Genus SericophorUS, Sm. 



This genus is distinguished from Sphodrotes by the appen- 

 diculate radial cell, by the pointed, not petiolate, second 

 cubital cell, by the absence of coarse puncturation, by the 

 shorter and more or less clavate anteniue, and by the more 

 conical form of the abdomen, also by the twelve-jointed 

 antennge of the male. From Zoyphium it can only be distin- 

 guished by the appendiculate radial cell^ and it is very 

 doubtful if the two can be permanently retained as separate 

 genera. The very large pulvillus also distinguishes both of 

 these Irom Sphudrotes. 



The genus is confined to Australia. 



Type of the genus, *S'. cha/f/lneus, Sm. 



In his description of this genus (' Uattungen der Sphe- 

 giden,' p. 385) Kohl says " Tubercula humeralia alarum 

 teguias attingunt." This is a mistake; probably " non " 

 has been accidentally omitted.
