OF INSULINDE, ef 
Abdomen black in the 7, the process of the third tergit 
is somewhat broader in its latero-basal part and the 
tubercle of the fourth is somewhat higher. The seventh and 
eighth segments are relatively shorter. The ninth (fig. 5) 
is somewhat shorter pedunculate and narrower, the tips of the 
forceps are more strongly crossed. The genitalvalves (fig. 6) 
are in lateral view narrower and acutely angulate at the tip. 
The wings are of the same colour and form. The tips

One male from Central Java, Semarang Residency, Mount

its collector. 
Genus Leptopanorpa Mac Lachlan (1875). 
Transact. Ent, Soc. Lond. 1875, p. 187 (1875). 
This genus is merely based upon the characters of the cj’ 
and is characterised by the slenderness of all parts. The 
body is very long, the basal segments of the abdomen are 
long, the 3 terminal ones very long and thread-like, the 
cheliferous segment is elongate-pedunculate. The wings are 
very narrow and the rostrum and legs are exceedingly long. 
An approach and rather a transition to this genus form 
species as P. nematogaster and jacobsoni, but the ninth 
segment is here sessile or shortly pedunculate. 
The typical species ritsemae and sieboldi occur in Japan, 
and in Insulinde this genus in represented by the following 
new species: |
