1910.] FROM NORTHERN RHODESIA. 51 



anal lobe on inner marginal side more strongly black. A well- 

 marked line of long dark hairs between veins 1 b and 2 (very 

 slightly developed in female). This seems to represent the 

 rudiment of the primitive 3rd interna] nervure. 



Palpi pale yellow ; thorax and base of abdomen above covered 

 with pale blue hairs, remainder of abdomen pale yellow, outlined 

 on edge of segments with reddish chocolate. 



Length of primary 18 mm. 



The female differs in having more rounded wings ; in the 

 primaries the basal white cell-band is more extensive, and the 

 second and third orange spots near outer margin are more ex- 

 tensive and confluent, forming an irregular submarginal band. 



T}'pe <$ in the British Museum : upper Kalungwisi valley, 

 9.ix.08. Type £ in the Hope Coll., Oxford : Lofu river, 8.viii.09. 

 Described from 18 males, 5 females. 



This species occurred sparingly from the Chambezi valley to 

 near Lake Tanganyika, iv.-ix. 



Spindasis mozambica Bert. 



This is a common species at all seasons. It seems to occur 

 everywhere. 



Spindasis homeyeri Dewitz. 



This is a very common species throughout the high plateau 

 country. The dry-season specimens of this species have the 

 markings of the underside reduced and the ground-colour much 

 darker. S. kallimon H. H. Druce * appears to be figured from 

 a.n extreme wet-season specimen of this species. 



Spindasis crustaria Holl. 



Represented by a single male from the Alala plateau, which is 

 somewhat paler above, having a, marked basal wash of pale blue 

 and less heavily marked below than in specimens from the 

 tropical West Coast, and possibly represents a new race. 



Spindasis sp. near aderna Plbtz. 



Two females from the upper Kafue river allied to the above 

 species, but in absence of males I hesitate to describe them. 

 They are larger insects, altogether paler than the females of 

 aderna, the whole discal area and primaries and whole of 

 secondaries being uniform orange without any dark markings. 



Zeritis sorhageni Dewitz. 



I captured three individuals, two males and one female, of this 

 rare species near Kambove, Katanga, iii. I saw, but did not 

 take, another on an open plain on the upper Lufupa river, x. 

 It frequents open country and flies, not very strongly, near the 

 ground.
