STEGOMYIA 



The legs are uniformly clothed with flat scales in this genus, 

 while those of the head and scutellar space are broad and flat. 

 The third longitudinal wing vein is not usually continued into 

 the basal cell as in Culex. 



Stegomyia signifer Coq. 



This species is very similar to C u 1 e x f a s c i a t u s Fabr., 

 but may be distinguished from it, according to Coquillett, by the 

 simple tarsal claws, that is, without teeith, and by the tarsal 

 joints being banded at both ends. This is the only species of the 

 genus liable to occur in the State. It has been taken in New 

 Jersey. 



Description. The larva is abnormal for this genus, according to 

 Dr Dyar. He states that the peculiar dorsal platings at the end 

 of the body occur also in Corethrella brakeleyi, but 

 not in any other culicid that he has seen. The short antennae 

 and the elongate head suggest Uranotaenia and Anoph- 

 eles. 



Larva. The following characteiristics are from Dr Dyar's 



description : 



Head, rounded, elliptic, slightly flattened, black; antennae 

 very short, small tuft before the middle; eyes, black, transverse; 

 seventh abdominal segment with a round, dorsal plate, incised 

 anteriorly. An angulated transverse plate on the eighth segment 

 anteriorly, reaching below the middle of the sides, with the comb 

 at its posterior border but not united with it. The comb consists of 

 long scales in a transverse row and a shorter second row, finely 

 divided on the side next to the body. Air tube is about three times 

 as long as wide, slender, rather small, without pecten but with a 

 hair tuft beyond the middle; a small, linear, transverse, lateral 

 plate on the last segment anteriorly ; segment trigonate, ringed by 

 its plate ; tuft and brush normal, the latter confined to the barred 

 area ; no anal processes visible. 



This species was described by Coquillett from the District of 

 Columbia and British North America, and it has also been taken 

 in New Jersey. Dr Smith states that the larva occurs in some- 

 what foul water, and that it may be recognized by its robust build
