REPORT ON MOSQUITOES. 231 



is rather long, broadest in the mickhe, with a small apical spine 

 and lateral ones, becoming- very small basally. The anal siphon 

 is yellowish brown, abont three and one-half times as long as 

 broad, with- the lateral rows of spines fifteen to seventeen in 

 number, extending about half the length of the siphon from the 

 base; the single spines are broad at the base with one large 

 tooth, or with one or two smaller ones beside the large tooth 

 (fig. 68, 9). The ninth segment is almost square, largely cov- 

 ered by the chitinized saddle; the double dorsal tuft and ventral 

 brush are moderate, the latter with two small tufts below the 

 barred area. The anal gills are one and one-half times as long 

 as the ninth seginent. 



Habits of the Early Stages. 



This seems to be one of the spring species, the larvae being 

 taken by Mr. Grossbeck May 9th and 14th in rocky pools on 

 Garrett Mountain, near Paterson. On the 9th a mixture of 

 larvae and pupje were taken, the larvae being recognized as chiefly 

 canadensis, a few sylvestris and one mature specimen recognized 

 as theretofore unknown. May 12th a new species, niveitarsis, 

 emerged from one of the pupae, it was recognized as theretofore 

 undescribed and the larva was put in alcohol. On the 14th 

 another search turned out five additional larvae of the new species, 

 together with larvae and pupae, mostly canadensis, many sylves- 

 tris and a few Aedes fuse us. Two of the new larvae were pre- 

 served in alcohol and the other three fell prey to some small 

 Dytiscids which had been overlooked in the bottom material. 

 One of the pupae developed a C. niveitarsis and made the type 

 pair from which Mr. Coquillett described the species. Persistent 

 collecting later in the season failed to turn out additional material 

 in this species. 



CULEX CANTATOR, COQ. 



The Brozvn Salt Marsh Mosquito. 



This is a rather large, robust brown mosquito, in which the 

 thorax is rather well covered with distinct spiny hair. The beak 

 is not banded, the wings are not spotted, the tarsi are banded with 

 white or whitish at the base of each joint, but the bands are not 

 well marked and the merger into the ground color is gradual. 

 The abdomen is banded with whitish, the bands rather indefinite 

 and not constricted in the centre. Toward the apex they are 

 rather diffuse and tend to cover the entire segments.
