Neaveia lamborni, sp. n. (Plate XXXV. fig. 1, o .) 



Male. Upper side : both wings uniform creamy white with a 

 faint greenish tinge, slightly opalescent at the base of the hind 

 wing. The basal half of the costal margin of the fore wing is 

 pale brown, merging into the blackish-brown apical and outer 

 margins. Under side pale opalescent greenish white without 

 markings, but slightly yellowish over the discal area of fore wing. 

 Cilia of both wings on both surfaces fuscous except towards the 

 apex of the hind wing, where it is white. Thorax clothed Avith 

 white hairs ; abdomen yellowish white above and below. Antennae 

 black with minute white spots. Palpi deep black, shining, second 

 joint inwardly clothed with pale brown hairs. Legs black with 

 pale brown patches. 



Expanse 1| inch. 



Hob. Oni, 70 m. east of Lagos, W. Africa (W. A. Lambom) * . 



Type, Hope Coll., Oxford University Museum. 



The specimen described above has a number of small black 

 spots irregularly placed over the dark apical area of the upper 

 side of the fore wing, but as those on the right wing are not 

 placed in the same position as those on the left wing, I am 

 inclined to believe that they are due to some external cause. 

 The outer margin of the hind wing has, on both surfaces, a few 

 brown scales which seem to point to the fact that it has lost, 

 or is acquiring, a dark marginal border. The insect's Pierine 

 appearance is very marked, and Mr. Lam born is to be congratulated 

 on a very interesting capture. 



Epitola batesi, sp. n. (Plate XXXIV. figs. 2 J , 3 5 .) 



Male. Upper side : fore wing uniform rich blue with the 

 apical third evenly deep black. Cilia black, white at the angle. 

 Hind wing uniform rich shining blue, costal margin evenly and 

 broadly dull black ; inner margin dark grey. A black anteciliary 

 line, slightly thickened at the extremity of the nervules. Cilia 

 white. Under side silvery ashen grey with pale bluish-grey 

 markings. Both wings with a marginal and a submarginal row of 

 crescent-shaped lunules. Fore wing with a central circular band 

 of markings commencing on the costa where they are small, and 

 continuing to the anal angle where they become large patches. 

 Hind wing : discal area covered by a number of small irregular 

 markings. Thorax and abdomen black above, pale below. 

 Antenna? black above, white-spotted below. Palpi cream, terminal 

 joint black. Legs black with cream spots. 



Female. Upper side : fore wing white with the apex and outer 

 margin rather broadly blackish brown ; basal area including 

 upper part of cell and costal margin dark grey, more or less 

 suffused with pale blue scales. Inner margin very narrowly grey 



* In a letter recently received from Mr. Lamborn he states that he captured this 

 insect in the wet Season, at dusk, on the veranda of his house.
