margin of the head, the basal joint of the flagellum longer than 

 the 2nd, the apical four joints longest of all ; head posteriorly 

 attenuated into a cylindrical neck, the posterior border of which 

 is strongly margined. Thorax elongate, narrow, anteriorly at- 

 tenuated as the head is posteriorly, but not so long nor margined, 

 above convex ; pro-mesonotal suture indicated but not distinct ; 

 mesonotum oblique, convex above, roundly raised a little pos- 

 teriorly ; meso-metanotal suture deeply impressed ; the basal 

 portion of the metanotum elongate, rounded, above the apex 

 divided into two acute dentate angles, the emargination between 

 them being smooth and polished ; legs very long and slender. 

 Pedicel : the 1st node conical, rounded above, with an elongate 

 petiole in front and a shorter one posteriorly ; 2nd node from 

 above suboval, rounded above ; abdomen short, broadly oval. 



$ . Closely resembles the , but the sculpture of the head is 

 more marked and the transverse rugosity on the mesonotum and 

 metanotum is coarser. The antennae and legs are lighter in colour ; 

 the scutellurn gibbous. The wings as in the <$ , but the nervures 

 darker. 



" c? . Black ; the mandibles, the flagellum of the antennae, the 

 articulations of the legs and the genitalia testaceous ; the apical 5 

 joints of the flagellum subequal and longest ; legs slender. The 

 fore wing lightly infuscate, the costa pale ; the transverse nervure 

 joins the external branch of the cubital nervure. The form of the 

 thorax is shown in the figure." (Emery.}

$ . Head, thorax, legs and pedicel yellowish or reddish brown, 

 abdomen dark brown, some specimens are entirely dark brown ; 

 smooth, highly polished and shining, very slender, the metanotum 

 only very minutely and closely punctured, iu certain lights sub- 

 opaque. Pilosity pale yellow, long and most plentiful on the 

 scapes of the antennae and tibia? of the legs. Head with the man- 

 dibles elongate and oval, produced posteriorly into a long con- 

 stricted neck with the margin recurved ; mandibles finely longitu- 

 dinally striate ; clypeus slightly convex in the middle, its anterior 

 margin arched ; frontal area sunk and depressed; antennal hollows 

 deep and large, a few striae between them and the eyes ; antennae 

 very slender and filiform, the scape extending beyond the posterior 

 margin of the head by about one-third of its length ; flagellum 

 without any distinct club, but the apical 4 joints much elongated ; 

 eyes lateral, proportionately somewhat large, prominent, and much 

 closer to the anterior than to the posterior margin of the head. 

 Thorax narrow, elongate, the pronotum convex, produced anteriorly
