CHRYSOMELIDSA. 395 
CHALCOMELA CUPREOSPLENDENS, N0.Sp. 
Head (including clypeus), prothorax (the basal third at 
sides, and fourth in middle, and the apex narrowly, purplish- 
blue), base sides, and epipleure of elytra, prosternum, metas- 
ternum (except margins), middle of basal segment of ab- 
domen, and part of ‘femora, of a fiery copper; elsewhere 
purple ; -the antenne blackish, with the basal joints partly 
diluted with red. 
Head with a few minute punctures’; clypeus finely punc- 
tate, separated from the face by a deep groove, from the 
middle of which a feebly impressed line extends backwards 
to the base. Prothorar minutely punctate, the sides with 
moderately large but not very dense punctures. Llytra 
with regular series of not very small punctures, beccming 
small towards apex ; the interstices feebly separately convex 
in places, and with sparse minute punctures. Length 53, 
width 4mm. 
Hab.—Thursday Island (Macleay Museum). 
The shape is that of ezimza and msignis, but the elytra are 
almost entirely purple; the coppery part commences un each 
side of the scutellum, and is continued irregularly round the 
sides to apex, being widest on, and narrowest on each side 
of. the shoulders. 
CHALCOMELA VIRIDIMICANS, D.sp. 
Upper and under surface of a brilliant green, with a slight 
coppery gloss, and in certain lights appearing purplish ; 
legs, antenne, and muzzle reddish. 
Head with irregular and fine punctures, becoming denser 
and larger at base; clypeus with distinct punctures, its 
suture not deeply impressed but distinct; from its middle a 
feebly impressed line extends backwards to the base. Pro- 
thorax with small and almost regularly distributed punc- 
tures; a few larger ones at extreme base, but not at sides. 
Elytra with series of small punctures, becoming very in- 
distinct towards apex. Under-surface with a semi-circular 
row of large punctures behind each of the four posterior 
coxe. Length 8, width 64mm. 
Hab.—N.Q.: Cairns (Macleay Museum). 
The shape is that of dludens. Of two specimens under 
examination, one has a shallow fovea on each side of the 
prothorax, whilst the other has two small fovee on each 
side, the outer one of which is more distant from the side 
than in the other, so that they are probably all accidental.
