lanceolate structure. About the third day, the 

 hairs are seen with seven to eight uniformly lanceo- 

 late leaves. Very soon after this, they take on 

 the characters sfeen in the hairs of the mature 

 larva. 



In the mature larva the leaflets shew much 

 variation in the different species. In most species, 

 the leaflets terminate rather suddenly in a number 

 of jagged points ^ or notches, whilst the central 

 portion continues as a more or less fine filament.

The character of the notching and the relative 

 length of the filament to the leaflet are of specific 

 importance. The following types of leaflets are 

 known : — 



I. The leaflets are unbrokenly lanceolate in 

 shape, with saw-like notches along the edge of the 

 outer half. There is no distinct terminal filament.
