920 DE. A. G. BULTER ON BUTTERFLIES [Dec. 4, 



Of the four males Mr. Crawshay writes : — " 1 am somewhat 

 puzzled to know whether this aud the three following specimens 

 are or are not identical as species with the two foregoing insects. 

 I am inclined to think not, as not ouly are their markings different, 

 but the former are larger than the latter." Of the two females 

 (which are the larger aud differently marked specimens referred 

 to in the preceding note) one example is much shattered, and 

 Mr. Crawshay thinks it "has probably weathered several 

 seasons." 



26. Atella phalantha. 



Papilio phalantha, Drury, 111. Exot. Ent. i. pi. xxi. figs. 1, 2 

 (177U). 



Roromo, Kikuyu forest, Jan. 12, 1900. 



" Elsewhere a common enough species. Here not common nor 

 easily taken, since it is always travelling in desperate haste, with 

 its swift, straight flight, turning neither to the right nor the left." 

 (R. C.) 



27. Argynnis hanningtoni. 



Argynnis hanningtoni, Elwes, Trans. Ent. !Soc. London, 1889, 

 p. 558. 



Itugi, 7400 feet, Kikuyu, Oct. 2; Loromo, 7700 feet, Oct. 5 ; 

 Roromo, Nov. 11, 23, 30, 1899. 



The series of this interesting species now sent home by Mr. 

 Crawshay fully bears out the constancy of the characters upon 

 ;vhich 1 distinguished my A. excelsior. Considering that our 

 series of the latter consists of eleven specimens from Ruwenzori, 

 all showing the same characteristic differences of form and 

 colouring, I cannot comprehend the meaning of the term " variety " 

 as applied to it by Aurivillius ; if he had said local, or representa- 

 tive form, it would have been comprehensible, but to my miud a 

 variety is a sport coexisting with the typical form. 



28. NEPTIS AGATHA. 



Papilio agatha, Stoll in Cramer's Pap. Exot. iv. pi. cccxxvii. A, B 

 (1782). 



6 $ , Ruarka River, 5500 feet, April 27, 1900. 



29. Xeptis trigonophora. 



Neptis trigonophora, Butler, Ann. N. H. (5) ii. p. 177 (1878). 



Var. Neptis lermanni, Aurivillius, Ofvers. Yet.-Akad. Forhandl. 

 liii. p. 431 (1896); Rhop. ^Ethiop. pi. 1. fig. 8 (1898). 



6, Ruarka River, 5500 feet, April 27, 1900. 



My type has a smaller white patch in the discoidal cell of 

 primaries than that figured by Prof. Aurivillius ; but this is clearly 

 a variable character, as the specimen obtained by Mr. Crawshay 

 shows no discoidal patch on the upper surface.
