SCALY WINGED COPEOGNATHA. 93 
thick, yellow sete. Tarsi without scales. First hind tarsal joint 
with close-set and short sete, with 20 ctenidiobothria, which how- 
ever are composed of very delicate pale yellow hairs and so do not 
strike the eyes of the observer. Second hind tarsal joint without 
perceptible ctenidiobothria ; the hairs may be so fine and short 
that they do not stand out from the fine pubescence of this joint. 
Third hind tarsal joint with only three long hairs at the end of the 
outer side, otherwise with extremely short, fine, and fairly compact 
pubescence. Claws long, narrow and acute, a stout tooth near the 
apex. Empodium with a seta on each side. Ratio of the hind 
tarsal joints as 5: 1: 3. 
Fore wing brown, closely beset with symmetrical scales bluntly 
acuminate in front, and amidst these long, thin, curved hairs, the 
latter occurring especially on the apical half and here particularly 
on the veins. Scales gray-brown to brown, intermingled with 
silvery scales ; a streak in the costal cell, a marginal spot in each 
of cells Ri, Ra+ 3,Cu1 and An with perfect silver lustre. Analis 
with hyaline seam. The hinder portion of the wing base is formed 
by a smooth pale brown area which carries about 27 hair cupules 
but is without hairs. The area between costa and subcosta pale 
brown, strongly thickened and chitinised, scaleless, with only 
individual long erect sete ; most of the sete are relatively short 
and recumbent. Only the margin of the outer wing half with very 
long close-set and delicate hairs; the hairs inserted upon long 
stalked cupules arranged in cross rows. The rest of the anterior 
margin only shortly pubescent, still the single hairs are faintly 
expanded, scale like. The radial branch (r,) of the pterostigma 
unites for a short distance with the peduncle of the radial fork, the 
radial ramus for a fairly long distance with the media. The radial 
fork nearly 14 times the stalk length ; peduncle of the cubital fork 
3 of cu, and ft ofcu,. Stigma sac occurs as a strong tracheal expan- 
sion at the base of that portion of the subcosta which abuts upon 
the pterostigma, with many irregular, torn, and separated parts of 
the tracheal spirals. 
Hind wing brownish hyaline; veins and membrane of the apical 
half fairly closely pubescent. Wing border with exception of the 
anterior margin of the costal cell with very long and compact hair. 
The two branches of the media without stalk. The portion of r 
which bounds the extremely narrow radial cell R in front is some- 
what curved, with a little sharp trachea, expanded and represented 
by a fairly broad brown pigment seam. 
Membrane of the hind wing in certain lights intensely iridescent 
deep red, red violet to blue, partly with deep black lustre The
