April or May, bef?iiiuiiig about lu days or 2 weeks after the spring brood of 

 adults bas quite disappeared. Summer spraying for white tly can be prac- 

 ticed whenever the trees need relief, but the periods when the adult white flies 

 are swarming in greatest number should be avoided. 



Catalogue of the neartic Hemiptera-Heteroptera, N. Banks {Philadelphia, 

 1910, pp. 103+VlII). — The 30 families listed represent 1,268 species. The 

 family Capsidre is represented by 348 species, Lygteidte by IGO, Pentatomidte by 

 149, and Coreida? by 108. 



Gipsy and brown-tail moth suppression, F. W. Rane {A7i)i. Rpt. State 

 Forester Mass., 6 (1909), pp. 67-109, pis. 5, fig. i).— During 1909, the maximum 

 number of men engaged in the work at any one time was 2,750, with 150 large 

 power outfits in operation and 200 hand outfits. The known spread of the 

 gipsy moth is said to have been very slight, although new infestations were 

 found in Hopedale, liancaster, Mendon, and Northborough. The total area in 

 Massachusetts known to be infested at the end of the year comprised some 

 3.950 square miles. During the season 7.776 acres were sprayed, using 300 tons 

 of arsenate of lead, and 698,597 burlaps and 26,313 tangle-foot bands were 

 placed on trees, A nozzle that will carry the stream much higher than any 

 used previously was invented for use in woodland. 



Investigations of the diseases of the two moths were continued. The work 

 with insect parasites is said to show very satisfactory progress. Information 

 furnished by W. F. Fiske is given on five of the more important imported para- 

 sites, namely, AnasrtaUis bifasciatus, Schedius kcvance, Glyptapanteles fiilvipes, 

 Blepharipa seutellata, and Monodoiitomcriis a'riis. The importation and breed- 

 ing of the predaceous beetle (Calosoma syeophanta) was continued with good 

 results, 33 colonies being planted during the year. A brief report on the intro- 

 duction of parasites by Dr. L. O. Howard of this Department, under whose 

 direction the work is carried on, is incorporated in the author's report. 



The codling moth, C. P. Van Der Merwe (Dept. Agr. Orange River Colony 

 Bui. 20, pp. Iff, figs. 1). — ^This is a summarized account of the codling moth 

 with remedial measures. The pest is said to be continually spreading into nnin- 

 fested territory in the Orange River Colony. 



Papers on cereal and forage insects. The New Mexico range caterpillar, 

 C. N. AiNSLiE {U. S. Dept. Ayr., Bur. 1-Jnt. Bui. .SJ. pt. 5. pp. 59-96. pis. 2. figs. 

 22). — The details of a study made of the range cateri)illar {Hemileuca oliviw) 

 in northeastern New Mexico during the adult period of the insect in 1908 and 

 the entire active life period of 1909 are here reported. 



The injury by the caterpillar is due, not only to its eating grama, buffalo and 

 other grasses down to the roots but to the trail of silk which it leaves every- 

 where, especially during the molting season. The area at present infested is 

 known to extend from just north of Las Vegas, N. Mex., on the south, to Las 

 Animas, Colo., on the north, and from Cimarron and Koehler, N. Mex., on the 

 west, to points well within the Texas " Panhandle " on the east. This area, 

 about 30,00<J square miles, is infested very unevenly as yet. but with the insect 

 more or less prevalent everywhere. The species was first described by I'rof. 

 T. D. a. Cockerell, some 12 years ago, from a male collected at Santa Fe, 

 N. Mex., and is now known to occur also in Texas, Oklahoma, and Colorado. 

 Technical descriptions of the several stages, including the 5 larval, prepared by 

 Dr. H. G. Dyar are presented with illustrations. 



The life history and habits of the moth have been carefully worked out and 

 are described in detail. Oviposition c(mimences about October 1, dissections of 

 females showing that as many as 162 eggs may l)e deposited. It is the habit of 

 the moth to deposit the eggs alxtut a weetl or grass stem within an inch or two 

 from the ground, about 2 hours being required under favorable circumstances
