Watson (P. Z. S. 1893, p. 118) puts this species as a synonym of tessellata. Hew., 

 and as it resembles that species in all but the colour of the pale spots on the underside, 

 we were, so long as we had seen female specimens only, inclined to adopt the same 

 view, seeing that the type was a female ; but having, through the kindness of Herr 

 Semper, had the opportunity of examining one of his two males from E. jNIindanao, 

 which exactly agrees with the original description and figure as well as with female 

 specimens in coll. Elwes, we are satisfied that it is a distinct species. It has been sent 

 to us from Java by Staudinger as tessellata. Hew. 



Plastingia tiburnia. 



Plastingia viburnia, Staudinger, in. litt. ; Semper, Schmett. Philipp. p. 314 (1892). 



Of this very distinct species the female resembles the male, save that the pale 

 markings on the upperside are yellowish white instead of deep yellow.

Mr. de Niceville identifies /. indrasana, which he described in the joint paper on 

 Tavoy butterflies, cited above, as I. corissa. As the type is now in the Calcutta Museum, 

 we take his word for it, but the plate does not represent our specimens correctly. A 

 female of P. /«to)/ff, Stgr., marked by Dr. Staudinger as "typisch," differs from the same
