NEW NEUROPTERA AND TRICHOPTERA FROM THE 
UNITED STATES 1 
By Nathan Banks 
In the course of identification of Neuropteroid insects in the 
Museum of Comparative Zoology several species were found 
that are new. Descriptions of these are given, and further 
studies with additional material enable one to prepare a synop- 
sis of our small species of Myrmeleon. 
Order NEUROPTERA 
Chrysopid^ 
Chrysopa sperry ae sp. nov. 
Pale greenish; head, antennae, and legs more yellowish; pro- 
notum with a median yellowish stripe, extending back on 
mesonotum; both pairs of palpi marked with black, otherwise 
without dark marks, no dark nor reddish on cheeks. Wings 
with green venation, the only black is on the first (and some- 
times second) branch from cubitus to the cubital fork. Stigma 
long, plainly green. 
The fore wings have eleven radial cross-veins, six cubitals 
beyond the divisory cell, latter ending before cross-vein above; 
about six inner gradates and seven outer, the rows nearly paral- 
lel, each gradate separated from the next by more- than its 
length, except the two or three at upper end of outer row; hairs 
on veins about as in C. plorabunda. The costal area (at broad- 
est) almost as broad as the radial area, and each about equal 
to the post-cubital area, latter fully one-third broader than 
cubital area; subcostal area of stigma with but one or two cross- 
veins. 
In hind wings eight or nine radials; three inner gradates, 
and four or five outer ones, in nearly parallel series, and well 
separated.
