pupal period lasts about five days. At Ithaca, N. Y., there are at least two 

 generations and under very favorable conditions there may be three. 



Its predatory enemies are usually common and its parasites are thought to be 

 numerous. As regards control measures it is pointed out that the removal of 

 the bark will cause the death of all larvae and pupae and if it is burned im- 

 mediately after removal many adults will also be destroyed. Removal and 

 burning of the bark in winter where the adults are known to be in hibernation 

 will do much to lessen attacks in the season following. Where water is available 

 the placing of newly felled logs in it will pi'event injury by the beetles. 



Mention is- made of several common associates. 



Biological notes on Ceutorhynchus marginatus, S. W. Feost {Jour. N. Y. 

 Ent. Soc, 2Jt (1916), No. 4, pp. 243-253, pis. 5).— The author has found the 

 larvfe of this weevil to feed on the ovules and seeds of the dandelion at Ithaca, 

 N. Y. The species is common throughout Europe but has been found in this 

 country only in the Northeastern States. 



On some weevils attacking orchids, G. C. Champion (Ent. Mo. Mag., S. ser., 2 

 {1916), No. 21, pp. 200-202) .—Under the name Cholus caUleyce the author de- 

 scribes a new weevil which attacks orchids {Cattleya gigas) grown in a green- 

 house in Bergen County, N. J., and at Milwaukee, Wis., that originated in 

 tropical America. This appears to be the same species as that described by 

 Barber in the paper previously noted (E. S. R., 36, p. 360). A second species 

 described as new to science, Diorymellns Icevimargo, found attacking orchid roots 

 in a greenhouse at Ithaca, N. Y., and in Bergen County, N. J., feeds on the 

 leaves and flowers of orchids as well and also attacks the flowers of Dendrobiura. 

 This weevil also appears to have come from tropical America. 



Some unusual orchid insects, H. B. Weiss {Ent. News, 28 {1917), No. 1, pp. 

 24-29, pis. 2). — Among the unusual species which have been found associated 

 with orchids in New Jersey greenhouses are two weevils described by Champion 

 and by Barber as noted above. 



A survey of beekeeping in North Carolina, E. G. Cabk {V. S. Dept. Agr. 

 Bui. 489 {1916), pp. 16). — This is a report of a survey made in 19 counties in 

 North Carolina from October 1 to December 22, 1915. It was made with a view 

 to determining the present conditions, possibilities, and needs of the business of 

 beekeeping, with special reference to the best means of supplying the needs. 



The author has found that the State has a large number of bees, pollen and 

 nectar-producing flora in abundance, and the honey when properly produced is 

 of high grade and there is a good market for it. It is thought that extension 

 work in beekeeping should be inaugurated as quickly and carried on as vigor- 

 ously as circumstances will permit. 



The control of ants in dwellings. — A new remedy, A. Gibson {Canad. Ent., 

 48 {1916), No. 11, pp. 865, 366).— The author has found sodium fluorid to control 

 satisfactorily the common carpenter ant {Camponotus pemisylvanicus) and the 

 common shed-builder ant {Cremastogastcr lineolata) in buildings. 



Descriptions of various chalcidoid Hymenoptera, with observations, I and 

 II, A. A. Girault {Ent. News, 27 {1916), Nos. 5, pp. 223-228; 9, pp. 401-405).— 

 Among the 12 species described as new are Pseudomphale ancylce reared from 

 Ancylus nubeculana, Winchester, Va. ; P. steirastomw reared from larvae of Stei- 

 rastoma depressum, Erin, Trinidad ; Holycencyrtus physokermis reared from 

 Physokermes picea, Madison, Wis. ; Xenocrepis mexicana, parasitic on a scymnid 

 larva which preys upon Lecanium ole<B on orange at San Luis, and also from 

 the larva of Asya orMgera at Monterey, Mex., in the first paper; and Cocco- 

 phngns aleurodici reared from Aleurodicus on Theobroma bicolor, Trinidad;
