6'6 MR. S. A. WEAVE OX BUTTERFLIES [Jan. IB, 



Teracolus ducissa Dognin. 



I took this handsome Teracolus chiefly in hot dry places. 

 Strange to say I only met with females, of which four were taken 

 in the Kambove district, iv.-viii., and five others in the neigh- 

 bourhood of Lake Bangweolo, vii. 



Eronia cleodora Hiibn. 



I found this a rare insect. I captured one individual at 

 Kambove, iv., and saw one or two others. A second specimen 

 was taken in the neighbourhood of Lake Bangweolo, vi. 



Eronia leda Boisd. 



A common insect in the Luangwa valley but rather uncommon 

 in the high plateau and in Katanga. It flies usually near the 

 ground and is very active on the wing. 



Eronia argia Fabr. 



This species occurs all over the country in patches of forest, 

 particularly in the neighbourhood of streams. It flies very high 

 with a rather sailing flight and is not easily captured in 

 quantities. 



Eronia thalassina Boisd. 



This species occurs in the same localities as the foregoing and 

 has much the same habits, the males being much more in evidence 

 than the females. 



Eronia buqueti Boisd. 



This would seem to be a coast species, as I took it only in the 

 neighbourhood of Tete on the lower Zambezi. It has more the 

 habits of E. leda than of the two preceding species. 



Oatopsilia florella Fabr. 



Always abundant. Occasionally seen in enormous numbers. 

 I once saw several "patches" of this species, several square yards 

 in extent, on damp sand in a tributary of the Luangwa river, xi. 

 They seemed to be almost entirely males. 



Terias senegalensis Boisd. 



Ubiquitous, as also are the two succeeding species. 



Terias desjardinsi Boisd. 



Terias brigitta Cram. 



In Katanga this is rather scarcer than the last-named. 



Colias electo L. 



." Only taken in the Alala plateau, Broken Hill district, and then 

 sparingly. An open country species.
