 without touching the wood, jufl: as they do in their ufual food the 

 poplar, though the linie tree bark is not half fo thick. 



This fpecies is diftinguifhed from the following by its mode 

 of life, and difference of colour. It is alfo much bigger. The 

 head is wholly yellow, the peftinated part of the anten?ii£ orange, 

 and the markings on the thorax much larger than in the crabronl- 

 formis, and nearly fquare,, Neither is the whore infedl of fo dark,

 The larua feeds on the wood of the fallow, Salix Capraa, in the 

 heart of which^it fpins itfelf up in November, but does not change 

 to a pupa till May following. The fly comes out in the middle of 



July. 



This larva enters the wood near the furface of the ground, 

 fomctimes from th; root, and feeds upwards (generally in the pith) 

 for the fpace of fix or eight inches ; after which it turns its head 

 downwards, and fpins itfelf up with the web, there waiting the 

 proper time to change.
