1910.] FROM NORTHERN RHODESIA. 43 



one female on the Lualaba river, iv., and one male on the Lubudi 

 river, x. In 1908 I took a second male on the Kalungwisi 

 river, N.E. Rhodesia, ix. The male, which is apparently hitherto 

 unknown, differs from the female in its smaller size and less 

 rounded primaries. It has the subapical band narrower, and 

 yellow instead of creamy white. On the under surface the black 

 apical suffusion extends more than halfway down the cell to the 

 base of the costa. All the under-sm-face markings of both sexes 

 in the Katanga specimens are heavier than those of the type from 

 Nigeria. I took this species only in dense forest. It looks exactly 

 like an Acrcea on the wing, but like 31. marshalli settles on tree- 

 trunks, which at once " gives it away" to the entomologist. 



Teriomtma hildegarda Kirby. 



This species is common in woodland over a wide area from the 

 beginning of the rains until April or May, being scarcer the last 

 two months. I am rather inclined to think that it may prove to be 

 the wet-season form of the next species. 



Teriomima aslauga Trim. 



This species, of which T . pallida Trim, is perhaps a very dry 

 phase, occurs over a wide area, and is especially common in the 

 Luangwa valley. It is on the wing from the end of March to 

 August and I have taken one individual as late as November. 



Larinopoda tera Hew. 



Represented by a single specimen from the Lubudi river, x. 



LlPTENA HOMEYERI Dewitz. 



This species occurs locally in the Luangwa valley in March only. 

 In Katanga I found it abundant from December to June. It 

 always frequents woodland, and except for its somewhat deeper 

 colour is hardly distinguishable from a Terias on the wing. 



ASLAUGA PURPURASCENS Holl. 



I took two specimens of this insect on the Alala plateau north- 

 east of Broken Hill, xi., and one other in the Ohambezi valley, v. 

 A. marshalli Butler appears to be a very doubtfully distinct species, 

 as Trimen* has already pointed out. 



Lachnocnema bibulus Fabr. 



This species is ubiquitous and on the wing at all seasons. 



Lachnocnema durbani Trim. 



This species also occurs everywhere but is less common than the 

 foregoing. 



PiLODETjDORix c<erul,ea H. H. Druce. 



I took this species sparingly in a great variety of localities from
