LIST OF COLEOPTEROUS INSECTS. 175 



not be equally efficacious if applied to tlie turnips ; only it must 

 be used when the " blacks" are confined to the few plants on 

 which they have been bred, as its cost would, I fear, preclude its 

 being spread over the whole field. Another destructive insect, 

 Scolytus destructor^ affecting elm trees, previously recorded in our 

 " Transactions," from the banks of the Tyne and Derwent, would 

 appear to be spreading over the district; for I have this season 

 detected it breeding, in some plenty, in the Gosforth woods. 



Our Coleojjtei^ous fauna has, during the year, been enriched by 

 the occurrence of the following species : — 



1. Patrohus lappojiicus, Chaudoir 2 This interesting addition to 



the British fauna has occurred within our limits, having 

 been taken near Wallington by Dr. Power, in 1855; and 

 by myself, on Prestwick Carr, several years ago. I have 

 also several specimens from the Cumberland moors. 

 Although widely spread, this very distinct insect re- 

 mained unnoticed in many of our collections, until 1858, 

 when the capture of a few specimens, by Mr. H. Squire, 

 in Shetland, led to its identification. The species with 

 which it was mixed (excavatus) is one of our commonest 

 beetles, which, occurring everywhere, had not sufficient 

 interest to claim more than a very superficial examina- 

 tion at the hands of collectors, and hence the confusion. 

 This shows us how carefully every object of natural his- 

 tory, however common, ought to be studied before being 

 finally placed in our cabinets. 



2. Harpalus Utigiosiis, Dej. A single specimen of this rare 



species was taken on the banks of the Derwent, in August, 

 by Mr. H. Adams. 



3. Ocalea hadia^ Erich. From the banks of the Devil's Water. 



September. 



4. Aleochara hrevipennis, Grav. I have some local specimens of 



Aleochara, which appear to be referrible to this species. 



5. Aleochara bilitieata, Gyll. Several specimens from the sands 



at South Shields, in July. 



6. Philonthus dehiliSy Grav. Taken at Gosforth and South 



Shields. Rare.
