Notes on Australian Cureulionidae in the Berlin Museum. 201 
257. C. praeustus, Redt. 
258. Pentamimus canaliculatus, Woll. 
259. Phloeophagosoma polixum, Er. (Kthyneolus). 
A specimen labelled “Arhyneolus prolisus Er. Type? Terr Van Diem Schayer” 
agrees well with the description of this species, and is probably the type, or a co-type. 
The species was omitted from Masters’ Oatalogue*). J have five specimens from 
Hobart, Swansea and Parattah, and all have the rostrum more or less diluted with 
red. In the museum specimen the rostrum is less noticeably diluted with red, and no 
mention is made of its colour in the original description. The funicle is seven jointed. 
From the European R. ater (stated by Wollaston to be the type of /rhyneolus), 
it differs in being thinner, in having the rostrum longer and much thinner, the scape 
longer, thinner, and curved at apex, and the funiele and tarsi thinner. It appears 
to agree better with Phlaeophagosoma than any other genus described by Wollaston, 
and at present I can see no reason why it should not be referred to that genus. 
*) Rhyncolus australus, Er., also omitted from the catalogue, I have from many parts of 
Tasmania; it varies from a dingy red almost to black. It is a Pentarthrum, differing from nigrum 
in having a shorter rostrum, and denser and smaller prothoraeie punetures.
