_Upper Side._ Antennæ strongly pectinated; the extremities appearing like threads. Thorax light brown, tinged with red. Abdomen grey brown. Anterior wings light grey brown, tinged with red at the base; having a narrow dark-coloured bar verged with grey running from the anterior to the posterior edges, parallel and at a little distance from the external margin. Posterior wings grey brown, terminating behind in points like acute angles; a dark narrow bar, edged with white, crosses these wings from the upper corners to the abdominal edges, dividing them into two compartments; in the uppermost of which are placed two eyes, whose centres are yellow, surrounded with black irides edged with red, and which also are encircled with ash-coloured rings. Above these eyes the wings are dark-coloured, almost black; but next the body are of a reddish hue. _Under Side._ Legs black. Thorax and abdomen same colour as on the upper side. Wings nearly the same colour as on the upper side; the bars being plain and distinct, but the eyes are not observable here. DRYOCAMPA VIRGINIENSIS. Plate XIII. fig. 2. ORDER: Lepidoptera.
