Blepharipa was proposed for the genus Sturmia of Desvoidy, owing 

 to the fact that the latter name had been previously used in botany; 

 but, according to present usage, botanical names do not interfere with 

 those employed in zoology. Ctenocnemis and Blepharipoda were pro- 

 posed to take the place of Blepharii^a, owing to the faulty construction 

 of the latter name. In the Zweif. Kais. Mus. Wien, VI, p. 213; 1893, 

 Brauer and Bergenstamm reduce Argyrophylax to the rank of a sub- 

 genus of Blepharipoda.^ All of our species have four postsutural
