30 MR. S. A. NEAVE ON BUTTERFLIES [Jan. 18, 



Precis cuama Hew. 



Precis trimeni Butler. 



Common in woodland in the Zambezi and Luangwa valleys side 

 by side with the preceding. This species appears not to be present 

 in Katanga or the high plateau country of N.E. Rhodesia west of 

 the Mchinga escarpment, additional evidence that it is probably 

 a distinct species from antilope. 



Precis ceryne Boisd. 



Precis tukuoa Wallengr. 



A common species over all the high plateau wherever there is 

 sufficiently open country. It is more addicted to open grassy 

 plains than any other species of Precis with which I am acquainted 

 except sophia Fabr. 



Precis pelarga Fabr. 



This is a common woodland species at all seasons. Specimens 

 from the Luangwa valley belong to f. actia, whilst all those from 

 the high plateau country of N.E. Bliodesia and throughout 

 Katanga are intermediate between that form and typical pelarga, 

 the males of the dry specimens, at least, being dimorphic. 



Precis tugela Trim. 



Not rare in well-wooded localities throughout the country. 

 Particularly common in the thickets on the islands of Lake 

 Bangweolo. 



Precis archesia Oram. 



Precis pelasgis Godt. 



This species occurs everywhere but is nowhere very common, 

 the wet-season form pelasgis being distinctly scarce in my ex- 

 perience. Dry-season specimens from Katanga approximate to 

 the form staudingeri Dewitz. It is a woodland species, more 

 common in hilly country than anywhere else. 



Precis terea elgiva Hew. 



A common insect in well-wooded localities throughout the high 

 plateau country, including Katanga. Not met with in the 

 Luangwa valley. 



Precis natalica Feld. 

 Ubiquitous at all seasons. 



Precis artaxia Hew. 



Precis nachtigalli Dewitz. 



Ubiquitous in woodland. The wet-season form, nachtigalli 

 Dewitz, is scarce and usually on the wing only from mid- 

 December to mid- January, but I have taken an occasional very 

 worn specimen as late as the beginning of March.
