1062 EXPERIMENT STATION RECORD. 



A land planariaii {BijxdlwH liewense) is reported as having frequently 

 been found in greenhouses and other situations, where it was suspected 

 of being injurious. This group of flatworras, however, is not known 

 to be injurious to plant life. This species is known to have lived in 

 the Kew greenhouses for a period of about 8 years. 



Dicranura mnula has attracted attention as being injurious to pop- 

 lars and willows. Where the attacks of this insect become serious, 

 the author recommends handpicking of the larva?. 



Notes are given on the habits and life history of Lamju'onia rahiella. 

 Perhaps the most effective method of checking the attack of this insect 

 consists in breaking off and destroying the infested Inids of rasplx-rries. 



A species of slug {Testacella Jmliotidea) is described and notes are 

 given on its habits. This species was observed eating earthworms, 

 and is, therefore, considered to be a beneficial species in greenhouses. 



The mottled willow weevil ( Oryptm^hynchm lapathi) has long been 

 known to be injurious to willows and alders in England. Where signs 

 of infestation Ijy this species are present, the infested branches should 

 be destroj^ed. When the beetles occur in large numbers on the foliage 

 of these trees, they ma}' be captured by the jarring method. 



Brief notes are given on Tmetoeera ocellana, Cryptococcus f(((/l , the 

 winter application of caustic alkali solution for bark beetles of fruit 

 trees Coplwriomyhi ruflxirh/s^ and /larpalus ruficornis. 



The Angoumois grain moth, J. B. Smith {New Jersey Stas. BuL 

 lJi.7^ pp. 8., figs. 2). — This insect is reported as having been unusually 

 injurious in 1900, causing a loss of about 25 per cent of the entire 

 crop of wheat in the State. The author describes the insect and gives 

 brief notes on its habits and life history. For preventing its ravages, 

 it is suggested that grain be thrashed as soon after harvesting as pos- 

 sible and placed in tight bins or sacks. The grain should be tested 

 occasionally in order to note any heating. If the grain heats decidedly, 

 a serious infestation of the insect may be suspected, and car])()n bisul- 

 phid should be used at once at the rate of 1 lb. per 250 cu. ft. of space, 

 or 1 dram per cu. ft. It is also recommended that all ])arns and store- 

 houses should be cleaned, so as to leave no exposed or scattered grain. 

 Such grain ma}^ be fed to hogs and chickens. 



Report on examination of vrheat stubble from cli£Ferent sec- 

 tions of the State; the joint-worm in -wheat, ^V. 1). Hoi'kins ( West 

 Virginia Sta. Bui. 69, pp. 333-350, pi. 1). — The author examined 

 wheat stubble from 24 counties of the State for the presence of the 

 Hessian fly. He found that nearl}' all of the flaxseed stage were dead, 

 and more than one-half of them had been killed by parasites. He 

 interpreted these conditions as indicating that the wheat prospects 

 were very encouraging. Tables are given with the names of corre- 

 spondents, post-offlce address, dates of sowing, etc., together with the 

 results of the examination of wln^at stu])ble, for the purpose of show-
