Genera of Culicidae. • 95 
that of the male palpi. In his definition of the genus Culex , he 
gives the £ ungues as simple. Culex pipiens is undoubtedly the 
type of that genus, and in the $ the fore and mid ungues are 
both toothed, in fact it would come, and many others of the 
genus Culex, in his genus Heteronycha. 
In the genus Taeniorhynehus Arribalzaga placed three species 
of perfectly different structure, namely, T. taeniorhynehus , Wied.,* 
T. fasciolatus, Arribalzaga, and T. confinnis, Arribalzaga. I have 
retained T. fasciolatus in this genus. 
In Ochlerotaius the characters he gives applied to two 
species I have examined, but a third, evidently closely related 
to 0. confirmatus, Arri., differed in several salient features. 
The only other genus besides Janthinosoma which seems likely 
to be of service is Uranotaenia , which he has separated from 
Aedes, the first basal cell being materially shorter than in that 
genus, the proboscis of the male having long hairs towards the 
apex and that of the female with more or less long villosity. 
Another genus has been formed by Williston for a single 
species that is found in St. Vincent, namely, Haemagogus, in 
which the palpi of £ and are five-jointed, a character by 
which the genus is at once separated from Aedes. 
The old genera that I have retained are, then, Culex , 
Anopheles, Aedes, Mochlonyx, Corethra, Megarhinus, Psorophora, 
Sahethes, Uranotaenia, and Haemagogus, and in a modified form 
Taeniorhynehus, for one of Arribalzaga’s species in that genus 
and others I have observed and Janthinosoma. 
To these I now add the following genera : Wyeomyia and 
Deinocerites (the former is separated on account of having 
chaetae on the metanotum, a character found in no other 
Culicidae, except the new genus Trichoprosopon, Deinocerites on 
account of the peculiar elongated form of the second antennal 
joint) ; Aedeomyia, separated from Aedes on account of the broad 
wing scales; Panoplites, separated from Culex on account of the 
peculiar wing scales, somewhat like those of Aedeomyia ; Eretma- 
podite , with the hind tarsi densely scaled, forming a kind of paddle¬ 
like termination ; Janthinosoma has peculiar formed head scales 
densely scaled hind legs, and a pseudo-vein running through the 
first basal cell ; Stegomyia and its sub-genus Armigeres, because 
of the curious flat-scaled or armour-like covering to the whole 
body, so strongly contrasted with the scale formation in Cidex 
proper. 
* This is Walker’s Culex titillans, my Panoplites titillans.
