LUCUSTS.

ment, from date of hatcliiug to maturity, is given in the cases recorded 

 regarding Acridium americanum as being seventy days. 



With regard to this country, it is probable that from climatal, as 

 well as other considerations, there is not the least cause to fear 

 establishment of this infestation ; still as the observation of these 

 great insects necessarily attracts much attention, and sometimes not 

 unnatural apprehension, and as with the increasing amount of im- 

 portations of human food and cattle fodder it is probable their 

 presence will be more frequently observed, it has seemed perhaps 

 desirable to give a few notes in connection with the insect observations 

 of 1898. 



Note. — Those who wish to follow up the subject will find enormous 

 masses of information on almost every point connected with Locust life- 

 history, whether Entomological, Geographical, Meteorological, or 

 Historical, with methods of prevention and remedy, in the large 

 volumes entitled respectively ' First, and Second, Annual Keports of 

 the U.S.A. Entomological Commission, "Washington ' ; also in Appendix 

 xxvii., pp. 273-279, of 1st Eeport above named, will be found biblio- 

 graphical references. Much information will also be found in successive 

 reports of the State Entomologists of the U.S.A. Information on the 

 "Locusts of Bengal, Madras, Assam, and Bombay," will be found in 

 the ' Indian Museum Notes,' Calcutta, prepared by Mr. E. C. Cotes, of 

 the Indian Museum ; and inany short notices of observation of appear- 

 ance of Locusts in Great Britain will be found by reference to indexes 

 of the ' Entomologist's Monthly Magazine.'
