THE SUDAN 
with it, since the Calotropis was in plenty; it would be interesting 
to know what form occurs there. The twenty-eight specimens 
brought home from Khartum may be classified as follows:— 
Typical chrysippits, 3 3 . 
chrysippus, but with the veins of the hind-wing dusted with 
white, 6 <J, 2 ?. 
f. alcippoides, Moore, 4^,2$. 
f. alcippus, Cram., 5 <£, 2 ? . 
f. dorippus, Klug, var. albinus, Lanzknecht, 1 3 (i>e. fore-wings 
lacking the transverse white bar, hind wings white). 
Of the total specimens seen, I estimated at the time that at least 
three-fourths were either alcippus or alcippoides . 
The musk-rat odour was evident enough in many examples, 
about equally strong in both sexes, but in one 3 the scent was 
compared to that of tobacco. 
The next most conspicuous butterfly was Papilio demodocus, Esp., 
I believe the only one of the sub-family that occurs there. During 
my stay it was not at all common, and I took but two (one very large 
and fine) and saw one or two others. 
The Pierinae were unquestionably the dominant group. The first 
of them to attract attention was Catopsilia florella , of which I took 
5 3 and 10 $; it was quite abundant along the river bank above 
Burri. One female was so unusually pale in colour as to resemble a 
male. Of the five males taken all had a sweet or luscious scent, 
in some faint, in others decided. 
Belenois mesentina, Cram., was also abundant, especially on culti¬ 
vated ground; 10 3 and 19 $ were taken; some of the specimens of 
both sexes were very small. One $ resembled a 3 in appearance. 
In some of the males I detected a slight scent, once described in my 
note as luscious, in others as musky; in two female specimens 
a slight musky scent seems to have been suspected. A male had lost 
a large piece out of each of its four wings. 
In the bean fields near the junction of the Blue and White Niles 
Golias marnoana, Kogenh. (a miniature edition of our C. hyale ), was 
common. Fifteen in all were taken, including two white females. 
Two examples had symmetrical injuries affecting all four wings. A 
slight scent was noted in some specimens, described as peculiar, 
chocolate-like, or clove-like. The observations were, however, not 
very definite, and the scent was noted in one female specimen. 
The prevalence of the genus Teracolus at Khartum was in itself 
sufficient indication that we were within the limits of the Ethiopian 
fauna. None of the species were really common during my stay, but
