Exhibilions. 



Mr. Stevens exhibited a specimen of Dynastes Actfeon from Peru, and another 

 which he believed might prove a distinct species, also from South America, but the 

 exact locality was unknown. 



Mr. Holdsworth exhibited a piece of the wood of a Scotch fir perforated by the 

 larva; of Sirex. duplex. Shuck. The insects had done considerable injury to a planta- 

 tion of those trees, and he inquired of the Members present whether any means could 

 be adopted for destroying them. It was observed that the structure of the ovipositor 

 in the female of this species proved beyond doubt that the eggs are deposited under 

 the bark, and as the larvae eat into the solid wood of the trees there appeared no way 

 of checking their ravages but by cutting down the infected trees, and destroying the 

 perfect insects.
