faint, pale V can be traced, commencing on each shoulder and 

 directed towards the sutural third; immediately behind the 

 V is a large, irregular, indistinct dark triangle on each side. 

 The V and the triangles are never sharply defined. The male 

 has the rostrum clothed more than half way to the antennae ; 

 whilst in the female the scales are confined to the base. The 

 species is the largest known of its genus. 



211. Decilaus sobriiius, n. sp. 



Black, antennae and tarsi reddish, tibiae somewhat darker. 

 Sparsely clothed with whitish scales, becoming pale brown in 

 places ; each el3'tron with a distinct aond fairly large pale spot 

 near the ajj^ex. 



Head with dense and moderately coarse punctures, becoming 

 smaller posteriorly. Rostrum with crowded punctures, de- 

 cidedly coarser than on head. Scape inserted one-third from 

 apex of rostrum, not much shorter than funicle ; first joint of 

 the latter distinctly longer than second ; club apparently con- 

 tinuous with funicle. Prothorav about once aind one^-third as 

 wide as long, sides strongly diminishing to apex on apical half 

 only ; with dense, round and fairly coarse punctures, decreasing 

 in size to apex. Elytra Avidest near base ; with rows of large, 

 round punctures ; interstices convex, each with a row of small 

 and distinct, but seldom conspicuous granules. Abdomen with 

 fairly numerous and moderately large punctures (Ui two basal 

 segments, suture between these almost obliterated in middle. 

 Tibiae Avith fine carinae partially concealing rows of punctures. 

 Length, 4 — 4i mm. 



Also from Victoria. 



An obscure species close to perditus. but much more sparsely 

 clothed, prothorax narrower and with larger punctures, abdo- 

 men with larger and sparser jiunctiu'es, tlie elytral interstices 

 feebly granulated and more convex. Tlie abdominal punc- 

 tures are smaller ajid more numerous than in memnonius. and 

 those on the prothorax are smaller, denser and shallower. 



212. Decilaus Jiiixlus, n. sp. 



IMack or piceous-brown ; elytra sometimes paler tluui pro- 

 thorax ; antennae and tarsi reddish. Densely clothed witli soft 

 scales varying from snowy white to sooty.
