througli the centre of which a series of white spots can be dimly seen. 

 Expanse of wings 80 mm. 



Larat. 



This is one of the most beautiful species in the geniTS ; it bears a vague 

 resemblance to //. albula of Timor, which, however, belongs to the 

 H. anomala grouis. 



5. Precis expansa, Butler. 



o . Allied to P. timorensis of Wallace, from which, however, it differs 

 io its clearer fulvous colouring above, the blackish colouring of the external 

 area being confined to the apex, the paler coloration of the iinder surface, 

 its broader and less produced primaries, and the less pronpunced caudal 

 angle to the secondaries. Wings above tawny, with black markings and 

 bluish-centred ocelli, as in P. erii/one of Java (Cramer, Pap. Exot. i. pi. 

 62. E, E), but the white markings of that species replaced by a slightly 

 paler tint of tawny than the ground colour ; under surface as in P. erigone. 

 Expanse of wings 52-54 mm. 



liarat. 



Why the P. erigone group has been referred to Junonia and the 

 scarcely differing P. natalica to Precis it would, I think, be hard to 

 explain. P. antigone and P. natalica seem very closely allied species.

Lyccena patala, Kollar, Hiigel's Kaschmir, iv. 2, p. 419 (1848). 

 $ . Muru Island. 



Does not differ from Indian specimens excepting in the slightly whiter 

 tint of the under surface. 



7. LaMPIDES aiLIANUS. 



Kebpcria cdianus, Fabricius, Ent. Syst. iii. I, p. 280. n. 79 (1793) 

 Larat. 



Does not differ from Indian specimens excepting in its slightly inferior 

 expanse of wings ; in colouring and pattern it perfectly agrees.

Larat. 



Most nearly allied to D. vislinu of Moore from Java (with which species 

 it v>-as associated by Wallace). It differs in its superior size, the 

 narrower black area of the upper surface, the deeply sinuated inner edge 

 of the black area on the primaries, the apical series of spots muoli 

 smaller, the fifth, as Boisduval says, " tres petite et ponctiforme," whereas 

 in P. vishnu this is the case with a sixth spot not present in P. timorensis : 

 primaries below with the basal pale area cuneiform (not angular), pure 

 lemon-yellow within and just below the cell, otherwise pearl-white ("la 

 base gris-blanohatre saupoudree de jaune pur," Boisd.): secondaries with 

 only the basi-abdominal third* brilliant golden yellow; suffused at 



* The carelessness of Boisdnval's desoription at tliis point prdbably misled 

 Wallace ; he says : — " La inoilie' ante'rleure d'un beau jaune de chrome." On 

 the other hand, the yellow of D. cislmu has a decidedly dull creamy appear-
