AMBLYPODIA GROUP OF THE LYCMBHDM. 123 



is not present in the primaries, and it will be interesting to note whether that is constant 

 in the Bornean form. The species can readily be separated from A. ace de Niceville by 

 the broad borders to the primaries and the difference in the pattern beneath. My 

 female from Kina Bain is apparently the only specimen of that sex yet taken.

 Arrhopala ace de Niceville and Martin, J. A. S. B. vol. lxiv. pt. 2, p. 464. n. 390 (1895). 



Hah. Perak ; Sumatra. 



Expanse. 6 , 4(3-55 mm. 



The female of this species is at present unknown, but the insect is a strongly 

 marked species and can be separated from azinis de N. by the quite different colour 

 of the upperside and by the linear markings beneath. 



Arhopala agrata de Niceville. 

 Arkopala agrata de Niceville, Butt. India, vol. iii. p. 251, frontispiece fig. 137, J 1 (1890). 



Hal. Singapore ; Java ; Burma. 



Expanse, 2 , 4S mm. 



I have not seen the types of this species, but Mr. de Niceville has kindly lent his 

 entire collection to me, in which are one specimen from Singapore and two from 

 Burma ; the types from Singapore are in the Raffles Museum at Singapore, which he 

 (Mr. de Niceville) describes as of the same colour as teesta de Nicev. (i. e. hazalus Hew.) ; 

 the specimens before me, however, are by no means so deep in hue, being of a more real 

 purple with less of the brown shade ; this, of course, may be an individual aberration, 

 but it is advisable to notice it. The underside pattern is somewhat near that of A. ace 

 de Nicev., but the transverse band of the primaries is narrow and continuous, whilst iu 

 the latter species it is broad and distinctly fractured below the fourth spot ; the 

 markings are also very obscure indeed, which is not the case with ace, and the 

 colour of the upperside of the latter is totally different. 



Arhopala detrita (Staudinger). 



Amblypodia detrita Staudinger, Iris, vol. ii. p. 129 (1889). 



Hub. Palawan. 



Expanse, 6 , 30 mm. 



This species was described by Staudinger from an unique specimen, but it appears to 

 be fairly distinct from agrata de Nicev. ; it may be known by its much smaller size, its 

 brighter blue, its broad borders, and beneath by its transverse bands being straighter 

 and in the primaries entirely unfractured.
