126 NOTES ON AUSTRALIAN COLEOPTERA, 



and the club is nearly as long as the last 3 joints of the funiculus 

 together. The joints of the funiculus scarcely differ inter se, save 

 in the basal joint being a little stouter than the rest. The tarsi 

 are very short and parallel (the 3rd joint scarcely wider than 

 either of the preceding) and are tomentose on their under surface. 

 The metasternum is longer than in most of the Amycterince, being 

 about as it is in some of the Cylindrorhinince. The basal two 

 ventral segments are elongate, the 3rd and 4th together a trifle 

 shorter than the 2nd, and longer than the 5th. The whole surface 

 is entirely devoid of the tubercles and spines so characteristic 

 of the Amycterinoi. 



I am in some doubt as to the sub-family in which this remark- 

 able species should be placed. Its very short and extremely 

 robust rostrum, with the mentum deeply sunk in the buccal 

 cavity is so characteristic of an Amycferid that I have given that 

 character the preference in determining its place. But the 

 metasternum is certainly inconsistently long, and the tomentosity 

 of the underside of the tarsi (which latter, however, is found in 

 Melanegis), and the absence of tubercles, &c., perhaps point to 

 Bothynorhyyichus as a nearer ally. The latter genus I have not 

 seen, but according to description the present insect could certainly 

 not be referred to it as it differs inter alia from Bothynorhynchus 

 by the short scape of its antennae and the strong ocular lobes of 

 its prothorax. It may be observed, however, that Bothynorhynchus 

 itself is regarded by Schonherr as being very near the Aviycterince, 

 and is differentiated by Lacordaire only by the tomentosity of 

 the undersurface of the tarsi, — which character loses its value by 

 its presence in Melanegis (not known to Lacordaire), — apparently 

 in all other respects a perfectly typical Amycterid.
