second. Profliorax rather lightly transverse, sides moderately 

 rounded, base feebly bisinuate : punctures normally concealed. 

 Elytra moderately long, not much wider than prothorax, 

 parallel-sided to beyond tlie middle, subtuberculate beneath 

 fascicles; with rows of large partially-concealed punctures. 

 Mesosternal receptacle rather strongly elevated, base large and 

 ridged along middle ; emargination with thin U-shaped walls. 

 Ftmora feebly dentate. Length, 3 J mm. 



9 . Differs in having the rostrum thinner, with much 

 smaller and sparser punctures, and less of the base clothed. 



Hah. — New South Wales: Acacia Creek (H. J. Carter). 



The antennal insertion is as in rever.^us, but the two 

 species are otherwise very different. The base of the meso- 

 sternal receptacle is wider than in the more typical species of 

 the genus. There is an elongated velvety patch or loose fascicle 

 on each side of the middle on the basal half of the prothorax. 

 On the elytra there are three on the third interstice, one on 

 the fifth, and two on the seventh : the largest of all is the sub- 

 basal one on the third, and this is so thickly beset with erect 

 blackish scales that it could fairly be regarded as a fascicle.. 

 On the elytra also there are elongated spaces on which the scales 

 are slightly paler than the surrounding ones. 



Tychreus aberrans, n. sp. 



Of a dingy reddish-brown ; antennae and tarsi paler. 

 Densely clothed with scales, mostly fawn-coloured, but varie- 

 gated with sooty and white ; with stout scales scattered about 

 and in places condensed into fascicles. 



Eyes large and coarsely faceted. Rostrum moderately 

 long, sides lightly incurved to middle ; basal two-fifths with 

 concealed sculpture, elsewhere shining and with rather coarse 

 punctures. Scape shorter than funicle, inserted in middle of 

 rostrum ; club ovate. Prothorax moderately transverse, apical 

 third much narrower than elsewhere, base lightly trisinuate ; 

 punctures normally concealed. Elytra moderately long, 

 decidedly wider than prothorax, parallel-sided to near apex, 

 subhumeral incurvation scarcely noticeable ; with rows of large, 

 almost concealed punctures ; subtuberculate beneath fascicles. 

 Mesosternal receptacle widely U-shaped, walls thin and feebly 

 raised. Four hind femora lighty dentate, the others not at 

 all. Length, 3| mm. 



Hah.—lSiew South Wales: Comboyne (W. H. Muldoon). 



The edentate front femora ^^5) and coarsely faceted eyes 

 are aberrant in Tychreus; but as the species in general appear- 

 ance is very close to dilaticollis, reversus, and fumosus, it 



(45) The teeth of the four hind femora are very minute, and 

 could easily be overlooked.
