middle, all this space hein,^ clothed with very dull purplish-red down ; hind-

 beneath darker. Antennae dull yellowish. Eyes faintly ringed with ochre- 

 yellow. Thorax above with two median and two posterior inconspicuous ochre- 

 yellow hairy tufts ; beneath with a well-marked prothoracic front edging, and 

 some less defined mesothoraeic and metathoracic hairy tufts, all ochre-yellow.

Allied to P. phijllis, E. & J.,* from Konakry Island, Los Islands, 

 West Africa, being quite similar in general character and shape of 

 wings, but very different in colouring, P. j^hyUis having the fore-wing 

 very pale reddish-brown, shaded with a deeper thit beyond middle, and 

 the hind-wing yellow, thickly spotted with rust-red, with the basal 

 ovate black subocellate marking almost devoid of any paler centre. P. 

 hourhei is also related to the still larger (exp. al. h\") P. stigmatica, 

 Mab., from the Congo, f which is coloured similarly to P.phyllis, but has 

 the under-side universally yellow, varied with generally dispersed ir- 

 regular and broken rust-red bands and spots. A third ally, kindly 

 brought to my notice by Sir G. Hampson, is P. piabiUs, Dist., a native 

 of the Transvaal, which I have not seen, but which, from Rothschild 

 and Jordan's description (I.e., p. 227) of the (^ type, differs greatly 

 from P. hourhei on the iipper-side in the yellow disc of the fore- wing 

 and the yellow hind- wing speckled with red, and on the under-side in 

 the universally yellow tint, varied with a red bar and spots in the fore- 

 wing and red speckles in the hind- wing. 



This fine Smerinthine was discovered at Etshowe, in Zululand, by 

 my friend Eear-Admiral Edmund Bourke, after whom I have the 

 pleasure of naming it. He writes : — "I took it at Etshowe on the 8th 

 April, 1909, in a bush road ; it was clinging to some low herbage, and 

 I do not think it had ever used its wings. I glanced round for others, 

 but was too busy vdth the butterflies to make a search." 



Admiral Bourke presented this unique example to Mr. A. D. 

 Millar, of Durban, who kindly forwarded it to me for determination.
