Deraeocokis (Heteroptera, Miridae) 173 



The writer has found nyni})hs and adults on Fimts syk'csfris but 

 the species will doubtless be found on Finns rcsinosa also, a supposi- 

 tion based on the fact that three other species of Miridae, Phvfocnris 

 pinicoia Knight, Pilophonis sp. and Psallus sp. were found to be 

 breeding on both these pines. Since Piiiits syk'cstris is supposed to 

 have been introduced from Europe in recent times, the species of 

 Miridae mentioned must have bred originally only on Pinns rcsinosa 

 for it seems quite certain these insects are not known from Europe at 

 the present time.
