thorax rugoso-reticulate, brownish black; antennae entirely, all legs 

 including their coxae and the abdominal petiole pale yellow ; all coxae 

 and petiole of abdomen smooth; abdomen, except petiole, polished, 

 black; mouth parts pale yellowish, mandibles blackish at apex; wings 

 hyaline. Antenna 11-jointed; scape subcylindrical, five or six times 

 as long as broad, about equal in length to five following joints com- 

 bined; pedicel about twice as long as broad; ring joint subquadrate; 

 seven joints of funicle subequal and subquadrate or very slightly longer 

 than broad; club not thicker than funicle, very slightly longer than 

 two preceding funicle joints together, practically solid but with dis- 

 tinct traces of two transverse furrows. Head transverse, much wider 

 than thorax, perfectly smooth except for a few very weak and irregu- 

 larly transverse lines on the occiput; occiput very slightly concave; 

 ocelli in a nearly right-angled triangle, postocellar line distinctly 

 shorter than ocellocular line; frons practically without scrobes; 

 clypeus polished, nearly twice as wide as long, its anterior mar- 

 gin broadly rounded; clypeal foveae and groove distinct but 

 very shallow; supraclypeal area not defined, i. e., not limited 

 laterally by grooves; malar space a little shorter than length 

 of eye; mandibles long and curved, the right with three teeth, 

 the left with two. Thorax short, moderately convex, with 

 nearly uniform coarse reticulation; pronotum concealed from above; 

 parapsidal grooves complete and distinct; scutellum nearly round, 

 not especially convex and withotit a transverse furrow but with an 

 irregular transverse carina in the normal place for the furrow; pro- 

 podeum about as long as scutellum and with similar coarse reticulate 

 sculpture, without definite median carina and without lateral folds, 

 spiracular sulci present but obscured by the rough sculpture; legs 

 rather slender, their coxae and femora smooth; forewing normal m 

 size, bare from base to a little beyond apex of submarginal vein, mod- 

 erately ciliated beyond that point and with a few hairs in the costal 

 cell; marginal fringe rather short; veins very slender, the marginal 

 vein about half as long as submarginal; stigmal vein very short, post- 

 marginal two or three times as long as stigmal. Abdomen including 

 the petiole about twice as long as thorax; petiole as long as gaster, very 

 slender, and slightly bowed from end to end; gaster triangular m 

 lateral profile, perfectly smooth and shining; ovipositor slender, ap- 

 parently straight, and without distinct teeth, normally concealed. 



Male.— Length. 1.9 mm. Almost indistinguishable from the female 

 except by the genitalia. The antennae are very slightly more slender 

 with the hairs a little longer. The abdominal petiole is practically 

 the same as in the female and the gaster is a very little smaller. 



Type locality.— KurIsl Lumpur, Federal Malay States.
