HEMIPTERA HETEROPTERA 



Bugs 



Of this section of the Hemiptera 340 out of the 454 British 

 species have been recorded from Surrey, eleven (indicated in the list 

 by a prefixed *) not having thus far been recorded from elsewhere in 

 Britain. Gonocerus venafor has only been found on the box trees at 

 Box Hill, but on the continent it has occurred on various trees, and there 

 seems to be no reason why it should not occur elsewhere in England, 

 unless originally introduced. That this is possible is rather suggested 

 by its European distribution, which is given by Puton as ' Europe 

 centrale et meridionale,' as well as by the suspicion that its food plant 

 may also have established itself as an escape from cultivation. The only 

 other suspicious native of the eleven is Amblytylus delicatus, of which 

 about twelve examples were taken by myself at Woking on Gnaphalium 

 germankum ; the locality is now destroyed, but diligent search on the 

 same species of plant growing close by has failed to produce more, and 

 it is now twelve years since they were found. The road by the side of 

 which the Gnaphalium grew was then new and ' in the rough,' and just 

 in that condition which seems to encourage the growth of introduced 

 though apparently wild plants, such as Hieracium aurantiacum, etc., and 

 this makes me feel a little uncertain as to its being truly indigenous. I 

 hope however it may yet be rediscovered, as it is a particularly beautiful 

 little insect, and its food plant is common enough in the neighbourhood.
