SAROTA. 435 
suggested these alliances, but on further dissection the separation of Sarota into a 
distinct genus seems unavoidable. Not only do the wings differ in neuration, but the 
spiny tarsus, in addition to its hairiness, as well as the difference in the sexual 
characters of the male, all indicate generic distinction. The subcostal nervure of the 
primaries emits two branches before the end of the cell and one after it; the lower and 
middle discocellulars are almost if not quite atrophied; there is a short upper disco- 
cellular directed outwards. The secondaries have a basal nervure, the discocellulars 
are completely atrophied, a small spur beyond the first branch of the subcostal marks 
the position of the upper discocellular ; a similar spur on the median beyond the second 
branch marks the position of the lower discocellular ; the first median branch and the 
median itself are both elongated and carry lobes beyond the general contour of the 
outer margin; the anal angle is produced and carries a long fringe. 
The front legs of the male have the trochanter inserted a little beyond the middle of 
a short slender coxa, femur =? coxa and is slightly dilated towards its distal end, tibia 
=coxa dilated in the middle, tarsus <tibia densely spined beneath, and with two con- 
strictions, the remains of former joints. Palpi have a slender terminal joint =4 middle 
joint. Antenne have thirty-six joints, whereof the terminal fourteen form a moderate 
club. The eyes are smooth. 
The harpagones have two lobes, the lower one short and pointed, the upper one 
elongated and blunt, both densely setose. There is a short slightly depressed hook 
between the lobes of the tegumen; the penis is exceedingly long, reaching backwards 
to the third segment of the body, where it passes the sixth segment there is a short 
patch of dentate papille, it bends downwards towards its extremity, and there is the 
usual strap connecting it with the harpagones. 
In S. gyas the neuration of the primaries is very similar to that of S. chrysus; it also 
has a short upper discocellular ; the secondaries are without the prolongation of the 
median nervure and its first branch. The tarsus of the front legs of the male has a 
few spines beneath, which appear to be arranged in pairs, indicating the position of 
former joints. 
The secondary male organs are very similar in both species, the penis being shorter 
in A. gyas. The female of this latter species has two well-defined flattened chitinous 
spines in the bursa copulatrix.
