GENUS UNCERTAIN 



Culex impudicus, Ficalbi, Bull. Soc. Ent. Ital. p. igo (1890) (Sardinia, Sicily). 



Probably comes in Grabhamia.

22. Genus ACARTOMYIA, Theobald 



Acartomyia, Theobald, Mon. Culic. Vol. 3, p. 25i (igo3). 



Characters. — Allied closely to Grabhamia but differs in cephalic ornamentation. Head clothed 

 with irregularly disposed flat scales all over, with patches of narrow curved and numerous upright 

 forked scales, giving the head a general ragged appearance. Thorax with narrow-curved scales. Palpi of 

 9 composed of 4 segments, of the of much swollen apically involving the last two segments and the 

 apex of the antepenultimate segment, the apical one being especially swollen. Wings with rather small 

 fork-cells, majority of vein scales broadish and with crenulated edges,, mottled. 



Larvae with short thick siphons when mature. 



Geographical distribution of species. — A single species only occurs at present; the larvae 

 living in salt pans along the shore at Malta. This mosquito may have some connection with Mediter- 

 ranean fever.

23. Genus LUTZIA, Theobald 



Lutzia, Theobald, Mon. Culic. Vol. 3, p. i55 (igo3). 



Characters. — Head scales of all three forms, narrow-curved, upright forked and flat lateral 

 ones; scales of thorax narrow-curved. Wings with partly Culex-like and partly T<zniorhynchus-\\ke scales, 

 the latter forming dark areas and spots; wing fringe spotted. Palpi of 9 composed of 3 segments; cf 

 palpi of 3 segments, the last segment acuminate slightly longer than the penultimate, all the segments 

 very hairy, except at the base of the palpi. 



Geographical distribution of species. — A single species only is known in the genus 

 coming from South America. It can easily be told by its large size and spotted wings.

24. Genus GULEX, Linn>eus 



Culex, Linnaeus, S3 r st. Nat. (1735). 



Characters. — Head clothed with narrow-curved and upright forked scales and with flat scales 

 at the sides. Thorax with narrow-curved and curved hair-like scales on both mesonotum and scutellum. 

 Abdomen with flat scales all over. Legs simple and scaled. Ungues of 9 equal, simple or serrated; of 0* 

 in fore and mid legs unequal, simple or serrated. Wings with the fork-cell long or moderately long, the 

 lateral vein scales linear or slightly lanceolate. Palpi of (f acuminate. 



This genus, the type of the family still contains a number of species that may possibly be justifiably 

 excluded from it.
