band on the anterior edge, the remaining portion with three lon¬ 
gitudinal parallel lines. The postscutellum is small, nearly 
triangular in form, and there lies, between the scutum and post¬ 
scutellum, a broad transverse band of dark reddish orange color. 
The meta-thorax which is the smallest of the thoracal segments, 
is wide, and closely jointed on its entire breadth with a first 
abdominal segment, so that it looks like one of the abdominal 
segments. 
The fore wings, thin, membranous and transparent, are long 
aval, narrowed at their base. They are provided with two 
nervures —subcostal and cubital. The former is longer and 
stronger, passing parallel with the costal margin, disappears 
gradually towards the external margin of the wing. The 
cubital nervure is shorter and finer than the former, arises near 
the base of the subcostal nervure, and running obliquely ter¬ 
minates about midway of the posterior margin of the wing. 
The balancer (Fig. i, f. PI. I) is composed of two parts 
nearly equal in length, of which the distal has a form of bristle 
with a free end slightly curved. 
The legs (Fig. i, e. PI. I) are all of a moderate size, and 
almost similar in length and structure. The coxal joint is oval 
and stout, the trochanter which is oblong in form, is closely 
attached to the femur, so that these two seem to form a single 
spindle-shaped segment. The tibia which is somewhat more 
slender than the femur, is beset with a few short hairs. The 
tarsus is formed of only a single long piece pointed at the free 
end, which bears a pointed claw. The tarsus is also provided 
with short hairs as on the tibia. At the insertion of the claw on 
the tarsus, are three long club-shaped hairs. 
The abdomen is nearly equal in length to the thorax, but 
is gradually narrowed towards its free end. It is jointed with 
the thorax by its entire breadth, and is composed of nine seg¬ 
ments. The terminal segment, is provided with two long bristle¬ 
like appendages lying close side by side, so as to form a single 
long filament measuring 0,25 mm. in length. 
The length and breadth of the body are on an average 0,80 
mm. and 0,25 mm. respectively. The expansion of wings is 
2,0 mm. and the caudal filament is 0,25 mm. in length (Fig. 1 ; 
1, a. PI. I).
