27. Ajpatura parysatii^. 
Apatura pary satis ^Weatw., Gen. Diurn. Lep., ii.j p. 305 
(1850). 
Jsot uncommon in the Happy Valley/^ in March, 
April, and May, the almost black S delighting to sun 
itself with expanded wings on the outer leaves of low 
trees, the paler-coloured ? being more partial to shady 
places. 
28. Hestina assimilis. 
Papilio assimilis, Linn , Mus. Ulr. p. 300 (1764) ; 
Syst. Nat., i., 2, p. 782, n. 194 (1767). 
This very handsome butter% occurs rather sparingly 
in the Happy Valley'^ and near Kowloon, in April and 
May, and sometimes earlier ; I took my first specimen 
on April 2nd, 1892. In the Chusan Islands, where it is 
common, it frequents the tops of the hills at an elevation 
of 1200 to 1500 feet, and settles on the bare hot rocks 
with wings fully extenJe>-d. Although a strong flyer it 
is not shy, and is caught without much difficulty.

Not very common in Hong-Kong, but rather more 
plentiful at Kowloon, where Mr. Skertchly found it in 
beautiful condition at the end of April, 1893 ; my first 
specimen was taken May 7th, 1892. A specimen was 
bred by Surgeon- Captain W. W. Beveridge, from a 
smooth green slug- like larva with two branched horns on 
the head (not very unlike that of Apatura iris), which 
changed to a very stout green pupa. 'J^he flight of this 
butterfly is graceful and floating, usually rather high, 
but I have more than once seen it settle abruptly on the 
ground in the middle of a road.
