SYSTEMMATIC. 



The following classification is based upon Kieffer's Mono- 

 graph of the Bethylidae (1914).

Female: Body sometimes lengthened or very elongate, sometimes 

 somewhat compact. The length varies between 1.5-10 mm. Head 

 viewed dorsally transverse, almost square or rounded. Mouth on the 

 anterior end of the head. Mandible three or four-dentate, in one 

 species stated to be two-dentate. Antennae ten- jointed originating close 

 behind the clypcus, slender, filiform, or distally slightly and clavate. 

 Eyes very large and prominent (Lestodryinini and Gonatopodini) or 

 moderately large in the others. Ocelli three, mostly forming a triangle, 

 in apterous forms often lacking. Wings and tegulae often entirely 

 lacking, seldom reduced. Fore wings with pterostigma, two or three 

 closed basal cells (subcostal, median, and submedian), one distal and 

 generally anteriorly open radial cell. Anal vein often distinct. Traces 

 of a cubital as well as two discoidal cells, namely, one distal median 

 cell and one distal submedian cell; in the AphcJopini and in two other 

 species only costa and radius are developed. Hind wings lobed. Legs 

 slender, femur in form of a reversed club, tibia only slightly thickened, 

 spur of fore tibia with a transparent lamella, extending for its length, 

 abruptly ending before the tip, the spur thus appearing bi-lobed, claws 

 of the four hind legs and in the male in the fore legs generally with one 

 broad proximal or divided tooth. 



In all females, except in the tribe Aphelopini the fore legs are mod- 

 ified. The coxa is excessively elongated, often more than half as long as 

 the femur, the trochanter is a long, often stalked proximally and some- 

 what curved joint, which is often five times as long as the corresponding 

 joint on the other legs, femur proximally strongly club-shaped, tibia 

 thicker and shorter than the others, the tarsus ending in an almost 

 bare chela, which is generally thrown backward, hdng close to the 

 tarsus, ventrally or dorsally, and generally reaching to the proximal end 

 of the third, seldom the fifth, the fourth or the second joints; the fore 

 legs are therefore called "Raubfusze," "Pedes raptorii," the third tarsal 

 joint, often also the second, present a proximally, oblique or perpen- 

 dicular ]3rojccting process, from which long, stout, bristles project, and 

 lie against the distal end of the chela, while the fourth joint, for the 

 same purpose, on the whole ventral side appears more or less convex 

 or flattened; also the third and fourth joints on both sides bear single, 

 very long, stout bristles, which geiierally provide the chela with a 

 support. The medial chela arm, which generally lies against the under-
