62 EXPERIMENT STATION RECORD. [Vol.41 



Technical descriptions are given of tlie several stages of these species, to- 

 gether with notes on their life history and habits in Nova Scotia and a report 

 of control work. 



Cutworms, R. W. Jack (Rhodesia Agr. Jour., 15 {1918), Nos. 3, pp. 225-237, 

 pis. 3, fig. 1; 4, pp. 344-348). — Four species of cutworms are recorded from 

 Rhodesia, namely, Euxoa segetis, E. longidentifera, E. spinifera, and the black 

 cutworm, of which E. segetis and the black cutworm are of real importance. 

 In a search for an effective remedy for E. segetis, the species occurring most 

 commonly in Ithodesia, 124 experiments were carried out at Salisbury. 



" While the results obtained with arsenite of soda against E. segetis are 

 unsatisfactory, the use of Paris green on green foliage was almost uniformly 

 successful against all species tested. [The black cutworm] and E. longiden- 

 tifera yield more readily to arsenite of soda than E. segetis. An even more 

 striking disparity of tastes is shown in connection with the use of bran in 

 making the bait, this carrier failing in every instance against E. segetis while 

 the other two species apparently eat it readily." 



A map showing the known distribution in Eng'land and Wales of the 

 anopheline mosquitoes, with explanatory text and notes, W. D. Lang (Lon- 

 don: Brit. Mils. (Nat. Hist.), 1918, pp. 63, pi. 1; rev. in Nature [London], 101 

 (191S), No. 2546, p. 463). — This map shows the known distribution in England 

 and Wales of three species of anopheline mosquitoes, namely, Anopheles ma- 

 culipcnnis, A. hifurcatus, and A. plumbeus, the first two of which are known 

 to be carriers of malaria. In the accompanying text the localities are arranged 

 alphabetically under each of the three species, primarily according to the 

 counties and secondarily according to the place names. A brief r§sum6 of 

 what is known of the life history of each species is also included. 



Notes on the Nearctic Nusa (Diptera, Asilidae), W, L. McAtee (Ohio Jour. 

 Sci., 19 (1919), No. 4, pp. 244-24S, figs. 5). 



Leiomyza in North America, J. M. Aldrich (Ent. Neivs, 30 (1919), No. 5, 

 pp. 137-141, fig. 1). 



Note on leskiine synonymy, C. H. T. Townsend (Proe. Ent. Soc. Wash., 21 

 (1919), No. 1, p. 20). 



Coleoptera illustrata, H. Notman (Brooklyn, N. Y.: Author [1915-1917], 

 vol. 1, pts. 1-4, pp. [14], Pfs. 200). — This volume contains 200 illustrations of 

 species of Carabidfe. 



Chrysobothris tranquebarica Gmel. versus impressa Fabr. (Coleoptera; 

 Buprestidae), W. S. Fishek (Proc. Ent. Soc. Wash., 20 (1918), No. 8, pp. 173- 

 177). — C. tranqiieharica is of considerable economic importan(;e, due to its 

 attacks upon the so-called Australian pine (Casuarina eqnisctifolia), which has 

 been planted quite extensively for ornamental and shade purposes in some parts 

 of Florida. 



The convergent ladybird beetle (Hippodamia convergens) and the barley 

 corn aphis (Aphis maidis), W. M. Davidson (Mo. But. Cal. Com. Hort., 8 

 (1919), No. 1, pp. 23-26, figs. 2). — This is a report of progress of a project 

 relating to the natural control of A. maidis by the convergent ladybird beetle, 

 started in the Imperial Valley of California in the spring of 1918. 



Mobilizing a ladybug army to fight the aphis, H. E. Thomas (Sci. Amer., 

 120 (1919), No. 20, pp. 507, 522, 524, fi<js. 3).— Attention is called to the fact 

 that 100.000,000 ladybird beetles will be distributed in the State of Washington 

 in the .spring of 1919, more than 25,000,000 having been stored ready for release. 

 The work is being carried on by the county agricultural agents in cooperation 

 with the Forest Service of the U. S. Department of Agriculture, the forest 

 ranger of which service has exceptional opportunities to find the caches of the
