The hairs exhibit great variation in different 

 species, but are quite constant in the one species. 

 A minute description of these hairs is of great 

 importance in describing the specific characters of 

 the larva. 

 Clypeal Hairs of Larvae : — 



(i) The four anterior hairs may be quite 

 simple and unbranched. M. rossii, N. stephensi, 

 M. cuUcifactes,M. listoni, M.turkhudi, A.bifurcatus. 



(ii) All four anterior hairs may shew small 

 lateral branches. .P. jeyporensis. 



In A. macM^'^enms all four hairs are branched, 

 the outer pair form distinct tufts. 



(iii) The outer pair may be markedly 

 branched, e.g., Ce. pulcherrima and M. pseudoptctus. 



(iv) The outer pair may be developed into 

 a close tuft (cockade), e.g., M. barbtrostvts, A.^puncti- 

 pennis.

I. M. rossii, N. stephensi, M. culicifacies, M. listoni 



2. N. maculipal-pis. 3. P jeyporensis. 4. Ce. pulcherrima 



5. M. sinensis, M, barbirostris 



The two hairs situated behind these may, 

 instead of being very short and inconspicuous, be 

 long and prominent, e.g., M. turkhiidi.
