REPORT ON MOSQUITOES. 243 



fringing the individual scale are long, as shown in figure 72, 8. 

 The anal siphon is about three times as long as broad (fig. J2, 7) 

 with a double row of toothed spines, sixteen to twenty-two in 

 each, eighteen being about the average. The teeth are small, gen- 

 erally with a large one in the middle and are confined to the basal 

 third of the spine. The ninth segment is onlv slightly longer 

 than broad, with the barred area of ten or twelve tufts of hair on 

 the ventral part and the two dorsal tufts with one long hair each. 

 The anal gills are moderately long, without obvious trachea. 



Habits of the Harly Stages. 



Larvae nearly full grown were collected on the outskirts of 

 Newark by Mn H. H. Brehme, March 28th and April 2d. The 

 first pupa appeared April 3d, the first adult on April 6th, and 

 others continued to appear until April 12th. Full grown larvae 

 and pupae were collected by Mr. Grossbeck at Morristown, May 

 1st and adults began to issue from these May 3d. In both col- 

 lections canadensis predominated and so far as our information 

 goes the habits of the earlv stages are the same in both. Col- 

 lections with larvae of that species were made also at Arlington, 

 Cranford, Elizabeth and Preakness Mountain, all in April or very 

 early May, and it is probable that throughout the more northern 

 part of the State cantans and canadensis occur together in early 

 Spring. Mr. Brakeley has never found the species at Lahawa) 

 and it does not occur there, nor anywhere in the pine belt so far 

 as we know. It cannot be considered a troublesome species from 

 present experience. 



A peculiarity of the larva is that it favors the deeper pools and 

 feeds and hides among the dead leaves covering the bottom. 

 This renders collecting rather a tedious task and makes it easy 

 to overlook them on a surface examination because they rarely 

 come to the top and do not stay there long. The pupae, however, 

 are ahvavs at the surface, as in allied forms. 



CULEX SIPHONAUS, GROSSBECK. 



The Broivn-striped Woods Mosquito. 



A species closely resembling Culex cantans but smaller, darker 

 in color and with a brown line or stripe in the center of the 

 thorax. The abdominal bands are grayer than in that species 

 and much more diffused.
