Oriental Lepidopterous Insects. 69

 denique obsoleto discoidali fusco cano adnata. (Exp. alar. unc. 2^.) 



The native place of this species, is, as far as I have ascertained, the 

 Island of Java, but it does 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 view^s, it stands in the series near the 

 confines of the genus Apatura. The antennae 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, 



PONTIA ThYRIA.

With the preceding concise character this species is noticed for the 

 first time in the Encyclopedic. 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 obliquity 

 to the vraig. 



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 hy several indistinct arcs.
