56 MECOPTERA AND PLANIPENNIA 
The eggs of Chrysopa are remarkable by the long stalks 
and are deposed in groups at twigs. Those of other genera 
are unknown. The larvae live in the same way as those 
of the Hemerobidae and are also useful. 
Numerous species occur in Insulinde and no doubt there 
will be discovered many more. They belong to the following 
genera: 
Costalfield in the forewings strongly dilated at the base, 
hindwings much narrower than the broad forewings. 
Antennae as long as the forewings or a little shorter. 
Ankylopteryx Brauer. 
Costalfield of the forewings not much dilated at the 
base, hindwings not much narrower than the forewings. 
Antennae mostly longer than the wings. . . . 1. 
1. Male with elongate app. sup. forming a forceps. 
Chrysocerca, nov. gen. 
Male with short valvular app. sup. . . . . . 2 
2. Cubiti parallel, very distinct and united at their tip. 3. 
Cubiti divergent towards their tip and not or indis- 
tinctly united.at ‘ther tip, … ts 
3. Large slender species with broad wings, the tip of the 
united cubiti and that of the united radius and sub- 
costa connected by a curved line of gradate veins in 
both wings. The wing is distinctly divided into a 
discal and a very broad marginal part. Antennae very 
long, much longer than the wings. 
Apochrysa Schneider. 
Mediocre species, with the cubiti only distinctly united 
in the forewings, less distinct in the hindwings, not united 
by a series of gradate veins, though such are developed 
as a continuous oblique series towards the tip. Wings 
narrower, no division of discal and marginal part. 
Leucochrysa Mac Lachl.
