'^ Butterjlies from the Pacific Islands." 

 To the Editors of the ' Annals and Magazine of Natural History' 



Gentlemen, — In answer to Mr. Sclater's letter of December 2nd, 

 published in your last number, I have to make the following remarks. 



I find on referring to my edition of Mr. Keith Johnston's Atlas 

 that the Timor group, ]N^ew Guinea, and the Solomon Islands are all 

 included in his map of " The Islands of the Pacific Ocean " — so that, 

 it I have erred, I have erred in good company. 



I venture to think that Mr. Sclater's observations, in which he 

 accuses me of a " serious geographical error," are somewhat hyper- 

 critical. The islands in question, being situated in the Pacific 

 Ocean, may not inaptly be termed Pacific Islands, though they are 

 separated by more or less considerable distances from other groups 

 of islands, which are more in the centre of the Pacific Ocean. I am 

 not acquainted with any authority which restricts the term " Pacific 

 Islands " to these last-named groups ; but even though there be 

 such authority, I still think that the title to ray series of papers on 

 the butterfiies found in the numerous islands of Oceania, with the 

 last of which series Mr. Sclater has found fault, is sufficiently accu- 

 rate for the purpose for which the papers were written. They 

 were prepared for the perusal of entomologists, and I think I am 

 not far wrong in supposing that no entomologist would be misled 

 by the title, though such title might not, technically, satisfy a 

 geographer. 



The title appears to me adequate, and sufficiently accurate to 

 indicate to entomologists, in general terms, the quarter of the globe 

 in which the butterflies were captured. If this be so, my object in 

 thus designating my papers has been attained. 



I hope I may never be accused of a more "■ serious error " than 

 that which Mr. Sclater has attributed to me. 



I am. Gentlemen, 



Your obedient Servant,

Note on the Genera Choristoneura, Mahille, and Katreus, Watson. 

 By F. A. Hekon. 



Dr. W. J. Holland in his most useful " Preliminary Eevision and 

 Synonymic Catalogue of the Hesperiidae of Africa and the adjacent 

 Islands," in the Proc. Zool. Soc. 1896, p. 74, quotes the genus 

 Katreus, Watson, with its type species Astictopterus Johvstonii, 

 Butler, Proc. Zool. Soc. 1887, p. 573, and also a figure of his own 

 in the 'Entomological News,' vol. v., Jan. 1894, pi. i. f. 8, as 

 representing Butler's species, and gives a further reference to Proc. 

 Zool. Soc. 1896, pi. ii. fig 18. This figure was afterwards correctly 

 ascribed to Gorgyra abwce, Plotz, by Karsch in a note on Holland's 

 paper published "in Ent. Nachr. sxii. p. 377 (1896). 



On page 83 of his Eevision occurs tbe mention of the genus 

 Choristoneura, Mabille, a coloured figure of the type Choristoneura 

 apicalis, Mab., being given on pi. v. f. 1, and a cut of the neuration
