to murli parasitic iurestation. After the last iikhiK, tli'' eaterpillars 

 spreai! out ti\-er the fruit trees. 



They then seem tu hirsahe tlieir nest, ami they devour the 

 leafage wholesale. 



Frem the end of duue to the 

 beginuiug of duly they sjiiii 

 cocoons amongst the leaves of 

 the fruit trees, as ;i rule se\eral 

 together firming a large mass 

 united hy a dusky web. In their 

 cocoons tlie\' change to deep 

 brown ]iupa'. Kullar (2) says 

 as many as tweh'c cocoons ma\' 

 be gathered into one ball. 



Some years agii I cijunted as 

 many as forty on a damson tree 

 in one mass (4). From these 

 pup;r the nidtlis come out in 

 tlie latter part of duly and in 

 August, and sonn Ijcgiu to lay 

 their long egn-masses.

 comnam tm the (Jimtiuent, do 

 not occur, as far as we know, 

 in Britain. They are consideri'd

The only abundant parasite 

 that 1 haA'e come acr(jss in 



Britain is a Tachinid fly, 'llirl iiiimriilia ri'rfliii iiasn ^ Fl. This fly 

 appeared in great nanrbers in I'.MIl, and I feel sure had a large share 

 in stamping out this moth ((i).
