852 EXPERIMENT STATION RECORD. 



The cotton-boll weevil in Cuba, G. X. Wolcott (Proc. Ent. Hoc. Wash., 16 

 {1914), ^0. 3, pp. 120-122). — Observations made in Cuba duiing the winter of 

 1911-12 sind again during January and February, 1914, sbow that but little 

 injury was done by the boll weevil. No boll weevils were found on cotton at 

 Kinji.stou, Jamaica, in March. 1914. 



A braconid parasite on the pine weevil, Hylobius abietis, J. W. Munbo 

 {Ann. AiJijl. Biol., 1 {WUt), A*o. 2, pp. 110-11(), figs. //).— A report of observations 

 made oil pine weevils and parasites collected in a plantation near Aberdeen. 



This weevil is a source of injury in the adult stage only, doing considerable 

 damage by gnawing the tender bark of young conifers and thus causing them to 

 wilt and die. In the absence of conifers, it will readily attack birch, mountain 

 ash, and oak. The author's observations indicate that Bracon hylobii may 

 prove of considerable value in combating the weevil, which every year is becom- 

 ing more and more common in newly formed plantations, especially in Scotland. 



A revision of the North Anaerican species of the braconid genus Habro- 

 bracon, li. A. Cushman {I'ror. Ent. 8oc. Wash., 16 {191.',), No. 3. pp. 99-108).— 

 Seven species are recognized of which Uabrobracon variabilis, reared from 

 Canarsia hammondi, at Siloam Springs. Ark., and //. platynota: from Plati/nota 

 sp., at Hollywood, Cal., are described as new to science. 



Descriptions of new chalcid flies, A. A. Girault {Proc. Ent. Sac. Wash.. 

 16 {191. 'f). No. 3, pp. 109-119). — Among the parasites here described as new is 

 Anaphoidea luna, a species obtained in shipments of the alfalfa weevil {Phy- 

 tonoinus posticus) from Italy. 



Some notes on Xyleborus fornicatus (shot-hole borer), A. Rutherford 

 {Trop. Ayr. [CeyJon], Jt2 {191 J,), Nos. 2, pp. 132-139; 3. pp. 220-222) .—The 

 burying of prunings from tea plants is said to have been the prevailing method 

 applied in the control of A. fornicatus. Upon looking into the subject the 

 author was able to find but a single experiment relating to their destruction 

 in this way and was led to conduct the several tests here reported upon. 



Nine in. of fine earth was not a formidable barrier to the emergence of the 

 beetles. Slaked lime failed to kill even the larvae after an exposure to it for 

 23 days. It was found that under laboratory conditions the beetles will con- 

 tinue to breed in prunings that are far gone in decay, provided these are not 

 too dry, and even in the presence of slaked lime or quicklime, and that they are 

 able to work their way up through as much as 7.5 in. of fine earth. Not only 

 the adults but even pupae may remain alive in prunings left on the surface of 

 the ground for as many as 13 days. 



" In the light of our present knowledge the only means of control that can be 

 recommended are. from an entomological point of view, (1) burning of primings; 

 (2) discovery of and elimination of, as far as practicable, breeding grounds in 

 plants other than tea; (3) cultivation and manuring; and (4) prevention, so 

 far as possible, of the infestation of fresh areas." 



Descriptions of two parasitic Hymenoptera, S. A. Rohweb {Proc. Ent. Soc. 

 Wash., 16 {Wl.'i), No. 3, pp. I'/l, l.'f2). — Sympkerta mnemonics, a primary para- 

 site on Mnemonica avricyanca on chestnut and oak at Falls Church. Va. ; and 

 Podogaster evetrivorns, a parasite of Evetria sp.. on Pinus pondcrosa at Fort 

 Bayard, N. Mex., are described as new. 



Third annual report of the state bee inspector to the governor of the 

 State of Iowa for the year 1914, F. C. Pellett {Ann. Rpt. State Bee Insp. 

 iloxca, 3 {1914). pp. l'^6. pi. 1. Jigs. 63). — This report of the work of the year 

 includes the proceedings of the meeting of the Iowa Bee Keepers' Association, 

 lield at Ames, November 17-19, 1914, and the papers presented, namely. Short 

 History of Bee Keeping, by C. P. Dadant (pp. 32-37) : Temperature and 

 Humidity in the Wintering of Bees, by E. F. Phillips (pp. 37-56) ; Wintering
