MOSQUITOES OF THE SUBGENUS FINLAYA— KNIGHT AND MARKS 535 



Discussion.— This subgroup is particularly distinct from all the 

 other subgroups of Group F in the nature of the scutal scaling and 

 in the arrangement of the larval head hairs. Some specimens of 

 aJticola may go to Subgroup VI and possibly the species is even in- 

 termediate between Subgroups II and VI. The position of this 

 species will remain uncertain until the male and larva are described. 

 King and Hoog.straal (1046) treat this subgroup in detail. 



Subgroup III, SIMLENSIS 



Definition.— Oriental. Basistyle without a tuft of specialized scales 

 (male of simlcmis is undescribed) . Claspette filanu^nt bladelike. Male 

 palpi as in Subgroup I. Female tori scaled medially. Vertex dorsum 

 broad scaled (may be narrow scales along ocular margin and on nape) . 

 Scutal scaling not as in Subgroup II. Ppn with at least some narrow 

 scales. Postspiracular area not scaled. Paratergite without scales, 

 a few present in simlemis, however. Neither femora nor tibiae 

 sprinkled with pale scales anteriorly. Hind tarsi with first three to 

 four segments with basal white bands, sometimes a very few apical 

 white scales on one or more segments. 



Supplementary characters.— '^owieWwm with narrow scales. Sub- 

 spiracular area with or without scales. Preala scaled below laiob. 

 Type of larval head hairs widely different in alhocinctus and gillh 

 being well developed and branched in first, and with 5 and 6 very long 

 and*single in latter (the larva of simlensis is undescribed). Comb 

 teeth numerous, in a patch. Larval habitat : tree holes. 



Included species.— A. alhocmctus (Barraud), gilH (Barraud), and 

 simlensis Edwards. 



D;scussioii.—Oi\ the basis of the larval difference mentioned above, 

 it is believed that this is not a natural subgroup. The adults of this 

 subgroup can be separated from those of Subgroup I only on the 

 absence of a tuft of modified scales on the basistyle. For a compre- 

 hensive discussion of the species included here, see Barraud (1934). 



Subgroup IV. PURPUREUS (Molpemyia) 



Z>e;?m^?:on.— Australasian. Basistyle without a tuft of specialized 

 scales. Claspette filament bladelike in lateral view. Male palpi as 

 in Subgroup I. Female tori with dark hairs medially (in some speci- 

 mens of aundormm there are a few small flat dark scales here) . Ver- 

 tex dorsum with narrow scales. Scutal scaling not as in Subgroup 

 II. Postspiracular area bare. Paratergite scaled. Neither femora 

 nor tibiae sprinkled with pale scales anteriorly. Hind tarsi with 

 basal bands on I-III, rarely on IV; V sometimes pale in aundorsum. 



Supplementary ^'/m/w/tv-s-.— Scutellum with narrow scales. Sub- 

 spiracular area with or without scales. Preala scaled below knob.
