distinctly of the wet-season form, the female “‘ wet’ or 
“intermediate.” 
In 1912 I took a male at Kiré, another at Lado, also a 
male and two females at Gondokoro. 
As butterflies of the genus Terias are quite easily seen 
when on the wing, it might appear allowable to conjecture 
that brigitta does not extend far north of Lake No [Lat. 
9° 30’ N.], but the fact that specimens of the preceding 
species turned up no less than three degrees north of that 
place makes one cautious. 
T. brigitta is found in Abyssinia, Somaliland and through- 
out tropical and South Africa. 
68. Colias hyale, auctorum, f. marnoana, Rogenh. 
In 1909 I found this butterfly almost abundant in the 
beanfields at the junction of the Blue and White Nile, just 
below Khartiim, near a village called Mogran. 
During my visit in 1912 I did not work that exact 
locality, but I netted two males at the edge of a large 
cottonfield at Kadari, opposite to Kerreri, and a few miles 
to the north of Kharttim. 
Peel took a female in Somaliland in 1897. It is fairly 
common at Port Sfidin, and it occurs in Abyssinia, but 
Col. Yerbury tells me that the genus has no representative 
at Aden. 
C. hyale is very widely distributed over the Palaearctic 
region. 
Sub-family PAPILIONINAE. 
69. Papilio demodocus, Esp. 
Taken by Dunn on the Bahr al-Zaréfa; by the Swedes 
at Khartiim, where the Rothschild party found it abundant 
among lemon trees. 
I saw but few at Khartiim in 1909; at the time of my 
second visit, however, it was quite common among limes 
(Citrus limetta). 
Mr. H. H. King assured me that demodocus is found up 
the White Nile, but could give no particulars. 
Selous took two at Ardeiba in the Southern Bahr al- 
Ghazal. It occurs at Aden, also in SomAliland, and is 
found throughout tropical and South Africa. 
70. Papilio pylades, Cramer. 
Loat took a female at Gondokoro, noting it as “ rare.”
