12 DESCRIPTION OF NEW COLEOPTERA, 



vitta obliqua humerali fascia media undulata apiceque 

 lactifloreis. 

 Long. 5| lin., lat. 1| lin. 

 Hab. Port Denison. 

 Upper surface black, witb a sligbt bronzy splendour about 

 the bead and thoi-ax. Beneath very dark blue. Palpi and 

 labrum pale yellow, the latter margined with black. The elytra 

 have a short vitta sloping inwards from the shoulder, a wavy 

 fascia behind the middle, not reaching the suture, and the apex 

 cream coloured, while the legs are black. 



This species seems to be tolerably abundant about Port 

 Denison. 



6. D. CURSITANS. 



..lEneo-olivacea mandibulis labro antennarum articulo basali 

 pedibusque luridis ; elytrorum humero fascia media apice- 

 que flavis. 



Long. 5 lin., lat. Ij lin. 



Hab. Clarence River. 

 Upper surface of head, thorax, and elytra, bronsse ; beneath 

 bluish black, with a metallic brilliancy. The palpi, mandibles 

 labrum, basal joint of antennse and legs, are of a dirty yellow 

 colour. The elytra have a patch on the shoulders, a waved 

 post-median fascia, not reaching the suture, and the apex, yellow. 

 The only other species of this genus known to me, is a large 

 and well-known insect, which has been described by Westwood, 

 (Mag. Zool. Bot.; p. 291), under the name of imdulata, from 

 its peculiar transverse wavy sculpture. The two species I have 

 now described have the same peculiarity of sculpture : I have not, 

 however, made any mention of that peculiarity in the specific 

 descriptions, as I believe it to be a gener-ic character. The 

 large labrum, and general form of these insects, show a close 

 affinity to the genus Therates, which is still further indi- 

 cated by their similarity of habit, both genera frequenting 

 trees, and running rapidly over their leaves.
