The butterfly given as Spalgis Epius by Courvoisier, captured by Jacobson 

 on Nousa Kambangan (20) on the south coast, is in all probability this species. 



When alive, the butterfly has very light green eyes. I received the pupa 

 attached to a young dadap leaf (Erythrina Hypaphorus Boerl.) and on a 

 touri leaf (Sesbania Grandiflora Poir) and I was told that the caterpillars 

 lived upon such leaves. I have not observed this myself, and of a very nearly 

 related species, upon which E. H. Aitkin has written a paper entitled " The 

 Larve and pupa of Spalgis Epius Westwood" {Journ. Bombay Nat. Hist. Soc. VIII), 

 De Niceville says that the larva is carnivorous and feeds upon Schirzoneurinae. 

 The pupa is very small, and bears a remarkable resemblance to a monkey's 

 head. It is too small to make a drawing of; I give, therefore, one taken from 

 an enlargement of the pupa, in which of course, this resemblance is lost, just 

 as the face on the moon disappears when a picture is made of the enlarged 

 disc. The resemblance does not of course really exist, but is only due to 

 defective observation, occasioned in this case, by the smallness of the pupa. 

 In the paper above referred to there are what the author calls two greatly 

 magnified illustrations of such pupae, of nearly related species, in which the 

 resemblance to a monkey's head is very striking. But this is only imaginary, 

 the illustrations only give an enlargement of the impression which the draughts- 

 man got when he saw the pupa, but not what enlargement really shows us, 

 where the resemblance is destroyed. The same applies to the enlarged repro- 

 duction given by Moore. 



Genus TARAKA de Nic. 



It seems that the certainly very ancient evolutionary process which causes 

 the fore-legs of the Rhopalocera to gradually disappear, and which in the 

 Lycaenidae has so far only attacked the tarsi of the male, is not in the same 

 stage in the genus Taraka as in the other Lycaenidae. The data of different 

 observers on this point do not, however, agree, and I am not in possession of 

 sufficient material to enter into an investigation of the subject.
