I have little doubt that this identification is correct, although the 

 description is not convincing and the broad yellowish costa as given 

 in the figure is less broad in my specimen. I take it that Sir George's 

 figure is that of a female. I have other specimens from New Guinea, 

 identified by me at the B. M., and which agree entirely with the Ceram 

 specimen. The underside of the abdomen of all my specimens is, 

 however, pale turquoise-green (vii), and not silvery as stated in the 

 description.

47. Margaronia (Sisyrophora) joiceyi sp. nov. 



This species is very close to M. pfei ferae Led , but is easily 

 distinguished from it by the much broader suffusion along the outer 

 margins of both wings on upper and under side. 



$ . Both wings, thorax and abdomen on under and upper side 

 and legs white ; wings thinly scaled, but more densely than in pfeijjferae ; 

 tegulae and patagia and scales between antennae clay colour (xxix), 

 suffused with fuscous (xlvi) ; palpi white, with inner half from base 

 to tip fuscous ; antennae white, basal portion and terminal part 

 suffused with fuscous, basal joint and tooth clay colour, a tuft of glossy 

 fuscous scales on inner side before the tooth ; abdomen above with 

 avellaneous (xl) rings anteriorly on most segments and reaching half-way 

 of segment, last segment almost entirely avellaneous and irrorated with
