* Bergroth {Mem. Soc. Ent. Belg., XXII, p. 179, 191.3), on the strength of Distant's description 

 and figure, erected a new genus Auchenophis for Metacanthus hihamatus Dist., recorded from 

 Ceylon. Bergroth's description, apparently based on Distant's inaccurate figure (Entomologist, xliv, 

 p. 105, 1911), is misleading. The first rostral segment does not extend beyond the base of the 

 head. Auchenophis is, in fact, synonymous with Protacanthus Uhler, Distant's species being 

 generically identical with the type of Protacanthus decorus Uhler, now preserved in the British 

 Museum Collection.
