Class ijia.it ion of the Culicidii'. 245 



one species {='^ Lophoscelonit/ia^^), in whicli tiie terminal 

 segment and genital lobes are covered with narrow scales. 

 Wings very dark, though not without spots; their front edge 

 never has more than two .s|)ot3 (i-xclusive of a spot which 

 may be present in the tringe at the tip of the wing), which 

 are tisually small. Wing-scales usually rather broadly 

 elliptical. Palpi always shaggy with scales. 



One species is Palrearctic and one is Australian ; the others 

 are Oriental and Ethiopian. 



c. Subgenus Curistya, Theobald. 



Differs from Myzorhynchus chiefly in having an outstanding 

 wisp of stiff, slender, extremely long scales on either side of 

 every segment of the abdomen. In addition to these peculiar 

 lateral scales there are some ordinary narrow scales on the 

 genital lobes and last segment of the abdomen. 



One species, found in Eastern Africa. 



d. Subgenus Arribalzagia, Theobald. 



(luchuling Arribalzagia, Manr/iiinhosia, Kerteszia, and part of 

 Cyclolepidojpteron of Theobald's Monograph.) 



There may be some narrow scales on the pronotum and 

 front of the scutum, but the vestiture of the scutum consists 

 mainly of hairs. Conspicuous broad scales are present 

 (scattered) on some or all of the segments of the abdomen, 

 and often stand out as prominent tufts or broken bands. The 

 wings, though spotted, have a dark cast, owing to predomi- 

 nance of blackish scales, and in several of the species there 

 are large black spots 0!i the front edge, the colour of which, 

 though mainly due to broad scales, is partly due to staining 

 of the wing-membrane itself. Wing- scales broad. Palpi 

 shaggy with scales. 



Kestricted to the Neotropical region. 



c. Subgenus Myzomyia, Blanchard. 



(Including Mi/zomj/ia, Feltinella, Neomyzomyia, and Pyretophorus of 

 Theobald's Monograph, and Nyssomyzomyia of James.) 



There may be some distinct scales on the pronotum and 

 adjacent part of the scutum, but the main vestiture of the 

 scutum consists of hairs or of narrow scales. There may be 

 a few narrow scales on the genital lobes, or even — few, 

 scattered, and inconspicuous — on the terminal segment of the 

 abdomen, but the main vestiture of the abdomen consists of 

 liairs. The wings are almost always profusely spotted, and
