Species of Garenum omitted from the list above, because no 

 specimen has been available for reference, and their position seems 

 doubtful : — 



G. perplexu7n. White, seems a very isolated species; I doubt if it 

 is very closely allied to G. Icevipe7ine, Macl. 



PlatytJiorax interioris, SI., seems to oflfer affinities to both the 

 G. disjjar and 6^. tra7isversicolle groups. 



* C. subcostatum seems more naturally placed in the G. marginatum 

 group than anywhere else ; sometimes the diseoidai punctures of the elytra 

 are present.
