3 LLOYD'S NATURAL HISTORY. 



expanse, and has short obtuse tails, longer in the female than 

 in the male, appears to be common throughout the northern 

 part of South America, and it extends as far north as British 

 Honduras. The wings are dark brown or blackish, and in the 

 male the greater part is filled up with rich blue, bounding 

 which, on the fore-wings, is a more or less distinct whitish 

 line. Towards the extremity of the inner-margin of the hind- 

 wings, and across the base of the tail are some red bands. 

 The female is similar, but instead of the blue colour of the 

 male, it has two transverse white bands, that nearest the base 

 being the broadest. 



GENUS ANCYLURIS. 



AncyluriSj Hiibner, Verz. bek. Schmett. p. 23 (1816); Schatz 



and Rober, Exot. Schmett. ii. p. 239 (1885). 

 Erycina, Fabricius, in Illiger, Mag. Insekt. vi. p. 266 (1807);

Diurn. Lepid. p. 428 (1851); Godman and Salvin, Biol.

The name Erycina, having been used by Lamarck for a 

 genus of shells in 1805, cannot be retained in Lepidoptera. 



As mentioned under the heading of the genus Diorhina^ 

 Ancyluris differs by comparatively slight characters. The 

 wings are black above, banded with red, orange, or, more 

 rarely, white, and are sometimes adorned with blue markings ; 

 while the under surface is usually richly banded and suffused 

 with various metallic tints of blue and green. The species 

 measure somewhat less than two inches in expanse, and the 

 hind-wings are produced into a lobe or tail, turned outwards, 

 and usually much longer in the female than in the male. The 

 species are most numerous in the northern parts of South 

 America.
