from nearly all parts of the civilized world, and is a well-known, pest in herbaria and 

 drng stores. It may be destroyed in infested seed by fumigation. Complaints were 

 made that orange trees were being attacked by Bostrychopsis jeswita. It is believed 

 by the author, however, that this beetle did not attack the trees until after they 

 were dead, or nearly dead. Related species of this genus are known to attack forest 

 trees in a living condition in Germany and elsewhere. Descriptive and economic 

 notes are given on Mecyna polygonalis, reported as occurring on broom corn ; Teara 

 contraria, which is reported as especially injurious to eucalyptus; San Jose scale; and 

 Halterophora capitaia. The last-named species was observed crawling over oranges 

 and depositing their eggs in the skin of the fruit. 



Report of the entomologist, W. W. Froggatt {Agr. Gaz. New South Wales, 12 

 {1901), No. 8, pp. 915-920). — Mention is made of the various lines of work under- 

 taken by the entomologist, and of the addition in collections and equipment made to 

 the department during the previous year. Special attention is given to the study of 

 the San Jose scale, Plusia vertidllata, Agrotis suffusa, and various species of fleas. 



Insects injurious to staple crops, E. D. Sanderson [New York: John Wiley & 

 So7is, 1902, pp. 295, figs. 162). — This volume contains a compilation of information 

 concerning the chief insect pests of staple agricultural crops, together with observa- 

 tions from the personal experience of the author. Chapters of the book are devoted 

 to insects injurious to the following crops: Grains and grasses, wheat, Indian corn, 

 clover, cotton, tobacco, potato, sugar beet, and hop plant. One chapter is occupied 

 with a discussion of insects injurious to stored grain. A general discussion of insec- 

 ticides is given at the end of the volume. In connection with the treatment of each 

 crop for insect enemies, special attention is given to a consideration of various cultural 

 methods which are adapted to preventing injury from the insects by which the crop 

 is naturally attacked. 



The Colorado potato beetle, F. V. Theobold [Jour. Bd. Agr. [London'], 8 {1901), 

 No. 2, pp. 147-154, pi- 1) ■ — This insect recently secured a foothold in England and 

 was found breeding in considerable numbers. All stages of the insect were found in 

 one large field of potatoes. The infested locality at Tilbury was burned over with 

 kerosene, the ground was then saturated with kerosene and dressed with gas lime, 

 which later was plowed under. All surrounding herbage was cut and burned, and 

 an examination of the country for a distance of 3^ miles in all directions indicated 

 that the beetle had been exterminated. The life history and habits of the insect 

 are gone over anew from original observations. A list of food plants is given. At 

 Tilbury the beetle is said to have matured on tomatoes. Notes are given on the 

 natural enemies and means of combating the potato beetle. The author considers 

 that the climatic conditions in Great Britain are favorable to the establishment and 

 development of the Colorado potato beetle, and urges the necessity of keeping sharp 

 outlook to prevent its becoming thoroughly established in the country. 



The apple sawfly (./ow. Bd. Agr. [London], 8 {1901) , No. 2, pp. 183-187, fig. 1).— 

 Injuries from Hoplocampa tesludinea have been reported for 2 years on apples. The 

 attack of the insect resembles somewhat that of the codling moth. The female 

 appears in the spring at the time when the apple blossoms are opening, and deposits 

 its eggs, usually one in each blossom, below the calyx. Under certain conditions 

 there may be 2 broods of the insect each year. It is recommended that infested 

 fruit should be removed from the trees and destroyed. Some help may be expected 

 from thorough cultivation of the soil underlying the trees, but spraying does not 

 promise much good in combating this insect. 



Notes on Coccidae {Contrih. Biol. Hopkins Seaside Lab. Leland Stanford Jr. Univ., 

 1901, No. 25, pp. 387-420, 1-14, pls. 6, fig. 1).— Notes on C'erococcus, Rose W. Patterson 

 (pp. 387-398). — The author gives detailed description and biological notes on C. 

 ehrhorni, found on live-oaks; C. quercns, reported as abundant on oaks in Arizona and 

 southern California; and C. corticis. A black fungus is reported to occur in connection 

 with the last-named species.
