274 AGRICULTURAL EXPERniEXT STATION. 



The pleura are chestnut brown, almost covered with patches of 

 silver}' white scales. The femora are black, yellowish beneath 

 and with a whitish spot at the knee; the tibiae are black, paler 

 beneath and the tarsi are wholly black. T,he claws oi the male 

 anterior and mid tarsal joints (fig. 83, 3 and 4) are unequal in 

 size, the larger evenly cur\'ed, wnth a single median tooth, and 

 the smaller almost straight with a median tooth slightly nearer 

 the base; the claws of the posterior tarsal joints are equal and 

 simple. The claws of the female are equal on all feet; those of 

 the anterior and mid tarsal joints single toothed, the posterior 

 simple like the male. 



The abdomen is black, with brown hairs on the apical margin 

 of the anterior segments, extending backward over those follow- 

 ing. Beneath it is creamy white, with pure white basal marks 

 extending up the sides and coming well upon the dorsal surface 

 in the posterior segments ; the apical segment yellowish. In the 

 male the white marks sometimes cross the abdomen as narrow^ 

 basal bands. 



Habits of the Adidt. 



This is rather a handsome species and one that is rarely found 

 outside of woodland or its immediate vicinity. It occurs through- 

 out the State, records of captures of adult or early stages coming 

 from Lahaway, in Ocean County ; Xew Brunswick, in Middlesex 

 County ; the Great Piece meadows, Chester and Lake Hopatcong, 

 in [Morris County, and the environs of Newark, in Essex 

 County. There is no reasonable doubt but that the species 

 occurs throughout the State. 



It is one of the species that winters in the tgg stage, either 

 under water or in a place where water is likely to come in early 

 spring. The adult lays its eggs as near to the surface of the 

 water as possible, at the very edge of the vessel or cavity selected 

 for a breeding place, and these eggs hatch, after a suitable period 

 for development, when they become covered with water. 



The earliest date that I have for adults is June ist, when the 

 species was the common form found on the dams around the 

 cranberry meadows at Lahaw^ay, and from that date until 

 October adults were taken in some part of the State. Practi- 

 cally all of the collectors took triseriatiis in some stage, hence, 

 though it is by no means a common mosquito, it is at least easily 

 captured by the careful collector. 



There is no record that the species has bten at any time taken 

 indoors under anv circumstances ; but there is a clean record of 

 its occurrence on porches of houses closely surrounded by trees.
