allied to X ardates, quite distinct. On tlie upperside it is much 

 like iV. atratus (dry -season form) in colour and general appearance, 

 whilst H. ardates is a totally different shade, being dark violaceous 

 brown. On the underside, although the markings are placed as in 

 JV. ardates, they are always pure white. The female is dull 

 blackish brown on the upperside, with the disc of the fore wing 

 light shining blue and with an outer-marginal row of black spots 

 on the hind wing most conspicuous ; the underside is paler in 

 colour than the male, and the double marginal row of black 

 lunules is more distinct. Mr. Distant has probably figured and 

 described specimens of N. ardates as JV. alutu in his ' Ehopalocera 

 Malayana.' I hope the above remarks ■will enable the species to 

 be distinguished when met with. It is not an uncommon insect 

 in Borneo, but I have seen no specimens from any other locality. 

 Messrs. Godman and Salvin possess the type and other specimens, 

 whilst Dr. 8taudi]iger has also sent it. The type measures fully 

 1 inch, whilst the figure barely reaches 4 inch. 



Messrs. Distant and Pryer record N. aliita from Sandakan (Ann. 

 & Mag. ±\at. Hist. ser. 5, vol. xix. p. 267), but as Mr. Distant has 

 not recognized the species, probably not haA'ing seen the type, 

 without which it was of course quite impossible to do so, they 

 are probably referring to iV'. ardates \

The figure given of C. almora is misleading. I have examined 

 the type of L, ancyra in the FeJder collection and find that 

 C. almora, Druce, the type of which ( c? ) is in Messrs. Godman 

 and Salvin's collection, is identical with it. Mr. Doherty has also 

 described it as N. pseustis '.

1 Dr. Staudinger has kindly sent me for examination the type of his 

 Lycana ardeola from Palawan (Iris, ii. p. 97, 1889), which must be sunk as 

 a svnonym oi N. dana, de Nicev., with which it is identical. 



2 X. amaura, H. H. Druce (P.Z. S. 1891, p. 361. pi. xxsi. fig. 10), from the 

 Solomon Is., should be sunk as a synonym of N. ancyra, as also probably 

 should K gaura, Doherty, from Sumba (J. A. S. B. vol. Ix. p. 181. 1891), 

 which is stated (p. 182) to be something like 1/ycmna ■palmyra, Fe!d. T 

 cannot, however, see any resemblance. An error has been made in numbering 

 the figures on plate ii. in this part of the J. A. S. B. ; fig. 9 (pi. ii.) should read 

 fig. 11, and vice versa, as is evident from the desrriptions on pp. 182-184. 

 j\'. maniana, H. H. Druce (id. pi. xsxi. fig. 9), is also rerj' close and should 

 perhaps be considered a slight local race.
