34 Mil. S. A. NEAVE ON BUTTERFLIES [Jan. 18, 



characterised by being markedly more denticulate and projecting 

 toward outer margin in areas 5 and 4. 



Underside.— A dark patch invariably obscures the submarginal 

 white markings of the outer margin of the primaries in the lower 

 half of area 4 and the whole of area 3. A tendency to this latter 

 character also appears in some individuals in the Hope Collection 

 from the West Coast, which appear to be indistinguishable from 

 typical agatha. Whether they are really so seems to be a point 

 which will not be cleared up until some attempt is made to unravel 

 the confusion in which this genus now is. 



The other markings of jordani much resemble those of agatha. 

 The margins, especially of the secondaries, are however somewhat 

 more markedly denticulate than those of agatha. 



Type 6 in the British Museum : Chishi Island, Lake Bangweolo, 

 25.vi.08. Type § in the British Museum : Kambove, Katanga, 

 I7.ii.07. 



Cotypes in the Hope Coll., Oxford. 



Described from over 50 specimens. 



I am greatly indebted to Dr. Karl Jordan of the Zoological 

 Museum, Tring, for his assistance with this puzzling species, and 

 I have the honour of dedicating it to him. He has been so kind 

 as to examine the genitalia of the species and of typical agatha 

 from the same place, and he pronounces them to be quite distinct. 



I had long been convinced from my field experience that 

 jordani represented a distinct species. Whilst I found agatha 

 ubiquitous in Northern Rhodesia, etc., jordani was distinctly local. 

 It usually frequents rather hot dry localities, such as river-valleys 

 where there are thickets or dense bush. I originally captured a 

 pair in copidci on the Alala plateau, north-east of Broken Hill, xi. 

 In Katanga I took it sparingly, chiefly in river- valleys, ii.-x., 

 and subsequently found it abundant in the thickets on the shores 

 and islands of Lake Bangweolo. It has a more restless, active, 

 and less floating flight than agatha. 



Neptis melicerta Drury.

 A forest species.

Four specimens from the Lualaba river, iv. and v., 1907. A 

 forest species. 



Pseudacr^ea lucretia tarquinia Trim.
