REPORT ON MOSQUITOES. 169 



This arrangement is best seen when held longitudinally on a level 

 with the eye. The pleura and legs are the same as in piinctipcn- 

 nis. The wings are hyaline; all the veins clothed with brown 

 scales, and some darker ones collecting verv densely in four parts 

 of the wing as follows: one, on radius i, at the cross vein where 

 radius 2 begins; one each at the base of cell radius 2 and cell 

 media 2, and another at the three cross veins, on radius 2, radius 

 4 and 5, and media i and 2. 



The abdomen is the same as in punctipcnnis, but paler brown. 



Habits of the Adult. 



This species occurs throughout the State, but is decidedly 

 more abundant northwardly. It also occurs in Europe, and is, 

 perhaps, the most common of all the species which have been 

 definitely convicted of transmitting malaria. 



Description of the Larva. 



The figures of A. punctipcnnis larva will serve for this species 

 also. No differences between the larvse appear in the alcoholic 

 material, though it is probable that in living specimens the vesti- 

 ture may have a slightly different arrangement. 



Habits of the Early Stages. 



In a general way, these agree with what has been already said 

 concerning the other species. The breeding places are similar, 

 but this form also occurs in brackish water on the salt marshes, 

 hence has a somewhat wider range and adds the positive danger 

 of disease to the disadvantages of an undrained marsh. 



ANOPHKIvKS CRUCIANS, WIKD. 



The Day-light Anopheles. 



This is the smallest of the New Jersey species, though some 

 specimens are as large as A. pimctipennis. It is brown, not 

 quite as dark as pimctipennis, with the thorax striped with 

 grayish scales, the wing veins clothed with whitish and black 

 scales, the black ones especially collected along the wing margin.
