Notes on Aiuycterides. 253 



Though I have iihicid this ltuiij) among the tuberculate species, 

 it is evidently ii<it iinah at home tliere, both this species and 

 nielancholicus being strongly costate species, and yet they cannot be 

 separated from their congeners of the same group. 



The distribution of these two species, one found at Mt. Kosciusko, 

 the other extending from Mt. Macedon into S. Australia, would 

 suggest tho possil)ility of otlicr foinis occurring in the intervening 

 jirea. 



Talauuixis cahinatus, n. sp. 



d Clo.sely resembling 2\ costipennis; elongate, ovate. Black 

 subnitid, practically without clothing above, a small patch of yellow 

 scales in middle of each ventral segment. 



Head convex, external rostral ridges continued back into head, 

 forehead somewhat concave between the ridges. Rostrum narrow, 

 internal ridges long, rather feebly convergent, sublateral sulci and 

 jiiedian area narrowly and deeply depressed, rostrum deeply ex- 

 cavate in front. Eyes subrotundate. Scape moderately long, 

 strongly incrassate, scrobes simple, not quite reaching eyes. Pro- 

 .thorax (3.5 x 4 mm.) gently rounded on sides, apical margin trun- 

 cate above, postocular sinuation strongly marked; disc with minute 

 granules closely set, smaller and more depressed than in costijjennis ; 

 sides with similar granules. Elytra (10 x 6 mm.) moderately 

 strongly dilate on sides, apex moderately produced mucronate, base 

 rather feebly arcuate, humeri thickened, somewhat noduliform, not 

 gieatly produced. Disc with rows of subquadrate foveae becoming 

 smaller and less distinct posteriorly, arranged in double rows, the 

 second and fourth interstices being absent, outer row in single 

 series, the sixth interstice present ; interstices one and three costi- 

 form, three particularly prominent and carinate, five costiform 

 showing evidences of granularity, sixth interstice with similar but 

 more evident granularity; sides with irregular punctiform foveae, 

 interstices granulate. Beneath concavo-convex, apical segment with 

 shallow, ill-defined subquadrate impression occupying middle two- 

 fourths. Legs simple, femora not ridged or dentate. $ Rather 

 larger and more obese, prothorax (4 x 4.5 mm.) and elytra (lU x 

 €.5 mm.) with similar sculpture, the fifth elytral interstice showing 

 jSk greater tendency to granularity. Beneath convex, fifth segment 

 with shallow rounded impression at apex. 



Dimensions. — <? 15 x 6 mm. ; J 1(5 x 6.5 mm.
