156 NOTES ON AUSTRALIAN COLEOPTEBA 



striate elytra, and general fades would place it not far from 

 Bolbophanes. 



Styrus puncticollis, n.sp. (Plate i\\, fig.3). 



Elongate ovate, opaque black, apical joints of antenna 1 brown, 

 tarsi clad with golden toinentum. 



Head closely rugose-punctate, antennae with joint 3 as long as 

 4-5 combined, gradually increasing outwards, last four joints 

 oval. Prothorax widest behind middle, base wider than apex, 

 arcuate-emarginate at apex, front angles acute and produced, 

 base subtruncate, sides moderately rounded, witli an irregular 

 more or less undulate outline, feebly sinuate behind, posterior 

 angles subrectangular and, in general, scarcely dentate: lateral 

 border thick and round, somewhat recurved, concave within; 

 disc closely bat not evenly punctate, with occasional smooth 

 spaces, without medial line. Scutellum widely transverse, smooth. 

 Elytra wider than prothorax at base, and more than twice as 

 long, lightly obovate; surface irregularly alutaceous, the suture 

 raised, and three irregular, shining, crenulate costal occasionally 

 connected by finer transverse ridges; the interstices everywhere 

 showing large punctures; underside similarly pit ted, the punc- 

 tures smaller on apical segments. Tibia' nearly straight and 

 unarmed. Dimensions: 16-20 x 6 A- 8 mm. 



Hah.— Capertee, N.S.W. (T. G. Sloane and H. J. Carter). 



Twenty-one specimens taken in Dec, 1918 (during a very dry 

 period), under logs or dead leaves, show a species allied to S. 

 latior Cart., but differing as follows: sides of prothorax less 

 widened, not sinuate anteriorly and much less so posteriorly, 

 elytral costre more sharply defined — the most definite distinction 

 being the strongly punctate pronotum (that of >S'. latior being 

 almost impunctate). There is considerable variation in the hind 

 angles of prothorax, which in general are scarcely dentate, but 

 in a few cases the sinuation is more marked and subangulate, 

 forming a distinct tooth.
