solution of sodium salicylate is slightly less efficient than formaldehyde, but 

 that it possesses certain marked advantages, especially for household use. The 

 best results with formaldehyde were obtained from a solution containing 1 

 per cent of the formaldehyde, or 2.5 per cent of the 40 per cent solution. 



Suggestions for the control of tjie more serious insect pests occurring at 

 Hood River, L. Childs (Oregon Sta. Bui. 141 (1917), pp. 33, 3Jf).— These notes 

 relate to the leaf-roller, brown aphis, woolly apple aphis, green apple aphis, 

 codling moth, pear leaf blister mite, and San Jos4 scale. 



[Report of the] division of zoology and entomology (Washington Sta. Bui. 

 136 (1917), pp. 35-42, figs. 8). — Brief reference is made to the occurrence of 

 and work with the coulee cricket (Peranabrus scabricollis) , noted below. 



Work with the strawberry root weevil (Otiorhynchus ovatus) has been 

 carried on under a special appropriation made by the commissioners of Benton 

 County, where it has appeared in the Kennewick region and rendered acres of 

 berry field.'' worthless. In the course of the work, which was based principally 

 on soil fumigation, numerous materials were tested. Carbon disulphid is the 

 only material that has given promise of practical value, and this only when 

 applied under a cover, such as oil cloth, canvas, etc. 



Brief reference is made to the continuation of work on progressive immunity 

 of insects, an account of which has been previously noted (E. S. R., 34, p. 551). 

 A discussion of the physiological effects of endoparasitlsm In aphids Is also 

 included. 



Annual report on the entomological laboratory for the year ended March 

 31, 1914, T. J. Andkkson (Dept. Agr. Brit. East Africa Ann. lipt. 1913-14, PP- 

 52-83). — Tills is the report of the work of the year with the more important 

 Insects, particularly with the coconut beetle {Oryctcs monoccros). 



List of Egyptian insects in the collection of the Ministry of Agriculture, 

 G. Storky (ilin. Agr. Egypt, Tech. and .Sri. Sen: Bui. 5 (1916), pp. V+50).—iJt 

 the 154 families represented in the list here pre.sented about 100 are said to 

 include species of economic Interest. 



The fauna of British India, including Ceylon and Burma, eillted by A. E. 

 Shipley and G. A. K. Marshall (London: Taylor d Francis, 1916, vol. 6, pp 

 VIII+2.'f8, figs. 177). — This volume of the work previously noteil (E. S. R., 2."i. 

 p. 557), Is an appendix to the Homoptera, by W. L. Distant, and de.scribes 348 

 species of which many are new. 



The coulee cricket [Peranabrus scabricollis], A. L. Melander and M. A. 

 YoTHEKs (Washington Sta. Bui. 137 (1917), pp. 56. figs. 37).— The first part of 

 this bulletin (pp. 5-35), by A. L. Melander, consists of a general discussion and 

 photographs; the second part (pp. 36-50), by M. A. Yothers, consists of miscel- 

 laneous notes on the biology of the coulee cricket (P. scabricollis), a brief 

 account relating to the control of which has been previously noted (E. S. R., 

 35, p. 756). 



This cricket has been a .source of injury In Washington State since 1899, when 

 outbreaks were first observed by C. V. Piper. It occurs sporadically In re.strlcte<l 

 localities In the Big Bend country of central Washington, where Immense 

 migratory hordes destroy whatever vegetation grows In their pathway. It 

 breeds In nonarable areas characterized by the presence of scabland sage brush 

 (Artemisia rigida), among the fallen leaves of which the newly hatche<l crickets 

 secure protection In early spring. During the first four of Its seven stages the 

 cricket feeds in the breeding grounds and at the fifth instar It begins moving 

 in bands and .spreads over miles of country. The eggs are deiwslted singly 

 during the migration whenever the insects come to a favorable location, usually 

 at the base of grass stems, each female averaging about 50 eggs. This cricket
