Chrysopa darwini, sp. nov. 
Body pale yellowish, tip of abdomen darker ; palpi pale, 
unmarked, antennae from second joint out dark, but fading 
before middle, above each antenna is a large deep red spot 
in the depression, the basal joint of antennae also slightly 
reddish above; the pronotum shows faintly some reddish 
on each side-margin; veins and cross-veins green in both 
front and hind wings, stigma not conspicuous. The wings are 
moderately slender, not acute at tips, hairs on veins fairly 
long. In fore wings the gradates are parallel, the outer as 
near inner as to hind margin, the outer of seven, the inner 
of six veinlets, but the basal one is far before the others, the 
branches of radial sector only a little bent at inner gradates ; 
seven cubital cross-veins beyond the divisory, the latter 
ending only a little beyond the cross-vein above, the cell 
more than twice as long as broad, the base of cell only a little 
oblique and not plainly thickened, the second cubital cell is 
much shorter than the third ; the costal area hardly broader 
than the post-cubital area, latter only a little wider than the 
cubital area ; the costal stigmal area has no cross-veins, but 
two or three beyond. In the hind wings the triangular cell 
is fairly long and the free base of medius curved gently; 
there are four inner and five outer gradates, about parallel 
and the outer row about as near inner row as to outer 
margin. 
The pronotum is about as long in middle as broad behind, 
narrowed near front ; the hind tibiae are plainly swollen.
