BY ARTHUR M. LEA. ' 199 



Head longer than wide, rather strongly convex in middle, 

 covered with shallow, honeycomb-like punctures, each of which 

 has a small central pit. Antennae slightly passing base of pro- 

 thorax, 2nd joint more than half the length of 3rd. Prothorax 

 ovate, with punctures as on head. Elytra as long as prothorax, 

 but at their widest narrower than its widest; with strong, rather 

 dense and clearly defined punctures. Abdomen dilated towards, 

 but not to, apex, with rather small setiferous punctures in more 

 or less regular transverse rows. Apterous. Length to apex of 

 elytra 2, of abdomen 3 J mm. 



Hab. — Launceston (Aug. Simson), Hobart, Huon River, 

 Frankford, Tasm. (A. M. Lea). 



The colours as given above apply only to one of the specimens 

 before me; a second differs in having the 5th abdominal segment 

 no darker than the 1st; a third has the whole of the upper surface 

 pale except the base of the elytra (which is not very dark, how- 

 ever), and the 6th abdominal segment which (except at its tip) 

 is almost black; the 4th has the whole of the upper surface of 

 a dark brown, except the apex of the elytra and of the abdomen. 

 One of the specimens was taken from moss and another from 

 tussocks. 



In general appearance rather close to S. guttida, but apterous, 

 and elytra not maculate. 



Sunius favosus, n.sp. 



(Plate xviii., tig. 3.) 



Almost black; mouth-parts reddish, appendages and apex of 

 elytra flavous. Clothed with straggling blackish hairs and with 

 greyish pubescence. 



Head longer than wide, moderately convex in middle, with a 

 narrow plate-like expansion at sides of antennae; with punctures 

 as on head of preceding species. Antenna3 thin, just passing 

 base of prothorax, 2nd joint scarcely half the length of 3rd. 

 Prothorax and elytra much as in the preceding species, except 

 that the elytral punctures are more numerous, although fully as 

 large. Abdomen slightly diminishing in width to base and apex,
