SCALY WINGED COPEOGNATHA. 105 
branch up to the anterior ocellus. Two curved dark brown broad 
short bands just above the clypeus. The clypeus is free, raised 
above the surface of the front, andis pale horn colour (testaceous) 
and unspotted. Labrum black. Mandibles pale, pitchy. Anten- 
ne with the basal joint globular ; the second a little longer, oval, 
both very much larger than the sixteen succeeding pale horn-coloured 
joints, the latter being slender, gradually increasing in length to the 
tip, each joint provided with four or five long stiff hairs, giving a 
verticillate appearance to the antenne. 
‘* Seen in front the difference between the eyes is equal tothe dis- 
tance from the vertex to the base of the clypeus, the front being 
equilaterally triangular. Legs testaceous, the femora pale at base ; 
beyond a little dusky, the tibize twice broadly ringed with dusky 
tarsi pale. 
‘* Prothorax very short, the tergum being transversely linear ; 
mesoscutum cordate. Abdomen pale, almost whitish. Upper 
wings regularly oval lanceolate, the tips being acute, but not pro- 
longed ; densely covered with hairs and scales, with the fringe long 
on the outer half of the wings, and increasing in length towards the 
tip so that the outline of the fringe is oval. Under the microscope 
the wing membrane is covered with numerous dots, arranged in 
irregular wavy rows, the dots much thicker along the edges than 
elsewhere. In the middle and along the costa the hairs are developed 
into regular flat scales, like those of the Lepidoptera, and the Lepis- 
matide and Poduride, varying greatly in form, some being long 
and narrow, with acute teeth on the outer edge, and a rather long 
point of attachment ; others broad and short, with blunt teeth, and 
others more regular in outline ; all with shaded lines proceeding 
from each tooth and fading out towards the base of the scale. 
‘* The wings are glistening gray, and spotted irregularly with dark 
towards the tips. Venation: in the fore wings a minute, almost 
obsolete costal vein, four subcostal venules ; the main vein at the 
origin of the second branch anastomoses with the median vein, 
forming a long, narrow discal cell ; at one-third the distance between 
the anastomosis and the tip of the wing it sends off a third branch 
nearly equalling in length the two basal ones ; the median vein has 
five branches ; after sending off a branch to anastomose with the 
subcostal vein it subdivides, the upper branch again sub-dividing 
midway between the tip and the anastomosis. On the basal fifth 
of the vein a branch arises, which subdivides, forming the fourth 
and fifth median venules. A straight submedian vein is present. 
‘* Hind wings similar in form to the fore pair, but a little narrower ; 
a slightly marked subcostal vein, ending opposite the origin of the
