OF INSULINDE. 51 
Habitat: West- and East Java. 
Gerstaecker only described males, as the female has no 
tubercle and its wings are somewhat darker spotted. I 
examined a female from Java, previously named by Mr. 
Snellen van Vollenhoven as O. variegatus, and a male from 
Central Java, Ambarawa, collected by Ludeking. The species 
is nearly related to the indian O. conspersus Wlk. of which 
O. tuberculatus Wlk. is very probably the male, and to 
O. interlineatus Mac Lachl. from India or Natal. 
Osmylus inquinatus Mac Lachlan. 
Osmylus inquinatus Mac Lachlan, Ent. monthl. Mag. VI, p. 200 
(1870). Ceram. 
Of the same group as O. modestus Gerst. and probably 
also a subspecies of it. As I have not compared the 
type-specimen, which is specially compared with O. inter- 
lineatus Me. Lachl., likewise unknown to me, I only 
can give an incomplete description compiled from the 
original one. 
Very characteristic is the golden pattern of the forewing. 
Antennae yellow, legs pale yellow, anterior and median 
tibiae with 3 black spots externally. Prothorax stout, rather 
longer than broad. 
Wings rather long, the apex acute, the apical margin 
straight, membrane greyish hyaline; pterostigmatical region 
with a black spot on each side. Neuration mostly black, 
here and there white. Subcosta and radius in the anterior 
wings whitish, subcostalfield with two short golden trans- 
verse fasciae, a point of the same colour between them 
and two ditto streaks towards the apex. There is a rounded 
raised spot on the hind margin of the forewing at about 
one third of its length from the base. 
Body 4 lines, expanse of wings 19 lines. 
Habitat: Ceram. 
The type, a specimen collected by Wallace, is in the 
British Museum. I have not seen other specimens of this 
species.
