bling those of M. rossi possess very fine lateral branches. 

 Palmate Hairs. — Note that in these the body of the leaflet 

 is at least twice as long as the spine or filament and that in- 

 stead of being finely tapered off it frequently looks rather 

 rough and broken. In old larvae the upper portion of the 

 leaflet is usually much darker in colour just at the point 

 where the filament joins it. 



M. harbirostris . 

 Examine the larvae and note that the internal pair of 

 frontal hairs are very long and often appear to cross one 

 another at the tip. Sometimes they have one or more very 

 fine branches. The external frontal hairs are possessed of 

 numerous branches like the" branches of a tree or bush. It 

 is sometimes difficult to see them on account of the projec- 

 tion of the feeding brushes. If we examine the antennae 

 of a larvae of M. harbirostris we shall also find a somewhat 

 similar branched hair projecting from its inner surface 

 about half-way up. 



Examine the palmate hairs or fans which are present on each 

 side of the abdominal segments. In larvae of this 

 species found in Bombay there is also a pair present on 

 the thorax. The individual leaflets of the fans are rather 

 large and coarsely tapered to a point and are not extended 

 into any marked filament or spine as in the case of most 

 other larvae. 



_ZV. jamesi. 

 Examine the larvae and note that the frontal hairs have a 

 laro'e number of fine lateral branches all the way up. 

 These are to be seen on both internal and external 

 frontal hairs. The palmate hairs or fans are very large 

 and distinct, with rather wide broken-looking and slightly 

 pigmented tops and a mediumly long spine or filament. 



M. culicifacies. 



Examine the larvae and note that the internal frontal hairs 

 are rather short and possess one or two fine lateral branches
