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 van nov. $ . 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 

 continuata 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 different 

 fades 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. nicobule sp. nov. $. Allied to N. nicoteles Hew. The markings of 

 the upperside of the anterior wings differ from those of X. nitolcles in 

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

 which in nicoteles form a continuous band, and in nicobule 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 apex, 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\% large and bind; in nicobule it is simple, and consists 

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

 underside of the primaries of nicobule 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 nicoteles there are 

 four. Expanse 43 mm. 



N. metanira sp. nov. $. Allied to X. 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 Inafra, 

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

 fuscous. The submarginal lines are bright bluish, t'pon the underside 

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

 but three. Expanse 45 mm. 



N. mixophyes sp. nov. $. Belonging to the same group as 

 and nicol)n/e, characterized by a long, uninterrupted, white longitudinal 

 ray traversing the cell from the base to its extremity. In ;;//.r<y>/m - .v this 

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