Colcopterd of Kimj Ixln ml. 199 



slitrlitly narrower than protlmrax, [laralk-l-sitled tn lifyond the 

 middle, extreme base slightly raised and slifjhtly rugose; with 

 almost regular series of small punctures, and with very feeble 

 traces of striation. Under ■'Surface with small and Sllar^^e 

 punctures, larger on meso and metasternum than elsewhere. 

 J-,ength (including rostrum), H — 3 mm. 



Fairly common under drift wood on Ijeaches ; and occurs in 

 siniilaa' situations in Tasmania (Sorell, Hobart and Nubeena). 



The difference in .size and a.ppearance of some of the speci- 

 mens is very great, but I am satisfied that they all belong to 

 but one species. Tlie larger specimens are nearly always black, 

 whilst the smaller ones are often of a deep reddish brown ; occa- 

 sionally the prothorax only is reddish-l)rown, or its sides and 

 the sides of the elytra may l)e so coloured.

Black, the legs and antennae in places reddish, the elytra in 

 ]ilaces diluted with red. Densely clothed with short setae or 

 pubescence, varying from white, through various shade.s of 

 yellow and brown, to black, and in places forming fasciclej* ; 

 legs annulated. 



Head with dense partially concealed punctures. Rostruiu 

 .strongly inflated tow'ards the apex, with three narrow shining 

 carinae, of which the mediain one is longer than the othei's ; 

 punctures as on head. Antennae not extending to base of pro- 

 thorax, first joint slightly shoi'ter than second, the combined 

 length of both not much greater than that of third, the others 

 rather stx'ongly decreasing in length, but none transverse. 

 I'rothnrar about as long as its gi'eatest width, which is just 

 behind the middle, sides strongly rounded : towa.rds base with 

 a strong sinuiius carina, interru]ited in its middle, and at the 

 sides directed obliquely forwards : with dense partially con- 

 cealed punctures, and with three very feeble tubercles trans- 

 versely placed across the middle. Ehjtra parallel sided to near 

 apex, somewhat tiattened aloii'^- middle : with rows of moderate
