P. DB Borre (Ann. E. Belg. xiii. c.-r. p. xxix) records Haliplus striatuSf

Hydroporides. 
Schwarz (JB. schles. Ges. xlvii. pp. 190-199) enumerates 46 Silesian 
spp. of Hydroporus, giving a table of their vertical distribution. He makes 
many observations upon Thomson’s species. 
Kraatz (B. E. Z. xiv. Beih. p. GO) notes Hydroporus formosus, Aub4, 
from Andalusia, and points out its diagnostic characters, as compared with 
H. lepidus. He corrects the erroneous reference to it as a syn. of lepidus 
in Stein's Cat., and a wrong citation in Olivier’s text for the latter ] also an 
erroneous reference of H. formosus to Chevrolat by De Marseul. He gives 
Andalusia and Tangiers as localities for H. pallidas, Aub(§, and remarks 
upon the differences between that sp. and H. conjluens. 
V. Rottenbero (B. E. Z. xiv. p. 21) notes a Sicilian var. of Hydroporus 
geminus (E.), in which the yellow of the elytra predominates.
