and the wings are not spotted as a rule. The few species in which 

 they are maculate are reco'gnizable by their small size, even with- 

 out reference to the generic characters. When at rest, the body 

 is held parallel tO' the surface, and the legs, though pointed up- 

 ward, are not elevated nearly so high as in Anopheles. 



The species here referred tO' Culex have been distributed 

 among a . number of subdivisions on various characters which 

 are not readily seen without a compound microscope. I there- 

 fore leave them together here, but in the list of species refer them 

 tO' their proper divisions, though I am not at all sure that these 

 are correct associations in all cases. 



3. Janthinosovna, in which the palpi of the male are very long 

 and those of the female short ; the disproportion in the sexes much 

 greater than in Culex, which the genus otherwise resembles. The 

 abdomen is more or less purple and the hind legs are black with 

 the feet white. The resting position is as in Ctdex. 



4. Psorophora contains the giant among our mosquitoes, rec- 

 ognizable not only by its size but by the erect scales on the legs, 

 giving them the appearance of chimney cleaners on a small scale. 

 The antennae are rather short in both sexes. The palpi, or mouth 

 feelers are long in the male, short in the female, and the position 

 when at rest approximates that of Culex. 



5. Aedes, in which the palpi, or mouth feelers, are short in 

 both sexes ; but the characters are otherwise much as in Ctdex, 

 though the size is smaller. 



6. Uranotcunia, in which the palpi, or mouth feelers, are short 

 in both sexes, the proboscis is swollen at the apex, and the thorax 

 is ornamented with metallic blue scales. 



7. Wyeomyia, in which the palpi, or mouth feelers, are short 

 in both sexes and the proboscis is two-thirds the length of the 

 body. The species is even smaller and slighter than Aedes, and 

 when at rest the legs are held high in the air curved over the 

 body and the tarsi recurved toward the head. 



The three genera Aedes, Uranotcunia and Wyeomyia each con- 

 tain only one small species of a somewhat distinctive appearance, 

 and, indeed, only Anopheles and Cidex really have more than a 

 single representative in our State. 



The Corefhrini, or short billed mosquitoes, that occur in New 

 Jersey represent three genera. 



1. Sayomyia, in which the palpi, or mouth feelers, are short 

 in both sexes; the antennae are somewhat beaded with whorls of 

 hair tO' each joint, and the first joint of the tarsus, or foot, is 

 longer than the second. 



2. Corethra, in which the palpi and antennae are as before, but
