MOSQUITOES OF THE SUBGENUS FINLAYA — ^KNIGHT AND MARKS 539 



Supplementary characters— ^cui^Wd^r scales narrow. Subspiracu- 

 lar area scaled. Preala scaled below knob. Larval head-hair ar- 

 rangement not described. Comb scales in a line. Larval habitat: 

 bamboo stumps. 



Inclvded species. — A. fengi Edwards. 



Discussion.— T\\\s species shows some relationship to miicinctus in 

 Group B. 



Group H (GENICULATUS-group: PROTOMACLEAYA) 



Australasian, Oriental, Palaearctic, Neotropical, and Nearctic 

 species. Wings not spotted with areas of pale scaling. Scutal mark- 

 ings various, but not consisting largely of a pattern of longitudinal 

 pale lines (except in eatoni where it is entirely of lines except for a 

 small patch before wing base) , nor as in Group B. Femora and tibiae 

 not spotted and ringed, nor lined anteriorly with pale scales for nearly 

 their whole length. Tarsi completely dark. 



In the absence of specimens or additional descriptive information, 

 it has not been possible to assign either peipingensis Feng or ywi- 

 nanensis (Gaschen) to subgroups. 



This group includes all of the dark-legged Finlaya species known 

 except the two Madagascar species monetus and pMllipi (which on 

 general relationships are placed in Group C in this paper) .
