man who took them informs me that on turning

 observed at least fifty specimens. 



The Onthophilus sulcatus and striatus are 

 both found in the vicinity of Nottingham ; 

 the former very rarely, but always near dead 

 animals: the latter has been extremely abun- 

 dant this spring, (1830) in the usual haunts of 

 the Histeridae and Aphodiidae. 



Cetonia aurata Rose May-Chaffer, or Brass 

 Beetle. This beautiful insect is not confined 

 to the south, some hundreds of specimens have 

 been captured in this county, and I have some 

 which were taken at Matlock. 



Scolytus Destructor. No one from a casual 

 survey of this little creature would deem it 

 capable of such extensive devastation: its 

 ravages are confined to the Elm (Ulmus com- 

 pestris), the mid-bark of which it perforates in 

 a circular direction, in some instances com- 

 pleting the circumference of the tree and de- 

 positing eggs during its progress. The larvae 

 which are produced from these eggs perforate 

 the bark at right angles with the perforation of 

 the mother insect, both upwards and down- 

 wards. The female is generally found dead at
