and 5 oz. of arsenate of soda dissolved in 50 gal. of water and a solution double 

 this strength) were made resulted in the preservation of 55 per cent of the 

 twigs which would otherwise have fallen, where the weaker strength was used, 

 and of 85 per cent where the stronger spray was applied. 



Technical descriptions of the stages of the beetle accompany the account. 



Twenty-fifth report of the state entomologist on the noxious and bene- 

 ficial insects of the State of Illinois, S. A. Forbes (Rpt. Stale Ent. III., 25 

 {1909}, pp. XXIII+123, pis. 3, figs. 35). — This report is composed of 3 papers 

 which have previously been noted as Bulletins 130, 131 and 134 of the Illinois 

 Experiment Station (E. S. R.. 21, pp. 57, 58, 453).

Fourth annual report of the state entomologist of the State of Maine, E. F. 

 HiTCHiNGS {Ann. Rpt. State Ent. Maine, // {1908), pp. 10, pis. 9). — Among the 

 insects that were the source of injury during 1908 was the tarnished plant bug, 

 which injured dahlia, chrysanthemum, and aster buds, as well as the buds and 

 young fruit of the apple. The saddled prominent {Heterocampa guttivitta) 

 again appeared in considerable numbers, thousands of acres of hard-wood 

 growth in the belt extending from the New Hampshire line at Fryeburg to 

 beyond Skowhegan, being stripped bare. Details of the gipsy-moth work are 

 reported by E. E. Philbrook. Fifteen towns in the State are reported to have 

 been infested in 1908. A catalogue of the land, fresh-water, and marine mol- 

 lusca of Maine, by N. W. Lermond, is appended. 



[Report on insects and insecticides], J. L. Phillips {Rpt. State Ent. and 

 Plant Path. Ya., 1 {1908-9), pp. 1-56, 99-113, pis. 6, figs. 13).— The work from 

 October 1, 1907, to September 30, 1909, is discussed in this report. 



The details of nursery inspection are first presented, together with the treat- 

 ment of nursery stock by fumigation. During 1909, nests of the brown-tail 

 moth were found to have been introduced on imported nursery stock at 4 dif- 

 ferent points, about 40 nests being discovered and destroyed. 



Summarized accounts are given of the more important insect pests and the 

 remedial measures applicable. The gloomy scale is stated to be one of the most 

 important injurious insects affecting shade trees in Virginia. The periodical 

 cicada was observed at Fishers Hill in 1909. 



Directions for the use of lime-sulphur, kerosene emulsion, and soluble oils 

 are included in the report. 



Injurious insects of the Montreal region in 1908, J. M. Swaine {Ann. Rpt. 

 Quebec Soc. Protec. Plants [e<c.], 1 {1908-9), pp. 11-23, figs. 5).— A brief report 

 on the occurrence of insect pests. 



Insect pests in 1909, R. S. Macdougall {Trans. Highland and Agr. Soc. 

 Scot., 5. ser., 22 {1910), pp. 75-90, figs. 3). — The insects noted are the large 

 larch saw-fly {Nematus erichsoni), Chermes viridis, C. aMctis, C. strobilobius, 

 magpie moth, currant saw-fly (V. rihesii), Loehmcea suturalis, and frit fly 

 {Oscinis frit). 



Report on economic zoology for the year ending April 1, 1908, F. V. Theo- 

 bald {Jour. Southeast. Agr. Col. Wye, 1908, So. 11. pp. 65-182, pis. 2.1,, figs. .')).— 

 The arrangement of this report is similar to that of 1907 (E. S. R., 20, p. 651), 

 the important animal pests of the year being considered under the several crops, 

 etc., to which they were a source of injury. 



Among the more important pests mentioned are the raspberry weevil {An- 

 thonomus rubi), which invaded cherry plantations in Worcestershire; Entomo- 

 brya nivalis, which injured hops in Kent ; Argyresthia Icevigatella, which attacked 

 larches; Dascillus cervinus, which injured grass in Ireland; and Nacerdes 

 melanura, which was a source of damage to woodwork at Wisbech. Winter
