exterior surface of the membrane is closely studded with minute triangular 
denticles, except towards the base and on the narrowed distal portion. The 
margins for the most part are fringed with short stiff setae which also occur 
on the exterior surface of the infolded portions of the membrane: these are 
essentially elongated denticles. 
Distal dorsal bristle of the upper jaw with only a trace of short fine lateral 
setose prickles in its distal part. It is precisely similar to the other bristles 
which occur on the outer and upper surfaces of the upper jaw: the bristle 
figured in text fig. 2 b along with the dorsal bristle is more distinctly setose 
along its length than the dorsal bristle. Near their apices these bristles are 
all quite smooth.

Tergites. On the first abdominal tergite, and to a less extent on the second 
and third, there are some short stout scattered spines : on the posterior tergites 
such spines do not occur, nor are the numerous short cylindrical bristles so long 
as the above mentioned spines. 
Sternites. On the second sternite there is a pair of long curved fleshy hairs 
on each side. The hairs of each pair are closely approximated along their 
whole length. The pairs arise from adjacent points, near to the midline, and 
cross each other at their apices.
