islands the cranes stood in rows like soldiers, each kind by itself, in 

 scores or hundreds. Of pelicans we saw but few, of flamingoes possibly 

 one or two. Then there was the marabovit, which is a very handsome 

 bird ; so is the less common fish eagle. There were also kingfishers 

 and other smaller fowl. 



Crocodiles were common enough. We soon reached papyrus, at 

 first a plant or two, but later plenty. With the papyrus appeared the 

 hippopotamus. At one stopping place we were brought what we were 

 told was " lotus " — but it was not the Nelumhium, but a white water- 

 lily somewhat larger than our English Nymphaea alba, L. 



Later we entered a very scanty forest which appeared to consist 

 chiefly of acacias and other prickly trees. 



The first night, at Getena (63 m.), three Nodiix came to the 

 steamer's lights, all Egyptian species : — Agrotis segetiim, Schiff. ; 

 Caradrina exigua, Hiibn. ; and Sesamia \_Nonagria'\ cretica. Led. 



The following day, Feb. 17th, I got an hour and a half's collecting 

 in the middle of the day at Ad Duwem (125 m., lat. 14° 10' N.), but 

 unfortunately much of this precious time was wasted in looking for 

 good collecting ground. A female Polyommatus hseticus, L., two males 

 of Tamcus theophrashis, F., and a male of Azanus ubaldus, Cram., 

 were all Khartum friends, as were Belenois ^nesentina, Cram., a male, 

 Teracolus daira, Klug, of which I got one of each sex, and T.protomedio, 

 Klug, of which I also got one of each sex. The last is a strong flier 

 and I missed some in consequence. I did however add one species to 

 my list in the shape of Teracolus halimede, Klug (var. leo, Butler), of 

 which I got a male, but unfortimately damaged its hind-wing in 

 pinching it. I also got the common wasp, Eumenes tinctor, Christ, a 

 female, as well as Icaria cincta, Lep., also a female (Mr. Morice 

 regards this as qu.ite a tropical form) ; the Chrysid Parnopes viridis, 

 Brulle ; the fly Agria [Sarcophaga'] nuha, Wied. ; Coccinella 11-punctata, 

 L., ; and the widely distributed JJtetheisa pulchella, L., of which several 

 were seen. That afternoon, further up the river, a female Xylocopa 

 sestuans, L., came on to the steamer and was captured by Miss 

 Marriage. 



On the return voyage three days later (Feb. 20) , I got another two 

 hours ashore at Ad Duwem, from 8.45 to 10.45 a.m. Butterflies were 

 fairly common in and near some gardens a short way up stream, but 

 there was a strong wind and many of them were much torn. On this 

 occasion Danaida chrysippus, L., put in an appearance and I took a 

 male, a fine specimen of the alcippns form with hardly any fulvous
