2. Aulacocyeliis rotuiidatoclypeatiis Kuw. — 14 spec- 

 imens from Atherton, Herberton, Cedar Creek and Malanda, 

 January to April, 1913. 



3. Aulacocyclus Kaupi Mc Leay. — 15 specimens from

4. Aulacocyclus tambourineusis n. sp. (Fig. 4). — 

 Allied to the group parryi-perlatus-arnensis especially to the 

 latter, but differing in many important points. 



Elongate, convex, glossy, deeply striated on the upper 

 surface of the elytra as vvell as on the sides. Head shining 

 (clypeus microscopically reticulated, with 

 fine punctures near the anterior margin), 

 and strongly punctured behind theeyes; 

 the whole surface very glossy especially

 of Aulacocyclus tam- ^ characteristic in shape: it projects

from a very solid base and is horizont- 

 ally bent forward i. e. taking the shape of a hook; its dors- 

 al surface is parallel to the surface of prothorax and has a 

 deep longitudinal groove very nearly for its whole length. 

 Prothorax with a deeply sunk median line; the lateral marg- 

 in is all round provided with large and deep punctures; the 

 lateral impression is very strongly marked, very deep and 

 S-shaped and very strongly punctured; the anterior angles 

 distinctly produced. Elytra shiny, very distinctly punctur- 

 ed, with a broad area at the tips entirely opaque and only 

 marked by some scattered punctures. Metasternum in front 

 of the posterior edge with a distinct transverse depression. — 

 Length 25—30 mm. Breadth 9—10,5 mm. 



By the shape of the frontal horn, the puncture and shape of 

 prothorax, and the broad large opaque area on cither tip of 

 elytra, this species is easily distinguishable from its relatives. 

 All the eigtheen specimens correspond to the above mentioned 

 characteristics.
