In the 1920 catalogue, 2789, 2790, 2791 

 were placed in Hydrous, following Zim- 

 mermann. The researches of Mr. Mutchler 

 indicate that this was an error. See 3rd

brathinid;e 



The genus Brathinus, following Casey is associated with Omaliinse 

 by Bradley 30-64; Forbes 26-67 and 26-113 found resemblance in wing 

 folding to Scaphidiidae and retained the family name. The larva is 

 still unknown. 



• According to larval characters, Helophorus and Hydrochus must be ranked as families of 

 Hydrophiloidea. By the larval characters also, Limnebius, Ochthebius and Hydraena are removed 

 from Hydrophilidae to form a family Limnebiidse in Staphylinoidea.
