NOTES ON BUTTERFLIES OF ADEN. 211 



may be parallel to that of some species of Megisba and Nacaduba^ 

 genera having both tailed and tailless forms. 



14. ^2;a?iwa amara/t,Lefebvre,Voy. Abyss., vol. vi, p. 384, pi, xi, 

 figs. 5, 6 (1847). Common everywhere, 



15. Azanus zena, Moore, P, Z. S., 1865, p. 505, pi. xxxi, 

 fig. 9. Common everywhere. 



16. Azanus sigillata, Butler, Ann. and Mag. Nat. Hist., 4th 

 series, vol. xviii, p. 483 (1876). Generally distributed throughout 

 the neighbourhood, but nowhere common, Mr. de Niccville, Butt. 

 Ind., vol. iii, p. 125, unites this species with A. gamra (a species I 

 have never met with) ; he puts A. crameri, a Ceylon species, also as a 

 synonym of that butterfly. There is certainly a strong resemblance 

 between A. sigillata and A. crameri. 



A. zena and sigillata difi'er widely in their habits, the former 

 being a sturdy little fellow who sits at the end of a babul twig and 

 flies about in a sharp decided manner, generally returning to his 

 original perch. A sigillata, on the other hand, is one of the weak- 

 kneed vacillating folk, and goes flopping along over low herbage 

 in a purposeless manner; in this, too, it is resembled by A. crameri. 



17. Turucus piilcJter, Murray, Trans. Ent. Soc. Lond., 1874, p, 524, 

 pi. X, figs. 7, 8. Common throughout the neighbourhood. 

 Mr. de Niceville, Butt. Ind., vol. iii, p. 194, unites this species with 

 T. plinius, judging from the specimen of the latter from Continental 

 India only, I was loth to accept this synonomy, but the specimens 

 I have taken in this neighbourhood (Trincomali) have almost 

 converted me. 



18. Turucus theoplirastus, Fabricius, Ent. Syst., vol. iii, pt. 1, 

 p. 281, n. 32 (1793). Common everywhere. 



19. CJiilades trocliilus, Freyer, Neuere Beitr., vol. v, pi. 440, fig. 1 

 (]844). Grenerally distributed. Mr, de Niceville, Butt. Ind., vo\. iii, 

 p. 91, unites this species with CiJutU. I do not think thatniany 

 Field Entomologists who have met with both species in life will agree 

 with him in this. My own reasons for dissenting are as follows: — 



I have met with the two species : — 



Aden C. trochilns. 



Campbollpore C. trocJiilus and C. iJidli. 



Trincomali C. putli.
