Adelium subdepressum, n.sp. 

 (Plate iii., fig.3.) 



Elongate-ovate, rather flat; bright purple-bronze, moderately 

 shining; oral organs, antennae and tarsi reddish-brown, beneath 

 a darker bronze shining. 



Head rather coarsely punctate, epistomal ridge sharply defined 

 behind by arcuate groove. Antennae elongate in the male, joints 

 lineate, and only slightly thickened towards the apex, third joint 

 about equal to fourth and fifth jointly. Prothorax nearly twice 

 as broad as long, very little convex, and widely explanate, with 

 greatest width behind the middle, moderately striate in front, 

 truncate at base, narrower at base than at apex; sides widely 

 rounded, scarcely sinuate near anterior angles, more abruptly 

 converging at posterior angles, the former of these slightly pro- 

 duced and obtuse, the latter obsolete, a narrow raised border 

 throughout strongly defined towards anterior angles, less percepti- 

 ble elsewhere. Disc very lightly rugose, with shallow punctiform 

 impressions. Central canal faintly impressed on middle portion. 

 A few setigerous punctures on the explanate margins. Elytra 

 about as wide as prothorax at widest and about two and a half 

 times as long. Shoulders widely rounded and sharply margined. 

 Disc somewhat flat and depressed at suture, striate-punctate, with 

 ten rows of punctures on each elytron, the last two on the sides, 

 the punctures large, transverse and close; intervals very slightly 

 raised but strongly tuberculate towards sides and apex. Last 

 segment of abdomen strongly punctured. Intercoxal process 

 margined and rounded. Dimensions — £ 145 x 5*5 mm.; 9 16*5 x 

 7 mm. 



Log. — Bombala and Moruya, N. S.W. 



I am indebted to Mr. Cheesman, of Moruya, for the three 

 specimens I possess. I adopt the MS. name with which I found 

 a similar insect labelled in the Bates Collection of the British 

 Museum with other undescribed Adelia. It is easily recognised 

 by the combination of bright bronze colouring and strongly 

 tuberculate elytra and depressed form.
