11 ad 1 latiori, minus crebre minus fortiter punctulato 
prosterno medio haud carinato; corpore subtus magis 
subtiliter punctulato ; cetera ut C. ocularis. Long., 6—7 1. ; 
lat., 22—32 1. 
Apart from the characters mentioned above, the description of 
C. ocularis (P. L.S., N.S.W., 1893, p. 79), applies to this species, 
which stands beside it in my tabulation of the species of 
Chalcopterus (loc. cit., p. 64). It differs from all the hitherto 
described Australian Chalcopteri except ocularis in its (all but 
contiguous) eyes, and from ocularis by its different colouring, 
much more slender antenne, less tranverse prothorax, &c. 
W. Australia ; sent to me by Mr. French. 
_ ©. zonatus, sp. nov. C. Mercurio, Blackb., affinis ; coloribus

nitido, distincte sat crebre punctulato; elytrorum striis

Except in respect of the characters mentioned above the 
description of C. Merceurius (P. L.S., N.S,W., 1892, p. 450), 
may be read as the description of this insect. In my tabulation 
of the species of Chalcopterus (loc. cit., 1893, pp. 56, &e.), the 
present species would stand beside mzmus, Blackb., under JJ, and 
may be distinguished from it as indicated under the next species 
(C. costatus). 
N. Queensland (Mr. Koebele). 
C. costatus, sp. nov. Elongatus, subparallelus ; modice nitidus ; 
niger, elytris obsure cyaneis latera versus nonnihil aureo- 
micantibus ; capite sat equaliter crebre minus subtiliter 
punctulato ; oculis antennarum articuli basalis longitudine 
inter se remotis ; sulcis ocularibus nullis; antennis quam 
corporis dimidium subbrevioribus modice robustis, apicem 
versus haud incrassatis, articulo 3° quam 1™ 2" que con- 
juncti vix longiori quam 4"° 5"* que conjuncti parum breviori, 
articulis apicalibus quam precedentes haud_brevioribus ; 
prothorace quam longiori ut 15 ad 1 (postice quam antice ut 
12 ad 1) latiori, subtiliter sat crebre punctulato, antice fere
