INSECTS 



right discovered, at Lynn, that the 

 greater spotted woodpecker extracts the 

 larvae of this species from their burrows 

 in the twigs of trees, and thereby- 

 doubtless prevents its becoming com- 

 mon

 buted, and very destructive to willow, 

 poplar, ash, and oak trees, its larva 

 burrowing under the bark and through 

 the solid wood, and causing decay

Hypogymna dispar, Linn. At the beginning 

 of the present century, or the end of the 

 last, very plentiful at Horning, where 

 Curtis found it flourishing in such abun- 

 dance that ' eggs, caterpillars, chrysa- 

 lides and moths ' could all be collected 

 by him upon the same day. It was 

 also found at Cawston, and there con- 

 tinued until the year 1861, since which 

 period it has not, I think, been observed 

 at large in the county, and scarcely in 

 any other part of the British Isles
