The pests and blights of the tea plant, G. AVatt and H. H. Mann {Calcutta: 

 Supt. Govt. Printing, 1903, 2. cd., pp. XY+429, 2)ls. 24, figs. 44). —This handbook on 

 the insect and fungus pests of the tea plant has been largely rewritten in the j)reseiit 

 edition. The purpose of the volume is to i^resent a general account of cultural 

 methods adapted to preventing the attacks of insects and fungus enemies, and to 

 furnish biological and economic accounts of the chief pests of tea. As stated by the 

 authors, the purpose of the cultural suggestions made by them is to furnish data 

 regarding methods which "should necessarily accompany more specific efforts to 

 battle with the pests and blights." About one-third of the A^olume is occupied with 

 cultural details, while the remaining two-thirds is devoted to a discussion of insects 

 and fungus enemies. The insects are classified into natural orders and discussed in 

 a systematic manner. The majority of the species are well illustrated. Among the 

 numerous species Avhich are discussed mention may be made of a few of the more 

 important ones, including Lachnosterna impressa, Diapromorpha melanopus, Amatissa 

 consorta, Bracliytrypes achatinus, Helop>eltis theivora, CMorita fiavescevs, Cvylonia the;r- 

 cola, Termes taprobanes, and Tetranychus bioculatus. A number of fungus diseases of 

 tea is considered (pp. 392-416). The more important of these are due to the fol- 

 lowing si^ecies: Stilbum nanum, Cephaleuros mycoidea, and Nectria ditissima. 



White fly (Aleurodes citri), H. A. Gossard {Florida Sta. Bui. 67, pp. 595-666, 

 pis. 6, figs. 3). — A general account is given on the family Aleurodida?, with special 

 reference to the white fly. The original home of this insect is not definitely known, 

 but it is believed to be Florida. It is also found in Louisiana, Georgia, North Caro- 

 lina, Texas, and the District of Columbia. The insect is described in detail in its 

 various stages. It is considered to be the Avorst orange pest of Florida, and is kno\\-n 

 to be established in 14 counties of that State. There are 3 broods, Avhich occur from 

 March to May, June to August, and September to November, respectively. The 

 eggs are deposited uj)on the leaves. The insect is distributed greatly by nursery 

 shipments, wind currents, and various vehicles. The chief natural enemies of the 

 insect are brown fungus, Aschersonia aleurodis, and other species of parasitic fungi as 

 well as ladybirds. In experiments to discoA'er the effect of cold storage the wliite 

 fly Avas killed by subjection to temperatures of 10 to 20° F. for jieriods A'arying from 

 1 to 48 hours. Notes are given on the food plants of this insect. Among the insei'ti- 

 cides discussed by the author mention should be naade of resin sprays, kerosene
