I have liere figured two Malaccau specimens contained iu the Britisli Museum, and 

 identified as belonging to Felder's species by Mr. Butler. The following is the original 

 diagnosis : — 



" 3' • Alio supra pluinbeo-violaceffi, striga anteciliari nigro-fusca, subtus pallidc cano-bruimcaa, fasciis 

 binis macularibus fuscis, albo ciuctis, connatis ante margiuem, anticarum fascia subbasali, costam 

 pertingente, macula subcostal!, fasciola discocellulari fasciaque exteriore, catenulari apud ramum medianum 

 secundum fracta, posticarum fascia basali, fasciola discocellulari fasciaque exteriore apud ramum 

 medianum secundum contigua, auticc bis fortiter— et postice fracta, catenulari fundi coloris, lateraliter fusco 

 cinctis alboque marginatis, posticffi macula postica orbicular!, circulo lutescente intus amplexa, extus arcu 

 teuui metallico divisa maculisque binis aualibus minutis, metallico lutescentique intus limbulatis atris." 



Exp. wings, <y and 2 , 27 to 28 millim. 



Hab. — Malay Peninsula; Malacca (Pinwill — Brit. Mus.). — Philippine Islands; Luzon (coll. Feld.). 



This species seems to be very closely allied to X. atrata,* Horsf. (nee. Cram.), and so 

 again with the equally similar form described as N. lyromiuciis, Moore, f Horsfield's species, 

 however, appears to be distinct by the colour pattern of the wings of the female " transmitting 

 a white patch on the disk." 



3. Nacaduba viola. (Tab. XX., fig. 24 <? .) : 



Lampides viola, Moore, Ann. & Mag. Nat. Hist. ser. 4, vol. xx. p. 840 (1877); Lep. Ceyl. i. p. 80. t. 88, 

 f. 1, la, J (1881). 



Male. Wings above dark violet-blue, with a slender black marginal line 

 and the fringe pale fuscous. Wings beneath greyish-brown ; anterior wings 

 crossed by the following narrow greyish fascife arranged in pairs, viz. : — -two 

 crossing cell and continued beneath it, two short and disco-cellular at end of 

 cell, two between end of cell and apex of wing (the innermost terminating at 

 central median nervule), and a pair situate between the last two series com-

mencmg at upper median nervule and continued to near abdominal margin, 



and a marginal and two submarginal narrow greyish fascife. Posterior wings 



crossed very irregularly by about sis narrow and broken fasciae, as on anterior wings, and a narrow 



marginal and two much-waved similar submarginal fasciae ; a large black marginal spot margined with 



dark ochraceous and speckled with metallic greenish, between second and third median nervules, and 



a somewhat similarly coloured anal angular streak. Body above and beneath more or less concolorous 



with wings. 



Female. This sex is figured by Mr. Moore in tbe ' Lepid. Ceyl.', and described as "dark violet- 

 lirown, smalt-blue on middle of the forewing ; hindwing with indistinct marginal row of pale-bordered 

 black spots, the penultimate spot most distinct."' 



* Lyccena atrata, Horsf. " Cat. Lep. E. I. C. p. 78, n. 13. f Ann . & Mag. Nat. Hist. ser. 4, vol. xx. p. 341 (1877). 



I The figure liere given is very unsatisfactory, if not quite misleaiUng. At the time when the plate was executed I had 

 not received the species from the Malay Peninsula, and was indebted to Mr. Moore for the loan of a Malaccau si^ecimen to 

 figure. This specimen was a much rubbed one, and hence our artist, in his effort to conscientiously pom-tray the species, has 

 rendered the upper surface uf the wings too strongly shaded with brown. ]Mr. Moore's figm'es of the male in the ' Lep. Ceylon ' 

 is equally imsatisfactory, not showing the markings beneath. I have therefore added a good woodcut.
