of the o' antennae, both evidently uncertain quantities in many 

 cases. 



The following table attempts to elucidate the few genera that 

 appear well founded, but their validity, of course, depends on the 

 definite nature and constancy of the points tabulated, and it is 

 seen that practically nothing but palpal characters can be used. 

 The other recorded genera appear of uncertain validity.

Generic notes on the Aedes group. 



Haemagogus, Will. By the 5-jointed palpi in cf and 5 this 

 should be a good genus, though the ist and 5th joints are very 

 small. Colonemyia, Leices., may be synonymous as it is also said 

 (with a doubt) to possess s-jointed palpi. 



Zeugnomyia, Leices. Palpi in cf 3, in 2 4-jointed. On this 

 it cannot be synonymous with either Aedes or Skusea. Its author 

 says it is allied to Colonemyia, Skeiromyia and Uranotaenia, and 

 through these to the Wyeomyia group. P"or my own part I leave 

 its position in abeyance at present. 



Skusea, Theob. Of its 3-jointed palpi in both sexes, the last 

 is " small and ripple-like," and on this it is tentatively ranked as 

 valid, at least pro. tern. There seems nothing to separate Aiore- 

 tomyia, Leices., and Acalleomyia, Leices., from Skusea. 



Aedes, Mg. Technically with 2-jointed cf and 4-jointed $ 

 palpi, this genus is sufficiently distinct from Culex, but several 

 others must be included as identical, disMicraedes, Coq., Aedeomyia, 

 Theob. , A edinus , Lutz. , and probably both Leptosomatomyia, Theob. 

 (established on a unique of), and Squamomyia, Theob. (of which 

 the 9 is unknown). 



Uranotaenia, Arrib. Apparently a natural group whether 

 of generic rank or not, characterized by 2-jointed palpi in cf and ? , 

 a proboscis swollen at the tip, the usually quite small size and often 

 brilliant blue colouring. Pseudouraiwtaenia, Theob., Anisochclc- 

 omyia, Theob., Verrallina, Theob. (in which trace of an additional 

 basal palpal joint is spoken of in the 9 , the cf being unknown), 

 and Ficalbia, Theob., are evidently synonyms. 



Hodgesia, Theob. The cf is unknown, which is unsatisfac- 

 tory. The 9 antenna is reputed to have only 13-joints. which
