GENUS CULEX 391 



boscis, subulate, strongly tufted, mainly yellow, but darker in the middle 

 of the joints. Antennae of $ , nearly as long as proboscis. Pleurae 

 marbled with yellow, brown and white ; scutellum pale ; ventral seg- 

 ments pale witli dark hinder borders. Length. — 8 or 9 mm. 



Habitat. — Mexico, Brazil. 



Note. — This is one of the largest and certainly the handsomest of all 

 mosquitoes and can hardly be mistaken, unless indeed one chances to 

 have read the original description. 



3. CULEX HYRCANUS, Pallas. 



(Reiseu durch das Russisch. Reich. (1771).) 



A grey species, rather hirsute, with a fuscous line down the 

 abdomen ; wings with black spots along the costal margin. 

 Described by Pallas in 1771. Found near the Caspian Sea ; not 

 since recorded. In company with G. Caspiiis (Pallas), but less 

 common and vicious. 



Nothing corresponding to this inadequate description has come to 

 hand at the Museum.
