(i) The four anterior hairs may be quite simple 
and unbranched, e.g., M. rossi, N. stephensi, M. culici- 
facies, M. listoni, M. turkhudi, bifurcatus. 
(ii) All four anterior hairs may shew small 
lateral branches, e.g., P. jeyporensis. 
In A. maculipennis 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. pseudopictus. 
(iv.) The outer pair may be developed into a 
close tuft (cockade), e.g., M. barbirostris, A. puncti- 
pennis, Ce. squamosa.

1. 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 . Phe Pborax. — (a) Observe on the dorsum of 
the thorax a short but extremely stout and strong hair, 
unlike the others, projecting outwards and forwards. 
(b) A flap-like body may, with careful focussing, 
be seen lying at the base of the most anterior hairs on 
either side.
