24 Mr. E. Doubleday on some new Diurnal Lepidoptera. 
All the wings of the male above white, the anterior with the base 
slightly irrorated with black, the costa narrowly black, the outer 
margin with a border of the same colour broad and deeply den- 
tate internally towards the apex, narrower and less deeply dentate 
towards the anal angle, median nervure and outer part of the 
subcostal black. Posterior wings white, with a narrow black 
border dentate internally, the base itself pale yellow, the space 
between the cell and the inner and outer margins as far as the 
cellular fold between the middle and outer median nervule bright 
luteous orange. Below, the anterior wings are fuscescent, with pur- 
plish and bronzy reflections, irrorated with yellow along the costa ; 
a vitta in the cell, a transverse macular band beyond it, and the 
whole inner margin as far as the cell white ; the apex with a short 
yellow band divided into three parts by the nervules. Posterior 
wings bright yellow, orange towards the anal angle, with a broad 
fuscous border in which is a distinct yellow spot towards the 
outer angle, and also some slight clouds of the same colour ; 
costal, subcostal and median nervures black. 
Female with the anterior wings above fuscous, the costa irro- 
rated with pale yellow, a vitta in the cell, five vittee beyond, of 
which the third is the shortest, a submarginal series of six not 
well-defined spots, and a spot on the inner margin yellowish 
white. Posterior wing yellow at the base and along the inner 
margin, the anal angle occupied by a large tawny brown patch, 
the outer margin broadly fuscous except at the anal angle, costal 
and subcostal nervules bordered with the same colour. Below, 
nearly as in the male, but paler. 
Head and thorax clothed with grayish white hairs; antenne 
black, ringed with white. 
Abdomen black above, side yellowish.

This beautiful species, of which I have only seen the pair in 
the collection of the Museum and a specimen sent from Borneo 
by H. Low, Esq., jun., is closely allied to Pi. Judith.
