A single veteran (sex ? ) in the Australian Museum, Syd- 

 ney, labelled "Kennedy expedition," probably from Warrego 

 River district, is a somewhat close ally of 0. squamosus, Cart., 

 but may be readily distinguished by the following differences : 

 — (1) Pronotum with much wider and more horizontal margins, 

 and less thickened border (seen sideways this is round and 

 rope-like in squamosus, but thin and lamellate in kennedyi) ; 

 (2) the sharper and more produced angles of thorax; (3) 

 obovate elytra (in squamosus ovate) ; (4) much stronger sculp- 

 ture of pronotum and elytra, the former also much more 

 gibbous. Type in Australian Museum, Sydney.
