taken together shorter than the one preceding, in the male long 

 haired; antennae 15 jointed, the basal joint disklike, the follow- 

 ing ones small, in the male long haired, in the female short and 

 sparsely haired; eyes somewhat reniform, the ocelli wanting^ 

 the mesothorax rather long and somew^hat pointed in front, and 

 without transverse suture; scutellum narrow, the metathorax 

 rather prominent; abdomen long and slender, eight jointed, the 

 genitalia small and inconspicuous; legs long and slender, nearly 

 bare; wings with the veins and the margin thickly haired, the 

 venation as in the figure. 



The females may be easily distinguished from Culex by the 

 presence of palpi about as long as the proboscis; the male may 

 be distinguished by the following characters. In Anopheles the 

 last two palpal joints are much thicker than the first and second^ 

 and spatulate in form, while in Culex they are the same in diam- 

 eter, the last one more or less pointed; further, in all the species 

 which I have examined, a stump of a vein extends back into the 

 basal cell from the base of the radial sector and another from 

 base of R4+5; this venation seems to be rare in Culex; in our 

 species also the fourth tarsal joint of the fore leg in Anopheles 

 is more than twice as long as wide, while in Culex it is no longer 



than wide.
