This species, if it really does occur with Indian limits, is very rare ; we have never seen a 

 specimen. Distant remarks that "it appears to be almost confined to the Malay Peninsula, 

 especially if there should be any error in the locality of Assam, as given by Mr. Warwick to 

 the British Museum." It is nearly allied to. and probably is only the continental form of, 

 Euplxa viazares, Moore, from Java, of wliich a figure of the upper and underside of a male in 

 the Indian Museum, Calcutta, is given below :—

Fourth C";w//.— Trf.psichrois, Hiibner. — "Forewing elongated, :he outer margin sub- 

 angulated and slightly inarched below the apex ; the inner margin of the male very slightly 

 convex, without trace of a brand, but the hindwing with a small yellowish patch in the cell 

 at the origin of the first subcostal branch." {Butler, Journ. Linn. Soc, Zoology, vol. xiv, 

 p. 296, 1878). 



The elongated forewing distinguishes this group and the two following from the three 

 which precede. Only a single species of this group is found within Indian limits, and only 

 three others are known which represent the group in the Malay Archipelago. The fenr.ales 

 differ greatly from the males in having the hindwing profusely striped with white. The 

 Indian species extends from Burma through the Himalayas to Kulu, and is the widest spread 

 and commonest of all the Euplaas of Northern India, except E. core.

Description: Male: Upperside, y^A-t'ty/w^ deep velvety blackish-brown, glossed with 

 brilliant blue, brightest on the apical half, where it forms in some lights a large patch of this 

 colour. The basal half spotless, the outer half with numerous pale blue spots, powdered and 

 often centred with white, and arranged as follows : — A marginal row of small spots, regular, 

 two between each pair of nervules, decreasing towards and seldom reaching the apex ; a 

 submarginal row of larger spots, irregular, one between each pair of nervules ; a discal row, 

 very irregular, of seven spots, and angled at two points, commencing with a small costal spot, 

 and ending with an oblong interno-median spot ; and one spot in the cell near the end. 

 Hindwing velvety brown, the costal area ashy testaceous, with a small yellowish patch within 

 the cell at origin of first subcostal nervule, otherwise entirely unspotted, though occasionally
