Table of Tasmanian species. 



1 (4) Elytra deeply and fully striate, interstices convex, particularly at 



apex. 



2 (31 Elytra with apical sinuosities obsolescent. Length, . 15 — 20 mm. 



politulus Chai'.d. 



3 (2) Elvtra with apical sinuosities well marked, (third interstice inflated 



near apex, in ? protuberant; a triangular projection on lateral 

 border on each side of apex in S). Length, 16.5 — 18 mm. 



ttiberiiaudiis Bates. 



4 (1) Elytral striae (excepting eigh-th) faint or obsolete, interstices de- 



pressed. 

 5 (61 Elvtra with lateral border narrow near base, basal border forming a 

 blunt protuberance at humeral angles. Length, 13 — 16 mm. 



chalybeus Dej. 



6 (5) Elytra with lateral border strongly refiexed near base, .basal border 



uniting with lateral border at humeral angles without a marked

NoTONOMUS POLITULUS Chaudoir. 



This species is widely distributed in Tasmania; specimens are in the Simson 

 Coll. from Launceston, Denison Gorge, Ben Lomond (4000 feet), Forester River, 

 Wynyard, Straban, Zeehan, Mount Wellington (Nos. 3056, 3090), Flinders Is. 

 (No. 2728). It occurs at Cradle Mountain, Waratah, Straban (Carter and Lea). 

 In the long series of specimens brought from Waratab by Mr. Lea in January, 

 1918, the number of punctures on the third interstice of the elytra varies from two 

 to four; some specimens had the protborax a little more narrowed to 'the base, and 

 the elytra more rounded on the sides than usual, but all were evidently of one 

 species . 



NoTONOMUS TUBERic'AUDUS Bates. 



It is easy to distinguish the ? of this species from the $ of iV. politulw! 

 Chaud., by the ante-apical protuberance of the third interstice of the elytra, and 

 the triangular projection on the border near the apex; but to separate the t? is 

 not so easy; the third interstice is a little swollen at apex, and the fourth interstice 

 curves round the extremity of the third in a way it does not do in N. jiolitulus; 

 the lateral apical sinuosities also are more decided.
