composed of two parallel ridges, separated by a median linear 

 impression ; side widely ampiiate ] scrobes moderat'ely curved, 

 ending not far from eye. Head strongly convex, partially 

 concealed by prothorax; eyes rotundate, set well forward. 

 Antennae moderately long ; scape moderately incrassate, 

 passing eye, but not reaching prothorax ; funicle six-jointed ; 

 club obovate. Prothorax strongly produced into a cowl-like 

 median lobe, enclosing and partly concealing the head ; ocular 

 lobes j)resent, small ; disc of pronotum passing into sides with- 

 out definite demarcation. Elytra narrow, slightly widened 

 posteriorly ; posterior declivity almost perpendicular ; with 

 three rows of tubercles on each side of back. Under-surface 

 sloping posteriorly and dorsally from metasternum to apex of 

 second segment, thence practically flat to apex ; prosternum 

 not apparently excavate ; metasternum moderately short. Legs 

 moderately long, simple ; anterior tarsal joints short ; posterior 

 moderately long. 



The above genus is proposed for a most extraordinary 

 looking weevil. I think I am correct in assigning it to the 

 Amy derides, although I have seen it in Sydney collections 

 placed among the Aterpides. Although, in general facies, 

 unlike any Amycterid known to me, critical examination has 

 failed to reveal any character definitely excluding it from that 

 subfamily. The mouth parts I have not been able to dissect 

 out, but as far as I can judge on external examination, they 

 do not differ from the Amycterid type. The rostral structure 

 is not dissimilar from other Euomid genera. The six- jointed 

 funicle is typical of the Amycterides, although Aterpus 

 has also a six- jointed funicle. The short metasternum 

 without visible episterna is also characteristic. The tarsi are 

 like those of many other Amycterid genera. The dissimilarity 

 of the genus from other Amycterid genera arises from the shape 

 of the prothorax, and the setting of the elytral tubercles. In 

 regard to the prothorax, the extension is not more extra- 

 ordinary than, though very different from, that of DialeptopuSy 

 to which genus, indeed, CucuUothoracr seems most nearly 

 allied. The elytral tubercles are set on the back, in three 

 rows, placed closely together. I believe that these rows prob- 

 ably represent the first, third, and fifth interstices, the inter- 

 mediate ones having been crowded out and obliterated. In 

 other Amycterid genera it is difficult to trace the intermediate 

 interstices. I might add that Mr. A. M. Lea agrees with me 

 in allocating this genus to the Amycterides.
