neighbourhood of King's Lynn, and was handed to him. On 

 examining its stomach he found two fresh and undigested 

 larvae of good size, which proved to be tho^e of the present 

 species. Doubtless the commoner green woodpecker knows 

 how to find such a succulent morsel, and this may help to 

 account for the comparative scarcity of the insect in the 

 country districts. 



It seems to be found occasionally in all the southern counties, 

 though recorded as rare in Devon and Somerset and even in 

 Sussex. Also found in Norfolk and Suffolk, Staffordshire, 

 Leicestershire and Herefordshire ; more commonly in Cam- 

 bridsfeshire: uncommon in Gloucestershire, scarce in Yorkshire 

 and recorded but once in Cheshire. I have no record in 

 Wales or Scotland, but in L-eland a single specimen which 

 seems to have been correctly determined, was seen some 

 years ago by Mr. D. C. Campbell in a local collection made 

 in the northern provinces. The owner is now dead, and the 

 specimen cannot be traced, but the insect is one which might 

 readily be transplanted with trees from a nursery, and it is 

 difficult to understand why it should not be far more widely 

 distributed, with us, than seems to be the case. 



It is found throughout Central and Southern Europe, in 

 Northern Africa, and the Western parts of Asia Minor. 

 Specimens which appear to be identical have been brought 

 even from Australia,
