toward posterior margin of each segment. Genitalia extruded but indis- 
tinct, tawny and bristly. 
9. Eyes dichoptic, front perpendicular, narrowing to antennae, black, 
orbits greyish-yellow, short owing to occiput invading crown of head so 
that ocellar triangle is on front of head (fig. 12). Face narrow, longer than 
front, protruding as in male, and clothed with dense yellow pubescence. 
Antennae inserted a little below middle line of head. Oral margin pro- 
duced backwards and bristly. Occiput more or less evenly rounded; 
in deep concavity of posterior orbits. Lower orbits truncated. 
Thorax somewhat rectangular in outline, particularly in profile (fig. 17); 
prothorax yellowish-brown, to black in some lights; dorsum 6 
greyish-yellow or brown, with velvet blackish-brown stripe on each side; 
medianally is a broad deeper-yellow stripe, bordered on each side by à 
narrow, less distinct, slate-grey one; median colour-pattern distinct only — 
anterior to transverse suture, Outside lateral blackish-brown stripes thorax 
is yellowish-grey edged with blackish-brown. Humeri, from above, trun- 
cated and yellowish-grey. Scutellum greyish-yellow, with four marginal | 
bristles at each angle in addition to apical pair. Metathorax brownish- 
yellow, but black in some lights. Pleurae silvery-grey in colour, wi 
lackish-brown areas in certain light (fig. 17). Owing to sternopleurae 
being produced posteriorly and being closely applied to hypopleurae, not 
only are pteropleurae crowded upwards between meta- and sterno-pleurae, 
but middle and posterior legs arise close together immediately posterior 
to root of wings (which are attached well back on thorax) and beneath.

base of halteres, a space equal to about length of dorsum intervening - 
between anterior and middle legs, which are attached to extreme anterior 
lower angle of thorax. Chaetotaxy conspicuous, and shown in figs. 16 and 
17; pleurae bare except for five metapleural bristle 
s. 
Legs yellow, coxae with whitish reflections ; knees, tibiae of middle and. 
posterior legs, and all tarsi somewhat darker ; anterior coxae a little longer
