pubescence above antennae and extending over the face, which has a black 

 medio-longitudinal stripe and longer hairs than on the front. Mouth-parts 

 tawny, proboscis light in colour ; palpi completely tawny, the penultimate 

 joint narrow and slightly restricted along middle of sides, bearing long and 

 delicate hairs and about one and a half times the length of the ultimate 

 which is clavate, bare on proximal half but with dense stiff and short hairs 

 and numerous pits on distal half, terminating in at least 1 terminal and 1 

 subterminal stiff hair. 



Antennae dark brown, situated about the middle line and not as long as 

 width of head ; 1st joint about twice the length of 2nd, and both bristly ; 

 3rd joint with 8 segments, the first of which is the largest ; terminal segment 

 a little longer than the 1st and notched at apex, on one side of which is 

 a tuft of hairs ; the whole joint has a dense and stiff pubescence. 



Occiput depressed, shiny black with a yellowish-grey tomentum. 



Dorsum of thorax greenish-black with violet reflections and dusted with 

 a yellowish -grey tomentum ; pleurae coppery with a violet reflection, except- 

 ing the sterno-pleurae which are black ; scutellum bluish-green but narrowly 

 margined with tawny at the apex, the 4 tawny spines small or indistinct. 



Halteres pale yellow with dark-brown heads. 



Legs banded with tawny and fuscous, the latter separated by the former, 

 which lies in the middle ; posterior femora (which are enlarged) and their 

 tibiae distinctly banded, the middle femora faintly banded being mostly 

 tawny, the anterior tawny ; middle and anterior tibiae tawny but for 

 proximal fuscous bands ; posterior protarsi and epitarsi light brown, the 

 remainder dark ; middle protarsi light brown with a dark distal spot, the 

 remainder dark brown ; practically all joints of anterior tarsi dark brown. 

 In form the tarsi resemble the preceding species. 



Wings (fig. 8) clouded, axillary angle strongly curved ; costal cell widened ; 

 1st submarginal cell proximally acute, the anterior cross-vein and 3rd 

 longitudinal vein having a common origin from the 2nd vein. Third vein 

 strongly sinuated, the anterior branch arising acutely beyond the centre, 

 sinuated slightly, and nearly twice as Ions; as anterior cross-vein, which is 

 slightly anteriorly oblique. Third posterior vein reaching about half-way 

 to the posterior margin. Vein between the discal and 5th posterior cells 

 a little more than half the anterior cross-vein. Distance from the margin 

 of the confluence of the 5th and 6th veins about twice the length of the 

 anterior cross-vein. Veins brown ; submarginal cell clouded with dark 

 brown; costal cell clear; 1st submarginal cell clear except proximally and 

 along the branch of 3rd vein ; 2nd submarginal cell brown ; 1st posterior- cell 

 brown, except for a narrow elongate space near the middle ; 2nd posterior 

 cell brown except for a space toward the margin ; 3rd and 4th posterior 

 cells brown except for a large and square space on distal half into which 

 runs the 3rd posterior vein ; 5th posterior cell clear proximally the brown 

 cloud being triangular in form ; axillary lobe distinct, with a slightly clear 

 space proximally along the 6th vein ; anal cell clear but for a small cloud 

 along the 6th vein near the confluence of the 5th ; 1st and 2nd basal cells 

 clouded on proximal half and clear distally ; discal cell clouded. 



Abdomen with 7 segments, narrower than the thorax at the base but 

 becoming wider at the middle, tapering to a point and terminating in 

 the bifid tawny and styliform appendage. The whole almost blackish- 

 bronze, the 3 apical segments lighter ; 1st segment faintly tawny in the 

 middle ; 2nd almost all tawny but for sides and posterior margin ; the 

 3rd with a broad tawny spot toward the anterior margin. Ventrally the
