that therefore my insect could not be identical with it. M. 

 Regimbart, however, is able to state definitely that G. striolatus 

 is a Macrogyrus, and therefore I am satisfied that the name I 

 have used must be regarded as a synonym. 



DINEUTES. 



D. rufipes, Fab. Dr. Regimbart thinks I am probably right 

 in believing this to be the same species as D. australis, Fab. 



PALPICORNES. 



CERCYON. 



C. nigriceps, Marsh. Among some Coleoptera collected by 

 Mr. P. Morris in the neighbourhood of Adelaide, and also among 

 some specimens collected by Mr. Dodd near Townsville 

 (Queensland), I have found a Cercyon which I cannot separate 

 from this common European species. No doubt it has been 

 introduced.

Only three Australian Quedii of the section with the head 



elongate and narrow have been previously described. From 



them the present species differs by its very small and short elytra 



(under which I feel sure there are no wings, but as the type is 



unique and in extremely good condition I am unwilling to risk 



damage by investigation). Apart from this character the species 



is very distinct from its allies by the following (among other) 



characters : — From ceneus, FvL, by its very different color and 



size, and the very sparse puncturation of the hind part of its 



abdomen ; from cuprinns, Fvl., by its very different size and 



color (e.g. the apical two joints of its antennje testaceous, its elytra 



bicolorous) and (if I have rightly identified cuprinus) its elytra 



more finely punctulate and antennae notably more slender ; from
