A NEW SPECIES OF CORYDALUS 
(NEUROPTERA ) 1 
By Nath ax Banks 
Holliston, Mass. 
Corydalus ecuadorianus sp. nov. 
Head and pronotum nearly black ; meso-and metanotnm 
rather paler, pleura nearly black; legs brown to yellow- 
ish brown, bases of tibiae paler; abdomen black above, 
only a little paler beneath; antennae black beyond the 
first few rufons joints ; vertex with the smooth areas 
showing reddish as in cornuta, but reddish instead of 
yellowish; the smooth areas on pronotum, however, are 
scarcely paler than rest of surface. 
Fore wing heavily marked with dark brown to black, 
much broken up by pale and whitish areas, rarely round, 
mostly irregular; cross-veins black; costal area brown on 
basal half, but each cell has some pale in it, beyond the 
costal area is largely pale with black cross-veins, some 
bordered; behind there are some pale spots in nearly 
every cell, the largest between the medius and its branch, 
and two pale bands in the cell behind it, two in radial 
area toward tip are also fairly large, and an elongate one 
in radial area beyond the first radial cross-vein; also one 
behind the origin of radial sector and reaching across 
the medius. 
The hind wing is dark gray to brownish, but the apical 
half mostly brown, with black cross-veins, a square pale 
spot between second and third radial cross-veins, and a 
pale stretch in the subcostal area beyond, paler than in 
fore wing. Fore wing with about forty costals, in basal 
part several are curved, connected, or forked; the cross- 
vein from lower medius to cubitus is continuous with that 
from cubitus to cubital fork. In hind wing the first 
radial cross-vein (very oblique as in fore wing) ends at 
origin of second branch of radial sector, thus forming an 
X, and the second radial cross-vein does the same with the
