scabs (Sarcoptida?, Demodecida\ and Linguatulina) are here brought 

 together. 



Remedies and preventive treatment (pp. 277-285). — The value of fish oil, 

 tar, train oil, axle grease, pennyroyal, and dipping solutions is consid- 

 ered, along with other well-known insecticides. In the case of infested 

 henhouses, the author thinks the best plan is to burn the structure if it 

 is not of too great value. But where this course is impractical, and 

 where the walls are tight enough to retain the fumes, fumigation with 

 sulphur and drenching the roosts with kerosene or hot water and then 

 whitewashing them are recommended, or covering the ends of the poles 

 with tar may be practiced with success. The addition of carbolic acid 

 at the rate of 4 oz. to a gallon of whitewash to increase the efficacy 

 of the latter is recommended. Various methods of fumigation of ani- 

 mals placed in stalls or covered with blankets are brought out, and a 

 plan for constructing a large dipping vat is described and figured. 



The San Jose or pernicious scale, W. B. Alwood ( Virginia sia. 

 Bui. 62, pp. 31-44, Jigs. 5). — A popular bulletin on Aspidiotus perni- 

 ciosus, briefly recounting the introduction of the insect into the United 

 States and its occurrence in Virginia and other parts of the East, with 

 illustrated, descriptive, life history, and remedial notes. Besides the 

 infested district at Charlottesville, where the species was first observed 

 in 1893, the scale has been found in but one other locality in the State — 

 a large orchard near City Point. Through lack of systematic treat- 

 ment the scale has not been satisfactorily subjugated, and further 

 infestation is anticipated. Directions are given for detecting the 

 presence of the insect, and its great fecundity and numerous food 

 plants are briefly mentioned. 



The use of a winter wash of lye registering 5° Bauine and of soap- 

 suds or kerosene emulsion as a summer wash is advised. The text of 

 an act of the legislature giving the station power of inspection and 

 treatment of the scale within the State is quoted. 



Food plants of the San Jose scale in Ohio, exclusive of fruit 

 trees, F. M. Webster {Canadian Ent., 29 (1897), No. 7, p. 173). — 

 Besides the several varieties of roses, currants, raspberries, and goose- 

 berries, Aspidiotus perniciosus has been found upon the following 

 plants: Grape (Vitis labrusca), linden (Tilia americana), European lin- 

 den (T. europwa), sumac (Rhus glabra), Japan quince (Pyrus japonica), 

 cotoneaster ( Cotoneaster frigidum), flowering peach (Prunus sp.), flow- 

 ering cherry (P. sp.), American elm (Uhnus americana), black walnut 

 (Juglans nigra), imported willow (Salix rerminalis), cut-leafed birch 

 (Betula sp.), lombardy poplar (Populus dilatata), Carolina poplar (P. 

 monUifera), golden leaf poplar (P. ran gerti), catalpa (C. spcciosa), 

 chestnut (Castanea sativa), osage orange (Madura aurantiaea), and 

 snowball (Viburnum opulus). The cotoneaster, which was sent for 

 inspection, was found literally covered with the scale. 



Notes on the codling moth, F. W. Card (Card, and Forest, 10 

 (1897), 493, pp. 302, 303). — Failure in applications of the accepted doc- 

 trines in regard to this moth induced a thorough investigation of its
