SCALY WINGED COPEOGNATHA. 109 
tarsal joints in the middle foot are 0:19, 0:04, 0:05 mm. ; in the 
hind foot 0°29, 0°05, 0:06 mm. The ratio of the hind tarsal 
joints isas 5: %:1. First hind tarsal joints with about 14 cteni- 
diobothria. Claws (fig. 80) with stout tooth before the apex and 
setiform empodial appendix. 
Wings strongly acuminate. Membrane hyaline. Pterostigma 
(fig. 105) moderately broad. Peduncle of the radial fork somewhat 
shorter than the fork; m, ends below the wing apex. Scaling 
yellowish gray-brown with strong silken yellowish lustre. Mar- 
ginal hair long and compact, of same colour. 
Hind wing pale, with very long hair on the hinder margin ; veins 
pale brown ; membrane iridescent red to violet. 
Scales (fig. 107) elongate, asymmetrical, knife-shaped, the end 
strongly acuminate ; some narrow symmetrical. Macrochete (fig. 
104) almost in their entire length fairly closely beset with fine tooth 
like sete. 
Length of fore wing 2 mm. ; wing expanse 44 mm. 
Ceylon. Peradeniya. Under loose bark on trunk of Artocarpus 
integrifolia ; March, 1905, two specimens, collected by Mr. E. E. 
Green.

Sub-fam. Hchinopsocine, m. 
ao 
Echinopsocus, Enderl., 1903, and Scolopama, n. g.,form a perfectly 
independent group beside the Lepidopsocine ; I separate them on 
this account as sub-family Echinopsocine. In my opinion numerous 
forms belonging to this sub-family are still to be found in the Tropics ; 
but in consequence of their great inconspicuousness only two species 
have hitherto been collected. 
Fore wing with very long macrochete on the costal area and 
alsoon the veins and on the membrane of the marginal seam. 
Radial ramus simple (unforked) ; neither fused nor connected with 
the pterostigma. Pterostigma unusually large and very deep; 
both branches quite uncommonly long. Hind wings only very 
minutely developed (without venation) or absent. Antenne» 
multiarticulate (well over 30-jointed); the individual antennary 
joints of the flagellum are very short (antenne moniliform) little 
longer than thick, The wing scales are predominantly asymmetrical
