and upwards to the cell. On the under side the outer margins 

 of both wings are entirely without the broad orange bands. 



Female. On the upper side the orange area of the fore wing 

 is more extensive than in the typical form and the hind wing 

 is entirely orange, excepting at the base. Under side as male.

Mr. Bates obtained a good series of this species, all of which 

 differ from the typical form as described above. 



Lycjlnesthes. 



The new forms in this genus described here and the two 

 following have been submitted to Mr. Betliune-Baker, who has 

 lately written a monographic revision of the African species of 

 this group, and he agrees with me that they are undescribed. 



LyCvEnesthes mimetica, sp. n. (Plate XXXIV. fig. 11, $ .) 



Female. Upper side pure white ; apical half and costal border 

 of fore wing dark brown ; hind wing with outer margin dark 

 brown supporting a marginal row of triangular black spots ringed 

 with pure white and of varying size, the two largest being placed 

 between veins 2 and 3, and 3 and 4. A dark brown anteciliary 

 line. Cilia of both wings brown. Under side : fore wing 

 white ; apex and outer margin pale brown with a marginal 

 and submarginal row of slightly dark lunules. A double brown 

 mark closing the cell, and another, broader, near the centre of 

 cell 1. Hind wing white, the apex and outer margin brown 

 as on fore wing and with the marginal row of lunules as 

 described on the upper side, the two larger ones only being 

 black ; at the extreme anal angle is a small orange spot. A 

 double brown mark closing the cell. A small black spot near 

 the centre of the costal margin, another near the base, and a 

 third on the extreme anal margin towards the base. Thorax 

 and abdomen brown above, white below. Legs black and white, 

 Palpi white with black tips. Antennae black, ringed with white.

Not closely allied to any described species. 



Lyoenesthes bitje, sp. n. (Plate XXXV. fig. 15, $ .) 



Male. Upper side dark brown ; fore wing with a rather large 

 discal ovular orange spot ; hind wing with an ultra-medial 

 orange fascia, a pale anteciliary line, and a black, red-crowned 

 marginal spot in cell 2. Under side pure white, with com- 

 paratively few brown markings and those broad and clearly 

 defined. Fore wing ;. a long cellular streak, a broad band crossing 

 the cell and reaching the inner margin, a dentate spot closing
