elytra also are differently sculptured, the strize containing for 
the most part rounded and not very closely placed punctures, 
whereas in C. Championi the puncturation of the striz is caused 
by fine transverse keels connecting interstice with interstice.

Another large species allied to the preceding, from which it 
differs by its antenne somewhat more robust, its prothorax and 
head evidently more finely and closely punctulate, and by the 
sculpture of its elytra, the punctures of the striz being similar 
to those of C. Championi, but evidently smaller. In 
C. eremicola the diameter of most of the punctures in the striz 
is greater than the width of an interstice between the strie ; in 
this species much less. This species differs from C. Championr 
in its prothorax shaped like that of C. eremicola, in its smaller 
eyes, the smaller punctures in the elytral strie, and the much 
less rugulose elytral interstices. 
Central Australia ; taken by Mr. Zietz near Lake Callabonna, 
C. minor, sp. nov. Oblongus ; piceo-niger, setis brevissimis ful- 
vis sparsim vestitus, antennis pedibusque picescentibus, 
tarsis dilutioribus ; capite sat crasse ruguloso, fronte im- 
pressa ; oculis parvis ; antennis prothoracem superantibus, 
apicem versus modice incrassatis, articulis 9° vix 10° leviter

antice arcuato-emarginato quam postice parum angustiori, 
postice fortiter bisinuato sed vix in medio lobato, lateribus 
parum arcuatis postice vix sinuatis, angulis posticis acutis,

May be distinguished superficially from its described con- 
geners by its small size and dark antenne in combination. It is 
also remarkable for the very slight curve of the sides of its pro-
