5'5& JOURNAL OF THE EOYAL HOETICULTUEAL SOCIETY. 



Twenty-six insects (including Jca;*/, myriapods, and crustaceans) injurious 

 to Violets are described, the nature of the injuries they cause and 

 the best remedies are detailed, and in most cases figures are given of the 

 pests in their various stages of development. The writer strongly recom- 

 mends the use of hydrocyanic gas, and gives full directions for its manu- 

 facture &c. as a remedy against most of these pests, but mentions that 

 it is not of much use as a remedy against " red spider," which are easiest 

 destroyed by the application of flowers of sulphur, either dry or as a wash 

 combined with soapsuds. As, however, A'iolets are easily injured by 

 sulphur, a wash of only soap and water is recommended in their case : it 

 should be applied with a syringe, fitted with a spray nozzle, to the under- 

 sides of the leaves. Eleven of the insects which attack Roses are 

 described (tc, but, curiously, no mention is made of any Aphides. The 

 bulletin closes with descriptions &c. of a caterpillar attacking the Tobacco 

 plant, another which injures the Morning Glory, and a midge frequently 

 found in glasshouses, whose grubs are supposed by some persons to feed 

 on the roots of plants.— 6'. S. S.
