3i6 AGRICULTURAL EXPERIMENT STATION. 



glers occur in the pails quite as early as those of pipiens, and Mr. 

 Brakeley has found them in the water in an ornamental vase at 

 Lahaway in October, 



CULEX SALINARIUS, COQ. 



The Unhanded Salt Marsh Mosquito. 



This species is so likeC pipiens, the ordinary house or rain 

 barrel mosquito, that the description of the latter will apply to 

 the present form. In all structural details save the tip of the 

 female palpi, the drawings for the one will answer for the other 

 as well. Salinariiis, however, which was called nigritulus in my 

 earlier papers, is somewhat slighter in build, giving the legs an 

 appearance of unusual length. In the female the white bands of 

 the abdomen are narrower and better defined, while, as a whole, 

 the mosquito seems blacker in color. In a long series of adults 

 from various localities the lanky and generally darker appearance 

 would form the best characters for their separation. If the spec- 

 imens are a little rubbed or in alcohol, there is no distinguishing 

 them. 



Habits of the Adult. 



This is the only one of the salt marsh mosquitoes that does not 

 migrate for any considerable distance, and the only one of them 

 that hibernates in the adult stage. It seems much more abundant 

 on the Newark and Elizabeth marshes than it does further south, 

 and at Cape May it was not found by Mr. Viereck until well 

 along in the season. It is a night flier and, on the marshes 

 where sollicitans and cantator rise up to greet the visitor, nigri- 

 tulus will not be seen at all. But in the early evening it flies 

 readily and is as greedy for blood as any other of the species. 

 It sings like pipiens and has the same tendency to get into 

 houses, though perhaps not so well marked. Hibernating speci- 

 mens have been found by Mr. Brehme in buildings along the 

 edge of the marshes, and it is cjuite possible that the insects come 

 up into the edge of the cities even though they fly no further 

 inland. Thev remain in hibernation until April and continue 

 breeding until October. 



Mr. Viereck observed their marriage flight at Cape May on 

 two occasions, just at nightfall. An egg boat is formed as in 

 case of pipiens and rcstuans, but the aggregation of eggs is 

 smaller in number.
