176 Mr. H. Eltringham's MonograiJli of the 



Some fine examples of the ^ oncaea taken by Neave 

 on Chirui I., L. Bangweolo, have tlie f.-w. dull rosy red, 

 and the space between the discal spots and the apical 

 black is grey. The inner edge of the apical black is much 

 suffused and broken up by submarginal orange spots each 

 of which is divided by a black ray. The h.-w. is bright 

 red witli a rosy tinge, and bears the usual black spots. 

 The h.-w. underside at base and inner margin is deep 

 rose pink. 



Suffert describes under the name caoncius (/. c.) a form 

 in which the f.-w. apical black is no wider than the 

 marginal black. 



5 . Expanse 48-64 mm. Extremely variable. Whilst in a long 

 series all kinds of intermediates may be found, the following may 

 be specially noted : — 



(1) Dry season, F.-w. base to discal row of spots reddish chocolate. 



Beyond the spots a white band in 10, 9, 6, 5, 4, and 3, 

 about 4 mm. wide. Between the outer edge of this and 

 the apical black, dusky orange. H.-w. reddish chocolate 

 with a pink patch beyond cell in 4, 3, 2, and Ic. Spots, 

 etc., as in (J. 



Underside. F.-w. paler and duller. White area replaced by 

 creamy yellow, apex pale ochreous with orange internervular 

 marks. 



H.-w. whitish with rose pink marks beyond discal spots and 

 at base and inner margin . . . = f . ohsciira, Suffert. 



(2) Dry season. Similar to (1) but without the white patch in 



f.-w. . . . . . . = f . defaseiata, Suffert. 



(3) Wet season. Resembles (^ but the wings are greyish black, 



and f.-w. has a white patch as in (1). H.-w. marginal 

 black, broader than in (J and inner edge suffused. Little 

 or no basal black suffusion. Underside similar but paler. 

 This form agrees with figure of Hoppfer's type. 



(4) Wet season. Resembles (3) but the nervures of h.-w. dusted 



with white . . . . = f. alhoradiata, Suffert. 



(5) Wet season. Resembles (3) but h.-w. with a large white median 



patch . . . . . . = f . vwdesta, Suffert. 



<(6) Resembles ^ but wings are dull ochreous grey. No white 



markings. Underside similar but h.-w. dark ochreous. 



In all the 5 forms the abdomen is black above with whitish 



or yellowish lateral spots. 

 f. liacea. 



This form was described by Suffert as a subspecies of caecilia, 

 but having examined the types I find it belongs to the present
