80 MECOPTERA AND PLANIPENNIA 
Genus Leucochrysa Mac Lachlan (1868). 
Mac Lachlan, Transact. Ent. Soc. Lond. 1868, p. 208 (1868). 
This genus comes by its smaller size and narrower wings 
nearer to Chrysopa. It is easily distinct from it by the 
very long antennae and the parallel, very distinct cubiti 
of the forewings, which are distinctly connected at their 
tip in the disc of the wing. It is distinct from Apochrysa 
by the exterior row of gradate veins, which is oblique 
and straight and does not distinctly reach the tip of the 
radius and subcosta; the wings are much narrower. 
The genus is known from the tropical regions and is 
represented in Insulinde by:

I examined Albarda’s type, an immature &' from Moeara 
Laboe, November 1877, and a mature one from Sumatra 
(Ludeking).
