132 THE MOSQUITOES OF NEW JERSEY 



evenly rounded in front ; in color yellowish with large dark brown 

 blotches which give predominating shade. From anterior part of vertex 

 arise four single hairs, each from separate pit ; pits so arranged as to 

 form square, narrower in front ; small tuft of four or five hairs at the 

 base of each antenna. Antennae short, evenly tapered apically, yellow, 

 becoming very dark brown toward apex ; surface set with rather large 

 spines with very small ones intermingled. Tuft, consisting of eight or 

 ten hairs, situated on shaft slightly below middle. Apex has one long 

 spine, two shorter ones, and small joint, all articulated. Eyes are nor- 

 mal, usually with broad, pale yellow ring. Rotary mouth brushes pecti- 

 nated on apical third of the more central hairs. Mentum triangular 

 with slightly curved sides of fifteen small teeth each. Mandible has small 

 spines on dorsal surface of base, and maxilliary palpus has moderate 

 apical tuft, rather large basal joint and patches of hair over surface. 



Thorax large and stout, with two transverse depressions and smaller 

 transverse wrinkles on dorsum. Sides angulated, each angle giving rise 

 to long hair tufts ; two very small hair tufts on anterior margin. 



Abdominal segments chunky, anterior two broad, with four or five 

 hairs in each lateral tuft ; segments four to seven subquadrate, with 

 two hairs to lateral tuft, except seventh, which has small tufts only. 

 Lateral combs of eighth segment have each fourteen to twenty-two 

 scales. Single scale broad, with rather long acute barb and several 

 smaller ones on sides, becoming shorter toward base. Anal siphon short, 

 about two and one-half times as long as its width at base, dark brown, 

 almost black, with the valves slightly dilated, so as to flare at tip. 

 Spines composing double row curved, with two or three teeth at base, 

 terminal spine sometimes without teeth. From thirteen to eighteen 

 spines in each row. Ninth segment almost square, completely ringed by 

 chitinized saddle same color as siphon. Ventral brush moderate, with 

 two or three small tufts below barred area. Double dorsal tufts normal, 

 each with very long hair as usual. Anal gills short, about same length 

 as ninth segment. 



HABITS OF THE EARLY STAGES 



Very little is actually known concerning the early stages, full grown 

 larvae and pupae only being at hand. It is probable that the species 

 winters in the egg stage, and that it is not an early species. The larvae 

 were first taken during the last days of June from pools in the wood- 

 lands back of South Orange, in company with A. vexans and P. ferox, 

 and additional material obtained July 2 showed the same combination 

 of species. Collections made August 11 and 12 in the Hatfield swamp
