618 A Monograph of Culicidae. 



Legs unhanded, with metallic bronze and purple hues ; spiny. 



Wings with broad, elongate, asymmetrical brown scales, 

 violet at the base of the wings ; fork-cells long ; the first sub- 

 marginal much longer and narrower than the second posterior 

 cell, their bases level, stem of the former about one-fourth the 

 length of the cell, of the latter one-half the length of the cell ; 

 supernumerary and mid cross-veins, meeting at an angle; the 

 posterior a little nearer the base than the others. 



Length. — 4 mm. 



Habitat. — Rio de Janeiro (Prof. Goeldi). 



Observations. — Very near Sabeihoides confusus, Theobald, but 

 differs in having the head purple and in the purple and silvery 

 white abdomen. 



Genus SABETHINUS. Lutz (1904). 



Sabettinus. Lutz (Blanchard) (1905). 



Mosquitos do Bresil, pp.48 and 57 (1904); Les Moust., p. 634 (1905), 



Blanchard. 



Head clothed with flat scales all over. Thorax with irregular 

 flat scales, which become large behind and over the scutellum 

 where they are more definite in arrangement ; metanotum with 

 chaetae and squamae. Proboscis rather short, dilated at the 

 apex. Wings with large scales ending asymmetrically ; fork -cells 

 long in 9 t shorter in $ ; cross-veins close together, the mid 

 slightly nearer the apex. Antennae of J pilose, of £ rather 

 more so. Genitalia very marked, with broad chaetae at the base 

 on each side, long claspers ending in a broad plate with one side 

 prominently fimbriated. 



This genus comes very near Sabeihoides, Theob., in fact it can 

 only be separated by the proboscis being swollen apically, unless 

 there is marked genitalic diversity. 



Three species occur which may be tabulated as follows : — 



Chaetae at base of wings jet black. 



Thorax metallic green intermedins. Lutz. 



Thorax metallic deep blue albiprivatus. Lutz. 



Chaetae at base of wings light golden-brown aurescens. Lutz.
