the white spots and the broken portion of the yellow band. The 

 inner margin of the tail has three elongated white spots upon it. 

 The under surface of the posterior wings differs from the upper 

 in having the yellow band continuous, the band of spots all white 

 and larger in size, and being devoid of the blue patch of colour. 

 A ? variety occurs where the posterior wings want on both sur- 

 faces the apical band ; and the posterior wings have the yellow 

 band reduced to a triangular patch on the anterior margin on both 

 surfaces, and the band of spots is not so decided on the upper 

 side, but the blue patch is spread over more of the disc of the 

 wing. See PI. X. fig. 6.

Inhabits New Grenada. 



In the Collection of Mr. Hewitson. 



A very distinct and beautiful species, apparently given to vari- 

 ations, and quite unlike any yet discovered. 



Erycina Calphurnia, W. W. Saunders. $ . (PI. X. fig. 8.) 



In my former paper on the Eryclnidce, in the " Transactions of 

 the Entomological Society," I described the female of this species, 

 that sex being only then known. Since the publication of -that 

 paper, Mr. Bates has sent from the Amazon region the male, 

 which differs from the female in the following respects. In having 

 the transverse white bands of the wings narrower, the one on the 

 posterior wings not arising so immediately under the termination 

 of the band of the anterior wing, and terminating on the disc of 

 the wing before the wing is half traversed ; in having a red 

 streak of colour extending along the internal margin of the pos- 

 terior wing from the base to the tail ; in having the tails some- 

 what longer and glossed above with a delicate pale greyish-blue 

 colour, and on the underside in having a little more of the red 

 colour at the base of the tails. 



Expansion of wings I| inch. 



The nature of the long tail-like appendages to the posterior 

 wings, alike in both sexes and general style of colouring, makes 

 me place this species in a section by itself, to which I give the 

 name of Euerycina, and probably, w hen the transformation of the 

 species are known, this section will form a good sub-genus.

The head and antennae are black. The anterior wings are 

 above black, with a transverse rather broad crimson curved band
