reirarded as of specific importance, but that the clothing of the 

 abdomen is of the saane remarkable nature as in the types. 



215. Decilaus acerosiis, .Er. 



Referred by Erichson to Acalles, but belongs to this genus. It 

 is a comm<in species near the coast, both on King Island and 

 Tasmania). 



210. Acliopcra subiilosa, ii. sp. 



lUack or Ijlackish-brown, antennae and tarsi reddish. Very 

 densely clothed with large, soft, round scales, closely applied to 

 the derm ; sides of prothorax. alternate interstices of elytra and 

 under surface with hm'ger semideoumbent and not rounded 

 scales, usually fawn-coloured : legs with setose scales and setae. 



Antennae short, inserted almost in exact middle of sides of 

 rostrum : scape vers' stout, not much more than half the length 

 of fui^iclc : the latter with first ji'int longer auil sf cuter than 

 sectind, third to seventh transverse. Frothorar apparently as 

 long as wide, but really slightly transverse, base bisinuate. 

 Elytra conjointly trisinuate at base, apparently lightly striate. 

 Length, 4—5 mm. 



Also from Tasmania (Hobart and Ulverstone). 



Tlie derm and punctures (except sometimes that some of those 

 in the elytral striae can be traced) are entirely concealed before 

 abrasion. The scales are mostly of ai pale faAXTi colour, but more 

 (ir less mottled with white or whitish and pale brown, dark 

 brown and blackish scales. There is usually a whitish some- 

 what oblique spot on each elytron about the basal third on the 

 fourth interstice (usuailly also extending to the third and fifth), 

 and a sooty spot on each side of the base of the prothorax. The 

 ordinary scales of the abdomen are much darker along the 

 middle than on tho sides. On the legs faint traces of rings are 

 usually to be seen. 



On abrasion the head is seen to be densely covered with small 

 round punctures, becoming smaller on the rostrum (on the ros- 

 trum of the fema.le they are normally exposed except at the base, 

 whilst, in the male they are exposed only towards the apex). On 

 the prothorax they are eciually as dense and rather larger. The 

 punctures in the elytral striae are large and close together ; the
