not attaining the tegulai. Wings present, with two or three closed 

 basal cells, and a generally distally open radial cell; pterostigma small, 

 lanceolate or linear-lanceolate; in two or three siDecies the wings are 

 rudimentary or shortened; fore legs strongly lengthened, coxa and the 

 generally stalked and curved trochanter long, femur proximally strongly 

 thickened, tibia distally thickened, first and fourth tarsal joints long, 

 second, third and fifth short, the fifth always much shorter than its 

 proximal elongation, forming with it the median chela arm, this always 

 with rows of lamellae, lateral chela arm often with rows of lamella or 

 spines. The four hind legs more slender than the fore legs, coxa and 

 trochanter much shorter, femur and tibia longer, first basally strongly 

 thickened, the last distally slightly thickened; abdomen weakly 

 depressed from above. 



Male: Head transverse, vertex convex, ocelli situated close together 

 in a triangle, seldom in an arc, eyes oblong oval, pubescent. Antennae 

 filiform, pubescent. Prothorax not visible from above, the hind angles 

 attaining the tegulag on the sides, mesonotum with or without parapsidal 

 furrows. Wings with two basal cells; radius curved or angulate, the 

 distal part generally as long or longer than the proximal, somewhat 

 shorter in Phorbas. Pterostigma linear-lanceolate or small-lanceolate.

Female: Head large, broad, vertex slightly convex, the sides con- 

 verging behind the eyes; occiput very slightly concave, eyes large, oval; 

 ocelli close together in a triangle, antennee subfiliform, slightly thickened 

 toward the tip, scape longer than first flagellas joint. Maxillary palpi 

 six-jointed, labial palpi three- jointed; mandibles three-dentate. Thorax 

 normal, pronotum large, narrower than mesothorax. The hind angles 

 attaining the tegula-, parapsidal furrows distinct, .somewhat converging, 

 propodeum distinctly truncate. Wings present or rudimentary; if 

 developed with lanceolate stigma, two basal cells, and an open marginal 

 cell, the radius long and curved. Fore legs of medium length, fourth 

 tarsal joint very long, but shorter than first; median chela ann not 

 widened and provided with lamellae but \^entrally with continuous 

 raised process; lateral arm ventrally dentate. Abdomen globose, 

 distinctly petiolate, the petiole slender, cylindrical. 



Male: Head broadly transverse, wider than thorax, vertex convex, 

 eyes oblong oval, pubescent; longer than thorax. Maxillary palpi five- 

 jointed, labial palpi three-jointed, mandibles three-dentate. Thorax 

 with sparse short white hairs; mesonotum with two distinct parapdisal 

 furrows. Wings hyaline, covered with fine white hairs and very shortly 

 ciliated. Venation pale, pterostigma lanceolate, two basal cells and an 

 open marginal cell, radial vein pale and curved, distally distinctly longer 

 than proximal]}'. Legs short. Abdomen subpetiolate, oval.
