MOSQUITOES OF THE SUBGENUS FINLAYA— KNIGHT AND MARKS 519 

 KEY TO THE GROUPS OF THE SUBGENUS FINLAYA 



1 Wings profusely spotted with areas of pale and dark scaling; femora and 



tibiae spotted and ringed with pale scaling for nearly their whole length 



Group A (kochi-group) (p. 519) 

 Wings not spotted; 2 femora and tibiae not spotted and ringed with pale scal- 

 ing for nearly their whole length 



2 Hind tarsi with a broad white band at base of II, usually also a narrower 



ring at base of I, remainder of segments dark, or V all white except possibly 

 for one side « (III basally banded in embuensis) ; Ethiopian and Madagas- 



caran species -_Group C (longipalpia-group) (p. 525) 



Hind tarsi not marked as described above WV^i^ 



3. Hind tarsi all dark scaled Group H (geniculatus-group) (p. 539) 



Hind tarsi with pale markings '"' V" V V-* 



4 Scutal pattern consisting of a pattern of narrow longitudmal Imes of white 



to yellow scales (in addition, there may be 1 or 3 small pale areas on an- 

 terior margin, a patch on posterior margin of anterior fossa, and a small 



patch before wing base) yj"-, ,' " * 



Scutal markings various in type, or absent, but not consisting largely of a 

 pattern of narrow longitudinal pale lines * :,.""'.", 



5 At least the mid-femora, and usually also one or more of the tibiae, hned 



anteriorly with pale scales for nearly their whole length, occasionally 

 femoral line broken and no anterior pale tibial line present. 



Group E (mediovittatus-group) (p. 530) 



Femora and tibiae not lined anteriorly with pale scales for nearly their whole 



J tjj Group D (aureo8triatu8-group)Mp. 52b) 



6 Hind tarsVwith a'basal and apical band on I (rarely no basal pale scales on I), 



a basal band on II (this usually about equal in size to the apical marking 

 on I), sometimes pale scaling is present over joint between II and 111 or 

 else just a few basal pale scales on III, IV and V usually all dark but m a 

 few species possessing pale markings; in Subgroup IV the hind tarsi are 



dark except for a basal band on I Group B (terrens- group) (p. 521) 



Hind tarsi with basal bands on at least the first three segments (if only on 

 the first two then no apical bands present); sometimes one or more seg- 

 ments with a small amount of apical pale scaling but not with definite 

 l^a„(jg Group F (alboannulatus-group) (p. 532) 



Group A (KOCHI-group: FINLAYA, s. str.) 



Australasian and Oriental species. Wings profusely spotted with 

 areas of pale and dark scaling. Scutum with a definite or indefinite 

 variegated pattern of dark and pale scales. Femora and tibiae 

 spotted and ringed with pale scaling for nearly their whole length. 

 Hind tarsi variously banded or marked with pale scales. 



« May be a small basal area of pale scaling however. Also, monocellatui and biocdlatus of Subgroup VIII 

 Group F, have one and two large anterior areas of pale scales respectively. ^ , . n 



. The Madagascar species monetus and phillipi, although obviously members of Group C, key to Group 

 H because of the all-dark hind tarsi. „„„»„^ K„f oUn 



. The Oriental species albotainiatu, var. mikiranus has three indistmct pale Imes on the scutum, but also 

 nosse<!.sps a lareo white area before the wing base. 



'Tsome iiduals of a few species of Subgroups IV, V. and VI of Group D will key to Group F owmg 

 to the linear scutal pattern being obscured by general pale scaling, or to its becommg obsolete altogether^ 

 Some individuals of Quasirmthorax have a fairly definite anterior line on the m.dt.bm and a less definite 

 line on midfemur and thus would key to Group E.
