SOME NEUROPTERA FROM AUSTRALIA.
BY NATHAN BANKS,
East Falls Church, Va.
From Professor Perkins of Hawaii, and +Mr. Dodd of Kuranda, Queensland, 1 have received a number of Australian Neuroptera. The Chrysopidte and a few other forms are described in this article. There are four genera of Chrysopidce in Australia; Chrysopa, Nothochrysa, Ankylopteryx, and Apochrysa. The first two occur in the United States, but Nothochrysa only in California. As with us Chrysopa is the largest genus, and some of the species are very similar to some of our forms.
Chrysopa.
The Australian forms known to me can be distinguished by the following table :
1. Dark marks on the vertex.. ............................. .C. ramburi No marks on the \rertex .......................................... 2. .................................................... 2. Veins all green 6.
............................................... Veins partly black.. .3.
3. A black spot on the radial sector, shortly before the stigma C. signatipennis
....................................................... No such spot 4,
4. Many veins more or less margined with dark.. .................... .5, Veins not margined.. .................................. .C. innotata 5. A band across the face.. ............................. C. irregularis No band across face ....................................... C. regularis ...............................
6. Basal part of antennze blackish.. -7. ................................................... Antenne all pale 8.
7. Vertex mostly red, face reddish.. ........................ .c. atdotis Vertex yellowishy a transverse red stripe over base of antennze from eye to eye ................................................ C.satilota 8. Divisory veinlet commonly ending before the cross vein; wings long, slender, awte ............................................ C. otalatis Divisory veinlet ending beyond the cross vein.. .................... ,9. 9. Larger species; stigma indistincty vertex reddish; wings very narrow C. italotis
Medium speciesy stigma not very distinct; vertex pale; wings quite broad ................................................... c. latotalis Smaller species, a reddish spot on vertex, stigma of hind wings very prominent ................................................ C. ohtatis
