there are no less than 28 species belonging to the family. Chrysopa is the chief
genus, with C. notata Walker the commonest species. C. flava (Scop.) also occurs
there.
Nothochrysa ins ignis Walker is one of the largest species, and Dictyochrysa
julva E. Petersen is a distinct Australian species with a regular network of
similar wing cells. Japan is rich in members of this important family, having at
least five genera and many species including the European Chrysopa vittaia
Wesmael.
The beautiful South American Loyola crassus Navas with a wing expanse of
65 mm. is probably the largest species in the family, and Nott'obiella unila
Banks, of Australia with an expanse of only 8 mm. is one of the smallest.
Other important genera are Allochrysa Banks, Meleoma Fitch, Leucochrysa
McLachlan, and Eremochrysa Banks.
Family BEROTHIDJE Handlirsch 1908 (Ber-oth'i-dre, from the Greek {JEPO'!),
a nymph). Beaded Lacewings.
The adults are small and slender with long filiform antennre and without
ocelli; the wings are variable in shape, hairy, and often with peculiar seed-like
scales attached to the important veins of the females. The eggs of SpermophoreZla
are elongate and raised on stalks, thus resembling those of Chrysopa.
They usually occur in groups in the larval habitat. The larvre are thysanuriform,
with short straight mandibles and maxi11re. Those of Spermophorella
disseminata Tillyard live in sandstone caves in New South Wales, Australia,
and are suspected of preying upon caterpillars which live on the lichens in and
about the caves. As a matter of fact, little or nothing is known concerning
their biology.
This small family consists of some 10 genera and 30 species which are scattered
in Asia, Africa, Australia, New Zealand, and North America. Eight species
live in Australia and one in New Zealand. The genus Berotha Walker is
Indo-Malaysian, Cycloberotha Tillyard and Spermophorella Tillyard are Australian,
and Lomamyia Banks is North American. The latter has two species,
L·flavicornis Walker, in the eastern states and L. texana Banks, in the western
states.
Family DILARIDE Handlirsch 1906 (Di-lar/i-dre, from the Greek aLs, doubly,
+ ).,apos, pleasant to the eye). Pleasing Lacewings.
Small insects in which the veins and cross veins of the wings have numerous
branches around the margins. The three ocelli are tuberculate and prominent.
The antennre of the males are pectinate, and the females have an exserted ovipositor.
This is a small family of some six genera and 30 species occurring in Europe,
Asia, Africa, North America, and South America. The most important genera
are Dilar Rambur, Lidar Navas, and Nepal Navas. Dilar americana McLachlan
is North American, and D. japonica McLachlan is Japanese.
