Genus 4. Lophostethus, 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 veiy short pointed terminal joint ; tibise 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. 



Lophostethus demolinii. 



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



Smerinthm dumolinii (sic), "Walker, Lep. Het. viii. p. 250. no. 12 (1856) ; Pelder, Reise der Not., 

 Lep. iv. tab. 83. fig. 2 (Nov. 1874). 



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



Mr. Walker quotes Guerin'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.
