Expan.se of wings 0'180x0 060 ... 4‘56xl'54: 
Size of body 0'140x0‘017 ... 3'55 x 0'42 
^ and 9 . — Antennae about tvv ice the length of the body ; joints 
of the scapus and first joint of the flagellum ochraceous-brown ; 
remaining flagellar joints deep brown, towards the tip of the 
flagellum apjiearing almost cinereous in a certain light. Hypo- 
stoma light reddish-brown. Front and palpi deep brown. Thorax 
ochraceous, with three fenuginous longitudinal cuneiform stripes ; 
the lateral ones appear from above to commence about half way 
1 jet ween the humeri and the origin of the wings, but they continue 
over the lateral margins down the pleurie in a broad deep brown 
band in an oblique direction to the tip of the intermediate coxae; 
the intermediate stripe l>egins at the collare ; all the stripes 
tenninate at the scutellum and do not coalesce ; two narrow lines 
of ochraceous are visible between the stripes, along which are 
single, rather sparse, rows of very short black hairs ; lateral 
margins sparingly setose ; scutellum ochraceous with scarcely any 
hail’s. Halteres yellowish on the stem, the club smoky -brown, the 
latter with a minute pubescence. Abdomen rather slender, smaller 
at the base and apex, somewhat more than twice the length of the 
the head and thorax together, ochraceous-brown, the two last 
segments (and h»a.se of the forceps) black, tinged with pale brown 
on the posterior margins ; densely clothed with long black hairs ; 
forceps rather wider than the terminal abdominal segment, 
ochraceous-brown ; lamellae of the 9 ovi[x>sitor black. Fore- and 
hind-coxae ochraceous-brown, the fir-st pair moderately setose in 
front ; femora and tibiae somewhat yellowish-brown, the fore 
femora often paler than the other two pairs ; tarsi dusky on 
account of their dense pubescence. Wings longer than the body, 
almo.st hyaline, with a greyish tint, veins umber brown; visibly 
haii-y in all the cells opening on the Ixirder of the apical portion ; 
brilliantly iridescent with roseous and smaragdine, in which the 
latter generally greatly predominates. Nearly all the veins ciliated. 
Auxiliary vein joining the costa somewhat before the base of the
