The Subgenus Neoculex in America North of Mexico (Diptera, Culicidae)

Culex, subgenus Neoculex includes about twenty-five described species of mosquitoes from various sections of the world. They are distinguished by the following sum of characters: tarsi unbanded, scutal bristles strong and numerous, scales of vertex all narrow, male palpus without erect scale-like hairs on the “long” segment, male antennae without unusual processes, mesosome essentially of two lobes connected by a bridge about halfway between the base and apex. In the Nearctic species the male palpi are longer than the proboscis but in many exotic species the palpi are conspicuously shorter. The larvae are hardly separable on general characters from those of related subgenera, Mochthogenes, Lophoceraomyia and Melanoconion.
