at Manchester, England, of the malacoderm beetle T. lituratus. The larvae 

 were found among and below the roots of grass at a depth of about 2 in., but 

 were more abundant near the roots of trees, especially elder and rhododendron. 

 It appears that the larvae are primarily carnivorous, but whether they are 

 beneficial is doubtful. 



Notes on the twelve-spotted cucumber beetle, R. A. Sell (Jour. Econ. Ent., 

 9 {1916), No. 6, pp. 551-556) .—These notes relate to the biology of Diabrotica 

 duodecim-punctata, which is becoming more numerous in southern Texas. 



The rose flea-beetle (Haltica probata), G. F. Moznette {Jour. Ent. and Zool., 

 9 {1917), No. 1, pp. 13-19, figs. 7). — A brief account is given of the seasonal 

 life history and habits of H. probata, to which, in a review of the literature, 

 the author has failed to find more than a brief reference. This species has 

 been reported from Spokane, Wash., and Nelson, B. C, attacking the straw- 

 berry, and at various times has been reported as feeding on cultivated crops 

 in Oregon. It is distributed along the Pacific coast from British Columbia to 

 California, and there appears to be some possibility of its becoming destruc- 

 tive to cultivated roses. 



Observations on its life history and habits are given, together with tech- 

 nical descriptions of its several stages. 



Otiorhynchus sulcatus, an enemy of pot plants, N. A. Kemner {Trddgdrden 

 [Stockholm], No. 18 {1916), p. 145, figs. 2; abs. in Rev. Appl. Ent., Ser. A, 4 

 {1916), No. 8, pp. S54, 355). — The larvae of this weevil are often introduced into 

 pots with soil from infested greenhouses, and instances are known where as 

 many as 20 larvse have been found in one pot. The adults damage the leaves 

 of various plants, especially ferns, rhododendrons, orchids, etc. The injury 

 to the roots by the larvae, though much more serious, Is often overlooked. 



The leaf weevil (Polydrusus impressifrons) in New York, P. J. Parrott 

 and H. Glasgow {Ann. Rpt. Ent. Soc. Ontario, 46 {1915), pp. 60-65). — The leaf 

 weevil, preliminary studies of which are reported, is a new and, until the 

 inception of this study, an unrecorded enemy of shade and fruit trees in this 

 country, brief reference to which has been previously noted (E. S. R., 29 p. 252). 

 Its range in New York State has not been definitely established, but it Is 

 known to have become established in Ontario, Monroe, and Wayne counties, 

 and to occur in scattering numbers as far west as Albion, in Orleans County. 

 The damage which it causes is due to nibbling the unfolding buds and then 

 attacking the foliage, preferring the margins of the leaves. Where sufiiciently 

 abundant to warrant their use, it is thought that arsenicals will control it. 



Notes on the control of the white pine weevil, S. A. Graham (Jour. Econ. 

 Ent., 9 {1916), No. 6, pp. 549-551).— During the season of 1916 the author ap- 

 plied different materials at various strengths to young pine trees in an effort 

 to control Pissodes strobi. Of the materials used, none but creosote and car- 

 bolineum proved effective. The results seem to warrant a further trial of 

 these two materials and also Tanglefoot, which was applied to 40 trees, on a 

 larger stale. 



An Indian ant introduced into the United States, W. M. Wheeler {Jour. 

 Econ. Ent., 9 {1916), No. 6, pp. 566-569, fig. i).— This paper records the collec- 

 tion of Triglyphothrix striatidens at Audubon Park, La., in August, 1913, and 

 gives a description and drawing of it and a review of its literature. 



Two new genera of North American Entedoninae (chalcid flies), A. A. 

 GiRAULT {Canad. Ent., 49 {1917), No. 3, pp. 110, HI).— The genera Elacherto- 

 domyia and Emersonopsis are erected. 



The privet mite in the South, E. A, McGbegoe {Jour. Econ. Ent., 9 {1916), 

 No. 6, pp. 556-561, pi. 1, fig. 1). — This paper relates to Tenuipalpus bioculatus
