27. Genus MELANOCONION, Theobald 



Melanoconion, Theobald, Mon. Culic. Vol. 3, p. 238 (1903). 



Characters. — Head clothed with narrow-curved scales and upright forked ones, the latter pre- 

 dominating. Thorax and scutellum with narrow-curved scales. Palpi short in the 9 > lon g i n cf • Proboscis 

 expanded apically. Wings with the veins covered with small dense broad flat scales at their apical 

 portions and along the costal border, which has on its upper side spine-like scales. Femora swollen at the 

 apex and base, tibia? swollen at their apices. 



Mostly small black gnats which bite viciously and which swarm in swamps and forests. 



They are easily told from Culex by the form of the wing scales on the apical half of the wing. 



Geographical distribution of species. — The six members of this genus occur in Asia, 

 Afiica, South America and the West Indes.

28. Genus LASIOCONOPS, Theobald 



Lasioconops, Theobald, Mon. Culic. Vol. 3, p. 235 (1903). 



Characters. — Head clothed with similar scales to Culex. Thorax with narrow-curved scales. 

 Abdomen clothed with flat scales and with large projecting flat lateral scales with deeply dentate apices, in more 

 or less dense tufts. Wings with typical Culex scales and venation. Palpi short in the 9 • 



This genus is separated from Culex on account of the very peculiar abdominal scales. 



Geographical distribution of species. — A single species only known in the 9 sex - 

 1. L. poicilipes, Theobald, Mon. Culic. Vol. 3, p. 236 (igo3) (Bonny, Gambia). 



28. Genus FINLAYA, Theobald 



Finlaya, Theobald, Mon. Culic. Vol. 3, p. 281 (igo3). 



Characters. — Head clothed with flat scales, broad curved scales and numerous upright forked 

 ones and with long projecting bristles in front; the broad curved ones border the eyes and form a median 

 area, the flat ones are much rounded apically and not so closely applied to the surface as in Stegomyia. 

 Mesothorax with narrow-curved scales. Scutellum with flat scales, somewhat rounded apically and 

 narrow-curved ones form a basal row; prothoracic lobes with flat scales. Abdomen clothed with flat 

 scales, the apical segments with ventral scaly tufts. Palpi of 9 short, densely scaly, of 4 segments (?) in
