costal crossveins connected with each other transversely by small 

 veinlets at level of then* forks. Radius with four branches, apical 

 branch forking twice before outer gradate ; media forking at about the 

 level of origin of first branch of radius; M3+4 coalescing with Cui for 

 a short distance; three series of gradate crossveins, 4 crossveins to 

 inner, 5 to middle, and 10 to outer gradate series. 



Figure 2. — Nusalala kriigeri, new species (male genitalia) : a, apex of abodmen, lateral 

 view; b, anal plate, lateral view; c, 10th sternlte, lateral and slightly dorsal view; d, para- 

 meres, lateral view. 



Hindwing 8 mm. in length; membrane hyaline, narrowly tinged with 

 fulvous in costal area, and narrowly grayish along outer and hindmar- 

 gins; outer gradates almost black; inner gradates and adjacent portions 

 of longitudinal veins fuscous; first branch of Cui most conspicuously 

 fuscous. Five branches to radial sector, six crossveins to inner, and 

 nine to outer gradate series. 



Male genitalia: Anal plate subtriangular in lateral view with 

 ventrodistal angle produced into an acute spinous projection; pro- 

 jection arising from apodeme along the lower margins of anal plate and 

 ninth tergite and extending basally into eighth segment. Ninth 

 sternite, forming subgenital plate below anal plate, with rounded 

 distal margin. Tenth sternite with large, oblong lateral "wings," 

 each produced into a short roundish lobe at ventrodistal angle; mid- 

 dorsal part of bridge between "wings" raised into a prominence, and 

 from below this dorsal prominence arises single long, tapering aedeagus 

 with an acute apex; three pointed processes of about equal length on
