dorsal tuft and ventral brush shorter than normal, completely encircled 

 by chitinized saddle ; gills very short ; often no longer than broad. 



HABITS OF THE EARLY STAGES 



The larvae of taeniorhynchus occur with those of sollicitans and 

 cantator, and the habits are similar to those species. None of our col- 

 lections show larvae of this species only ; as a rule they are in the small 

 minority. In a mass of partly grown larvae there is little apparent 

 difference between the three species, but when full grown the maculate 

 heads of cantator and taeniorhynchus are characteristic, while the very 

 short anal siphon distinguishes taeniorhynchus from cantator. As the 

 species is more southern in its range, sollicitans is its companion more 

 frequently than cantator.

 The Daylight Anopheles 



DISTRIBUTION AND CHARACTERIZATION 



[Seacoast of southeastern United States from New York to Texas. 

 Trapped 26,717 females in New Jersey.] 



Smallest of New Jersey Anopheles species, some specimens as large 

 as An. punctipennis. Brown, not quite as dark as punctipennis, thorax 

 striped with grayish scales, wing veins clothed with whitish and black 

 scales, black ones especially collected along the wing margin. 



DESCRIPTION OF THE ADULT 



Species averages 4-5 mm. (.16-20 inch) long, beak about half as 

 long as body. Head dark brown with scattered yellowish scales at angle 

 of eyes ; tuft of 3'ellowish hair from between eyes projects forward over 

 head. Narrow line of similarly colored scales forms border to posterior 

 margin of eyes. Proboscis evenly dark brown. Palpi in female same in 

 shape as other species of Anopheles, but dark brown, almost black, with 

 apical joint, base of penultimate and of antepenultimate joints white. 

 Male palpi dark brown with long yellowish hairs toward apex. Antennae 

 dark brown in female, paler in male. 



Dorsum of thorax brown, mottled at sides with grayish scales, nar- 

 row stripes of grayish scales down central part ; pleura and legs same 

 as in punctipennis, but latter not nearly as dark. Wings hyaline, with 

 black, whitish, and gray scales as follows : costa, black ; subcosta, black ;
