SCALY WINGED COPEOGNATHA. 53 
Outer border of the wings between the ends of m, and m, with 
an outgrowth (6), which in the female is produced into a more or 
less long and acute tail-like process. It is remarkable that in this 
case the female is characterised in such a marked manner. 
There is no pterostigma since the distal portion of the subcosta 
is lacking. Stigma sac distinct. Median branches very long. 
Areola postica elongated. Two axillary veins. - 
In the hind wing, an and ax end rather near to one another ; 
media simple. In the fore wing between the scales are numerous 
very fine hairs. 
Scales slender, sides nearly parallel, ends rounded (fig. 42). 
Marginal scales (fig. 42, rs) very slender, truncate at the end. Scales 
of the hind wing (fig. 43) very slender, with two long acuminations 
at the end, which become shorter towards the margin of the wing. 
Three relatively large species from Ceylon. 
It is thus established with certainty that this important genus. 
does not belong to the Lepidopsocide (cf. Enderlin, 1903) ; it is, on 
the contrary, a typical Amphientomid.

bands, gold markings, and a large orange 
yellow or gold spot in the anterior half of 
the apical quadrant .. Brat 22 
Fore wings with numerous fine, sinuous, 
closely arranged golden cross-bands ;

dark brown longitudinal bands .. ritusamhara, n. sp.

between the eyes ae .. caudata, Hag., 1865. 
Vertex with two fine parallel dark brown 
cross bands between the eyes .. erato, n. sp. 
Syllysts erato, n. sp. (figs. 2, 37, 38, 42, 43, 55, 95, 102). 
Head whitish grayish yellow, glabrous. Across the vertex, uniting 
the eyes, are twonarrow parallel dark brown bands, leaving an equally 
broad tract between them ; the anterior band placed at the front 
margin of the vertex, runs through the two posterior ocelli and is 
feebly notched (concave forwards) in the middle ; the hinder band 
is indistinctly concave forwards. Occipital border, sharp edged, the 
edge rounded, somewhat concave, Suture of vertex very fine, some- 
times almost invisible ; suture between vertex and front distinct. 
Front remarkably elongate and very flat. Clypeus relatively small
