less than fourth and fifth combined, fourth to eighth sub- 

 equal, remaining joints wanting. Prothorax 4 x 2*5 mm., 

 narrow and truncate at apex, slightly sinuous at base, sides 

 (seen from above) almost straightly converging from base to 

 apex, (from side-view) moderately and evenly arcuate, all 

 angles obtuse (seen from above, posterior angles appear 

 rectangular); distinctly, evenly, punctate, with evident 

 laevigate central line. Scutellum black, triangular, im- 

 punctate. Elytra elongate and cylindric, slightly enlarged 

 behind the middle; seriate-punctate, with punctures of even 

 size and distance apart; intervals quite flat and strongly 

 punctate (both seriate and interstitial punctures very much 

 as in C. variabilis, Bless., but the former more even in size 

 and more close, the latter a little finer). Abdomen finely 

 and regularly punctate, the flanks more strongly so, meta- 

 stenium sparsely punctate at the sides only, prosternum with 

 a small carina, posterior tarsi with basal joint shorter than 

 the rest combined. Dimensions — 13-14 x 6'5 mm. 



Hab. — Queensland. 



Three specimens (with mutilated antennae) were given 

 me by Mr. A. M. Lea. The species evidently differs from 

 C. cylindricus, Blkb., by its black tarsal clothing and the 

 finer seriate punctures of the elytra (w^iich in cylindricus re- 

 semble the intermediate rows of C. punctipennis , MacL). The 

 colours are not exceptionally brilliant, as is the case in C. 

 cylindricus, which, moreover, is slightly narrower than the 

 above, with the prothorax a different shape. It differs from 

 C. 2^^^^^ongus, Blkb., in its duller black, shorter, and more 

 rounded prothorax, shorter and more convex (longitudinally) 

 elytra, with the interstitial punctures stronger. Types in the^ 

 author's collection. 



Chalcopterus prismaticus, n. sp. 



Elongate-ovate, parallel, head, pronotum, and under- 

 side very nitid-biack, elytra splendidly versicolorous in vittae, 

 i.e., suture purple, then one interstice blue, next two inter- 

 stices gold or greenish, then purple, gold, or green, with 

 shoulders, sides, and epipleurae blue. 



Head densely punctate, without laevigate intervals, fche^ 

 punctures round, deep, and neither rugose nor confluent ; eyes 

 widely separated (more widely than in C. a-ffinis, Bless.), with- 

 out ocular sulcus; antennae long, joint three longer than first 

 and second combined, and nearly, or quite, as long as fourth 

 and fifth combined, fourth to eleventh of nearly equal length, 

 evidently widened towards apex. Prothorax 3x5 mm., very 

 convex, apex truncate, base slightly lobate in the middle, sides 

 rather widely and evenly rounded and arcuately converging
