Lepidoptera from the White Nile. 155 
169; Pl. VIL, fig. 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 than the type, and probably belongs to 
the dry-season phase of the species. The male appears to 
be hitherto undescribed. 
Pinacopteryx venatus, Butl.—Male.—General aspect somewhat like 
that of P. Liliana, Grose Smith ; but smaller, and with fore-wings 
narrower and more sharply pointed. 
Exp. al. 40 mm. 
Upper surface :—Wings white. Fore-wings with inner third of costa 
and basal half of cell greyish ; a marginal black point at the 
extremity of the third median branch, and marginal black spots at 
the extremities of the first 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 become 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 unites the apical black patch 
with the basal grey. In the hind-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 white, shghtly 
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 the common trunk of the third 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. Hind-wings 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,
