line, and on each side of posterior two-thirds is another pale 
stripe ; there is a short submarginal dark stripe on posterior 
part each side. Meso- and metanotum mostly black, more 
or less spotted with pale, mostly near middle; pleura dark, 
with a few pale spots below wings. Abdomen dull black 
the first, second, and basal half of third segments with a pale 
stripe each side above. Legs pale, the femora and tibiae with 
some black spots or bands, apex of tibia black, tarsi with the 
whole of the fourth joint, and the tip of the others black. 
Wings with the venation largely black, the subcosta much 
interrupted with snow-white, the radius less interrupted 
with pale, toward stigma the medius is white for a long dis- 
tance, cubitus interrupted with white, and also the radial 
sector; many cross-veins partly or wholly white. Along 
the cubitus and at intervals beyond it is bordered with black, 
and a longer black streak obliquely up from the rhegma ; at 
base of stigma and back on radius it is black. 
In hind wings venation mostly black, but subcosta and 
radius interrupted with pale. 
Pronotum much longer than broad, narrowed in front, 
the erect bristles are black, and short more appressed hair is 
white. Wings slender ; in fore wing three cross-veins be- 
fore radial sector, latter with six branches, some of the cos- 
tals forked before stigma, a few cross-veins in apical field, 
eight or nine cubito-anal cross-veins before cubital fork, 
none connected; first anal vein connected to cubital fork 
three times; third anal with small apical fork; most of the 
cells in middle of wing are plainly longer than broad. 
In hind wings two cross-veins before radial sector, latter 
with six branches, first anal connected once to cubital fork 
and with eight or nine branches to the margin. 
The legs are moderately slender, more so than in the 
other small species of the genus, especially long is the tibia ; 
most of the bristles are black ; the spurs, unlike all the allied 
species, are short, hardly two-thirds as long as the basi- 
tarsus. 
Length of body 20 mm., length of fore wing 16 mm., width 
4 mm. One from Riverside, Calif., 25 September 1940, 
from Grace H. and John L. Sperry, to whom I am much 
indebted for many fine Neuroptera. Readily separated from 
others by the abbreviated tibial spurs. Type M.C.Z. no.
