Mnemosijne pnncfipcnnisj Dist. 



One female specimen from Bang Bo, Tndo-Cliina (7^ V. de 

 Salvaza, 25. iv. 1915), which agrees with the type-specimen. 



Borijsthenes mlanjetisis^ sp. n. 



Female. — Length 3, tegmen 5 mm. 



Sc-\-R forming a short stalk, M arising from basal cell at 

 the same spot as Sc-\-R and forking about level with the 

 apex of clavus, wdth five apical celis^ Mi, lai 2 ; s? 4* CI aval 

 vein joining commissure before apex ; tegmina but slightly 

 tectiforni when at rest, overlapping beyond apex of clavus. 



Ovipositor complete, longer than pygofer, udiich is small 

 and longer than broad with a longitudinal depression. Anal 

 segment very small. 



Light yellow; eyes dark brown, apex of labium dark, 

 ovipositor brown. Tegmina hyaline, slightly opaque with 

 waxy secretion, veins yellow except where the dark spots are, 

 a dark mark at base of 31, one at fork of Cu, a light one in 

 middle, another at stigma, and another larger one near apex 

 of costal cell extending into subcostal ; a small spot slightly 

 distad. of Sc + R fork, a small round spot between R and M 

 at apex ; the cross-veins between the fork of il/i, Jij ^i^d the 

 fork of JYg, J/4 and over cross-vein between M and Cw, fuscous. 

 Wings hyaline, opaque with waxy secretion, a black spot 

 between R and M near middle, apical cells fuscous, veins 

 yellow, slightly fuscous. 



Described from four females from Mt. Mlanje, Nyassaland 

 (S. A. Neaue, 5. i. 1914). This appears to be the first species 

 of this genus to be reported from Africa. 



Derbidae. 



Zoraidafidgans, sp. n. 



Male. — Length 7, tegmen 16, wings 5 mm. 



The basal median sector joined to the cubitus, making 

 the latter four-branched; wing about one-third the length 

 of the tegmen. Antennie cylindrical, slightly longer than 

 face. 



Lateral margins of pygofer broadly angular, medio-ventral 

 process conical in outline. Anal segment slightly U)nger 

 than broad, apex with a slight emargination in mi(hlie, 

 making it bilobed. Genital styles about as long as anal
