 xlvii, Feb. 1914, p. 69. 



In view of the disease-bearing potentiality of the house-fly, Muscd 

 domestica, it is important to know more of its hibernating habits, a 

 matter upon which writers are not agreed. Dr. Skinner in America 

 stated that house-flies pass the winter in the pupal stage and in no 

 other way, a conclusion at variance with results obtained in England 

 by Newstead and Jepson. It is a c[uestion that has been taken up 

 for investigation by the Local Government Board, which undertakes 

 to have specimens of hibernating flies identified. In the present note 

 the author writes with a view to soliciting help and interest in the 

 work : flies hibernating in attics and other unoccupied rooms, in chinks 

 and crannies of living rooms and in stables, barns and other outbuild- 

 ings close to houses, should be collected and sent to Dr. S. Monckton 

 Copeman, F.E..S., Local Government Board, AVhitehall, S.W., or to 

 the author, British Museum (Natural History), Cromwell Road, London. 



Le Cr^syl insecticide. [Cresyl as an insecticide.] — Bull. Soc. Etude. 

 Vulg. Zool. Agric, Bordeaux, xii, no. 6, Dec. 1913, pp. 179-180. 



A short note deals with the investigations of Bouet and Roubaud 

 into the antiseptic and insecticidal properties of cresyl. These 

 workers have demonstrated the efficacy of this product for destroying 

 flies, mosquitos, fleas, etc. Cresyl fumes almost immediately stupefy 

 the insect, and if the latter should revive, very marked lesions prevent 

 its doing injury. A slight increase in the dose or a slightly prolonged 

 time of contact leads to death. Flies and mosquitos, even if hiding 

 in folds of canvas or in wickerwork, succumb rapidly to a dose of 75 

 grains per 35 cubic feet. This strength does not affect man or other 

 mammals, so that the fumigation does not bar access to the rooms 

 in which it is being carried out. The only trouble is a slight irritation 

 of the conjunctiva. During the whole of the experiments Bouet and 

 Roubaud were able to keep white rats in the rooms treated without 

 observing any morbid symptom. The fumes do not injure household 

 articles, metals, or gilding. The air need not be artificially agitated 

 as cresyl is extremely volatile. These experimenters hold it to be the 

 surest remedy for the rapid disinfection of insect-infested buildings, 

 while it is at the same time an excellent and cheap antiseptic.

In September 1913, the authors undertook an expedition in the 

 forest country of the State of Sao Paulo for the purpose of discovering, 

 if possible, the host which transmits American forest Leishmaniasis. 

 This disease which has been known for a long time and has been called 

 by various names, pian-bois, forest-yaws, bouton de Bahia, etc.,
