Possibly the male of G. Batschii, but differing from the 

 figure in form, and considerably smaller. 



Other Sphingidae received from Mr. Kingdon are : — A mbulyx 

 Coquerilii <S , Boisd. ; Choerocampa gracilis, Butl. (a South- 

 African species) ; Protoparce lingens $ , Butl. j and Diludia 

 cJiromapteris, Butl. Of the last-mentioned species (hitherto 

 unique, so far as I am aware, in the Museum collection) there 

 was a very fair series, exhibiting slight variations in the 

 intensity of the coloration, but not in any of the markings. I 

 consider this rather important evidence in favour of its dis- 

 tinctness from the allied D.jasmini, Boisd., since that species 

 is described as having " whitish grey upper wings and ash- 

 coloured stigma," no mention also being made of the parallel 

 discal series of whitish spots common to D. cliromapteris ; 

 the lower wings moreover are said to be " black, with the 

 base broadly of a beautiful orange-yellow, and the anal angle 

 marked by a little patch of ashy grey; " in D. cliromapteris 

 they are greyish brown, with the basal half bright ochreous, 

 with two transverse central blackish bands, the inner one 

 quite black, the outer one dentate and dividing a series of
