#a&.— Cairns, N.Q. (Mr. H. Hacker). 



I am indebted to Mr. Hacker for this beautiful Helopid. Its- 

 striking feature is its colour and metallic sheen, so that in the 

 sunlight its faceted pronotum and metallic elytra scintillate like 

 those of the most beautiful Chrysomelida? or Buprestidse. It is 

 entirely distinct from any other Adelium in this respect. 



Adelium nitidum, n.sp. 



Bright copper colour, shining; legs and abdomen darker;. 



antenna? dark brown. 



Head rather narrow, closely and regularly punctate. Usual 

 frontal impression definite. Antenna? long, reaching 

 to base of pronotum, 3rd joint shorter than 4th 

 and 5th combined, 11th much larger than 10th. 

 Prothorax (2*5 x 4 mm.) widest at middle. Sides 

 regularly rounded and deflexed; scarcely or obtusely 

 angulate anteriorly and posteriorly; lightly rounded 

 at apex, truncate at base; strongly convex, closely 

 and minutely punctate, with a few larger punctures 

 on disc, and shallow longitudinal sulci near the 

 lateral slopes. Elytra (5-5 x 4mm.) convex, ovate. 

 Shoulders rounded and widely separated from the 

 pronotum. Feebly striate-punctate, stria? consisting 

 of lines of long shallow punctures, irregular in size 

 and continuity; scarcely- perceptible at apex and 



sides. Intervals flat and minutely punctate. Abdomen and
