Mr. J. J. Walker on 
of my Hong-Kong specimens of this insect in the 
National Collection, placed under M. drusia^ Cram., 
which was originally described from China, and is pro- 
bably only a race of M. mineus. 
14. Lethe europa, 
Papilio europa^ Fabr., Syst. Ent., p. 500, n. 247 (1775). 
Moderately common in bushy places, in "Happy 
Vallej^,^' at Kowloon, and elsewhere. It has a wild 
aud rather strong flight, and, contrary to the general 
habits of the Satyridse, it often settles on the leaves 
and twigs of trees for a few feet above the ground. A 
light fawn-coloured variety of the 6 occurs rarely. 
First taken by me 25th March, 1892 ; more common 
in May. 
15. Lethe verma. 
Satyrus verma, Koll., Hiigel's Kashmir, iv., 2, p. 447, 
t. 16, fig. 12 (1848). 
Of this pretty little species I have met with but one 
specimen, at the exuding sap of a small tree in the 
" Happy Valley,'' on the 17th March, 1892, and have 
seen one or two others in local collections. 
16. Ypthima huhneri. 
Ypthima huhneri, Kirby, Cat. Diurn. Lep., p. 95 (1871). 
Papilio philomela^ Hiibn. (nec Linn.), Zutr. Ex. 
Schmett., figs. 83, 84 (1818). 
Not rare, among long grass on the hillsides, as well as 
in gardens and woody places. It may be found from 
December to May. 
17, Ypthima argus. 
Ypthima argus, Butl., Journ. Linn. Soc, Zool. ix., 
p. 56, n. 22 (1866). 
Much less common than the preceding species ; I have 
found it rarely in " Happy Valley/' in February and 
March.
