(i) The four anterior hairs may be quite simple 

 and unbranched, e.g., M. rossi, N. stepbensi, M. culici- 

 facies, M. listoni, M. turkbudi, A. bifurcates. 



(ii) All four anterior hairs may shew small 

 lateral branches, e.g., P. jeyporensis. 



In A. maculi-pennis all four hairs are branched, the 

 outer pair form distinct tufts. 



(iii) The outer pair may be markedly branched, 

 e.g., Ce. -pulckerrima and M. pseudopictus. 



(iv.) The outer pair may be developed into a 

 close tuft (cockade), e.g., M. barbirostris, A. puncti- 

 pennis, Ce. squamosa.

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



2. N. maculipalpis 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. turkhudi. 



6. The Thorax. (a) Observe on the dorsum of 

 the thorax a short but extremely stout and strong hair, 

 unlike the others, projecting outwards and forwards. 



(Z>) A flap-like -body may, with careful focussing, 

 be seen lying at the base of the most anterior hairs on 

 either side.
