The presence of an anautogenous and stenogamic population of Culex pipiens pipiens in Languedoc, France, is reported. The anautogeny was confirmed through 10 generations. A Callot morphogram corresponded to the anautogenous form. These results raise again the question of the type of relationships, genetic or ecological, of the characters classically associated with autogeny.

The Phycomycete, Coelomomyces psorophorae Couch, 1945, was found in the south of France in the salt marsh mosquito Aedes detritus (Haliday, 1833). The fungus invades the ovarioles but leaves the follicules intact. At high magnification, (using a scanning electron microscope), the crater-form punctuations adorning the sporangium were seen to result from openings (ostioles) of the network of small canals that traverse the external wall.
