Genus Vaenia, Walker = Ithoke, Newman. V. perloides 
interesting second species of this curious genus. 
Osmylus punctipennis, Walker, may be retained in the genus i' 
the present, but is aberrant; area costali serielus 5 — 2 areolarum. 
Chrysopa ignohilis, Walker — a true Chrysopa. 
C. puhicosta,Wa\keY, belongs to Osmylus as a slightly aberrant forri 
G. mozambica, Walker = Nothochrysa variegata, Burm., with whi<i 
N. rufostigma, McLach. (Journ. Linn, Soc. Zool. vol. ix, p. 253), is al 
identical. The native country of the allied N. oequalis, Walker, is Ind« 
and Malacca.
