228 Mr. P. I. Lathy's Monograph of the Genus Calisto. 



Men^tries' description * is evidently of this species, 

 although he refers it to C. hysms, Godt. — his name 

 " lysius" being merely one of the several similar ortho- 

 graphical errors throughout the paper. 



After having examined a long series of each species, I 

 find that the separating characters given in the key are 

 constant. Besides these differences, C. confusa differs 

 from C. hysius in the following points : the much larger 

 ocellus of the hind-wing; the white borders of the discal 

 lines ; the lilac area above ocellus, and the deeper red in 

 cell of fore-wing. 



In conclusion, I wish to express my thanks to Dr. 

 Staudinger, who generously sent me his specimens of this 

 genus for examination, and to the Hon. Walter Rothschild, 

 Mr. Godman and Mr. H. Grose-Smith, who kindly allowed 

 me to visit their collections.
