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 preseut usage, botanical names do not interfere with 
those employed in zoology. Ctenocnemis and Blepharipoda were pro- 
posed to take the place of Blepharipa, 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 
macrochete :

Blepharopoda Rondani, Nuovi Annali Sci. Nat. Bologna, Ser. 3, Vol. II, p. 862; 1851, 
and on page 92 of the same work the genus Ctenocnemis of Kowarz is, on the authority 
ot Mr. Verrall, made synonymous with Blepharopoda. The writer has been unable 
to consult the above-mentioned paper by Rondani, but if Mr. Verrall’s reference is 
correct, the name of and reference to Blepharopoda Rond. should be inserted imme- 
diately after Sturmia in the above list of synonyms.
