1884.] RHOPALOCERA FROM DOMINICA. 315 



One species of Nymphalinae is apparently new, and belongs to the 

 Antillean section of the genus Ancea, of which there is a species in 

 Cuba and another in San Domingo. 



Pieris Virginia alone of the Pierinse has any claims to peculiarity : 

 it has been several times noticed in the Antilles, but the islands not 

 specified, with the exception of Cuba, where we rather doubt its 

 existence. 



I^tpilio neodamas is in the same category as Pieris Virginia, and is 

 probably only found in the Windward Islands. 



Of the Hesperidse it is difficult to speak with certainty. Two 

 species, both described in this paper, have probably the same range 

 as the Papilio and Pieris. 



In conclusion, we may say that we still look for considerable 

 additions to the present list ; and these may fairly be expected to 

 include peculiar species of Nymphalidte and Hesperidse, and perhaps 

 of Papilioiiidse. The widely ranging forms, such as frequent the 

 more open country, are probably most of them included in the fol- 

 lowing list. It is in the forests and in the older vegetation that 

 novelties must be sought. 



1. Danais plexippus.

 i. p. 1. 



This Danais appears to be common in Dominica, as there are 

 many specimens in Mr. Angas's collection. These all belong to the 

 form prevalent in the northern parts of South xlmerica, in which the 

 spots in the apical portion of the primaries are purer white than in 

 North- American examples. 



2. COL^NIS CILLENE. 



Pa lilio cillene. Cram. Pap. Ex. t. 215 f. D, E. 



We have already stated (Biol. Centr.-Ani., Rhop. i. p. 168) that 

 the Cuban species of this Colcenis conforms best to Cramer's figure, 

 though his specimen is stated to come from Surinam ! The examples 

 in the present collection differ from the typical form of C. cillene in 

 that the transverse band of the primaries beyond the cell is rather 

 more strongly developed. 



This is apparently a common species in the island.- 



3. Agraulis vanilla. 



Papilio vanillce, Linn. Syst. Nat. i. p. 787. 



Jgraulis vanillce, Godm. & Salv. Biol. Centr.-Am., Rhop. i. 

 p. 171. 



A very widely ranging species, found throughout the whole of 

 tropical America, as well as in the West-Iudiau Islands.
