FASCICULI MALATENSES 
1 1 
The median sector arises beyond the level of the vein descending from 
the nodus, the sub-nodal sector still further beyond this. Post-nodal nerves 
eleven to fourteen, usually twelve. The head of the male is much shrivelled ; 
in the females the upper lip is black with a pair of ill-defined bluish marks near 
its base ; rhinarium pale blue, the rest of the head black except the labium and 
under-surface which is yellow. 
Prothorax pale yellow, the hinder lobe steely-black. In the male the 
posterior lateral angles of this lobe are almost squared and project slightly out- 
wards and backwards. In the female these angles are produced into a short 
outwardly projecting spur on either side, which, like the lobe itself, are of a 
steely-black colour. Thorax black on the dorsal side, this colour extends 
laterally as far as the humeral suture ; the sides are a pale-yellow, with an 
oblique wedge-shaped mark on the first lateral suture, its apex directed down- 
wards, not reaching to the base of the legs. 
Abdomen dark brownish-black. The first segment is yellow with a dark 
apical ring in the male. Segments two to seven each with a basal ring of pale 
yellow and an apical ring of jet black. Segments eight to ten short, sub-equal 
dark-brown. 
The above description applies equally to either sex apart from the dis- 
tinctions noted. 
In the older of the two females, that from Bukit Besar, the light and dark 
basal and apical rings extend only to the fifth segment. 
Length of abdomen $ , 4.2 mm. ; of hind-wing, 23 mm. 
» „ 9,34 mm.; „ „ 24 mm. 
The disproportionate length of the abdomen of the male is no doubt due 
to the fact that it has been subjected to some pressure in packing, and to its 
very delicate state. 
The anal appendages are much shrivelled, so that it is not possible to 
describe them ; the lower pair appear to resemble those of P. quadrata.

Two adult males from Kwala Kangsar, Perak (Coll. Forster). 
Disparoneura notostigma. de Selys. 
De Selys versuchte zuerst seine beiden Gattungen Disparoneura und 
Alloneura ( Caconeura , Kirby) dadurch zu trennen, dass er den achten 
Disparoneuren getrennte Sectores arculi zuschrieb, seinen Caconeuren an der 
Basis ein Stuck weit verschmolzene Sectores arculi.
