been recorded from Ceylon, the Andaman or Nicobar Islands ; but from the Malay Peninsula, 

 Tmnos extends eastwards through the Malayan Archipelago to New Guinea. 



Two species are here figured and described, both of which appear to he confined to this 

 fauna. Another proposed species, described from Singapore* (jT. vhla t WalL), I take to be 

 synonymic with the second here enumerated. 



n. Posterior wing* not caudate.

Male. Wings above dark violaceous; anterior wings with a large dark brownish silky patch, which 

 uceupieH about [ipicnl bitlf of winy, but not extending above tbe discoidal uervults, except at outer margin, 

 where it is continued to apex, it also extends along inner margin to base ; posterior wings with a similar 

 but smaller silky patch broadly occupying apex and extending from costal margin to tbe lower subcostal 

 nervule ; two large white submarginal spots separated by the upper median nervule and a third almost 

 obsolete spot between the second and third median nervules ; narrow waved darker marginal aud submarginal 

 fascia? ; fringe greyish. Wings beneath of a steely-bluish colour, crossed by a number of dull reddish fascia], 

 of which five narrow and much waved cross both wings from base to a little beyond cell ; these are followed 

 by a broader and less waved fascia, which on anterior wings is succeeded by a macular fascia, of which the 

 upper spots are outwardly pointed, and one marginal and two narrow submarginal fasciae which become 

 fused at apex, and there contain a small white spot placed between the fourth aud fifth subcostal nervules ; 

 on posterior wings the central broad fascia is followed by one broader and more irregular, which contains 

 a series of castaneous spots placed between the nervules, one marginal and two submarginal fasciee, 

 between which the colour is greyish -white, aud the inner one of which is waved and at about centre 

 dentate, thus enclosing some apparently large augulated greyish-white spots. Body above concolorous 

 with wings ; beneath, with the femora, greyish ; tibue and tarsi ochraceous. 



Female. I only know this Bex by the description and figure of Mr. Butler. His diagnosis is as 

 follows: — "Alee supra fuscte ; area basali maeulis sex anticis discalihus inssqualibas inter venas positis 

 plagaque posticis discali purpureis nitidis; untica* fiiscii* duabus obscurioribus roquidistantibus fuscis 

 transversalibus : postica maeulis albis velut in mari, lumiiisijue alteris contiguis marginalibus albidis." 



Exp, wings, <? and ?. 63 to 73 millini. 



Hab. — Malay Peninsula ; Penaug; Province Wellesley (colls. Dist. and Sauer) ; Perak (Townsend — 

 coll. Dist*) ; Malacca (Pinwill — Brit. Mns.) : Ayerpanas (coll. Roberts) ; Singapore (Wallace). 



Although I have captured, received, and examined a large number of the males of this 

 species, I have not as yet seen a female specimen. Judging from Mr, Butler's figure, it is 

 rendered very distinct from the other sex by the possession of a broad central dark fascia on 

 the upper surface of both wings* 



* I have recently received a kindly worded remonstrance from Calcutta, that 1 Iihvc not included some species which 

 have by more than one author been ascribed to the fauna of Singapore. My reply must be the following: — There is Little 

 doubt, that formerly, and before the biological value of an exact habitat wae appreciated, much geographical error was 

 recorded on faulty or hasty information. Many inject b collected in Borneo and sent home from Singapore have had the last 

 locality averted as their habitat, and it becomes necessary, in the absence of specimens from that island, to require some 

 corroborative testimony. The insertion of an erroneous species in a fauna is calculated to do infinitely more harm to 

 biological science than the non-insertion of a true but unproved member of that fauna.
