CENEkA OF ANOPHELINA 



4. No scales on the abdomen (very rarely there may be a few 



scattered and inconspicuous scales on the genital lobes). Anopheles. 

 Abdominal scales present, usually as a small outstanding 

 tuft on the ventral surface of the penultimate segment, 

 rarely as a uniform covering to the terminal segment . Myzorhynchus. 

 2. The predominant scales of the head are of the ' upright 



forked' kind (cuneiform). ., - Nyssorhynchus. 



The predominant scales of the head are not ' upright forked ' . Chagasia. 



Alcock arranges the species of Myzomyla in two intergrading series 

 as follows: 



a. The covering of the scutum consists mainly of hairs . . Myzomyia. 



b. The covering of the scutum consists mainly of falculate scales. Pyretophorus. 



The species of Nyssorhynchus he arranges in three distinct series as 

 follows : 



a. Abdominal scales present on few of the distal segments . . Nyssorhynchus 



b. Abdominal scales scattered on all the segments . . . Neocellia. 

 e. Abdominal scales fairly abundant on all the segments, and 



also in outstanding tufts which may be either lateral or 



ventral Cellia. 



In the subgenus Anopheles, Meig., Alcock includes Anopheles, Ste- 

 thomyia and Cyclolepidopteron grabhaml of Theobald's monograph, and 

 Neostethopheles and Patagiamya of James. 



In the subgenus Myzorhynchus, Blanchard, are included Myzorhynchus 

 and Lophoscelomyia of Theobald's monograph. 



In the subgenus Arribalzagia, Theobald, are included Arribalzagia, 

 Kertezia, and part of Cyclolepidopteron of Theobald's monograph. 



In the subgenus Myzomyia, Blanchard, are included Myzomyia, Felti- 

 nella, Neomyzomyia and Pyretophorus of Theobald's monograph and 

 Nyssomyzomyia of James. 



In the subgenus Nyssorhynchus, Blanchard, are included Nyssorhyn- 

 chus, Neocellia and Cellia of Theobald's monograph ; Calvertina of 

 Ludlow, and Christophersia of James. 



In the subgenus Chagasia, Cruz, Alcock includes Chagasia, Cruz, and 

 Myzorhynchella, Theobald. 



In the descriptions which follow all the species will be referred to 

 under the generic name Anopheles (sensu lato), the more restricted 

 genera of Theobald being given in brackets so that the worker can refer 

 to Theobald's classification of the genera of the subfamily Anophelinae, 

 which is given below. 



Theobald's Table of the Genera of the Anophelinae. 



A. First submarginal cell large. 



! Antennal segments without dense lateral scale tufts.
