1910.] FROM NORTHERN RHODESIA. 35 



Repi-esented in the collection by a single specimen from the 

 mid-Luangwa valley, viii. 



Pseud acr^a poggei Deivitz. 



A by no means rare species throughout Katanga and the 

 northern portion of the plateau country of N.E. Rhodesia. It is 

 on the wing throughout the year, but is uncommon during the 

 dry season, and then seems to confine itself strictly to dense 

 forest. In the wet season, when much more abundant, it haunts 

 the woodland country and clearings in the forest. On these 

 occasions it may sometimes be seen side by side with its model, 

 Limnas chrysippus, and the resemblance both of flight and 

 colouring is so exact that it is quite impossible to distinguish 

 them on the wing. 



Pseudacr^ea trimeni Butler. 



This species occurs rarely in Katanga, and I did not meet with 

 it elsewhere. 



PSEUDACR^A DOLOMENA Hew., ? f . RUBROBASALIS Auriv. 



A single specimen of what is very near to this form of the very 

 variable dolomena was captured in a patch of dense forest between 

 the Lubudi and Lufupa rivers, Western Katanga, x. 



PSEUDAOR.EA SEMIRE Cram. 



I captured two specimens of this species in dense forest on the 

 lower Kalungwisi river, ix. 



PSEUDONEPTIS 0O3NOBITA Fabl'. 



A forest species, not rare in suitable localities in the Lualaba 

 valley, but not met with elsewhere. It has a general resem- 

 blance to a Neptis when on the wing, but has a more active and 

 less floating flight. 



PSEUDARGYNNIS HEGEMONE Godt. 



This insect is common and widely distributed throughout the 

 more open plateau country, both of N.E. Rhodesia and Katanga. 

 It often may be taken at damp mud, and I once captured an 

 individual of this species amongst some 14 specimens of its model, 

 Atella phalanta, on such a spot. It is on the wing throughout the 

 year. 



Form nyassce Bartel* appears to be described from an extreme 

 dry-season specimen, and does not, I think, represent a local 

 race. 



Catuna crithea Drury. 



This species is common in patches of forest in Katanga and in 

 the Kalungwisi and Lofu valleys in N.E. Rhodesia. I have 

 never taken it out of dense forest. It has a somewhat weak
