Genus Anopheles. 31 



edge and six long hairs ; colour dark brown, pale yellow at base, 

 surface set with rather large spines ; the 4-branched hair larger 

 and situated one-third the length of antenna from the base. 

 Mandible and maxillary palpus of normal Anopheles form, the 

 former with four instead of three curved spines, three of them 

 feathered on one side ; the latter with the two apical processes 

 spatulate in form. Lateral combs consist each of a large plate, 

 the posterior edge with seven or eight long stiff spines and with 

 10-12 shorter spines between them. The ninth segment rather 

 stout, dorsal tufts and ventral fan as in others, with the dorsal 

 plate a little larger. Tracheal gills short and stout, less than 

 half the length of the other two species." 



Note. — Unfortunately no mention is made of either frontal 

 hairs or palmate hairs. 



Synonomy. — Wiedemann's ferrugineus is said by Coquillett to 

 be the same as Say's quinquefasciatus, and both are synonymous 

 with Culex pipiens. It was at one time thought to be synonymous 

 with Anopheles crucians.
