Anopheles rossi. 



Colonel Giles, in the 2nd Edition of his Handbook, describes 

 the abdomen as being completely clothed with yellowish and deep 

 brown scales. This is incorrect, for the abdomen is devoid of scales. 

 The male genitalia are also wrongly described as being characteristic. 

 These points are corrected in his "Revision of the Anophelinae." 



Mr. Theobald now admits that his indica is nothing more 

 than a specimen of culicifacies.
