ANOPHELES. 



The species of this genus most common in the lower Sus- 

 quehanna River breeding district are A. maculipennis Meig. 

 and A. punctipennis Say, where I have taken the larvae from 

 the standing waters in the bed of the tide-water canal. 



DAY HABITS. 



Adults of both these species were taken from the windows in 

 houses (on damp days) in March, 1901. In April they be- 

 come active outdoors, more particularly in a garden where the 

 shrubbery seemed to be full of them, In an old shop, close to 

 this garden, they were also numerous, and at these two places 

 the attacks from these insects were fierce and persistent in day 

 time during the month of April. On the iyth, a warm day, 

 were very numerous and seemed determined for blood. They 

 appeared in the garden mostly in the afternoon and allowed 

 themselves to be pushed from place to place on the back of 

 one's hand. A member of the family while at repose in the 

 middle of the day was bitten on her arm by an A. punctipennis 

 in five places, which was caused by the victim in her sleep push- 

 ing the mosquito around until five rosy spots with pale centres 

 were left on her arm. This demonstrates the persistence in 

 getting the first sop after a season of rest. The more persist- 

 ent specimens seem to have been the gravid females. And this 

 peculiarity attending the day habit of these species I have only 

 observed with their first appearance in the spring. 



A. maculipennis is the most common in breeding district of 

 the Susquehanna River, where it was found in such abundance 

 that the people living in certain localities were obliged to kill 

 numbers every evening before retiring. In small sleeping 

 rooms in some dwellings gravid females, in some instances of 

 unusual size, even without charge of ova and blood, were 

 taken from rooms where the blood was often extracted from 

 small children. Mosquitoes and malaria in this, like other 

 localities, even these days of better knowledge, is still tolera- 

 ted. From summer cottages on the banks of the Susquehanna 

 I have known whole families to return home with malarial 

 fever, and numerous individual cases whose infection was re- 

 ceived from a visit along the river.
