A brief account is given of the life-history of PI atyparea poeciloptera 

 Schr. (asparagus fly) in France. The damage caused by it and the 

 remedial measures advocated are outlined, Lesne's observations 

 being extensively quoted [R.A.E., A, ii., 403 ; iv, 304].

This paper is based on observations made in Guatemala in 1914 

 following the devastating locust invasion that occurred at the end 

 of 1913 during a period of extraordinary drought. In 1914 rainfall 

 coincided with an extensive mortality of the adults of Schistocerca 

 peregrina, which was found to be largelj^ due to parasitism by Dipt era. 

 The flies found were Muscina stahtdans, a new Tachinid, the Phorids, 

 Aphiochaeta scalaris, Lw., and other species of this genus, and an 

 Anthomyiid, Fannia canicularis, L. It is not known whether the 

 Tachinid is a cosmopolitan species, and a suggestion is made that its 

 acclimatisation should be attempted in other countries so as to ascertain 

 whether other gregarious and migratory locusts, such as 5. paranensis, 

 S. peruviana and 5. americana, are attacked by it.

In 1917 the pink boilworm of cotton [Platyedra gossypiella, Saund.J 

 appeared in the Laguna district of Mexico. On 15th November 1917 

 the Mexican Secretariat for. Agriculture issued an order, based on the 

 Federal Law of 21st December 1909, declaring the limitation and 

 destruction of P. gossypiella to be a matter of public utility, prohibiting 

 the transport of cotton seed and lint from the Laguna region to localities 

 outside, fixing the limits of the infested area, requiring such transport 

 within the infested area to be effected in closed cars reserved solely 

 for these materials, permitting the export of ginned cotton subject 

 to its disinfection if that measure be thought necessary by the 

 authorities, and fixing penalties for non-compliance with these 

 requirements. On 15th December 1917 regulations were issued 

 requiring inter alia the destruction of all cotton debris in the fields 

 after the harvest and of all the roots of cotton and of the grasses round 

 the fields, requiring the disinfection of all store-rooms, requiring all 

 seed, lint and cotton to be fumigated with carbon bisulphide at the
