the base, while in the mid tarsus each has but a single tooth. The 

 posterior claws (fig. 63, 5) are equal, simple and rather sharply 

 curved toward their apices. The claws of the female are equal 

 on all feet, one toothed in the anterior and mid tarsal joints (fig. 

 6T), 2) and simple in the hind pair as in the male. 



The abdomen is black, each segment with a narrow basal band 

 of white crossing the segments and with small lateral white spots 

 beginning on the second segment, becoming larger posteriorly, till 

 in the apical two or three segments they encroach well upon the 

 dorsal surface. Beneath it is yellowish brown, apically banded 

 with black. 



Habits of the Adult. 



In a general way, the habits of this species are like those of 

 soUicitanSj but it is not nearly so abundant. It is strictly a marsh 

 mosquito, and has never been bred anywhere else, but it also mi- 

 grates, though not so generally and not so far. It reaches New 

 Brunswick from the Raritan meadows in small numbers, but it 

 has never been sent in by Mr. Brakeley from Lahaway, so that 

 it is distinctl}^ inferior in its spread to both sollicitans and canta- 

 tor. Nor is it equally abundant throughout its range. From 

 the sections north of the Barnegat Bay, collections early in the 

 season have shown few or no specimens : later they become more 

 abundant; but from two to ten per cent, of the bred specimens 

 was the best secured at any time from the collections made by 

 Messrs. Brehme and Grossbeck. At Atlantic City I found the 

 species active and biting during the day quite as abundantly as 

 sollicitans. At Anglesea a series of porch captures in August 

 made during the late afternoon, showed both species equally pres- 

 ent. In the examination of Mr. Viereck's material some lots 

 were nearly 50 per cent, tceniorhynchiis, and in one lot of between 

 four hundred and five hundred only five per cent, were sollicitans, 

 the remaining 95 per cent, being of this species. These, however, 

 are abnormal percentages, and on the marsh itself the captured 

 adults show no such equality with the larger species. I have 

 never observed tceniorhynchus crawl up the legs of the marsh 

 tramper as its ally does, but it may do so where it is most abund- 

 ant. 



Mr. Viereck failed for a long time to find gravid examples of 

 this species, but late in the season he collected a lot of specimens 

 attracted to the electric lights and found them mostly gravid ex- 

 amples of tccniorhyncliits, sollicitans, salinarins and crucians. He 

 duplicated that collection later and thereafter found no difficulty
