Lepido'ptcra from the White Nile. 153 



169 ; PL VII, lig. 7. It was collected on the White Nile 

 by Petherick. The second is Captain Dunn's, and was 

 captured in 1900 on the Bahr-el-Zeraf (Giraffe River, 

 White Nile). The former is much the more heavily 

 marked. Mr. Loat's male corresponds rather with the 

 second specimen, which has more sharply-pointed and 

 narrower wings tlian the type, and probably belongs to 

 the dry-season phase of the species. The male appears to 

 be hitherto undescribed. 



rinacopUryx vemtiis, Butl. — Male. — General aspect somewhat like 

 that of P. Ulianti', Grose Smith ; Ijiit smaller, and with fore-wings 

 narrower and more sliarply pointed. 



Esp. al. 40 mm. 



UpjKr surface : — Wings white. Fore-whujs with inner third of costa 

 and basal lialf of cell greyish ; a marginal black point at tlie 

 extremity of the third median branch, and marginal black spots at 

 the extremities of the iirst and second median, the two radial 

 branches, and the third subcostal. These spots increase in size from 

 behind forwards, and those belonging to the first radial and the 

 subcostal branches Ijecome fused, together with a costal spot, into a 

 dark apical patch, in which however the separate constituents are 

 still visible. A thin dark costal streak ignites the apical black patch 

 with the basal grey. In the liiud-wing, the marginal extremity of 

 each vein or branch, except the internal, is marked by a small black 

 spot ; the spots belonging to the second subcostal, radial, and second 

 and third median, are somewhat linear, being elongated in the 

 direction of the vein. Lower surface: — Fore-wings vfhiie, slightly 

 greyish along costa and towards base ; a small roundish black spot 

 on lower disco-cellular venule. A fuscous mark, wedge-shaped with 

 the base uppermost, passes downwards from the second subcostal 

 near its termination to the space between the first and second radial 

 veins, crossing tlie common trunk of the thiixl and fourth subcostals ; 

 and a large roundish dark spot is situated between the second and 

 third median branches, about half-way between cell and margin. 

 All the veins and their branches, except the submedian, are beset 

 near the margin with a slight powdering of fuscous scales, which at 

 the extremity of each vein or branch become collected into a more 

 or less definite spot. Hiiid-tvings creamy white towards base and 

 costa, elsewhere white like the fore-wings ; costa edged with pale 

 yellow. A dark oval spot, several times larger than the discoidal 

 spot on the fore- wing, occupies the anterior half of the lower disco- 

 cellular vein, the latter forming its long axis. There is a large 

 fuscous spot on the costa at the termination of the costal vein,
