A NEW SPECIES OF CHRYSOPA 
By Nathan Banks 
New species of this genus are so uncommon in our 
country today that the finding of one of the most distinct 
forms hitherto known merits a separate article. 
Chrysopa eureka sp. nov. 
A heavy-bodied Chrysopa like rohusta , but mostly dark 
and of quite different markings and venation. 
Head pale yellowish, unspotted; palpi black; antennae 
black, basal joint pale. Thorax dark grey, heavily marked 
with black, underside and pleura mostly black. Pronotum 
with eight black spots arranged in two transverse rows, 
black spots on lateral lobes of the meso — -and metanotum. 
Legs dull yellowish, a black band before tip of each femur, 
and the tarsi somewhat darkened. Wings with mostly 
black cross-veins, gradates, and apical forks, the longi- 
tudinal veins with streaks of black; stigma greyish, with 
several cross-veins behind margined with dark. 
Face broad ; antennae rather short and stout ; pronotum 
very broad, but little narrowed in front; rest of thorax 
very broad; abdomen stout and short; legs stout, much 
more so than in the common species, the front and mid 
tarsi more than one-half the length of the tibiae. 
Wings moderately broad; venation not dense, about 
17 costals, eight connecting veins from the radial sector 
to radius, seven cubital cross-veins beyond third cell, di- 
visory veinlet ends much beyond the cross-vein, divisory 
cell of moderate size, about five gradates in each series, 
the two rows not very near together and the outer one 
hardly nearer to the margin than to the other row. Length 
fore-wing 17mm, breadth 5.5mm.
