oblongis; serie insuper interiore punctorum minutorum, arcu 
denique obsoleto discoidali fusco cano adnato. (Exp. alar. unc. 25.) 
The native place of this species, is, as far as I have ascertained, the 
Island of Java, but itdoes not form part of my own collection, The 
peculiarities of our insect, as far as regards habit and outline, are indicated 
by the name: according to my views, it stands in the series near the 
confines of the genus Apatura, The antenne agree in form with 
Aconthea, but they are slightly abbreviated. The external character is 
likewise intermediate; the colouring imitates that of Apatura Lasinassa, 
while the abbreviated transverse bands are more peculiarly a charac- 
teristic of the individuals of Aconthea. I have endeavoured, in the 
description, to represent every essential particular of its markings.

With the preceding concise character this species is noticed for the 
first time in the Encyclopédie. Its native place is the Island of Java. 
Three specimens have come under my observation; two of these, a male 
and a female, form part of the Museum at the India House; a third was 
presented to my private collection, by Mr. G. B. Sowerby. In the 
prosecution of my Descriptive Catalogue it will be disposed in a separate 
section, with several other Javanese and Asiatic species. The anterior 
‘wings in the individuals of this section are elongate-triangular, somewhat 
acuminate, with an uniform posterior margin, giving a decided aie 
to the wing. 
The male, in our insect, is distinguished by a more rich and saturated 
colour above, by very prominent blackish nervures, and by a very faint 
posterior border. In the female, both wings have a distinct broad black- 
ish posterior border, and the anterior pair has besides a band of the same 
colour near the outer apical angle, passing obliquely from the middle of 
the costa towards the margin, being succeeded by several indistinct ares.
