MOSQUITOES OF THE SUBGENUS FINLAY A— KNIGHT AND MARKS 521 



Subgroup III, GANI 



Definition— Basistyle without an inner median tuft of scales. 

 Claspette filament bristlelike. Scales of ppn narrow. Sternites 

 without outstanding scales apically. 



Included species.— A. gani Bonne- Wepster. 



Group B (TERRENS-group : GUALTERIA) 



Australasian, Oriental, Palaearctic, Nearctic, and Neotropical 

 species. Wings not spotted with areas of pale scaling. Scutum with 

 In area of pale scales anteriorly (greatly reduced and fragmented in 

 unicinctus), frequently divided longitudinally down the middle by 

 a dark scaled area, a pale scaled area before the wmg base (either 

 separate from or coalesced with the anterior pale area) . Femora and 

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

 nearly their whole length. Hind tarsi with a basal and an 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 the joint between II-III or else just a 

 few basal pale scales on III, IV and V usually all dark but in a very 

 few species possessing pale markings; unicinctus offers a marked ex- 

 ception to the above in having the hind tarsi dark except for a basal 



band on I. 



In addition this group is characterized by having the general color- 

 ing black and white (not true of Subgroup VII) ; the mid- and hind- 

 femora with apical pale scaling anteriorly; larval head hairs 5 and 

 6 in a longitudinal line, hair 6 anterior to the level of 7; and the comb 

 scales numerous and in a patch (linear in lophoventralis) . The 

 larvae of cacharanus, cogilli, inquinatus, thorntoni, and tsiliensi^ are 

 not described. The larvae are usually found in tree holes, less fre- 

 quently in bamboos, and occasionally even in artificial containers in 



wooded areas. 



As Edwards (1932) has pointed out, this group has a remarkably 

 discontinuous distribution, and yet there seems to be no doubt that 

 the Neotropical species are closely related to those of the Oriental 

 region (sparsely represented in the adjoining parts of the Australasian 

 and Palaearctic regions). 



The inclusion of seoulensis in Group B is undoubtedly open to 

 question, since both the adult and larva differ in several respects from 

 all the others; yet in general habitus it seems to belong here. 



Since the male of thomtoni Dyar and Knab is unknown at present, 

 it is impossible to determine whether it belongs in SubgToup I or II.
