BIDUANDIN^. 187 



species. Male, above, dark fuscous, an orauge area occupying about a sixth of the 

 forewing, including the lower angle of the cell, and the disc from the base of the 

 lower radial to below the lower median vein ; a somewhat large, obscure violet-blue 

 sub-apical area (not refulgent in any light), not reaching the costa or the outer margin ; 

 the hind margin is also tinged with violet. Hindwing dull fuscous, a large dull violet 

 area from the cell to the outer margin, between the lower sub-costal and the lower 

 median vein, from the cell to the marginal black line, its inner part densely irrorated 

 with bluish-white scales, beyond which lies a transverse darker discal fascia ; sub-anal 

 area nearly black. Cilia whitish sub-anally ; tails chiefly black, except at the tips. 

 Underside much as in thesmia, expanse as in melisa. One male, Mergui. 



I name the species after Mr. S. H. Scudder, of Cambridge, Massachusetts, the first 

 numbers of whose magnificent work on the New England butterflies I have just had 

 the good fortune to meet with. (Doherty.) 



Expanse of wings, $ 1 inch. 



Habitat. — Mergui. 



We have not seen this species, and have been unable to ascertain where the type 

 now is, we therefore give a copy of Doherty 's figure.

Imago. — Male. Upperside. Forewing black, tinged with purple. Hindwing with 

 the costal space rufous-ochreous, abdominal fold brown, the anterior half of the wing 

 purple-black, the lower portion bright shining blue, a narrow black band down the 

 outer margin, fining hind wards to the outer tail, and continued in a fine line to the 

 inner tail, a black sub-terminal lunule in the first median interspace, and another in 

 the next inner interspace, each with a white line between it and the terminal black line ; 

 tails black, tipped with white and with white cilia. Cilia of forewing and apical portion 

 of hindwing black, the rest of the cilia of the hindwing white. Underside milky-white, 

 markings dark chocolate-brown. Forewing with the apex broadly suffused with 

 chocolate-brown, the lower half of the outer margin with a pale orange-red band 

 limited by a dentate sub-marginal line, a sub-basal spot in the cell, with a smaller one 

 below it, a larger spot in the middle of the cell, with a smaller spot below it, a line at 

 the end of the cell, with a large squarish patch that runs up to the costa, close outside 

 it, the entire costa from the base to this patch with small spots, a lunular discal line
