440 MR. H. H. DRUCE ON [May 17, 



Nacaduba NEBUiiOSA, sp. n. (Plate XXVII. figs. 10, 11.) 



Allied to N. keiria, mihi, but without the tails. 



S . Upperside : colour the same ; hind wing without the black 

 spots at the anal angle. Underside greyish creamy white, with 

 markings and spots arranged as in N. keiria, but very faint and 

 indistinct. 



$ . Upperside as N. keiria, $ ; underside as male. Head, thorax, 

 and abdomen concolorous with wings. Antennae and legs brown, 

 spotted with white. 



Expanse as N. keiria. 



Espiritu Santo I., MallicoUo I., New Hebrides {Woodford). New 

 Hebrides (Mathew) (Mus. G. Sf S.). 



A form distinct from anything I have seen. 



Nacaduba biocellata. 



Lyccena biocellata, Fe\d. Reise, Nov., Lep.ii. p. 280. n. 352, t. 35. 

 f. 14 (1865). 



Lampides armillata, Butl. P. Z. S. 1875, p. 614. n. 22. 



New Hebrides {Mathew). 



I have before me a male and two females of this pretty little species, 

 which agree exactly with two in the Hewitson collection from Swan 

 River ; also with Felder's figure. 



Mr. Butler, in describing his species, evidently overlooked Felder's 

 insect, at least he makes no mention of it. 



The male is much like the female, but has the violaceous extending 

 almost to the margins of both wings. 



I am unable to state positively whether this species should be 

 placed in Nacaduba or in Prosotas, as I have no specimen for dissec- 

 tion. 



Nacaduba deplorans. 



Lampides deplorans, Butl. P. Z. S, 1875, p. 614. n. 23. 



Mare I., Loyalty Is. {B. M.). 



The type in the British Museum is the only example I have 

 seen. It certainly is not the female of N. biocellata, as both sexes of 

 that insect are in Messrs. Godman and Salvin's collection. 



Nacaduba? catochloris. 



Lyccenal catochloris, Boisd. Voy. Astr., Lep. p. 78 (1832) ; Butl. 

 P. Z. S. 1874, p. 286. 



Taiti, Society Is. {Boisd.). 



I have not been able to identify this species. Mr. Butler in 1874 

 suspected it to be a Banis, but as that genus is not known to occur 

 amongst these islands I think it will probably turn out to be a 

 Nacaduba. 



Thysonotis, Hiibn. 



One species only of this genus has been discovered in these islands, 

 examples of which are contained in the British Museum and also in 

 our own collection.
