the ocellus the wings are crossed by a second double transverse band from the costa to the inner 

 margin, but this band is white on the inner side and black on the outer. 



"Hind wings similar to the fore wings, but without the transverse band at the base. Ocellus 

 very large, and outside the black ring are three more ; first a crimson one, then a pink ring, and 

 lastly an outside crimson one. Thorax and abdomen deep rufous chestnut. Underside similar 

 to the upper side, but the basal transverse band is absent in both fore and hind wings.

Imago. — -°. Head fairly prominent; front a little narrower than usual; the vestiture 

 closely cropped, coming to a point in front, and not concealing the palpi. 



Antennae of s with pectinations of moderate width, tip filiform. Those of the 9 with 

 short joints, not quite so long as wide; one pair of pectinations to a joint; no traces of a distal 

 pair; the pectinations about four times as long as the joint itself. Palpi short, small, weak, 

 depressed, not reaching near the front; composed of but a single joint, which when denuded 

 is seen to be only about three times as long as thick; the terminal scale scraggly, unequal. 

 (Besides these there is a distinct tuft of scales on each side of the mouth, and below the orbito- 

 lateral foramina, which are open and distinct, being situated near the site of the atrophied 

 maxillae of which there are no traces.) 



Thorax and body moderately stout; vestiture moderately abundant and long. Fore 

 wings large, triangular; costa moderately arched; apex somewhat rectangular; the wings not 

 falcate in either sex; outer edge moderately full, not excavated, about equal in length to the 

 inner edge. Hind wings with the apex moderately rounded; outer edge moderately full, only 

 slightly convex; inner angle almost rectangular; inner edge very long and straight, and reaching 

 far beyond the end of the abdomen. 



Venation: Approaching that of Nudaurelia and Lobobunaea; the origin of the first sub- 

 costal vein (vein UJ situated in front of the middle of the discal cell, and just before the origin 

 of the common stalk of vein II, and II 4 ; vein II 2 minute, vestigial, forming a slight tooth-like 

 projection, not reaching near the costa; vein III 3 detached and partly independent, more 

 detached than in Nudaurelia or Lobobunaea. Discocellular veins collectively forming a straight 

 line, much as in Nudaurelia and Lobobunaea, but not even slightly curved. 



Hind wings much as in the genera mentioned. 1 



Markings: Ground color of body and wings dull snuff-yellow, with dull brick-red lines and 

 shades, clear moderately large discal somewhat lunate spots on each pair of wings, but they are 

 not encircled by bright shiny lines, only a single dark reddish ring. 



Larva. — Not known. 



Pupa. — Dr. Holland has figured the pupa, and has stated "the fact that the chrysalis is 

 suspended, and while the caterpillar weaves a few stout silken threads about the spot where it 

 undergoes its transformations, the chrysalis hangs pendulous from its support like the chrysalis 

 of the Nymphalidae." 



1 An interesting peculiarity in my single specimen is that the basal portion of the vestigo of vein in, in the discal cell, is thick and like the bases 

 of the other veins; this seems to be a case of survival of a portion of this vein, which in the Paleolepidoptera ( Micropteryx) and the generalized Neole- 

 pidoptera (Hepialidfc) forms a true well-developed vein, dividing the discal cell into two divisions.
