‘bears no granules except those in the series and a very small 
number placed more or less out of line with them, and the 
‘granules are emphatically not black. Among its allies with rows 
of granules, H. subseriatus is distinguished by the presence of a 
short longitudinal strongly elevated carina on the prothorax in 
front of the basal horn from all except princeps, Macl. (1 Hope) 
and elongatus, Blackb. 
W. Australia. 
H., brevicostatus, Blackb. This species must be regarded as 
-connecting Sir W. Macleay’s “first group” with his “third 
group,” resembling the latter in the comparative narrowness of 
the overlapping front processes of its prothorax and in the 
rudimentary subsutural costz of its elytra being a little more 
defined and elongated than in the other species of the first group 
though extremely different from the well-defined subsutural cost 
-of the third group. It agrees with the first group in the space 
between the subsutural quasi-costie not being flattened. 
CHALCOPTERUS. 
C. puer, sp, nov. C. difficili, Blackb., affinis; oculis inter se 
magis approximatis (interspatio quam antennarum articuli 
basalis longitudo subangustiori); prothorace magis crebre 
punctulato, margine laterali (a latere viso) multo minus 
fortiter arcuato; elytrorum puncturis seriatis postice 
obsoletis, interstitiis subtilissime punctulatis; metasterno 
et episternis minus subtiliter punctulatis; tarsorum posti- 
corum articulo basali quam ceteri conjuncti haud breviori ; 
cetera ut C. difficilis, Blackb. Long., 6 1.; lat., 3 1. 
It seems hardly necessary to repeat the numerous characters 
common to this species and C. difficilis (which are elaborated in 
Pr. L.S., N.S.W., 1892, pp. 426-7); the description of C. difficilis 
may be read as applying to C. pwer in all respects except those 
specified above. It should, however, be remembered that 
where C. difficilis is compared with C. cupripennis, the insect 
referred to under the latter name is cupripennis, Germ. and 
Blessig, which has been shown (P. L.S., N.S.W., 1893, p. 70) 
not to be identical with C. cupripennis, Hope, but to be C. affinis, 
Blessig. {= C. (Amarygmus) Howitti, Pasc. | 
In my tabulation of the species of Chalcopterus (P. L.S., 
N.S.W., 1893, pp. 56, &c.) C. puer would fall on p. 59 besides 
C. vigilans, Blackb., and proximus, Blackb., though not much 
resembling them, between which the seriate punctures of its 
-elytra are somewhat intermediate ; it, however, differs from both 
inter alia in the very evidently wider interval between its eyes, 
-and its considerably more nitid elytra.
