274 Mr. H. Eltringham's Monograpli of the 



scales in area lb. H.-w. basal black of rather less extent, liind- 

 marginal border black and rather broader. Underside. H.-w. 

 basal area more chestnut brown, marginal border darker and 

 inclined to reddish at its inner edge. 



The larva of A. iieneleos (PL VI, f. 4) from Oni, near 

 Lagos, may be described as follows :— 



Ground-colour dark brown with transverse striae of a darker 

 lint, bordered with yellow. Lateral line and legs yellow. 

 Head bright chestnut. In the actual larva all the spines are 

 black, but according to Mr. Lainborn's notes the subUiteral spines 

 are yellowish. There may possibly be some variation in this 

 respect. 



True perceleos seems to occur from S. Leone through 

 Lagos and as far as Fernando Po, producing the aberrant 

 forms of ^ above described. From Fernan Vaz and right 

 across the Congo State we find the development, at first 

 somewhat irregular, of the dark-coloured underside of the 

 h.-w. with its central ochreous band. On the Kassai R. 

 forms are found which vary between |9e%e/co5 and jJclasgius, 

 and thence the latter form is predominant. It is very 

 common at Entebbe, whence its distribution extends north- 

 eastwards into Abyssinia, where it is represented by the 

 form gelonica.

1^. Expanse 68 mm. F.-w. sepia black. Cell, basal j)ortions 

 of (i, 5, 4, 3, 2, and nearly all lb, rather thinly sealed and partially 

 transparent. A slight submarginal powdering of whitish scales 

 in lb. H.-w with a dark sepia grey basal suffusion extending 

 slightly beyond origin of nervule 2, and outwardly approximately 

 determined by a line drawn from middle of costa to middle of 

 inner margin. Discal area deep orange red (probably rosy 

 red when alive), A well-defined brown-black hind- marginal 

 border about 2 mm. wide, its inner edge slightly edentate 

 on the nervules. Black spots as beneath, but obscured by basal 

 suffusion. 



Underside. Costa, apical area and hind margin dusky 

 ochreous, striated by the nervules and rays which are broadly 

 powdered with dark brown. The ochreous marginal border
