HESPERIID^E.

genitalia of these two Skippers, and have no doubt whatever that they are distinct species ; but 
until the genitalia of other allied species have been worked out it is useless to give a new specific 
name. The species Fig. 4 on PI. Vila, is as common here as B. mathias, and often swarms 
in the autumn. The chief external difference between the two species shown at Figs. 3 and 4 on 
PI. Vila, is that Fig. 4 has no spots in the sub-median interspace, and the upperside of the 
hindwing has the spots usually quite distinct; Fig. 3 has a spot in the sub-median interspace, and if 
any spots show on the upperside of the hindwing they are not more than two in number and are 
very obscure. 
Baoris assamensis, de Nicev. 
This fine Skipper is not uncommon here during the wet season and on into late autumn. 
I found it common at Wuchow during July, frequenting flowers in the late afternoon and evening. 
It flies very swiftly and does not linger at a flower more than a few moments, feeding almost like 
a Hawk-moth, and producing a humming sound with its wild rush through the air. This Hes- 
perid varies slightly in the distinctness of the spots on the wings, but usually they are almost white 
and well defined. It seems to be a decidedly crepuscular species, and in this district frequents 
Lantana flowers. 
Fig. 5, PI. XIV is from a taken in August, but the sexes are very similar. 
Baoris oceia, Hewitson 
A fairly common species here, and on the wing practically throughout the year. It is, 
however, easily confused with other Hesperids unless closely examined. It frequents the under¬ 
growth beneath trees, and shady gardens, and is attracted by Lantana and other flowers. It flies 
rather swiftly but apparently does not usually wander very far, and like many other Hesperids often 
rests with semi-closed wings on leaves and twigs, whence it darts away on excursions, returning 
very often to the same perch. The sexes are almost identical in colour and marking, but the $ 
has a tuft of long dark brown shining hairs springing from the disc, cell on the upperside of the 
hindwing, and'is easily recognised thereby. 
Fig. 8, PI. XIV is from a taken in February. Baoris oceia varies slightly in the 
number or distinctness of the spots in the forewing: often there are only two instead of three small 
sub-apical spots close together; sometimes there is a small but distinct spot in the median interspace 
close to the sub-median nervure. There are no spots in the hindwings of either sex. 
Larva, when young of a pale yellowish-green, whitish towards the last segments. Second 
segment yellowish-white. Head small and black. Fullgrown, smooth or in places finely wrinkled 
transversely, general colour yellowish-green whitish towards the last segments, and with a lateral 
band of whitish each side, just above the prolegs. Underside glaucous green; legs and prolegs 
greenish-white. Head large and whitish, ringed with black round the edge, which broadens on 
the sides of the face near the jaws. Suture marked broadly with black down the upper part of the 
face; a triangle just over the jaws formed by thin, double black lines, with one short central line.
