The following species of Butterflies are cbie% from the collec-

 description. 



Genus Pieris, Boisduval. 



Pieris figulina, n. sp. PI. VIII. fig. 1.

 maculam quadripartitam rufam includente, lunula apud angulum 

 analem et plerumque venis fuscis ; areola basali, costa anticaruiu 

 ct margino interne posticarum grisesccntibus ; costa posticarum 

 flavesceute : corpus nigro-fuscum abdomine pallidiore, pilis viri-

Hab. Singapore, (^, Coll. Roberts. Borneo, $, Coll. Hewit- 

 son. 



This beautiful and very distinct species is evidently allied to 

 the blue Celestina of Boisduval : it may belong to the Nelo 

 group; but the front wings differ considerably in form. I have 

 recently seen a specimen of the female from I3orneo. 



Genus Terinqs, Doubleday. 



Terinos Rohertsia, n. sp. PI. VIII. figs. 2, 3, 4. 



Abe forma et magnitudine Terpandri (Hewits.).
