 Fig. 6. site the insertion of the antennae ; ocelli large and 



prominent, placed in a triangle on the vertex. Antennse 

 inserted on the middle of the face, nearly as long as 

 the body, gradually slenderer towards the tip, 12- 

 jointed in $ , 13 in % , first joint moderate, stout, second 

 very short, third a little longer than first and second 

 together, fourth and five following joints subequal, each 

 longer than the third, remaining joints shorter, sub- 

 equal. Thorax short, rather gibbous, smooth; meso- 

 thorax convex ; pleura with a deep fovea in each side ; 

 scutellum moderate, rather prominent ; metathorax moderate, convex, 

 smooth, gradually smaller towards the insertion of the abdomen, around 

 which the margin is prominent and somewhat reflexed. Wings rather 

 long, narrow ; costal uervure slender ; stigma short, very narrow, linear ; 

 marginal cell long, narrow, extending to the tip of the wing, sublan- 

 ceolate ; two rather large, subequal. elongate submarginal cells, the 

 second receiving the long, stout and very oblique first recurrent nervure 

 about the middle, and receiving at its tip a very faintly defined, second 

 recurrent nervure ; posterior wings with a few irregular nervures. Legs 

 simple, long and slender; coxae robust; posterior trochanters short, 2- 

 jointed; femora slightly thickened in 9, the anterior pair somewhat 

 curved ; tibiae slender, about as long as the femora, the spurs very long, 

 slender and acute, the two anterior tibiae apparently with only one spur 

 at tip, the four posterior tibiae, each with two spurs at tip, the outer 

 one the shortest ; tarsi 5-jointed, nearly as long as the femora and tibiae 

 together, very slender in the % , flattened and dilated beyond the first 

 joint in the 9 • pubescent, with a long lobe on each side at tip, and 

 from each lobe proceeds one or two long setae ; tarsal claws, stout and 

 bifid. Abdomen elongate, petiolated, smooth, inserted just above the 

 base of the posterior coxre ; first segment nearly as long as the remain- 

 ing segments together in the 9 , shorter in the % , slender at base and 

 gradually swollen beyond the middle, much more strongly so in the % ; 

 remaining segments together broadly fusiform, slightly incurved at tip 

 in the 9 .
