LANUGO herance, which gives it a bunched or humped look. There are several tubercles and lines on it of a reddish colour. The ground colour is an olive brown; and underneath, it has one larger rib running all the way along it from end to end, dividing it in two; and by the sides of that there are some others. These are all reddish, and those nearest the edges have small rows of spines running along them. Over each of the eyes there is a round granulated prominence, which seems to have been a collection of smaller eyes; and if so, the animal is supplied with the organs of vision in a different manner from all other known creatures. But an examination of the creature on the spot, and while alive, is requisite to find out this. The upper pair of wings is not perfectly transparent; they are dotted with white in some places, and are variegated near their origin with several blackish spots. The under pair are more transparent than the upper; they are much shorter and broader than the others. These have each a large and beautiful round spot near the extremity, resembling that on the wing of the peacock butterfly. The colours of the circles of these eyes are brown and olive; the last colour very bright and clear, the other very dusky and obscure. The spots are so large, that they appear very beautiful.
