658 Dr. G. B. Longstaff's Bionomic Notes on Butterfiies. 



In this species, which has a habit of curvetting rapidly 

 about before settling on the ground, the lobes, which are 

 small, are everted. The hind-wings are folded in such a 

 way as to make a very slight convexity between the two 

 tails, the nervures corresponding to the latter lying in 

 re-entrant angles. 



Ba-jpalcL lazulina, Moore. Ceylon, 1908. The lobes are 

 everted. 



Loxurct arcuata, Moore. Ceylon, 1908. This species has 

 a peculiar darting flight. The arrangement of the wings 

 at rest is somewhat complicated : the lobes, which are 

 small, are ^, or perhaps f, everted, showing an eye-spot 

 when the insect is looked down upon from above ; the long 

 tails appear to be somewhat twisted — one overlying the 

 other, their black and white tips curved upwards. The

portion of the hind-wing between the extremity of the 

 abdomen and the lobe is bent inwards. As touching the 

 very nearly allied Indian species, L. atymnus, Cram., 

 I noted at Calcutta in 1908, "its wings are much plaited 

 longitudinally, and when at rest its extremely long tails, 

 crumpled look, and brown colour give it quite the appear- 

 ance of a dead leaf." * 



Neither the inverted attitude nor the everted lobe would 

 appear to be confined to the Lycxnidx, as the following 

 examples prove. 



The common Jamaican Satyrine, Calisto zangis, Fabr., 

 has a peculiarity of construction which appears significant. 

 The anal angle of the hind-wing is somewhat produced, 

 moreover on either under surface, at the angle, there is a 

 small ocellus. When at rest the wings are raised over the 

 back in the usual manner ; the abdomen is covered by the
