Further characters taken from living $ . 



The male has a Y-shaped patch of creamy white upright scales 

 in the middle of the head, the broad end towards the eyes, a bare 

 median sulcus and the creamy scales in front long and thin, 

 almost in the form of long narrow-curved scales/ other upright 

 scales black; a single row of thin chaetae bordering the eyes, 

 the two outer long and far apart, then four shorter equal brown 

 ones, then two golden ones, arising from one base, then two long 

 pale hairs on each side. Eyes brilliant apple-green, copper and 

 purple at junction with head. 



The two apical segments of the palpi are uniformly swollen 

 and have dull purple and coppery reflections ; the apical segment

Anopheles barberi. Coquillett (1903). 



Canad. Entomo., p. 310 (1903). Coquillett; Eept. Ent. Dep. N. Jersey 

 Agri. Exp. St., p. 671 (1906), Smith. 



This species is near walkeri, but only about half as large, 

 according to Coquillett. It is called in America the Tree hole 

 Anopheles. 



There is little in the short description by which one can 

 separate it from A. bifurcatus, Linn., of which A. walkeri mihi 

 is a synonym. Size is of no value as I have bred bifurcatus 

 3 ■ 5 mm. long. Coquillett says, the petiole of first sub-marginal 

 cell is about one-third as long as cell, in all bifurcatus I have seen 

 it has been relatively much longer, and although this is a variable 

 character in bifurcatus the difference is so marked that it may 

 be taken to be of specific value.
