(Plate XVII.) 



Genus Idmais, Boisd. (1836). 



Idmais tripuncta, sp. nov. (PI. XVII. fig. 9.) 



Affinis Idmaidi fulviae (Wallace, Monog. Piei'id.), alls autem anticis 

 supra, area apicali, maculas tres solum includente, posticisque ma- 

 culis marginalibus majoribus subquadratis : subtus /undo vivide 

 flavescente, margine interna posticarum ciliisque anticarum Icetis- 

 simefulvescentibus ; maculis transerrantibuspostmediisfulvisfusco 

 roratis : stigmate anticarum nigro majore. 

 Exp. alar. unc. 2. 

 Hab. India {Coll. Roberts). 



This species is nearly allied to I.fulvice, Wallace (Ent. Soc. Trans. 

 3rd ser. vol. iv. pt. 3. p. 392. n. 5, pi. 9. fig. 5), of which it is pro- 

 bably a local form. The exact locality of/, tripuncta has not been 

 clearly ascertained. 



Genus Acr^a, Fabricius. 

 Section Planema, Doubleday (1848). 

 Planema macarina, sp. nov. (Pl. XVII. fig. 6.) 



S . Affinis P. macariae (Fabricius), area autem discoidea anticarum 

 fusca, et fascia transversali ferruginosa pone cellanu alarum mar- 

 gini subparullela : punctis basalibus posticarum paucis, aliquando 

 coeuntibus. 

 Exp. alar. unc. 2^^-2-|-^.

AUied to P. macaria, but smaller ; the cell of the fore wings black- 

 ish brown, the transverse band slanting inwards instead of outwards, 

 and the black spots on its inner edge also following in the same di- 

 rection ; the basal spots of the hind wings smaller, and on the under- 

 side occasionally running together. 



Genus Cirrochroa, Doubleday (1848).

 pra haud nigro, punctisque nonnullis pone cellcB anticarum finem
