114 Mr. Butler's notes on the species of 



19. Euchromia formosana, n. s. (PI. IV., fig. 7). 

 Pattern of primaries nearly as in E. Tiorsfieldii ; the orange 

 patches wider ; the interne -median patch partly divided before the 

 middle by two black dots placed obliquely ; secondaries nearly as 

 n E. polymena, but the basal patch smaller ; body as in E. orien- 

 tails, the fourth to sixth segments being carmine-red. Expanse of 

 wings, 48 mm. 



Formosa (Hobson). 



20. Euchromia fraterna, Butler. 



A species occurring in Moulmein, of which, at present, 

 we have only one example, but which (judging by the 

 constancy of its allies) is almost certain to be a fixed 

 type ; Herr Kober, however, says that he agrees with 

 Herr Snellen in regarding this and E. celebensis as 

 " insignificant aberrations, unworthy of names;" after 

 which he proceeds at once to give one of them a new 

 name himself. 



21. Euchromia orientalis, Butler. .(PL IV., fig. 6). 



The common Burmese representative of E. polymena : 

 the type unfortunately was labelled " N. India" doubt- 

 less an error, as the species has since come in some 

 numbers from Burmah ; though, unhappily, many of 

 them were so much injured as to be unfit to put into the 

 collection. 



22. Euchromia polymena, Linneus. 

 We have eight examples, from India and Ceylon. 



23. Euchromia celebensis, Butler. 



Four specimens from the Celebes : this is the Glau- 

 copis butleri of Kober ; he says that it differs from 

 E. celebensis, in having the " lower radial of the prima- 

 ries broadly bordered with black" a slightly variable 

 but constant character of E. celebensis. 



24. Euchromia lama, Butler. (PL IV., fig. 8). 



Although we only have one example of this species, 

 and with the vague locality "E. India," it is so well- 

 marked that its distinctness can be considered certain.
