Genus Aedcs.

trace of a third joint. I cannot find more than two joints, but 
there is a basal notch which might be mistaken for a joint. 
The characters given by Arribalzaga and Skuse do not apply 
to the genus Aedes as intended by Meigen, who described only 
one species originally, namely, Aedes cinereus ; both Arribalzaga’s 
Aedes squammipennis and Skuse’s Aedes venustipes being quite 
different types of insects from the European Aedes, and hence 
I have separated them and formed the genus Aedeomyia. 
Meigen’s description* of the genus is as follows :— 
“Antennae porrectae, filiformes, 14-articulatae ; maris plu- 
mosae, feminae pilosae. Proboscis porrecta, longitudine thoracis. 
Palpi brevissimi. Alae squamatae, incumbentes.” 
Ficalbi, who has added most to our recent knowledge of this 
family, adds little of value to Meigen’s characters for universal 
species. 
Life-history of Aedes. —Little or nothing is known of the 
metamorphosis of the members of this genus. Osten-Sacken 
bred Aedes fuscus , but gave us no information as to the larvae, 
&c., except the wide statement that they present a general 
resemblance to those of Culex. 
It appears that neither the £ nor 9 attacks animals or man, 
as a rule, at least no mention has been made of them doing so 
in any communications received with the collections that have 
been sent from abroad. 
With regard to our European species, Ficalbi states that 
they do not attack man or mammals. 
From the numbers received from E. M. Walker, from Ontario, 
I should judge, however, that they are more or less troublesome, 
but no note was sent to that effect. Ae. Butleri is said to be 
troublesome in the Malay Peninsula. 
Very few species have been received in the collections. Four 
new species have been received, which I should unhesitatingly 
have placed as three Culex, had the scale structure not been 
examined; but all four {Ae. Butleri, Ae. nigricorpus, Ae. nigra, 
and Ae. Pembaens's ) have broad scaled heads and narrow scaled 
scutellum, which we find in this genus. No males of them 
have been received ; but the scale structure shows them to belong 
here, and separates them from the Stegomyia3.
