dark, broad line extends from the eyes to the clypeus. The anterior 

 ocellus is surrounded with black, and there is a pair of divergent 

 dark brown lines, a little curved, sending a 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, 

 and is pale horn color (testaceous), and unspotted. Labrum black. 

 Mandibles pale, pitchy. Antennae with the basal joint globular ; 

 the second a little longer, oval, both very much larger than the 

 sixteen succeeding pale horn-colored 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 

 antennae. Seen in front the difference between the eyes is equal to 

 the distance 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 tibise twice broadly ringed with 

 dusky ; tarsi pale. Prothorax very short, the tergum being trans- 

 versely linear ; mesoscutum cordate. Abdomen pale, almost whitish. 

 Upper wings regularly oval lanceolate, the tips being acute, but not 

 prolonged ; densely covered with hairs and scales, with the fringe 

 long on the outer half of the wing, and increasing in length towards 

 the tip so that the outline of the fringe is oval. Under the micro- 

 scope 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- 

 matidae and Poduridae, varying greatly in form, some being long and 

 narrow, with acute teeth on the outer edge, and a rather large 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. (See figure, 

 b, c, d, drawn to the same scale with the camera.) The wings are 

 glistening gray, and spotted irregularly with dark towards the tips. 

 Venation : in the fore wings (a) 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 dis- 

 cal 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 subdividing midway between the tip and the
