variety of eridanus Feld. Dr. Holland says it is like polita Rober (a synonym of 

 eridanus), but the spots below, instead of being round, are elongated transversely. In 

 many species of this genus I have noticed that the spots are occasionally liable to this 

 curious malformation.

Hah. Khasia Hills. 



Expanse, <s , 38 mm. 



This species can be recognised at once from its neighbours by its small size and the 

 quite distinct pattern of the under surface. It was described from a unique male 

 specimen in the collection of Mr. Moore, which specimen is unique to the present 

 time.

6 . Upperside : both wings violaceous blue, slightly lustrous ; primaries with a narrow 

 black costa and very broad apical area and posterior margin, the latter becoming 

 narrower at the anal angle ; secondaries with costa broadish black, and posterior 

 margin narrow ; abdominal fold grey ; from the submedian nervure up to the upper 

 discal nervule is a marginal row of black lunules decreasing in size. Underside : both 

 wings darkish brown, spots rather darker than ground, encircled, or partially so, with 

 whitish. Primaries with two basal spots ; the third closing the cell is not margined at 

 its costal or anal edge with white, but occupies a large irregular area from the second 

 subcostal to the lower median nervule ; the transverse fascia consists of four confluent 

 spots outwardly inclined, below which are three more confluent spots shifted inwards 

 and reaching almost to the inner margin ; submarginal lunular row distinct, extreme 

 margin finely edged with white ; there is a small light patch near the anal angle on 

 the inner margin. Secondaries with half a spot on the extreme upper basal edge, the 

 white border of which extends shortly along the costa ; beyond and below this are the 

 four basal spots, the lowest shifted inwards on to the internal nervure ; outside these 

 are three largish spots, the top one of which is not margined with white on its costal 

 edge ; cell shifted inwards. Chain-like fascia very irregular, the second spot shifted 

 outwards, the third still further outwards, the fourth outwards somewhat again, fifth 

 well inwards, sixth slightly outwards, the seventh spot at angle inwards, touching the 

 long final spot, which nearly reaches the lowest basal one. This fascia is not absolutely
