62 MECOPTERA AND PLANIPENNIA 
Genus Chrysopa Leach (1815). 
Leach, Edinburg Eneycl. IX, p. 138 (1815). 
This cosmopolitan genus is characterised by moderately 
long antennae, which are about as long as or a little longer 
than the forewings. Wings moderately broad, nearly equal 
in size. The cubitalcell is triangular and connected at its 
tip with the ramus divisorius. The cubiti are not united 
at their tip and rather divergent. Body moderately stout, pale 
green with some darker points on head and thorax in some 
species. In one species the wings are coloured with fuscous 
and dull golden markings, in most others they are hyaline. 
The development and biology of some species are known. 
The following species occur in Insulinde:
