MR. A. G. BUTLER ON THE SPHINGIDZA. 585 
Genus 4. Lopnosternus, Butler. 
Euclea, Boisduval, Sp. Gén. Lép. 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 ; tibice 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 £. 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. 
LoPHOsTETHUS DEMOLINII. 
Sphinx demolinti, Angas, Kaffirs Illustrated, pl. xxx. fig. 11 (1849). 
Smerinthus dumolinii (sic), Walker, Lep. Het. viii. p. 250. no. 12 (1856) ; Felder, Reise der Noy., 
Lep. iv. tab. 82. fig. 2 (Nov. 1874). 
3 3, Port Natal (Gueinzius). Type, B.M. 
Mr.Walker quotes Guérin’s ‘Iconographie’ 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. 
Genus 5. Spuinconmproprsis, Wallengren. 
Sphingonepiopsis, Wallengren, Ofvers. Kongl. Vetensk.-Akad. Férhandl. 1858, p. 138.

Vetensk.-Akad. Handl. y. p. 19. no. 1 (1866). 
Interior of East Caffraria (Wahlberg). 
I have not seen any examples of this curious little Smerinthine Sphingid.

1. LANGA ZENZEROIDES.
