areas only. Rostrum barely reaches posterior coxae. 
Opercula narrowly margined with piceous on inner 
margin, broadly at apex. Distinguished from preceding 
species by green ground-colour of opercula, whose 
inner margins do not meet. The mesonotal markings 
are also different. Ground-colour of mesonotum is red 
brown and the black fasciae are more slender by half. 
The ground colour of pronotum is light olivaceous 
brown like the ground-colour of both pronotum and 
mesonotum in C. agatha. 
Habitat : Borneo. Mt. Kina Balu (Whitehead); Sara¬ 
wak : Baram Point, Kcdurong and Kuching—several 
specimens (Sar. Mus.). 
9.— Cosmopsaltria alticola, Distant. 
Trans. Ent. Soc. LoikI. p. 200 (1905). 
I have not seen this species, but Distant notes that it 
is allied to C. montwaga . The following two points 
mentioned in his description serve to separate it from 
all the other Bornean species :—(1) opercula reach the 
fifth segment of abdomen only (C. jacoona, Dist. is the 
only other Bornean Cosmopsaltria thus characterized), 
(iij tegmina infuscated on veins at base of 2nd, 3rd and 
5th apical areas—a unique feature among the above 
s-pe.cies. 
Habitat : Borneo. 
The following synopsis—artificial as all such keys 
must be—shows more clearly how the above species 
may be differentiated, besides suggesting their relations 
to one another.
