NEW AMERICAN MOSQUITOES.

 Washington, D. C. 



Culex agitator, new name. 



We propose this name to replace Mochlostyrax ciibensis Dyar & 

 Knab, since when this species is transferred to Culex, as will follow 

 from Mochlostyrax not being separable from Culex in the adult state, 

 it is preoccupied by Culex cubensis Bigot, 



Culex ochropus, new species. 



Dark brown, the head and thorax rather sparsely clothed with 

 light yellow scales and brownish bristles, not forming any distinct or- 

 namentation, but contrasting with the brown membrane below ; abdo- 

 men clothed with pale testaceous scales, unhanded. Legs pale testa- 

 ceous, the ends of the joints, as well as the ends of the proboscis and 

 palpi brownish. Wing scales pale brown, dense. Claws simple.
