ENTOMOLOGY. 367 



ical notes are given on Plusia gamma (pp. o3-58). The species is I'eported as injurious 

 to mustard and potatoes. Arsenical poisons are recommended in destroying this 

 insect. The pear-leaf bhster mite (pp. 59-62) is descrilied and brief notes given on 

 its hfe history, hal)its, and means of prevention. Diphsis pyrivora (pp. 63-69) is 

 spreading and becoming more injurious. In combating this species the infested pears 

 which have fallen should be collected and destroyed. The trees may be shaken for 

 the purpose of removing other infested fruit which does not fall. It is also recom- 

 mended that cloths be spread under the trees and kept smeared with tar or other 

 substance, which will prevent the escape of larvje which fall or emerge from infested 

 fruit. 



Notes are given on the habits, life history, and remedies for Scolytus pruni (pp, 

 69-72), Penthina rariegana (pp. 73-78), Archerontia atropos (pp. 82-84), Lampronia, 

 rubiella (pp. 85-88), and (Estrus oris (pp. 89-94). 



A planarian worm [BijMlium keirense) is reported as having been found in a num- 

 ber of greenhouses. The species is somewhat beneficial from its habit of feeding 

 upon earthworms, and thus checking a too great prcA'alence of the latter in green- 

 houses. Short biological and economic notes are also given on Psijlla mali, currant 

 sawfly, }fame>!tra broitsicx; and Retimia buoliana. 



Report on injurious insects and plant diseases in 1900, W. 'M. Schoyex 

 [Beretning am Skadeinsekter og Plantesygdomme i 1900. Christiania, 1901, pp. 34, figs. 

 21) . — In this report the author gives economic and biological notes on a number 

 of injurious insects and fungus diseases affecting cereals, grasses, potatoes, cabbage, 

 turnips, peas, beans, fruit trees, small fruits, shade trees, evergreen trees, and orna- 

 mental plants. Among the injurious insects which are discussed mention may be 

 made of Charmis graminis, wireworms, cabbage-root maggot, Silpha opaca, destruc- 

 tive pea aphis, apple maggot, codling moth, Cheimatobia bnunata, PhyUobins argenta- 

 tus, Hyponomeuta varabilis, Eriocampa adumbrata, pear-leaf blister mite, currant 

 sawfiy, Cossus ligniperda, Lasiocampa pini, and earwigs. Notes are also given on the 

 cereal rusts, Gloeosporium lindemuthianum, apple scab, gooseberry rust, and .Ecidiuin 

 strobllhmm. 



Notes on insects, W. Lochhead {Ontario Agr. Col. and Expt. Farm Rpi. 1900, 

 pp. 13-15, figs. 2). — The buffalo carpet beetle is reported as having occurred in 

 unusual numbers during the season. Ih combating this insect it is recommended 

 that the beetles be prevented from entering houses by the use of window screens 

 during the month of May, when the beetles are flying most actively. Infested car- 

 pets may be treated with gasoline along the borders, and the same treatment should 

 be applied to the floors under; the borders of the carpet. 



The codling moth occurred in about the usual numbers. Legislation has been 

 adopted permitting municipalities to enforce the application of })ands to apple trees 

 from the first week in June. It is urged, however, that this method is successful 

 only when the bands are carefully examined at frequent intervals. 



Many complaints are reported concerning the ravages of the Hessian fly. It is 

 recommended that narrow strips of wheat be sown 4 or 5 weeks earlier than the 

 main crop in order to entice the insects to lay their eggs. This wheat may then be 

 plowed under so as to destroy the eggs. 



Report of the entomolog'ists, C. H. and H. T. Fernald {Massachusetts Sta. Rpt. 

 1900, pp. 84-88). — The San Jose scale is reported as having been received from 37 

 towns in the State, and it is lielieved that there are other unreported localities of 

 infestation. Brief notes are given on periodical cicada, birch Bucculatrix, Mar- 

 guerite fly, greenhouse Aleurodes, fall cankervvorm, and pea louse.
