The Coleoptera Committee was represented by Messrs. 

 iC. G. Bayford and H. H. Corbett. Beetles were scarce, a 

 remark which applies with equal truth to the other orders of the 

 Insecta. Perhaps the most noticeable was a male specimen 

 of Strangalia armata Herbst., in which the black markings were 

 increased to such a degree as to reduce the yellow ground 

 colour to very small dimensions. The other species noted were 

 all common ones : — 



Harpalus ruficornis F. Hyphydrus ovatus L.- 



Pterostichus diligens Sturm. Hydroporus pictiis F. 



Haliplus fulviis F. Malthodes tnarginatus Latr. 



Neuroptera. — Panorpa communis L. was one of the com- 

 monest of insects near Shirley Pool : a female specimen was 

 brought to the meeting in order to draw attention to the 

 scorpion-like terminal abdominal segments. T. W. W.

In Knowledge for July, Mr. A. M. Broadley contributes a well-illus- 

 trated article, entitled ' A Knowledge of the Origin and Early History of 

 the Royal Horticultural Society as derived from contemporary medals,
