Erffolis ariadne is probably the E, coryta of Wallace's paper, and 

 Pamphila sunicis his P. mcesa ; therefore I have not included these. 

 The number of species of Butterflies now known from Formosa is 80,

Euchromia fraterna, Butler, Journ, Linn, Soc. vol. xii. p, 364

One example of this beautiful species, I find, by comparing it 

 with other specimens, that my original description omitted one 

 important character — the first black belt on the primaries, which is 

 broad and continuous in E. polymena and E. orientalis, being here 

 represented by two black conical dots below the median vein. The 

 sixth segment of the abdomen is often wholly scarlet, as in E. ori- 

 entalis, such being the case in the Formosan example before mc.
