THE CLASSIFICATION OF CULICID^ 



(9) Mansonia scales (6). 



(10) Small broad asymmetrical scales (c). 



Various other varieties are found on the wings, such as : 



(1) Narrow linear lateral scales. 



(2) Narrow lanceolate scales. 



(3) Broad lanceolate scales. 



(4) Elongated, broad, truncated scales (= Pseudotseniorhynchus-like scales). 



(5) Pyriform scales. 



(6) Asymmetrical broad or Taeniorhynchus scales. 



(7) Flat spade-like scales. 1 



The wings have a series of scales along the middle line of the veins, and also 

 lateral scales to all or nearly all the veins. The wing is also fringed by a series of 

 scales (fig. 396), which, however, are of little systematic importance ; the so-called 

 " border scales " (b.s.) vary, however, to some extent, and are useful characters in 

 separating some of the Taeniorhynchus.
