MOSQUITOS OR CULICIDAE OF NEW YORK STATE 339 



and rather sickly white thorax, contrasting with the darker 

 abdominal segments. The antennae differ from those of either 

 Culex or Stegomyia, and the anal siphon has no rows of spines 

 or teeth.

This species may be identified by the large elongate, oval, 

 lanceolate, lateral scales of the wing veins. This mosquito is the 

 only one of the genus occurring in the State, and it has previously 

 been referred largely to the genus Culex. Dr Howard has listed 

 this species from a number of localities in the United States and 

 from Porto Rico and Cuba. It is probably widely distributed 

 south of Canada. Its peculiar scales are illustrated on plate 26, 

 figure 3. 



This subfamily contains those mosquitos having very short 

 palpi in both sexes. There are two genera, both of which have 

 been found in New York State. The first, Aedes, is nonmetallic, 

 while the second, Uranotaenia, has metalliclike stripes of flat 

 scales on the thorax.

This mosquito may be recognized by its basal abdominal cross 

 bands of cream-oolbred scales. The larva was met with in early 

 spring at Nassau and Karner -where it was associated with 

 Culex cinereoborealis, C. canadensis, C. can- 

 tans and C. i m p i g e r. We have also taken it at Pough- 

 keepsie. Dr Dyar reports taking it in company with C. cana- 

 densis and C. sylvestris, and adds, that like them, it 

 possesses a short breathing tube.
