to upper discoidal nervule, then convexly suberect to upper 
median nervule, after which it is outwardly elongated, and 
terminates at about the lower median nervule; inwardly it 
is excavated at the discocellular nervules, before which and in 
the cell it possesses an extension of two irregular spots. Poste- 
rior wings sulphureous, with a broad outer black margin. 
Wings beneath sulphureous; anterior wings faintly showing 
the orange-coloured fascia above, sparingly speckled with 
fuscous in upper portion of cell and along the costal and outer 
margins (most broadly so at apex), and with a fuscous spot 
at posterior angle; posterior wings also sparingly speckled 
with fuscous. Body and legs more or less concolorous with 
wings. 
Exp. wing 56 millim. 
Hab. Malay peninsula, Sungei Ujong (Godfery). 
This species is allied to Z. aneaxtbia, Hiibn., and L. latifas- 
ctatus, Butl.; from both it differs by the narrower black 
marginal border to the posterior wings, and on the anterior 
wings by the greater extension of the black area across the 
cell, and also from the first by the paler-coloured orange 
fascia, which is also more dilated beneath the upper median 
nervule. 
Papilio caunus, Westw., race egialus. 
&. Closely allied to P. caunus, but differing in having the 
white markings with their pale bluish terminations on the 
upper surface of the posterior wings smaller and more con- 
fined to the basal half. 
Hab. Singapore (Godfery). 
Exp. of wings 94 millim. 
The interest attaching to this local race of P. caunus, and 
on account of which it is here described, is owing to its being 
a mimic of Huplea diocletianus, which is also the local race or 
form in the Malay peninsula of 1. rhadamanthus. We thus 
see this mimicking Papilio modified in the same manner as 
its mimicked species ; and if . diocletianus is recognized as a 
distinct species, this race, if found to be constant, will have 
(in an artificial and systematic sense only) to be recorded in 
the same way. ‘he Bornean form of this Papilio will also 
probably be found to mimic the race or species Huplea 
Lower.
