series of small shining granules. Uyider surface with dense but 

 more or less concealed punctures. Legs rather short and densely 

 punctate; femora stout, distinctly but not very strongly dentate, 

 posterior scarcely extending to apical segment; tibite feebly com- 

 pressed and bisinuate beneath, in addition to the (strong) terminal 

 hook each with a subapical tooth. Length 8, rostrum 2; width 

 4 mm. 



Hah. — N.W. Australia (type in Macleay Mus.). 



The pale patches of scales on the elytra are near the base and 

 on the posterior declivity; the basal patch extends from the 3rd 

 interstice to the margin, its anterior inner angle being marked 

 with a dark and perfectly circular velvety spot; the posterior 

 patch is irregularly semicircular in outline and commences on the 

 2nd interstice; its inner face at the middle is marked with an 

 angular dark spot similar in character to the basal one. 



Critomerus, n.g. 



Eyes large, rather finely faceted, subcontiguous. Rostrum 

 moderately long and rather thin but not rounded, lightly curved. 

 Cluh ovate, sutures straight. Pedoral canal terminated between 

 four anterior coxae. Abdomen with perfectly straight sutures, 1st 

 segment slightly longer than the two following combined, inter- 

 coxal process narrow, 2nd the length of 5th and very slightly 

 longer than 3rd or 4th. Anterior femora bidentate. Other 

 characters as in Perissops. 



Closely allied to Perissops, but the anterior femora bidentate. 

 The species described below appears to be a common one in 

 certain parts of Queensland. This genus is a highly interesting 

 one on account of the bidentate anterior femora. 



Critomerus emblem aticus, n.sp. 



Brownish-black, antennae of a dingy red. Densely clothed with 

 scales varying from a dark straw-colour to ochreous; prothorax 

 with small chocolate-brown scales except on sides, a few spots 

 scattered about, and a basal median patch that is suddenly
