Hab. — New South Wales (Macleay Museum). 



The narrowest of the genus. I cannot find the least trace 

 of a carina on the head of the specimen described, but this is 

 probably a character that is not to be too strictly relied upon, 

 as in oblong opunctatus one specimen has the head carinate, 

 whilst another has not. The depressions on the prothorax, 

 although not very deep, are sufficiently distinct; there are 

 three subbasal ones, and a semicircular one (at its posterior 

 end rather deeper than elsewhere) on each side of the carina. 



Omydaus confusus, n. sp. 



Clothing somewhat as in oblon g opunctatus . 



Head coarsely punctate ; with a feeble median carina ; 

 eyes moderately faceted. Rostrum almost parallel-sided ; 

 •coarsely punctate on basal half, not very coarsely on apical. 

 Antennas rather stout; scape noticeably shorter than funicle. 

 Shape much as in oblong opunctatus, but rather narrower; the 

 prothorax with larger and deeper punctures and the median 

 •carina more pronounced; the elytra with smaller punctures, 

 much less clearly defined and more or less confluent. Length, 

 7^ mm.; rostrum, 1J mm.; width, 2A mm. 



Hah. — New South Wales: Tamworth (A. M. Lea). 



Close to oblong opunctatus but smaller and narrower, and 

 with different punctures. The elytral interstices are feebly 

 connected in places, causing feeble transverse subtubercular 

 spaces ; the anterior tibiae are not very strongly bisinuate, and 

 are without the median tooth of oblongopunctatus , the sub- 

 apical tooth, however, is rather distinct. 



PSEUDOMYDAUS, n. g. 



Eyes rather small, coarsely faceted. Rostrum rather 

 stout. Scape much shorter than funicle, inserted almost in 

 middle. Prothorax longer than wide. Elytra more than twice 

 the length of prothorax. Abdomen with the second segment 

 almost as long as the two following combined, its suture with 

 first deep at sides only and curved across middle. Legs 

 moderately long; femora stout, edentate. Other characters 

 as in Omydaus. 



The species described below is not unlike a small variety 

 of Omydaus impressicollis, but the characters given above are 

 so much at variance with those of Omydaus that it certainly 

 should not be placed in that genus. 



PSEUDOMYDAUS TENUIS, n. sp. 



Black, antennae and tarsi of a dingy-red. Moderately- 

 densely clothed with reddish-brown and rather elongate scales, 

 on the prothorax one in each puncture; elytra in addition
