MR. A. G. BUTLER ON THE SPHINGIBvE. 585 



Genus 4. Lophostetdus, Butler. 

 Euclea, Boisduval, Sp. Gen. Lep. i. p. 14 (1875). Name preoccupied. 



Form of wings as in Triptogon ; metathorax and base of abdomen tufted with erect 

 scales ; collar wide ; palpi small, with very short pointed terminal joint ; tibia? of front 

 pair of legs terminating externally in a formidable hooked claw, of second pair in two 

 claws, external and internal, of third pair in,three unequal internal spines ; basal half 

 of wings below densely clothed with long hair-scales. 



Type E. demolinii. 



I know of no other moth armed with such powerful weapons as this genus. It is 

 impossible to guess their use, unless they are intended for scratching. 



LOPHOSTETIIUS DEMOLINII. 



Sphinx demolinii, Angas, Kaffirs Illustrated, pi. xxx. fig. 11 (1849). 



Smerinthw dumolinii (sic), Walker, Lep. Het. viii. p. 250. no. 12 (1856) j Pelder, Reise der Nov., 

 Lep. iv. tab. 82. fig. 2 (Nov. 1874). 



(j ? , Port Natal (Gueinzius). Type, B.M. 



Mr. Walker quotes Guerin's ' lconographie ' for this species, but gives no reference to 

 page or plate. I have referred to the book, but cannot find it ; and Angas states his 

 belief that it is a new species, which renders it most probable that he was the first to 

 publish it.

I have not seen any examples of this curious little Smerinthine Sphingid.
