prothorax, which is unicolorous yellowish green like the 
body and legs. The antennae are much longer than the 
forewings and of the same colour. 
The wings have the same form, but the forewings have the 
following black markings. The exterior row of gradate veins 
is much darker infuscated and the fuscous colour is some- 
what flown out towards the apex along the longitudinal 
veins. Three apicalveins between the radius and its sector are 
united by erossveins and darkly suffused with black, and 
the third marking is the crossvein between postcosta and 
cub. inf., which latter is broadly bordered with black. 
The hindwings have no markings. 
Body 10 mm., forew. 17 mm., hindw. 15 mm., ant. 26 mm. 
Abd. 6 mm, gr. br. 6; mm., gr. br. 5 mm. 
Habitat: Java. 
I examined Gerstaecker’s type, a female from West Java 
(H. Fruhstorfer), an immature specimen from East Java, 
6000 ft, from the same collector, and a { from Java, old 
collection, named by Dr. S. C. Snellen van Vollenhoven 
Chrysopa longicornis. 
The antennae of both types of Gerstaecker are broken 
off at the tips, so that the measurement 19 mm. is wrong. 
Genus Apochrysa Schneider (1851). 
Schneider, Monogr. Chrysopid. p. 157 (1851). 
To this genus belong the largest and most beautiful 
species of Chrysopidae. It is nearly related to Leucochrysa 
and also characterised by very long antennae. The wings 
however are much broader and characteristic by the exterior 
row of gradate veins, which forms in the forewing a curved 
line that connects the tip of the united cubiti with that 
of the united subcosta and radius. In the hindwing this 
character is less conspicuous. The species remember in their 
habitus much the genus Myiodactylus. | 
It has the same distribution as Leucochrysa and the 
following species exist in Insulinde:
