interspace a grey area, and thence to the anal angle a blackish line, inwardly bordered with 
reddish ; ci/ia basally grey, outwardly dark.” 
“From PF. phalena, Hewitson, from Singapore, of which it seems to be the northern 
representative,* it differs in the narrow streak below the cell in the forewing, with the 
bifid spot beyond it, and in the long mark in the hind margin, The hindwing below is 
quite different, much less white, the discal spots larger and of the general ground-colour, 
the submarginal spots absent, and the apical rufous-brown space greatly reduced.” 
‘*The generic characters resemble those of P. ewitsoni, Moore. The left forewing: 
has the first subcostal nervule rather more slender and further from the base of the second 
than in that species, In the right forewing the first subcostal nervule is wholly absent. 
This interesting aberration may be of frequent occurrence in this group, and may have 
been the cause that Moore, Hewitson, Felder and Distant passed over this vein in their 
descriptions of the genus.” 
‘©The egg probably agrees with that of the other species of the subfamily. It is a 
truncate pyramid nearly twice as long as wide, with two vertical and two sloping sides, 
the former trapezoidal, reticulate near their upper edges; the latter and the apex nearly 
square, delicately reticulate. In the ovarian tubes of the female, these eggs are found in 
pairs, attached by their bases. Along with those of Lifhyra brassolis, Westwood, they are 
the most remarkable eggs in the family.” 
«<The chrysalis somewhat resembles those of the Zrycinide [= Nemeobiina] and strikingly 
illustrates the singularity of the group. It is suspended, not girt, but rigidly inclined towards 
the surface of the leaf. It is less compact in form than that of other Zycenide, and is 
studded with bristles. Of these a number on the side of the head are white, with two black 
ones on each side of the top of the head, and one black one on each side of the thorax above 
the thoracic angle. The second, third, and fourth abdominal segments have each a lower 
white and an upper black bristle approximate laterally ; while the last segments have a 
number of white lateral and of black subdorsal ones. ‘The ground-colour is ochreous, 
much marked with dark, especially on the upper surface of the abdomen ; each segment 
having a black line near its hind margin, except the first which has two distinct black 
spots dorsally. The wing-covers are veined and bordered with brown.” 
«‘I name this species for my fellow traveller in Assam, Lieutenant Ernst Hartert, the. 
ornithologist and African traveller, who obtained the sole specimen.” (Doherty, 1. c.)

This species must be very rare, none seem to have been obtained since Mr. Wallace procured the type.
