clypeus to the eye forming a very acute angle, concave, sinuous towards 

 the clypeus then emarginate, concave near the eye. The prothorax a 

 little more than twice broader than long, finely striated transversely in 

 the posterior half and with several less marked impressions anteriorly. 

 Tegmina opaque with four discoidal areas of which two are anteapical, 

 five apical areas and three in the marginal space ; a black dot occurs at 

 the tip of the claval angle. Wings hyaline with the third sector re- 

 united at the internal branch of the bifurcation of the second sector, 

 then bifurcate and forming a long angular cell. Pectus and abdomen 

 yellow : the latter a little deeper towards the base of the dorsal segments. 

 $ has last segment of the abdomen hardly longer than the preceding, 

 apical margin straight ; a very small genital appendage ; genital plates 

 very narrow at the tip almost as long as the hypopygium and pubescent 

 on the sides ; the hypopygium a little broader and pubescent, the anal 

 tube is surrounded by it and extends beyond it by very little. The 2 

 has the last segment twice as long as the preceding, convex at the supe- 

 rior margin, angular in the middle and weakly sinuated on each side ; 

 the genital appendages or valvules are more than twice as long as the 

 preceding and the oviduct extends beyond them by about one-third 

 (Signoret). Stal writes : — Shining, sordid whitish-yellow ; head (eyes 

 excepted) almost equally long and broad, longer by half than the thorax, 

 anteriorly slightly narrowed, smoothish : tegmina opaque ; eyes fuscous. 

 ^ Body long 5 ; broad, hardly 2 millims : 2 , body long 6 ; broad, 2 

 millims : Stal gives ? long 8J ; breadth thorax 2 millims.

Separated from Hecahis, Stal, by the presence of six discoidal areo- 

 las. Body depressed : head prolonged in front, foliaceous on the ante- 

 rior margin of the vertex, with a groove throughout its entire length, 

 vertex depressed, also the frous, the latter with the grooves and lateral 

 sutures extending to the anterior border of the head : gense sinuated, 

 rounded in the middle : the lores occupying the entire space between the 

 margin of the gena3 and the frontal suture : sides of clypeus almost 

 parallel, rounded at the tip, one and half times longer than broad : pro- 

 thorax transverse, almost broader than the head with the eyes : tegmina 

 transparent hyaline with a narrow marginal limbus : rest as in Hecalus 

 (^Signoret) .
