The cotton culture of Brazil is one of the most important 

 occupations of the South American planters. The plants are, 

 however, attacked to a great extent by the mining larvse of a small 

 moth (Cemiostoma Coffeellum, Stainton), whose ravages and 

 economy have been investigated by Mr. B. Pickman Mann, " as 

 Entomologist to the Government of Brazil," by whom an inte- 

 resting memoir has been published in the ' American Naturalist ' 

 for June and October, 1872. 



The subject had been previously investigated by Messrs. Guerin- 

 Meneville and Perrottet, in a 'Me moire sur un Insecte et un 

 Champignon qui ravagent les Cafeiers aux Antilles" ('Revue 

 Entomologique,' 1842) ; by Herr Nietner, " Observations on the 

 Cotton Tree in Ceylon" (published at the ' Ceylon Times' Office, 

 1861) ; and by Mr. Stainton, "A few Words respecting Cemios- 

 toma Coffeella, an Insect injurious to the Coffee Plantations of 

 the West Indies" ('Entom. Weekly Intell.' 1861, vol. x.) 



The Report of the Entomological Society of Ontario for 1871 

 has recently been published, including reports on some of the 

 noxious and beneficial insects of the province, illustrated by 

 upwards of a hundred woodcuts. The insects affecting the apple, 

 the wheat crops and the cabbage, are described by the Rev. C. J. S. 

 Bethune, President of the Society ; those affecting the grape, the 

 currant and the gooseberry, have been undertaken by Mr. W. 

 Saunders, the Vice-President; whilst Mr. E. B. Reed has given 

 an account of the insects in connexion with the plum, potatoes, 

 cucumber, melon, &c. 



A ' Second Annual Report on the Injurious and Beneficial 

 Insects of Massachusetts' has also been published by A. S. 

 Packard, jun., M.D., which I have not j-et seen. 



Physiology. 

 A very curious physiological memoir on the position of the 

 centre of gravity in insects, has been published by M. Plateau, in 

 the ' Archives des Sciences Physiques et Naturelles,' torn, xliii. 



* It was on the 25th November, 1867, that my notice of this insect, described by 

 me under the name of Perityrabia vitisana, was communicated to the Ashmolean 

 Society of Oxford. This is here mentioned because an erroneous date is given by 

 Messrs. Planchon and Lichtenstein.
