turn black across front margin of the lobes, metanotum dark each side at 

 base of wings; legs with the tibiae partly dark, hind tibia dark on more 

 than basal half. Wings hyaline, veins mostly pale, the cross-veins mostly 

 dark, also the gradates, the base of subcosta and radius black, the latter, 

 however, pale for a short distance near base; origin of the radial sector, first 

 and second cubital cross-veins, and several veins behind are margined with 

 blackish, stigma dark at base. Pronotum short and broad, narrowed in 

 front. Wings rather broad, rounded at tips, divisory veinlet cuts off large 

 part of third cubital cell; nine outer and seven inner gradates in nearly 

 parallel series. 



Length of fore wings 14 mm. 



Chrysopa atrioris, sp. nov. 



Type.— M. C. Z. 10,861. Straits Settlements: Singapore (C. F. 

 Baker). 



Head below antennae mostly shining black, but with a transverse pale line 

 across base of clj^jeus; palpi black; first and second joints of the antennae 

 reddish brown, rest pale, vertex pale; pronotum pale, the sides dark, almost 

 black in front; legs pale, unmarked. Wings hyaline, veins pale, but some 

 cross-veins margined, very faintly brown, and several cross-veins near base 

 of wing partly dark. Pi'othorax as broad as long, slightly narrowed in front. 

 Wings slender, almost acute, costal area narrow; third cubital cell very long, 

 divisory vein ends much before its middle, about at the cross- vein; gradates 

 few, scattered, and irregular, about four in outer, three in inner series; hind 

 wings very slendei', acute, veins pale, four outer and two inner gradates. 



Length fore wing 9 mm. 



Chrysopa nigribasis, sp. nov. 



Ti^PE.— M. C. Z. 10,862. Straits Settlements: Island of Penang 

 (C. F. Baker). 



Pale, cheeks dark and three dark spots in a transverse row across face below 

 the antennae; mesonotum with dark band across connecting bases of fore 

 wings. Wings hyaline, veins mostly pale greenish, the costa of fore wings 

 for a short distance is black, and many of the costal cross-veins are black at 

 extreme tip. The pronotum is as broad as long, narrowed in front. The 

 wings are moderately broad, acute at tips, the costal area near base much 

 broader than in most species of the genus; six outer and five iimer gradates, 

 in fairly even series, rather far apart, but parallel; third cubital cell N\ith 

 strongly oblique tip, divisory veinlet ending near the end of the cell. 



Length of fore wing 11 mm.
