158 NOTES ON AUSTRALIAN COLEOPTERA, 



vex, sides of prothorax sinuate in front, the acute anterior angles 

 pointing obliquely outwards, lateral border less strongly raised, 

 pro-tibiae slightly, mid-tibia? more strongly curved. Dimensions: 

 19| x 8 mm. 



Ilah. — Buchan, Gippsland. 



N.B. — A somewhat similar sexual difference in structure of 

 prothorax exists in Aitausis metallescens Westw., (vide These Pro- 

 ceedfugs, 1913, p. 71). The identity of sculpture of the Buchan 

 and Cassilis specimens, and the near neighbourhood of these 

 places are reasons for considering the Buchan as the £ of the 

 Cassilis specimens. 



Byallius punctatus, n.sp. 



Elongate, obovate, subopaque black, elytra and legs more 

 nitid, antenna; reddish ; tarsi and apex of tibiae clothed with 

 golden tomentum. 



Mead as in B. reticulatus, but more coarsely punctate. Pro- 

 thorax 5x7 mm., arcuate-emarginate at apex, anterior angles 

 sharply acute, pointing a little outwards and upwards, sides 

 widest behind middle, thence arcuately converging gradually 

 forward, more abruptly behind, sinuate near front and hind 

 angles, the latter subrectangular and emphasized by the sudden 

 termination of the strongly reflexed and thickened lateral border, 

 base truncate; apex and base narrowly bordered, disc strongly 

 but unevenly punctate, with a clearly defined, smooth, medial 

 line and some smooth spaces near centre. Scutellum transversely 

 triangular and punctate. Elytra lightly obovate, vermiculately 

 rugose, with three well-raised wavy costa?, the intervals showing- 

 sparse, rather large punctures. Whole underside and legs 

 coarsely and closely punctate, the abdominal punctures becoming- 

 finer and denser towards apex, the last segment very densely 

 pitted. Dimensions: 18x8|mm. 



llab. — Cunningham (Lakes Entrance), Gippsland, Vic. 



A single example taken by me in January, 1909, can be clearly 

 distinguished from B. reticulatus by its strongly raised elytral 

 cost*, its thinner and more vertically raised lateral border to 

 prothorax, with its smooth medial line, sharper posterior angles,
