84 LEPIDOPTERA. 



pectination bears two short hairs of the same colour, 

 each of these hairs is finely pubescent at the side. The 

 female is almost without pectinations. 

 Rufaria. Antennge whitish-yellow, consisting of conical 

 joints, which are at their ends clothed around with little 

 hairs, and are only perceptible in the male when highly 

 magnified; the antennce of the female appear to be 

 perfectly smooth. 

 The anterior wings of the male of perochraria are pointed 

 at the apex and the hind margin is slightly rounded ; those 

 of the female are more sharply pointed and the hind margin 

 is almost straight. The head, thorax, abdomen and all the 

 wings are of various shades of ochreoas-yellow in the male 5 

 in the female, which is always smaller, they are paler; the 

 cilia are generally brown-grey, sometimes iron-grey and not 

 rarely ochreous-brown. Of the three ochreous-brown trans- 

 verse lines, the first is curved, the second nearly straight, 

 more resembling a '' central shade," stands exactly in the 

 middle and in it is the black-brown central spot, which how- 

 ever is in most specimens wanting ; the third, consisting of 

 several small indented curves, is generally the darkest and is 

 outwardly margined by pale ochreous spots. Near the dark 

 hinder margin is an indistinct pale ochreous indented line, 

 almost parallel to the third transverse line; it somewhat 

 resembles a fascia composed of spots. Before the cilia we 

 sometimes see small black-brown streaks, more frequently in 

 the female. 



The posterior wings only bear two transverse lines, between 

 which stands the rarely absent black-brown central spot; in 

 other respects they are marked as the anterior wings. 



In many specimens the transverse lines on all the wings 

 are hardly perceptible. 



The underside is just as variable as the upperside ; there
