Saida morio (Zett.) and S. Jlori (Dohrn) are described as Biitish by

HYDROMETRIDiE. 
The species belonging to this group are referred by StSl (Hem. Afr. iii.) 
to the 3 families Hydrometrida, Veliida, and Hydrobatida, the first two in- 
cluding each a single African species; the third 2 species belonging to StSl’s 
genus Tenagog&nus. 
Mayr (Beise der Novara, Zool. ii. Hem. p. 169) tabulates the genera of 
Hydrometridce known to him; including the three new genera proposed by 
him in 1866. He also fully describes these new genera and the species of 
which he gave diagnoses at the same time, and figures the following : — 
Hydrometra pectoralisy Taf. 6. fig. 60; II. 7iitida,^g. 61; Limnometra inermis, 
fig. 63 ; X. minuta, fig. 64 ; Brachymetra (Halob.) albmervus (A. & S.), fig.
