Figures 3, 13, 14, 28, 31 
Body mostly black ; vertex black anteriorly, brown pos- 
teriorly; rostrum entirely brown; thorax black dorsally, 
yellowish brown laterally, meso- and meta-notnm as a 
rule with a broad brown median band ; 1st to 6th abdomi- 
nal segments of male black dorsally and ventrally, last few 
abdominal segments reddish brown, anal horn absent ; the 
hind border of third tergite slightly prolonged behind, 
and in contact with the small, sharp conical production on 
the median axis of the fourth tergite ; abdominal segments 
of female entirely black. Fore wing : length, 12.5 mm. ; 
width, 3 mm.; membrane hyaline, markings sooty brown; 
pterostigmal band complete, with a broad basal branch 
and a separated narrow apical branch ; basal band inter- 
rupted, represented by two large spots ; apical band broad, 
with a large hyaline spot posteriorly; basal spot very 
small; marginal spot large, not extending beyond the vein 
Bl; pterostigma brown, very prominent. Hind wing: 
length, 11.5 mm. ; width, 3.3 mm. ; similar to fore wings, 
except that the basal spot and the anterior part of the 
basal band are entirely lacking. <$ genitalia : genital bulb 
rounded; coxopodites long, U-shaped, furnished with a 
series of long hairs at the distal inner portions ; harpa- 
gones slender, the outer margin slightly concave at the 
middle, the inner margin with a median angle and a small 
basal concave area ; hypandrium inconspicuous ; hypoval- 
vse rather long, reaching to the base of the harpagones ; 
parameres simple and slender, each consisting of a single 
stalk, which is distinctly twisted and pointed at its apex ; 
preepiproct slender, slightly narrow towards apex, with 
a deep U-shaped distal incision; sedeagus with finger- 
shaped apical processes and slightly prolonged lateral 
processes, the distal inner margins of the former usually 
produced inwards to form a small nipple-shaped plate. 
? genitalia : subgenital plate elongated, broadened at the 
middle ; internal skeleton long, the plate narrow towards 
its base with a pair of sharp posterior arms, the axis very
