portion transverse, and with somewhat denser and stronger punc- 

 tures than behind antennae, where they are much the same as 

 between the eyes. Prothorax almost twice as long as width of 

 base, sides gently dilated from near apex to beyond the middle, 

 and then more strongly rounded to base; with fairly numerous 

 and rather large, non-confluent punctures, becoming smaller and 

 more crowded on sides. Elytra subcylindrical, slightly narrower 

 than greatest width of prothorax, with rows of fairly large, round 

 punctures, becoming smaller posteriorly; interstices with sparse 

 and very minute punctures. Length, 3|-3| mm. 



Hah. — Queensland: Cairns (E. Allen and J. A. Anderson). 



The smallest and narrowest species of the genus known from 

 Australia. The largest punctures on the elytra are somewhat 

 smaller than the median ones on the prothorax. 



COSSONUS FRENCHI, n.sp. 



Black, shining; appendages dark red. 



Head with small but clearly defined punctures; with a small 

 interocular fovea, vaguely connected with a shallow but distinct 

 median line on rostrum. Rostrum about once and one-half as 

 long as greatest width, strongly narrowed behind antennae, punc- 

 tures towards base much the same as between eyes, becoming 

 denser on sides and in front. Prothorax somewhat depressed, 

 about one-fourth longer than greatest width, base rather strongly 

 bisinuate, and almost twice the width of apex, sides rounded and 

 increasing in width from near apex to near base; with numerous 

 rather large punctures, becoming dense and smaller, but still 

 fairly large, on sides, and minute at apex. Elytra subcylindrical, 

 no wider than widest portion of prothorax, with rows of large 

 punctures, becoming much smaller before middle ; interstices 

 with minute punctures. Length, ^\-^\ mm. 



Hah. — Queensland. 



Distinguished from C. coptorhinus by the absence of a distinct 

 impression along each side of the median line; from the other 

 black Australian species, readily distinguished by the grooved 

 rostrum, and prothorax without a triangular basal impression. 

 The prothoracic punctures are somew^iat as on the preceding
