22 MR. S. A. NEAVE ON BUTTERFLIES [Jan. IS, 



Hill district, N.W. Rhodesia-, ix. and x. 1905, and in Katanga 

 I found it plentiful in the Lualaba valley, x. and xi 1907. Some 

 of the wet-season females from the last-named locality are nearly 

 black. It is a somewhat local species, frequenting nevertheless 

 rather varied country, as I have taken it both in woodland and 

 open grassy plains. I also captured a few individuals in the lower 

 Chambezi valley, N.E. Rhodesia, x. 1908. 



ACRJEA LEUCOPYGA. 



Acrcea leucopyga Auriv. Ent. Tidskr. 1904, p. 92, fig. 32. 



I took this species in the Luangwa valley, on both my expedi- 

 tions, from January to March. The specimens are consequently 

 all wet-season ones, and differ a little from Prof. Aurivillius' figure 

 of the type which appears to be a dry-season specimen. My 

 specimens are smaller and have heavy black margins of varying 

 width 'to the secondaries. The females also, as in so many other 

 wet-season Acraeina? in this part of Africa, are very dull-coloured 

 and have a varying amount of dusky suffusion over the base of 

 both wings. The females further have the whole of the abdomen 

 black with white lateral spots and lack the white apical segments 

 described by Aurivillius. This character is, however, well marked 

 in the males. 



I took this species sparingly, ten males and eight females, in 

 the Luangwa valley only. It has the same low flight as onca/a 

 Hopff. and somewhat resembles it On the wing. 



Acrcea intermedia, 



A. intermedia Wichgraf, B. E. Z. liii. 1908, p. 241, pi. 6. figs. 3, 4. 



I took three males of this recently described species on the 

 Lualaba river, iv. and v, 1907, and subsequently a very dry female 

 on the Kalungwisi river, ix. 1908. This specimen has all the 

 markings much reduced, and a mere trace of the subapical white 

 is figured in Wichgraf's specimen,

 figs. 1, 2, but with a black, white-barred apex to primary. The 

 discal spots of 1 & and 2 of primary, in both species, make a 

 line perpendicular to the hind margin, bringing them into group

 A. caldarena Hew. 



Upperside. — Primary. Apical portion of wing suffused with 

 black, deep black at tip, becoming a dark greyish toward discal 

 area. This dark suffusion covers rather more than the distal 

 half of the cell on the costal margin and on the outer margin 

 becomes reduced to a narrow dark line as it approaches posterior- 

 angle. Remainder of wing of a bright salmon-orange, scattered 

 at base with some dusky scales and bears following black spots : 

 a large spot within cell ; a discocellular ; beyond extremity of cell
