yellow; while in the hindwings the pale area is of a clear 
ochrey-yellow (as in E. mima) but radiates strongly out¬ 
wardly, more especially along the inner-marginal border. 
The figures (uncoloured) of the larva and pupa of 
E. dubia, var. cerberus, Auriv., from Camaroon, published 
by Aurivillius (Ent. Tidskr., 1894, t 4, ff 4, 4a, and 4b) 
are smaller than the full-grown specimens of those of 
E. mima and E. waJdbergi that I have received from 
Mr. Millar, but they and the brief description (p. 282) 
agree pretty fairly with the specimens in question. As, 
however, the account of arrangement of the larval spines 
(which the author shows to be singularly identical with 
that exhibited by the larva of Salamis anacardii, L.) is 
not quite complete enough for comparison, I will add 
here what I have found to be the spinous armature both 
in E. %oahlbergi-mima and in E. dece'ptor larvae. Head 
with a pair of two long, stout, rather clavate and expanded 
(more distinctly so in dece'ptor'), divergent horns on vertex; 
these horns are moderately spinulose and also sparsely 
bristly, and bear three or four spinules at the tip. The 
first thoracic segment bears dorsally, one on each side of 
median line, two very short slender processes, each ter¬ 
minating in a long fine bristle, and also four rather short 
rigid spines finely spinulose throughout and tapering to a 
sharp point—two (upper and lower) on each side; and the 
second and third thoracic segments each bear in addition 
(in place of the slender processes on the first segment) a 
pair of longer dorsal spinulose spines. The abdominal 
segments each bear an additional acute similar spine on 
median dorsal line, making seven in all on each segment, 
except the last, which—more or less injured in the inflated 
dried specimens—appears to bear only five, but has the 
medio-dorsal spine placed far forward of the rest, close to 
the front edge of the segment (as Aurivillius mentions in 
his description of the Salamis anacardii larva). Besides 
the conspicuous spines above-named, there are on each 
segment quite low down, at base of legs and pro-legs 
where these occur, two very short blunt spinulose spines, 
one in advance of the other, both pointing downward. 
The colour of the larva in final moult is velvety-black; 
each segment bears anteriorly a narrow elevated or 
thickened pale-yellowish transverse band or half-ring, 
from which .spring the from four to seven brownish-yellow 
spines. The head, legs, and pro-legs are all brownish-
