HESPERIIDJE. 
Iambrix salsala, Moore 
A fairly common Skipper on some parts of Hongkong island, but it does not seem to 
occur on the Kowloon side, nor at Macao. It is common in places in the woods at How-lik, 
frequenting grass and low herbage in damp places under trees. It also occurs at Lo-fu-shan. It 
has not a particularly fast flight, and constantly returns to special leaves and sprays on which it 
rests, never seeming to wander very far. The sexes are much alike.

the wet season, and late in the autumn. 
Hyarotis adrastus, Cram . 
This species is common at Hongkong in some places, but I have not observed it at 
Macao. On the wing it may easily be mistaken for Notocrypta feisthamelii. It has a rapid 
flight but often rests on foliage, stones, etc., and sometimes returns again and again to the same 
spot. Like many other Hesperids it has a predilection for settling on bird-droppings and sucking 
moisture therefrom, and is often deceived by other small whitish substances. Hyarotis adrastus 
is common by the side of the stream running through the woods at How-lik. 
Fig. 4, PI. XIV is from a £ taken in May, but this species occurs throughout the wet 
season and late into the autumn. The sexes are very similar. 
Matapa aria, Moore 
This seems to be a very common Hesperid over most of Kwangtung, occurring in 
numbers in almost every little wood when bamboo is growing anywhere near. Its plain and 
sombre colouring is relieved by the beautiful crimson eyes, which retain a certain amount of colour 
for some months after death. The flight of this species is not quite so rapid as that of most 
Skippers ; though it is to be seen feeding at flowers in hot sunshine it prefers undergrowth beneath 
the shade of trees. 
Fig. 24, PI. XIV is from a $ taken in May, but it is to be found on the wing almost 
throughout the year. The sexes are practically alike, but the $ occasionally has a whitish brand 
across the interspace between the median nervule and sub-median nervure of the forewing, as in 
the $ of Parnara mathias. 
Egg, hemispherical, smooth, whitish ; laid singly either side of the leaves of scrub 
bamboo, the foodplant of the larva. 
* Larva, very young, smooth and shiny, reddish changing to greenish near the head. 
Head black. Later, general colour greenish, the second segment rather swollen and yellow. 
Fullgrown, almost cylindrical instead of the usual fusiform type ; of a general chalky yellowish- 
white. The spiracles marked in black, the last spiracle boldly marked in black. A thin transverse
