 Group 2. 



EXITHIUS ATHYREUS, n. Sp. 



Black ; antennae and tarsi reddish. Densely clothed with 

 large soft scales, mostly fawn-coloured, but largely mixed with 

 black. Prothorax with six fascicles, elytra with many. 



Head with forehead marked off by a somewhat sinuous 

 depression, the depression interrupted by a short median ridge ; 

 with dense punctures, partially concealed in front. Rostrum 

 moderately stout, sides distinctly incurved to middle, strongly 

 notched on each side of base ; behind antennae with large 

 partially-concealed punctures, in front of same with smaller 

 clearly-defined ones, and a few minute ones interspersed. Scape 

 rather stout, inserted almost in middle of rostrum. Prothorax 

 moderately transverse, sides strongly rounded, apex half the 

 width of middle ; with rather large partially-concealed punc- 

 tures ; with a short and very feeble median carina or impunc- 

 tate line. Scutelluin absent. Elytra stout, sides irregularly 

 rounded, base trisinuate ; with rows of large, deep punctures, 

 becoming smaller posteriorly and partially concealed in places ; 

 suture with depressed granules on basal half, second to seventh 

 interstices with feeble tubercles supporting distinct fascicles. 

 Metasternal episterna very narrow, but frontal triangle dis- 

 tinct. Basal segment of abdomen flat in middle, each side of 

 base with an irregular impression, its suture with second con- 

 spicuously curved in middle. Femora stout, strongly dentate; 

 tibiae bent downwards in middle. Length, 6J-6| mm. 



Hah.—l^ew South Wales: Blue Mountains (E. W. Fer- 

 guson) . 



In appearance close to a large variety of fumatus, but 

 head depressed near forehead, and base of rostrum more con- 

 spicuously notched on each side (on most specimens of fumatus 

 the notches are either not present or are almost concealed by 

 clothing, and only visible from behind). On the elytra there 

 are several feeble transverse patches of whitish scales ; the 

 abdomen is almost entirely clothed with sooty scales, and on 

 the prothorax they are in the majority. On the head the scales 

 are dingy, but feebly variegated. The club is somewhat darker 

 than the rest of the antennae. The suture and the lateral inter- 

 stices are the only ones without fascicles. The two typical 

 specimens are probably males. 



EXITHIUS INTERMIXTUS, U. Sp. 



Blackish; antennae and tarsi reddish. Densely clothed 

 with large soft scales, varying from whitish to sooty. Pro- 

 thorax with six feeble fascicles, elytra with many. 



Head evenly convex; with very dense punctures, larger
