these 

 the apex of the tegmina is rounded. For 

 this form the name reversa is here pro- 

 posed. GeTiital segment of ^ twice as long 

 as wide; extending twice the length of the 

 anal plate horizontally backward, lower mar- 

 gin slightly ascending, sides straight, extreme 

 tip a little rounded, reaching or slightly 

 passing the apex of hind femora. Ovijiosi- 

 tor of 9 short, scarcely exserted, external 

 margins with a stout tooth, upper valves 

 denticulate at base. The end of abdomen 

 equals or (usually) passes the lip of hind 

 femora a little, sometimes several mm.
