﻿NYMPBALIN^. (Gronp POTAMINA.) 43 



subcostal fork, and rapidly narrowing to the inner angle, and with an indistinct sub- 

 marginal series of small roundish white spots placed upon the inner edge of the 

 narrow black-brown outer border, and extending from the inner angle up to the 

 third median nervule. Eindwing black-brown of a richer tint, broadly and inter- 

 digitatingly bordered externally with clear cinnamon-brown, which is traversed by 

 the dark brown veins, and bears, midway between the black base and the wavy 

 purplish-black narrow outer border, a series of four impressed white specks all 

 encircled internally with black-brown, one in each interspace from the first median 

 to the second subcostal nervule, and, at its junction with the wavy black outer 

 border, a similar but more complete series of white specks, two to each interspace 

 (except the second, in which there are four, the middle one of the three being 

 divided) from the internal nervure to the first subcostal nervule, and all roundish, 

 except the first two, which present the form of linear marks parallel to the outer 

 margin. Underside. Both wings cinnamon-brown, narrowly bordered externally 

 with purplish black-brown, with the veins rich dark brown, and the submarginal 

 spots more numerous and distinct than above. Foreiving slightly darker for the 

 basal two-thirds, with a short streak of pale lilac between the first and second 

 median nervules near the base of the cell, and an ill-defined roundish clump of scales 

 of the same colour beyond it, an externally forked streak of dark violet-blue occupy- 

 ing the basal two-thirds of the interno-median area, and followed by an indistinct 

 clump of violet-grey scales, a grey streak in the apical half of the inner margin, and 

 a submarginal series of violet-white spots situated upon the inner edge of the black 

 outer border, and extending from the inner margin to the apex, with all the spots 

 round, except the first six (which have the form of linear streaks) and the last, which 

 is elongate, and arranged two in each interspace except the eighth from the apex, in 

 which there are three, and the last, in which there is only one. Hindwing uniformly 

 coloured, with a discal series of seven violet-white spots and dots, arranged in two 

 series, an anterior curved one of three, and a posterior straight one of four, the 

 three foremost of which latter, with the last of the anterior series, coincide with the 

 four impressed spots of the upperside ; and with a submarginal series of spots of the 

 same colour, situation, and extent as in the fore wing, but differing somewhat in shape, 

 the last three being linear streaks parallel to the outer margin, and the rest more or 

 less elongate, and those of each pair divergent externally as if they were the remain- 

 ing outer ends or horns of lost lunules " (W. Mason, I.e.). Mimics the Euplteine 

 butterfly Penoa Alcathoe.
