the combined lengths of the distal three joints, about one and three quarters 

 times the lengths of the second joints, that of the cephalic tarsus somewhat 

 longer, bent at its proximal third, the hairs on its ventral surface forming a 

 strigil with the ctirved, forked tibial spur of the cephalic tibia ; the tines of 

 the fork of the latter are unequal. Cephalic tibijE and femora subequal in 

 length, the tibia of the other legs longer than the femora. Caudal coxae more 

 elongate-conical than those of the other legs, which are somewhat globular. 

 Tibial spurs single. 



Lateral ocelli somewhat their own width from the respective eye margins, 

 farther apart from each other than each is from the cephalic ocellus. 



Sculpture of the body not conspicuous, apparently absent, the abdomen 

 smooth, the scutellum with the usual transverse line of minute foveas near its 

 tip, curving with the margin at that point, the metanotum comparatively simple, 

 apparently without carinse ; parapsidal furrows distinct, complete ; along the 

 median line the scutellum and mesoscutum are subequal, the posterior margin 

 of the latter nearly straight, slightly convexed. Metathoracic spiracle minute, 

 like a point, round. Vertexal carina present, complete. Abdomen conic-ovate, 

 the ovipositor slightly exserted, or rather its valves. 



Antennae widely separated, inserted near the margins of the eyes, g-jointed, 

 the funicle nearly filiform, ending in a very large, solid, ovate club joint; 

 pubescence not conspicuous. Scape dilated ventrad, longer than the pedicel 

 and wider, subequal in length to the second funicle joint. Pedicel obconic, 

 subequal in length to the proximal funicle joint but much wider and slightly 

 longer. First three funicle joints equal in width, slender, cylindrical, the first 

 and second long or moderately long, the third short ; first funicle joint twice 

 the length of the fourth, which is the shortest funicle joint, but only two thirds 

 the length of the second joint which is the longest funicle joint, slightly curved, 

 over twice the length of the short third joint of the funicle and about thrice 

 the length of the fourth ; third joint longer than wide but abruptly shorter, 

 about a fourth longer than the fourth joint ; the latter shortest yet longer than 

 wide, slightly wider, ovate-quadrate ; fifth and sixth joints cylindrical oval, 

 each lengthening slightly, the third joint intermediate in length between them. 

 Club abruptly very large, as long as the combined lengths of the first two 

 funicle joints. The club with several conspicuous, short, longitudinal grooves 

 along the side of one aspect and also leading from the apex. In immounted 

 specimens the antennae nearly hispid, with short, whitish hairs. 



(From 10 specimens, two thirds inch objective, one inch optic, Bausch 

 and Lomb.) 



Male.— The same but having the pallid yellow of the legs dusky yellow, 

 the antennae dusky black excepting the pallid yellow scape and pedicel ; and 

 moreover differing in the shorter, more rounded abdomen, the lesser number 

 of lines of discal ciliation of the fore wing (4 or 5 lines)* and in the longer, 

 filiform, slender antennae. 



Antenn.'c 13-jointed, normal, the pubescence moderately sparse, the longitu- 

 dinal strire of the fvmicle joints (2-10) visible but not conspicuous, the distal
