reproduction of a photograph of the various species I trust will 

 be of assistance to those who are engaged in the study of this 

 somewhat difficult group. 



N. Biafra Ward, var. continuata var. nov. rj.— Agreeing with Biafra 

 in all respects save in the form of the band of large white spots which 

 traverse the anterior wing beyond the cell. In Biafra the three nearest 

 the costa are long and linear and the two following are oval, divergent, 

 and somewhat widely separated from the spots nearest the costa. In 

 contmuata the spots form a continuous uninterrupted band, in which all 

 the spots, except the lower one, which is suboval, are subquadrate. The 

 difference in the form and spacing of these spots imparts a widely diiTerent 

 facies to this form. It is worthy of note that the transverse spots in the 

 cell of the primaries of Biafra are not constant. In some specimens they 

 are very faint, and in some altogether wanting. 



N. nicobnle sp. nov. (^. — Allied to A''. 7iicoteles Hew. The markings of 

 the upperside of the anterior wings differ from those of N. nicoteles in 

 the form and arrangement of the transverse white spots beyond the cell, 

 which in nicoteles form a continuous band, and in nicobnle a widely sepa- 

 rated series of four spots, of which the one nearest the costa, and the one 

 opposite the end of the cell are minute, while the two middle spots are 

 large and oval. The marginal lines are interrupted below the ape.x, and 

 near the middle of the outer margin by dark longitudinal shades. The 

 spot of the transverse series situated upon the hind margin of the anterior 

 wings in nicoteles is large and bifid; in nicobnle it is simple, and consists 

 merely of a small subtriangular patch of bluish white scales. Upon the 

 underside of the primaries of nicobnle the dark shading which interrupts 

 the marginal is much more distinct than upon the upperside, and there 

 are but three submarginal bands of white, while in fiicoteles there are 

 four. Expanse 43 mm. 



N. metanira sp. nov. (^. — Allied to A". Biafra Ward. — The wings are 

 narrower and more produced than in Biafra, and the margins are not 

 scalloped, but even. The transverse band of white spots beyond the cell 

 upon the primaries is composed of six spots, the one on the costa minute, 

 the three following large and fused together forming a transverse spot 

 indented outwardly upon the nervules. This is followed by two diver- 

 gent oval spots, of which the lower one is the smallest. The transverse 

 median band upon the secondaries is relatively narrower than in btafra, 

 and more deeply indented externally, and is clouded niternally by pale 

 fuscous. The submarginal lines are bright bluish. Upon the underside 

 the primaries have four marginal lines, while in Biafra there are generally 

 but three. Expanse 45 mm. 



N. mixophyes sp. nov. rf . — Belonging to the same group as nicoteles 

 and nicobnle, characterized by a long, uninterrupted, white longitudinal 

 ray traversing the cell from the base to its extremity. In mixophyes this 

 ray is acute at its extremity and not rounded as in the other species. The
