288 Mr. H. E^ltringham's Monograph of the 



I have not seen a 9 of this form, but judging from those 

 of the other forms it probably does not greatly differ from 

 the $. 



Suffert's diavina has in f.-w. a smaller subapical spot, and 

 larger spots in 2 and lb. It was taken at Victoria, Cameroon, 

 but similar examples are before me from N. Rhodesia. 



Aurivillius (/. c.) describes the larva and pupa as 

 follows : — 



Larva very like that of bojiasia, but more marked with red 

 brown above, and with paler and more interrupted longitudinal 

 streaks. Only the spines of segments 1, 2 and 11-13 are black, 

 the remainder being whitish. The head is blackish with a pale 

 anterior bifurcate middle line. 



Pupa pale with black markings, the five rows of spots of the 

 abdomen formed of separated subquadrate spots with pale 

 centres, the latter not raised. 



Examples of the larva (PI. VI, f. 13), taken by Mr. W. A. 

 Lamborn near Lagos are pale green with a few brownish dorsal 

 and dorsolateral marks on each segment. Lateral line pale 

 yellowish. On the first and last four segments the spines are 

 black. The remainder are yellowish. An anterior view of the 

 head shows it to be brownish with a black triangular mark 

 in the centre, on each side of which is a thick black line. 

 The food plant at Lagos is Lepistemon africannm, Oliv. {Con- 

 volvidaceae). 



Examples of accrata taken by Neave in the neighbour- 

 hood of L. Bangweolo vary very considerably and may 

 be of the acerata or vmidia form, the latter predomin- 

 ating whilst there are intermediates to tenella and 

 hrahmsi. 



The species has a wide distribution. The vinidia form 

 is predominant, true acerata appearing rather occasionally. 

 Both occur from Ashanti, through Togoland, Nigeria, 

 Cameroon, French Congo, Angola, Congo State to North 

 Rhodesia. In this region many intermediate forms are 

 found. In Nyassaland, German East Africa and British 

 East Africa, and extending into Abyssinia (Marmasa and 

 Alaballa) tlie tenella f. is predominant and might per- 

 haps be regarded as an eastern subspecies, though it is 

 scarcely sufficiently constant to be thus separated. The 

 local form hrahmsi is found in Cameroon (Bipindi) and 

 Nigeria (Kabba Town).
