Rhopalocera from the Australian region. 157 
heard of immense flights of white butterflies having 
occasionally been seen in Queensland, proceeding at a 
considerable height from east to west, and should think 
it likely that they were this species. 
On May 15th, 1882, i noticed a female fluttering about 
the topmost shoots of a small bush of Capparis lasiantha, 
R. Bth., and upon examination discovered hundreds of 
egos, laid in batches of a dozen or more; they were of 
the usual Pieris type and bright straw-yellow. There 
were also numbers of larve of all sizes, but none of 
them appeared to be quite full-grown. I took a few of the 
largest. A day or two afterwards, while picking some 
fresh food for these larvee, I found a number of empty 
chrysalids, two of which had the freshly-emerged butter- 
flies sitting drying their wings alongside of them. I also 
picked two which had not come out, and which appeared 
a few days after in my cabin. When full-grown these 
larve appear to wander, for I noticed several empty 
chrysalids upon adjoiming shrubs. The tree these larve 
were upon was rather a stunted unhealthy-looking one 
of its kind, and, although there were others close at 
hand in a flourishing condition, I could not detect that 
they had been in any way touched. This peculiarity I 
have noticed with other species. From January 4th to 
20th, 1888, larve and chrysalids were in immense 
numbers upon three kinds of caper, Capparis nobilis, 
Muéll., C. Mitcheli, Lindl., and C. lasiantha, R. Benth., 
and I bred a large series of the butterflies. 
The full-fed larva is cylindrical, and tapers at each 
extremity, especially the anal; head somewhat cordate, 
black, with a few minute yellow dots and scattered 
whitish hairs, and a white \V/-shaped mark on the 
face; whole of the upper surface, which is glaucous, 
dark olive-brown, thickly irrorated with very minute 
yellow dots ; on the second segment, immediately behind 
the head, a series of three raised gamboge-yellow dots 
on each side of the dorsal vessel, and a single dot below, 
the whole forming a narrow ring; from each of these 
dots spring minute whitish hairs; on the third and 
fourth segments a row of six dots encircling the dorsal 
area; from the fifth to the twelfth segments inclusive 
these dots are arranged in a triangular pattern, and on 
the thirteenth segment they form a small patch, with 
two additional dots, which are rather conspicuous just
