REPORT ON MOSQUITOES. 175 



single tooth near the base; one specimen examined showed two 

 teeth on this small claw, side by side. The posterior claws 

 (fig. 50, 4) and all those of the female are stout, equal and with a 

 single median tooth to each. 



The abdomen is dark brown above and beneath, with whitish 

 scales irregularly scattered over the whole surface, more so ven- 

 trally. The dorsal surface appears to have a light-colored central 

 stripe, as the light happens to strike it. 



Habits of the Adult. 



This is the largest of our New Jersey mosquitoes and its bite 

 is in proportion to its size; but it does not seem to be so poisonous 

 as that of the smaller species. Clothing is little protection when 

 it really wishes to bite, for it gets through coat, vest and two 

 shirts to the skin without any trouble whatever. It seems, how- 

 ever, that it prefers horses to humans and it certainly never 

 attacks in swarms. It is not averse to getting indoors if it can 

 do so without much effort, and it is not infrequently sent in with 

 house captures. In flight it is somewhat slow and heavy, and 

 I doubt whether it ever gets very far away from the place where 

 it bred. 



The method of hibernation is not definitely known, but is 

 probably in the egg stage. Adults have never been taken very 

 early in the season, and it is not until June that the species 

 attracts attention in any stage. It continues, however, through 

 September and to the early days of October, so far as our 

 records go. 



It is distributed throughout the State, but is usually rare. 

 Only on occasions when a brood has just emerged is it possible 

 to find them in numbers. A few are taken in New Brunswick- 

 every summer. Mr. Grossbeck found the species commonly at 

 Spring Lake, near Trenton, July 2d ; a single specimen- occurred 

 at Hackensack, August 8th; one at Jamesburg, August i6th; 

 two examples at Livingston Park, August 27th, and that con- 

 cludes the slip record of captures. A few examples only are 

 taken during the summer at Lahaway in spite of the close search 

 made by Mr. Brakeley, and, on the whole, unless one goes into 

 the haunts of this species in the woodlands, it can scarcely be 

 called reallv troublesome.
