my stay it was nut at all conuuou, and I took but two (oiie very large 

 and fine) and saw one or two others. 



The Pierinai were unquestionably the dominant group. The first 

 of them to attract attention was Catopsilia floreUa, F., of which I took 

 5 (J and 10 ? ; it was qiiite 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 (^ and 19 $ w^ere taken; some of the specimens 

 of both sexes were very small. One $ resembled a J in appearance. 

 In some of the males I detected a slight scent, once described in my 

 notes 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 the four wings. 



In the bean fields near the junction of the Blue and White Niles 

 Colias marnoana, Eogenh. (a miniature edition of our C. hyaJe), was 

 common. In all fifteen were taken, including tw^o white females. 

 Two examples had symmetrical injuries affecting all fom* 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 in one case the scent was noted in a 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 

 of T. ephijia, Klug, I secured four males and a female, missmg several 

 others ; two of the males were veritable dwarfs. I also took a single 

 dwarf male of T. daira, Klug. To the west of the towA I took the 

 only T. chrysoriome, Klug, a ? , that fell in my way. Lastly, I caught 

 near the tennis-ground a female of T. protomedia, Klug, which seemed 

 to me to have a faint scent like opium. At Burri I secured a specimen 

 of the very beautiful Callopieris eulimine, Klug. 



I did not come across a single Satyrid or Skipper in the Sudan ! 

 There was but one Nymphaline — the ubiquitous Pyrameis cardui, L., 

 which was met with in the largest numbers on an exposed piece of 

 ground at the very point of junction of the two rivers, exactly where 

 one would have expected to see it. A fresh brood made its appearance 

 on February 7th ; one of these, a male, had an unusual under- side, 

 very grey in tone, with but little dark shading, and without any black
