Notes on species described by Mr. F. Walker in the Trans. Tint. 

 Soc, Lond., vol. v. (new series), part 5, p. 182-186. 



Genus Varnia, "Walker = Ithone, Newman. V. perloides is an 

 interesting second species of this curious genus. 



Osmylus punctipennis, Walker, may be retained in the genus for 

 the present, but is aberrant ; area costali seriebus 5 — 2 areolarum. 



Ghrysopa ignobilis, Walker — a true Chrysopa. 



C. pubicosta,~Wdi\kev, belongs to Osmylus as a slightly aberrant form. 



O. mozambica, Walker = Nothochrysa variegata, Burin., with which 

 N. rufostignia, McLach. (Journ. Linn. Soc. Zool. vol. ix, p. 253), is also 

 identical. The native country of the allied N. cequalis, Walker, is India 

 and Malacca. 



Apochrysa beata, Walker, is allied to A. marionella, Guerin, but is 

 smaller, and without the dark cloud in the fore-wings.
