Miscellaneous. 183 



on page 83, with the following note : — " This very remarkable 

 insect is entirely unlike any other species which I have ever seen 

 from the African continent, and recalls in general appearance some 

 of the species of the S. American genus Entheus. At the time 

 Lieut. Watson prepared his Eevision of the genera of the Hesperiidae, 

 no specimen of this insect was available by him for purposes of 

 study. I take pleasure in incorporating a cut giving the neuration. 

 From this it will be seen by the student that the neuration is quite 

 peculiar, and that Mons. Mabille, the author of the genus, was 

 abundantly justified by the facts in erecting it for the reception of 

 the typical species." 



A reference to "Watson's paper, Proc. Zool. Soc. 1893, p. 130, 

 shows CJionstoneui-a, Mab., type ajncalis, Mab., among the genera 

 " of which the types are not in the British Museum," and which 

 consequently he was " unable to identify." 



If the student compares together the excellent figure of Choristo- 

 ne%ira apicalis, Mab., in Proc. Zool. Soc. 1896, pi. v. f. 1, and 

 Mabille's very short description of his species in Bull. Soc. Ent. Fr. 

 (6) vol. is. p. clvi (1889), with Butler's description oi Astktoptencs 

 Johnstoiiii, Proc. Zool. Soc. 1887, p. 573, he will at once notice that 

 figure and description refer to the same form, which must therefore 

 stand as Johnstonii, Butler. 



A similar comparison of Mabille's slight definition of CJiorisfoneura 

 in the ' Bulletin,' and the cut of neuration given by Holland on p. 83, 

 Proc. Zool. Soc. 189G, with Watson's more detailed definition of 

 Katreus, P. Z. S. 1893, p. 1 15, will show the identity of Chorlstoneura 

 and Katrens. 



Karsch, in the communication referred to above, had recognized 

 his own Loxohxis percnoptera from Barombi as a synonym of Choristo- 

 neura apicalis, Mab., by the aid of the figures given by Holland. 



The species will thus stand as Clioristoneura Johnstonii, Butler 

 {apicaUs, Mabille), and the fuller synonymy will be : — 



Chorlstoneura, Mabille, Bull. Soc. Ent. Fr. (6) ix. p. clvi (1889). Type 



apicalis, Mabille. 

 Katreus, Watson, Proc. Zool. Soc. 1893, p. 115. Tvpe Jvhnstonii, 



Butler. 

 Loxohxis, Karsch, Eiit. Xachr. xxi. p. 320 (1895). Type percnoptei'a, 



Karsch. 



Astictoptertis Johistonii, Butler, Proc. Zool. Soc. 1887, p. 573. 



Choristoneura apicalis, Mabille, Bull. Soc. Ent. Fr. (6) ix. p. clvi 

 (1889). 



Katreus Johnstonii, Watson, Proc. Zool. Soc. 1893, p. 115 (nee Hol- 

 land, Ent. News, v. pi. i. f. 8, 1894 ; nee Holland, Proc. Zool. Soc. 

 1896, pi. ii. f. 18). 



Loxolexis percnoptera, Karsch, Ent. Nachr. xxi. p. 321 (1895). 



Choristoneura apicalis, Holland, Proc. Zool. Soc. 1896, pi. v. f. 1. 



From the plate alone I am unable to say to what genus we must 

 assign the species figured as Katreus Johnstonii by Holland, Ent. 

 News, v. pi. i. fig. 8 ; but if the species prove new, it should certainly 

 be described by the learned doctor, who in his recent paper has 

 done so much to facilitate the study of the African Hesperiid 

 fauna.
