 Wash., 7 {1905), No. 2-3, pp. 65-152, figs. 12).— -In this number the following papers 

 are included: 



Descriptions of New American Spiders; New Trichoptera from Japan; Descriptions

 Larva; The Spread of Sphseridium scarabseoides, by H. S. Barber; Kirby's Catalogues 

 of Orthoptera; The Species of the Genus Chimarocephala and Descriptions of Two 

 New Species of Californian Orthoptera, by A. N. Caudell; Notes on Eulecanium fol-

 Larva of Castnin licus; A Few Notes on the Strecker Collection, by H. G. Dyar;

 New Species of Desmocerus With a Synoptic Table of the Genus, by J. L. Webb; 

 and A New Enemy of Timothy, by F. M. Webster. 



The enemy of timothy reported from various States from New York to North Dakota 

 appears to be a species of Isosoma. The larva works in the joints of timothy in much 

 the same manner as does I. grande. A number of parasites were raised from the 

 insect. The pest causes a shortening of the stem and shrinkage of the seed crop, 

 and is, therefore, considered a serious enemy of timothy. 



Thirty-sixth annual report of the Entomological Society of Ontario (.1////. 

 Rpt. Knl. Snr. Ontario, 36 (1905), pp. 143, figs. 74)- — This report contains an account 

 of the proceedings of the forty-second annual meeting of the society, held at Guelph, 

 Ontario, October 18 and 19, 1905. 



During the different meetings of the society various papers on economic entomol- 

 ogy w T ere read, some of which are mentioned in the following notes: A number of 

 reports were presented on the status of insect pests in different districts. In this 

 report it appeared that the woolly aphis, zebra caterpillar, cottony maple scale, wire 

 worms, and codling moth were unusually abundant. The tussock moths were dis- 

 cussed by T. W. Fyles and H. H. Lyman. These moths do an unusual amount of 

 damage to ornamental and shade trees, causing considerable interest to be developed 

 in methods of extermination. Notes were presented on the entomological conditions 

 in North Carolina, by F. Sherman, jr. 



W. Lochhead read a paper on experiments against the San Jose scale in 1905. It 

 is stated that in Ontario the lime-sulphur wash has been successfully used, made 

 according to the formula 20-15-40. Various other combinations of these ingredients 

 have also been used in the preparation of washes with or without boiling. Little or 

 no difference was observed in the effectiveness of the boiled and unboiled washes. 

 In order to prevent the great multiplication of the San Jose scale in the fall, it is 

 necessary that the insecticide should adhere to the trees for long periods. 



J. B. Smith reviewed briefly the work on mosquitoes in New Jersey, and reports 

 were given of the councils of the various branches of the society. 



A number of other papers were read, some of which are mentioned in the follow- 

 ing list: Insects as nature studies, by S. B. McCready; forest insects, by T. W. Fyles; 

 insects injurious to Ontario crops in 1905, by J. Fletcher; an entomological record 

 for 1905, by J. Fletcher; injurious insects of the flower garden, by A. Gibson; forest 

 entomology, by E. J. Zavitz; phlox mite, spruce saw-fly, and bumblebees that fer- 

 tilize the red clover, by T. D. Jarvis; injurious insects of 1905, in Ontario, by W. 

 Lochhead. 



Tenth annual report of the State entomologist of Minnesota, 1905, F. L.
