A female specimen from Province "Wellesley is here figured. The smallest specimen 

 which I possess (58 millim.) is from West Africa, although ordinarily sized specimens are 

 generally received from that district ; the largest specimens in my collection are from Northern 

 India and Southern Africa, though no rule can he postulated in tins respect. Figures of both 

 the larva and pupa of this insect have been given (ante pp. 2 & 3). 



The larva in Ceylon feeds on Ctihtrofus tjhjmttf.a and Aschpim curusacica ;* in Java, 

 according to Dr. Horsheld, on the hist named, called by the natives ** Widuri" ; in Continental 

 India on Catohvpis sp.;| and hi 8. Africa on titimplioatrpux fruticoMis and Astlepias sp. J 



This species is not only remarkable fur its wide distribution, but also for the extraordinary 

 phenomenon of its being miwicktid by six or eight other butterflies and moths, a fact which 

 will be treated more fully subsequently when describing some of the mimicking speeu-s.

Autemiaj gradually clavate. Wings opaque and dark coloured. Anterior wings more or less triangular 

 aiul varying mucb in shape, hut in the male sex generally having the inner margin more or less produced 

 and convex, and covering Home basal portion of thu posterior wings; in the female sex the inner 

 margin is non-produced and sometimes slightly einaryinate. § First subcostal nervule emitted at some 

 little distance before the end of the cell, second emitted at end of cell ; upper disco-cellular nervule shortest. 

 Posterior win^s LviukI and suhtiiaugular : costal nervure somewhat short, and curved near base. 



Hides usually provided with one en- more psendo-scent glands or brands on anterior wings, and very 

 frefpteiitry with a pale diseoidal patch to posterior win^s. 



Awaiting Mr. Moore's intended enumeration and revision of the genus Enphva (as formerly 

 and in this work understood), wherein many new species are to he described, it would prove 

 misleading to give any approximate estimate as to the number of species comprised in this very 

 extensive genus. 



Euptcta is widely distributed throughout the Malayan Archipelago and Polynesia ; in fact, 

 we may accept these regions as the head-quarters of the genus. It is likewise found 

 throughout the warmer parts of Asia (including its neighbouring islands) and Australia; it 

 also inhabits the islands of Mauritius. Bourbon, find Madagascar. Trimen|| gives South 

 Africa as the habitat of a species (E. gotufotu, Boisd.), from specimens contained in the British 

 Museum. As, however, Butler, in his two subsequent papers on the genus, does not give 

 that habitat for the Museum specimens, South Africa may be considered for the present as 

 a doubtful locality. 



The short vitt& so frequently found on the anterior wings of the males, have been,
