costal spots and at the base of the fork, and another near the 

 apex of the lower branch, another on the stem at the cross-veins, 

 and another at the base ; third long vein pale scaled, with three 

 black spots, one apical (the largest), the other two towards the 

 base ; a mixture of dark and light scales on the branches of the 

 second fork-cell, but the stem all dark ; three large dark patches 

 on the upper branch of the fifth, one at the apex of the lower 

 branch, and another at the base of the vein ; sixth with three 

 large black spots ; fringe with pale grey spots where the veins 

 join the costa, except at the sixth ; first sub-marginal cell much 

 longer and narrower than the second posterior cell, its base 

 nearer the base of the wing, its stem not quite half the length of 

 the cell ; stem of the second posterior as long as the cell ; super- 

 numerary cross-vein just behind the mid, curving round to join 

 it \ the posterior longer than the mid, not quite twice its own 

 length distant from it ; halteres with pale stem and fuscous 

 knob. 



Length — 5 to 6 mm. 



9 . Wing markings similar to the $ , but the fourth costal 

 spot is smaller than the second, and the basal black area is 

 represented by two small black spots ; the actual base yellow. 

 In the third vein the apical black spot is not so large as the 

 second spot. The apical half of the lower branch of the fifth is 

 dark scaled and the greater part of the apical half of the sixth,

a few pale scales, but not yellow ones, separating the long dark 

 area ; the first sub-marginal cell much longer and narrower than 

 the second posterior cell, its base nearer the base of the wing, its 

 stem not quite half the length of the cell, stem of the second 

 posterior as long as the cell ; the supernumerary cross- vein nearer 

 the base than the mid and curving round to join it, the posterior 

 about three times its own length distant from the mid nearer 

 the base.
