34 LLOYD S NATURAL HISTORY. 



middle of the hind-wings. Thence the band turns outwards, 

 becoming Hght blue, and coalesces with a narrow light blue bor- 

 der which runs down from the middle of the hind-margin of the 

 fore-wings, and borders the lower part of the hind-wings, which 

 is gradually produced into a long, but not very pointed tail, 

 which is likewise blue, except at the tip, where it is white. 

 Within this blue stripe and the brown inner margin is a choco- 

 late-coloured stripe, running up to the base of the hind-wings. 

 In the female the white band is broader and longer, and is 

 separated on its lower end by a red line from a white line which 

 runs from the base of the hind-wings to the inner edge of the 

 tail ; the latter, as well as the hind-margin of the hind-wings, 

 being bordered by a white line. The under side of this hand- 

 some Butterfly is bluish-white at the base, separated by a dusky 

 band from a whiter space, the outer part of the wings being 

 tawny, except for the narrow white edging of the hind-wings. 



The present classification of the LemoniincB is very unsatis- 

 factory, and the sub-sections are certainly only tentative and 

 provisional. This may be seen from the dissimilarity of the 

 various genera which are included with Ruerycina in this group. 

 One of these is Barbicornis, Latreille, which differs from 

 Euerycina nearly as much as Syrmatia differs from Aftcyluris. 

 Barbicorjiis basalts, Godart, is a Brazilian Butterfly with such 

 slender antennae that some authors have regarded it as a Moth. 

 It expands about an inch and a half; the fore-wings extend far 

 beyond the hind-wings, and are adorned with two fulvous or 

 orange bands, one running from the base along the lower part 

 of the cell, and then running outwards, nearly parallel to the 

 inner-margin ; and the other oblique, and sub-apical. The 

 hind-wings throw out a straight narrow tail, as long as the hind- 

 wings themselves, from the middle of the hind-margin. Several 

 genera of this sub-section, like some of those of the last, are 

 black, with sub-hyaline stripes ; but the largest and most impor-
