Proposing from time to time to lay before the Society certain 

 notes, which I imagine may facilitate the study of this division of 

 the Curculionides, I will commence with those species which are 

 now arranged vuider the generic name Acantholoplius. The 

 species of this group are for the most part very similar to each 

 other, and undoubtedly are difficult to distinguish through the 

 published descriptions, on account of the differential characters 

 not being brought forward in any prominent manner : having, 

 however, had an opportunity of examining nearly all the original 

 types described in Schonherr's work — these types being in the 

 Rev. Mr. Hope's collection, now at Oxford — I have been thereby 

 enabled to throw them into a tabular form, which table I now lay 

 before the Society, hoping it may help those who may wisii to 

 study the group. 



AcANTHOLOPHUs (Mac Leay), Schonherr.

 A. With three I'ows of tubercles or 

 spines on each elytron, the outer

• The Australian Curculionides with a six-jointed funiculus to the antenna;, 

 including the genera Euomus, Mythites (Acatuhomus, Germ.), Tetralophus, Wat., 

 Amycterus, and Acantholoplius, form a very distinct and natural group, which 

 might be called Amycterida:. The so-called Brachycerus Australis of Germar 

 also belongs here. 



t A. Idieralis has a single large humeral spine, whilst A. suturalis has two or 

 three very small spines on the humeral angle of the elytra.
