small one near its base ; the lower branch has an apical spot and 
a larger one near its base. The third long vein has a black apical 
spot and a dark patch on each side of the cross-veins ; the fourth 
is mainly dark on each side of the cross-veins, and has two dark 
spots on the upper branch, one near the base and two on the 
lower branch ; the fifth has a black spot at its root, three on the 
upper branch and one at the apex of the lower branch ; the sixth 
has two dark spots. The first sub-marginal cell is a little longer 
and decidedly narrower than the second posterior cell, its base 
slightly nearer the apex of the wing than that of the second 
posterior cell, its stem as long as the cell; stem of the second 
posterior considerably longer than the cell ; supernumerary and 
mid cross-veins in one line, the posterior rather more than twice

its length distant from the mid, but very variable, sometimes 
step-like ; fringe with pale spots. 
Length.—A4 to 4°8 mm. 
Halitat.—Luzon, Philippine Islands (Miss Ludlow). 
Time of capture.—April. 
Observations.—Described from a number of specimens. A 
very variable species, somewhat like Rossii at first sight, but 
easily told by the spotted legs and much shorter fork-cells. The 
base of the first sub-marginal is always slightly nearer the apex 
of the wing, and the costal spots differ slightly, but are to some 
extent variable. The cross-veins are most unstaple. The palpi 
are very similar, but the apical band in Rossii is rather longer. 
The chief difference is that in Rossii the second white band is a 
third of the way down the palpi; in this species it is less, and the 
black intervening area is much smaller (vide Fig. 19).
