minent but rounded, epipleural fold reflexed and emphasised : 

 disc with eight well marked sxilci above, a row of large, close 

 punctures on sides, and a further svilcus on extreme outside, 

 intervals strongly convex, the third, fifth, and seventh 

 slightly more raised than the intervening intervals (though 

 this character is variable in my specimens) ; the eighth (on 

 sides) not extending to base, the fifth and seventh discon- 

 nected at apex, and enclosed by connected pairs of inter- 

 vals ; epipleurae smooth. Under surface smooth, fore tibiae 

 with inner surface swollen and subnodulose in the middle, 

 curved and carinate on outside edge, tufted and expanded at 

 apex, with one long and one very short spur on inside of 

 apex ; intermediate tibiae with a smaller enlargement near 

 base, posterior tibiae curved and armed with a row of tubercles 

 on the inside. 



Q. Size larger, tibiae very little curved, and without the 

 tibial swellings or tubercles noted above, posterior tarsi

Hah. — Dalveen, South Queensland. 



Thirteen specimens were taken by the author in January, 

 1911, five males, eight females. The strongly marked sexual 

 characters of the tibise in the above species will sufficiently 

 differentiate it. It is otherwise closely allied to C . opacicolUs 

 Macl., (of whicli I have cotypes;, other differences being 

 that, in (' . o'paricollis, the antennal joints are more elongate, 

 the prothorax is longer than broad, with larger and more 

 acute posterior angles, the elytral intervals are regular and 

 its colour is opaque black. 



Adelium arboricola, n.sp. 



Rather widely ovate ; head, thorax, and legs metallic 

 green ; elytra brown, with a greenish tint ; abdomen dark 

 metallic chestnut, very nitid ; oral organs, antenna?, tarsi, 

 and tibial vestiture light red. 



11 end coarsely and regularly punctate, labrum prominent, 

 epistoma rounded, not reflexed, limiting suture wide, deep
