brown; marginal band faint and interrupted in the middle. Posterior margin 
very slightly convex, becoming deeply curved towards the lateral margins, 
which are slightly rounded. 
Metathorax. Slightly wider, and longer than the prothorax, the lateral 
margins curved and bordered with a narrow dark band, the posterior margin 
slightly convex. 
Abdomen. Oval in shape, broadest at third segment, whitish in colour, 
with a small brown transverse band on the dorsal surface of segments 1-6; 
seventh segment with the transverse band involving the whole of the segment. 
On the dorsal surface, first segment bare, with a deep marginal band of dark 
brown; second segment with a median group of four hairs widely spaced, and 
one pair at each lateral margin; third segment with twenty pustulated hairs; 
fourth segment with a row of sixteen pustulated hairs; fifth segment with a 
row of fourteen pustulated hairs; sixth segment with a row of fourteen hairs 
and two short hairs at the angle of the postero-lateral margin; seventh 
segment with a semicircular row of twelve pustulated hairs; last segment 
bilobed at the apex, with a row of eight pustulated hairs, and two short hairs 
on each lobe. 
Male. Total length T16 mm., length of head 0*30 mm., length of prothorax 
0*11 mm., length of metathorax 0-12 mm., length of abdomen 0-63 mm. Width 
of head 0-30 mm., width of prothorax 0-21 mm., width of metathorax 0-22 mm., 
width of abdomen 0*40 mm. 
Head. The head generally resembles the female in outline, except that 
the antennal sinuses are much wider. Ocular projections extremely small. 
Antennae large and backward pointing, extending well beyond the occipital 
margin of the head, the first segment large and broad; second segment 
practically the same length as the first; the third segment the longest. On the 
dorsal surface of the head, a row of six small pustulated hairs close to the 
anterior margin, two small hairs situated in the centre of the head, mid-way 
between the bases of the antennae and the ocular projections, and a group 
of three to four hairs on the temples. 
Prothorax. Produced sharply posteriorly, with a deep emargination at the 
posterior margin; lateral margins slightly rounded. 
Abdomen. Oval, widest across the fourth segment. First segment entirely 
lacking the deep marginal broad band of the female; a brown transverse band 
on the dorsal surface of segments one to five; segments six to eight with an 
irregularly shaped and fused transverse band; last segment oval, with five 
to six short hairs along the posterior margin; first segment with a row of eight 
hairs; second segment with a row of fourteen hairs; third segment with a * 
row of sixteen hairs; fourth segment with an unevenly spaced row of fourteen 
hairs; fifth and sixth segments with a row of fifteen to seventeen hairs; last 
segment with a closely set row of ten hairs. 
Genitalia. Conspicuous, as shown in Plate II, fig. 9.
