densely clotlied with squamose hair, — the terminal joint long, slender, 

 naked, erect {sWjhthj curved haclacard), rising considerciUg above head, 

 and suddenly and sharply acuminate at tip. Thorax moderately robust. 

 Abdomen as long as, or rather longer than, inner margin of hind-wings. 



Plotz (loc. cit.) refers seventy-one species to Apavstus, and among 

 them seventeen African forms, of which I have been able to examine 

 only two, viz., Notlius, Fab., from West Africa, and Philander, Hopff., 

 from the East and South-East. The former is the type of Butler's 

 genus Ceratrichia,^ and appears to be widely different from Ap)austus 

 ( = Ancyloxypha, Feld.), alike in its very long scarcely hooked antenna?, 

 short terminal joint of palpi, comparatively slender body, and rounded 

 hind-wings. The type of Ancyloxypha, is stated by Felder to be the 

 North- American A^nmifor, Fab., and the few species that he describes 

 are from Tropical South America. 



The very remarkable structure of the terminal joint of the palpi at 

 once distinguishes the members of this genus. I referred to it in 

 describing " one of the three now known South-African species — 

 Machenii, Trim. — as a doubtful member of the genus Famphila. An 

 approach to this character is exhibited by the European species of 

 Thymclicus. The South- African species are all blackish above, and are 

 more or less white on the under side of the hind-wings ; MacJccnii is 

 the smallest, and the ^ has no white spots above, but a white edging 

 and fringe to part of the hind-wings ; Philander has large spots, some 

 transparent and some opaque-white ; and Producta has all the spots 

 transparent, except one opaque-white spot in the fore-wings. The abdo- 

 men in Maclccnii is tipped, and in Fhilandcr belted with white above. 



These species are in South Africa only found on the south-east 

 coast, but Mackcnii (which is not uncommon at Natal) is recorded also 

 from Angola ; and Philander (which has occurred at Delagoa Bay) was 

 originally discovered at Querimba, and has also been noted from Angola. 

 Producta is only known to me by three specimens from Delagoa Bay 

 and one from Kimberley.
