72 ENTOMOLOGY FOR MEDICAL OFFICERS 



Anopheles barberi, Coquillett. From Maryland. Super- 

 ficially has a close resemblance to A. bifurcatus, but has the 

 head covered with simple hairs, and has plumose lateral hairs 

 on the 6th abdominal segment. 



Anopheles perplexens, Ludlow. From Pennsylvania. The 

 scales of the wing are all dark except for a few minute 

 yellowish spots, namely two on the front edge, one in the 

 wing-fringe at the end of the 3rd longitudinal vein, and one 

 on each fork of the 4th vein. The extreme tip of the 

 palps are white, and the extreme tips of the femora and 

 tibise are yellowish. 



Anopheles quadriniaculatus, Say, is, according to Theobald, 

 a synonym of A. maculipennis. 



Anopheles occidentalis,V>ya.x z.n^ Knab. From the Eastern 

 States. Is perhaps only a variety of A. maculipennis. 



Anopheles alropos, Dya.r a.r\d Knah. From Florida. Like 

 A. maculipennis, but smaller and having the four black spots 

 of the wing only just suggested. 



Anopheles crucians, Wiedemann. Apparently a common 

 species. The wings are spotted, and their front edge has 

 one pale spot. The palps have two white bands and a white 

 tip, and the tip of the femora and tibise is yellow. 



Anopheles punctipennis, Say. There are two yellow spots 

 on the front edge of the wing one of them being at the tip. 

 The wing-fringe is not spotted. The palps have two very 

 obscure grey bands and a greyish tip. The tip of the femora 

 and tibiae is yellow. 



Anopheles franciscanus, M'Cracken. From Texas and 

 California. Seems to differ from A. punctipennis in having a 

 series of yellow spots on the wing-fringe. From the descrip- 

 tion it is not easy to distinguish this proposed species from 

 the South American A. pseudopunctipennis. 



5. Neotropical Species {Central and South America 

 and West Indies). 



Anopheles eiscni, Coquillett. Gautemala. Front edge of 

 the wing not spotted. 



Anopheles pseudopunctipennis, Theobald. Grenada. The 

 wing has two yellow spots on the front edge, and a series of
