basal patch, abruptly ending a little before extremity of discoidal cell ; 
disco-cellular spot often much larger than in ordinary specimens ; spots 
in hind-marginal band conspicuous for their luhiteness. Hind-wing : the 
whole or greater part suffused luith grey ; disco-cellular spot whitish, 
centred with yellowish ; hind-marginal spots in band whitish, variable 
in distinctness. Under side. — Fore-wing: basal portion, costa to beyond 
middle, and all but apical portion of hind-marginal band, bluish grey ; 
apical portion of band dull greenish-yellow or yellowish-green ; black 
spots as in ordinary specimens. Hind-wing : marked as usual, but of 
the same dull mixture of yellow and green as apical colouring of fore- 
wing. Antenna3, legs, margins, and fringes pink^ as in the common 
examples."^ 
Larva. — Attenuated posteriorly ; slightly and thinly pubescent. 
Yellowish-green, closely irrorated with darker atoms. Along centre of 
back, from head to tail, a dark-green streak ; on each side of back 
an ill-defined yellow streak, shading above into the pale-green. On 
each side, touching yellow streak, a broad dark-green band, edged 
inferiorly by a conspicuous pure-white or yellowish-white narrow stripe 
above spiracles. Head granulated, clothed with very short pale hairs. 
Pupa. — Attached invariably head uppermost. Pale-green, semi- 
transparent, darker anteriorly. Prominences of head and back of thorax 
rather obtuse ; outline of wings projecting in a convex ridge below 
breast. A dark-green dorsal line. Median lateral line of frontal pro- 
minences marked with a black streak inferiorly edged with greenish- 
yellow ; inner- marginal edge of wing-cases also defined with blackish. 
On each side of abdomen a yellowish-white stripe ; below this, touching 
hind-margin of wing-covers, a short abruptly-ending black streak. 
The larvse were found in May, feeding on Vicia sativa (lucerne). 
The pupa state continued from eighteen to twenty-three days, but this 
was in the beginning of winter. 
Except in size and in the width of the hind-marginal border 
(especially in the fore-wing), the ^ Elcdra varies very little ; but the 
$ exhibits many variations in tint of ground-colour and development of 
the basal blackish space in the fore-wing, leading in the direction 
of the white form above described, which is figured by Cramer as 
Pcdmno. 
Very small examples of both sexes are often met with ; a ^ in my 
own collection expands only 1 in. 5^ lin., and a ^ in the South- African 
Museum only i in. 4 lin. 
The pale form of though not rare, is very much scarcer than the 
orange-yellow one. 
Electra is nearly related to the well-known European C. Edtcsa, 
^ Mr. Moschler {Verli. K.K. Zool.-Bot. Gescllsch. Wien, 1883, p. 279) states that I in 
error described this form of the ? as Ilyale, L. That I did not do so will be evident on 
reference to my Rliop. Afr. Ausf., i. p. 72, where the pale " Var. ? " of Electra is described, 
and p, 74^ where the true Ilyale is fully described in reference to some reputed South-African 
specimens.
