1076 EXPERIMENT STATION RECORD. 



small diameter are recommended as vessels in which to produce the gas. 

 There should be 1 jar for each 50 ft. in length of an ordinary green- 

 house. The cyanid of potash is weighed out and inclosed in paper 

 bags, which may be suspended by a string directly over the jars and 

 can be lowered from the outside of the greenhouse. An amount of 

 water should be poured into each jar equal to the amount of potassium 

 cyanid in the bag, or about I pt. of water to each 8 oz. of cyanid. 

 Sulphuric acid should then be added until the water steams. The 

 house should be tightly closed. The bags are then lowered into the 

 jars for the necessary length of time. The greenhouse should be ven- 

 tilated for at least half an hour before entering. 



Report to the Royal Ministry of Agriculture concerning work of the State 

 entomological department for the year 1898, S. Lampa {Ent. Tidskr., 20 (1S99), 

 Xo. 1, pp. 70)- — Contains notes on a large number of economic insects and their 

 injuries in Sweden, including ArgyrestMa conjugella, Cecidomyia destructor, and C. 

 tritici. 



Insects collected on Mount Fugi, M. Matsumura (Annotationes Zool. Japonenses, 

 2 {1S0S), pt. 4, pp. 113-124). — Gives a considerable list of insects .which are noted 

 as occurring in zones at different elevations on the mountain. 



Acclimatization of beneficial insects (Rov. Lapok, 6 (1899), Xo. 4, pp. 88). — Teda- 

 lia cardinalia from California has been successfully introduced into the Sandwich 

 Islands. 



A serviceable insectary, F. M. Webster ( Canad. Ent., 31 (1899), Xo. 4, pp. 73-76).—

The common blue tick of Cape Colony and its relationship to the red water 

 ticks of North America and Australia, C. Fuller (Agr. Jour. Cape Good Hope, 

 14 (1899), Xo. 6, pp. 363-369). — Contains an analytical table of the species of Rhipi- 

 cephalus. The American Boophilus hovis is called It. aunulatus and the local blue tick 

 of the colony is called It. decolor atus. The latter, like the American species, carries 

 red water from animal to animal. 



Codling moth, C. P. LOUNSBUBY (Ayr. Jour. Cape Good Hope. 14 (1899), No. 5, pp. 

 285-287). — Reminds fruit growers of the dangers from this insect in the colony. 



A new rival of the codling moth, E. Reuter (Ent. Tidslr., 20 (1899), Xo. 1, pp. 

 71-76). — Argyresthia conjugella is described, with an account of its life history and 

 distribution and its injuries to the apple. 



Phylloxera, L. de Sisterxes (Bol. Agr. Min. Intl., Mexico, 8 (1898), Xo. 4, pp. 

 11-39). — The article contains an account of the life history, habits, and injuries 

 resulting from the phylloxera, together with a description of the insect in its various 

 stages. As remedies the author suggests pulling out the weak vines, flooding the 

 vineyard, the use of insecticides, destruction of winter eggs, rearing its insect 

 enemies, planting in sandy soil, and the use of American varieties. 



Some notes on the grape-cane gall maker (Ampeloglypter sesostris), F. M. 

 Webster (Ent. Xews, 10 (1899), Xo. 3, pp. 53-55, pi. 1). — Notes on the habits of this

Seasonal dimorphism in Lepidoptera, Roland Trimen (Xature, 59 (1899), Xo. 

 1537, pp. 568-573). — The author considers this phenomenon in a large number of spe- 

 cies, and suggests the establishment of zoological stations for studying the subject. 



Investigations on the accelerated development of hibernating butterfly pupae,
