In the Annales Soc., Ent. de France, LXIX., p. 171, P. Marchal publishes an article entitled “Sur un nouvel Hyménoptère aquatique, le Limnodytes gerriphagus, n.gen., n. sp.”

Mr. Marchal is to be complimented on his discovery and observation of the habits of this very interesting insect, but it is deeply to be regretted that the generic name which he has chosen is preoccupied, hence it becomes widely known. The name Limnodytes was employed by Dumeril and Bibron in their “Erpétologie généralem“ Vol. VUUU., 1841, p.510, for a genus of salamanders, hence I propose in its place the term Tiphodytes, nov. name.
