REPORT OX MOSQUITOES. 171 



The abdomen, as in allied species, is dark brown with yellowish 

 brown hairs evenly scattered over the surface. 



Habits of the Adult. 



Attention has been alreadv directed to the fact that this species 

 is not closelv confined to the hours of darkness, but flies and bites 

 freely long before dusk and long after sunrise. It bites quite as 

 hard as either of the others and is as eager to get indoors. At 

 Cape May, which is the only place where I have found it at all 

 abundant, it is the most annoying indoor form and far more 

 troublesome than C. pipiens. Isolated examples of the species 

 have been taken at Lahaway, Delair and Port Reading, but the 

 only real home of the species in New Jersey is Cape May County, 

 and its chief breeding place is in the Cape Marsh, which is else- 

 where referred to at some length. 



Description of the Larva. 



The larva of this species with details is illustrated at figure 49. 

 It does not differ in general appearance from those of A. puiic- 

 tipennis and A. macuUpennies, but is a little smaller, ranging 

 from 5.5 to 6 mm., = .22 to .24 of an inch in length when full 

 grown. In color it is dirty grayish brown, with the usual varia- 

 tion of the other larvje. The white dorsal stripe may be present 

 in living larvae, but there is no indications of it in alcoholic speci- 

 mens. The maculation of the vertex is variable, much larger 

 than in the other species and with much less defined edges. The 

 second joint of the antenna (fig. 3) is shorter and does not 

 taper as much apically as in allied species, but is very blunt, with 

 two long spines serrated on one edge and six long hairs, which 

 have a common center ; the color is dark brown, pale yellow at 

 the base, with the surface set with rather long spines ; the four 

 branched hair larger and situated one-third the length of the 

 antenna from the base. The mandible (fig. 5) and maxillary 

 palpus (fig. 4) are of the normal Anopheles form, the former 

 with four, instead of three, curv^ed dorsal spines, three of them 

 feathered on one side; the latter with the two apical processes 

 spatulate in form. The dorsal plates on each of the abdominal 

 segments are large and the circular spots beneath them very 

 obvious. The respiratory apparatus is very similar to that of 

 maailipennis and punctipennis. The lateral combs consist each 

 of a large plate, the posterior edge with seven or eight long stiff 

 spines and with ten or twelve shorter spines between them. The
