With reference to the occurrence of Diaspis pentagona (mulberry 

 scale) in Brazil, attention is drawn to the fact that its parasite, 

 Prospdltella berlesei, is now obtainable, and that supplies can be had 

 from the phy to pathological service.

The presence of Aspidiotus perniciosus, Comst. (San Jose scale) 

 was discovered in Brazil in January 1921. The infested plum and 

 apple trees had been obtained from a nursery in which plants 

 imported in 1919 from California, Buenos Aires and Montevideo 

 were found to be infested. The infestation had begun to spread to 

 native fruit-trees. 



A brief account of this scale, its distribution, food-plants and control 

 is given, and quarantine measures are advised, including the supervision 

 of imports from infested countries and of all plants from the infested 

 area and the immediate inspection of all orchards that have received 

 plants from it.

The object of this paper is to facilitate the identification of Canadian 

 species of Syrphus, which is at present rendered difficult owing to the 

 scattered nature of the descriptions. A key to the species is given. 

 These include three new ones.

Aphelinus ma/i, Hald., the Chalcid parasite of Eriosoma lamgerum, 

 Hausm., has been imported from America and successfully established 

 in various districts in France. Its general distribution over the country 

 is considered to be only a matter of time. Under natural conditions 

 hibernation occurs in the larval or pupal stage within the host larva. 

 During 1921 the first adults emerged towards the end of March.

Halticus citri (garden flea-hopper) is generally distributed throughout 

 the eastern half of the United States and sometimes causes a loss of 

 v50 to 60 per cent, of the lucerne crop. The tj'pe of injury found on 

 lucerne, red and white clover, and cowpeas is discussed ; damage is 

 also done to almost all garden vegetables, in greenhouses all the yea.T 

 round, and to out-of-door flowering plants in early spring and late
