is as in hurmana, the white markings reduced as above. 



B. M. Type No. Rh. 136, c?, Me Song forest, Prae, N. Siam, 



April 1918. 



A veiy distinct race. This species may always be readily 

 separated from those to which it bears a close resemblance on the 

 upperside, such as N. soma and N. ricmdina, by the absence of the 

 sub-basal streak, coupled with the far greater width of the basiil 

 streak on the underside of the hindwing.

 (Plate V, figs. 5 and 6.) 



6. Separable at once from E. m. perakana Fruhstorfer, its 

 nearest ally, by its larger size and the replacement of the broad 

 distal bluish-green band of hindwing upperside by a completely 

 bronze-green band, the anal angle alone showing some slight tinge of 

 bluish. In perakana such green as is present is confined to the 

 proximal half of this marginal band. ' The forewing also, especially 

 costally, basally, along the veins and distally in areas la to 3 strong- 

 ly bronze-green. Below, the ground- colour is a clearer brown than 

 in perakana, the discal dark markings more pronounced. 



2. Dark markings of both surfaces as in perakana female, 

 but not so heavy. Light markings larger, especially on hindwing, 

 and paler. 



Length of forewing. — 6 29 mm ; 9, 35 mm. 



B. M. Type No. Rh. 123, 6 ; 124, 2, Patani, Peninsular Siam. 



This new race of E. monina is particularly interesting, not 

 only on account of its being so very distinct, but also because it 

 appreciably extends the known range of the species. It has not 

 previously* been recorded as occuring north of Perak, so far as we 

 can ascertain. 



The Types, and only known specimens, were obtained by 

 Mr. W. A. Graham and by him presented to the British Museum.
