from information collected by means of a list of questions drawn up by 

 the Bureau of Agricultural Intelligence and Plant Diseases and 

 circularised throughout the world. He points out the necessity for 

 concerted action against these insects, illustrating the futility of 

 suppressing them in one district when the source of their origin is 

 untouched. He reviews the different methods of control in vogue and 

 compares their degrees of efficiency. 



The report itself deals with the history and geographical distribution 

 of locusts. A list is given of the harmful species observed in the 

 different countries, comprising some 142 species, with the locality in 

 which each occurs. This information is repeated in tabular form later 

 in the report, when the food-plants are also given, as well as those plants 

 avoided by locusts. A chapter is devoted to the biology and habits of 

 locusts, and another to the organisation in force in each country for 

 controlling them. The methods of control are classified under : — 

 Natural enemies, mechanical, physical and chemical methods. Finally 

 the question of an international understanding on the question of the 

 control of locusts is discussed, and the following countries are given as 

 approving of the principle of sucli an agreement : — Portugal, Spain, 

 Italy, Austria, Hungary, Rumania, Greece, China, India, Morocco, 

 Tunis, Kamerun, Canada, the United States, Mexico and Trinidad. 



The report closes with a bibliography of several hundred references.

In the Konkan district of the Bombay Presidency ground-nuts 

 {Arachis hypognea) are attacked, both during and after the harvest, by 

 the Lygaeid bug, Aphanus i>ordidiis, which also infests Sesanium and 

 Carthamas tinctorius. The attacks may be prevented by putting the 

 mits into thick sacks innnediately they are gathered.

This article contains a description of Parectopa ciiharoda, Meyr., with 

 an account of its life-history and of the mines which it makes in the 

 leaves of the Australian broad- and narrow-leaved wattles {Acacia 

 pycnantha and A. saligna). Its indigenous food-plants are imknown.

The slides of Coccidae deposited by the late Mr. W. M. Maskell in the 

 Canterbury Museum are discussed. The author considers that 

 EriococcKS midtisjnntis, Msk., and E. pallidns, Msk., are identical, the 

 former name having priority. Dactylopia.^i poae, Msk., was des- 

 cribed from a damaged specimen of what appears to be a species of 

 Riper sia and is possibly identical with R. globatiis, Britt., which Avould
