1945] Chrysopidae of Central America 153 
sanguined Navas has a line on antennae, but palpi pale, and a 
line behind the antennae. Other species with line on basal an- 
tennal joint have been seen, and are in the synoptic key. 
Chrysopa batesi sp. nov. 
Head pale; a broad red stripe on each side covering cheeks 
and extending inward and upward on inner side of eye, past the 
antenna, and broadly onto sides of vertex; palpi pale; antennae 
pale, basal joint with a rather broad outer reddish stripe; pro- 
notum much broader than long, sides parallel, two red spots 
half way from center to side margin; mesonotum with a red 
mark each side on anterior lobe, extending back along middle; 
abdomen with a row of red marks each side above. 
Fore wings with the gradates wholly dark; origin of radial 
sector, radials almost wholly, and some costals at lower ends 
dark; stigma pale yellowish. In hind wings the gradates slightly 
dark. In fore wings four or five inner and seven outer gradates, 
outer row parallel to margin, inner row plainly divergent; six 
cubitals beyond the divisory cell, latter ends much beyond the 
cross-vein; third cubital cell as long as second, broader. In the 
subcostal stigmal area two or three cross-veins ; hairs on veins 
rather short; branches of radial sector slightly bent at inner 
gradates; costal area at broadest is equal to the radial and also 
to postcubital area, latter about a third broader than cubital. 
In hind wings four inner and five outer gradates, not quite 
parallel, and the inner series nearer to the radial sector. 
Length fore wing 12 mm., width 4.5 mm.

Type M.C.Z. no. 25646. 
Agrees partly with bouvieri and diver gens ; but neither have 
stripe on basal joint of antenna, and neither have extensive red 
marks on head. 
Chrysopa brevihirta sp. nov. 
Head pale, a faint reddish mark between antennae and also a 
faint reddish suffusion on the vertex just back of each antenna, 
no mark on cheeks; palpi and antennae pale yellowish, un- 
marked; pronotum pale, with a red stripe each side, rest of 
thorax, abdomen, and legs pale, unmarked. Fore wings with 
the gradates brown, radials and costals, and a few other cross-
