Notes on Synonymy. 



The following notes on synonymy have been compiled from 

 personal inspection of the types. I am also indebted to Kirby's 

 Catalogue of the Heterocera for several. 



RHOPALOCERA. 



Ialmenus Dameli, Semp. 



Mus. Godf. Lep. xiv. 166, 1878. 



I believe this species to be identical with the insect described 

 by Dr. T. P. Lucas (Proc. Roy. Soc. Queensland, vi. 156, figs. 

 1-2, 1889) under the name of Ialmenus Illidgei, which Miskin 

 considers to be a geographical form of ictinus, Hew., a decision 

 however with which I disagree. 



^o"- 



Hesperilla dirphia, Hew. 



Descr. Hesp. p. 38, n. 2, 1868; Exot. Butt. v. Hesp. and Cyclop, 

 f. 1-3, 1874: ^. Hesperilla trimaculata, Tepper, Trans. Roy. Soc. 

 S.A. iv. p. 32, t. 2, f. 4, 1881 : J. IlesjjerUla quadrimaculata, 

 Tepper, I.e. t. 2, f. 2, 1881. 



It will be seen that the male and female were described under 

 d liferent names.
