SCALY WINGED COPEOGNATHA. 89 
pubescence rather long and moderately compact. Clypeus moder- 
ately convex with fine silver gray hairs. Labrum smooth shining 
dark brown. Maxillary palp brownish yellow, apical third of the 
end joint dark brown. 
Thorax brown, mesonotum covered with‘ silver white scales. 
Legs brown, the following parts pale brownish yellow :—Trochanters, 
usually also the base of the femora, apex of the femora and of the 
tibie. Scales of the femora, especially above at the apex, silver 
white. The length of the anterior tibia is 0-4 mm., of the middle 
tibia 0°54 mm., of the hind tibia 1 mm. The lengths of the 
tarsal joints in the fore foot, 0:16, 0:05, 0°06 mm. ; in the middle 
foot, 0°25, 0°05, 0°06 mm.; in the hind foot 0°4, 0:06, 0-07. 
The ratio of the hind tarsal joints is therefore as 52: £: 1. First 
hind tarsal joint with about 16 ctenidiobothria. Claws (fig. 75) 
long and slender, with acute tooth rather far before the apex and a 
feeble tooth rudiment in the middle between this and the setiform 
empodial appendix. 
Wing membrane hyaline. Pterostigma (fig. 14) broad and large. 
The pattern of the fore wing produced by the scaling is shining 
silvery gray-white with brown to gray-brown markings. The 
markings are distributed as follows :—On all the ends of the veins 
occurs a spot, those of the posterior margin larger ; through the 
middle of the axillary cell a narrow band passes obliquely outwards 
from the posterior margin to the anterior margin without however 
quite reaching the latter ; with this band the marginal spots at the 
ends of an and cu, are connected ; the marginal spot at the end of 
cu, communicates with a larger irregular spot in the wing centre, 
which encloses a small round silver white spot ; the marginal spots 
of the wing apex also partly anastomose among themselves. In the 
middle of the wing base a brown spot. Marginal hair relatively 
short, yellowish white, blackish at the brown spots. Hind wing 
with narrow radial cell (R);71 near the base of cu. Veins brown. 
Marginal hair of the anterior border relatively short and brown, 
that of the posterior border long and yellowish white. Membrane 
intensely iridescent in all colours. . 
Ground scales (fig. 50 gs) longish ovate, almost imperceptibly 
acuminate at the apex ; cover scales (ds) similar, though slenderer 
in the basal portion. Macrochete (fig. 50) finely pubescent in the 
distal half. 
Length of fore wing 2°3 mm.; wing expanse 5} mm.

February, 1905, two; March, 1905, two; collected by Mr. E. E.
