is bright blue over fully balf the forewing, its edge serrate, with a wide 

 brown border oa both wings, darkening where it borders on and deeply 

 indents the blue snbapically. The species is extremely uniform every- 

 where, and is abundant from Tavoy and Mergui to south-eastern 

 Borneo. 



18. Arhopala HELiiENORE, n. sp., Plate XXIII, Fig. 7. 



Nearest e?Mno/p/iws, The green of the upperside is rather more 

 tinged with golden, and the dark border is somewhat narrower on 

 the forewing and much narrower on the hindwing, extending less 

 than a third towards the base of the lower median space. Below both 

 wings are conspicuously marked with whitish, which foi'ms a large apical 

 mass on the hindwing in which the transverse markings are very dis- 

 tinct, and across both wings in an obscure discal band. The subanal 

 metallic green markings are obsolescent. The dark markings are large, 

 as in farqnhirii, from which it seems quite distinct, though it may be 

 the local Tenasserim form of eumolphus. One male, Mergui. Expanse 

 1~ inch. 



19. Arhopala maxwellti. Distant. ( ? ). 



1 am uncertain whether, as Mr. de Niceville suggests, the female 

 taken by Mr. Biggs and figured by Mr. Distant as A. maxwellii, is really 

 the female oi farqnharii, or whether, as I thought at first, it is the female 

 of a male taken by me at Myitta. This is a dark violet-blue butterfly, 

 very much like agaba above, but singularly like farquharii below, distin- 

 tvui'shed, however, by the large distinct basal spots of the hindwing, the 

 large costal spot of the forewing opposite that at the end of the cell, and 

 bv the first four spots of the discal band forming a very regular quadrate 

 mass Neither by the figure nor the description can I distinguish it 

 from maxwellii. But Mr Distant is much more likely to have obtained 

 far-quharii, which is abundant, than this species, which is rare, and Mr. 

 de Niceville's theory is probably correct. In that case my male remains 

 unidentified.* 



20. AuHOPALA (Satadra) agaba, Hew. 

 Myitta, Tavoy. 



21. Arhopala (Satadra) aida, de Nice, MS. 



- Mergui, a very common species. In typical species of Satadra, such 

 as atraa: and rama, the tail and lobe are well developed, but in others 

 they tend to disappear, so that it would be hard to define the genus. 



22. Mahathala ameria, Hew. 

 Mergui, Myitta, common. 



* Since tliia was written I liave learned that Mr. de Niceville will describe this 

 species as Arhopala adorea,
