The damage here reported took the form of eating away the paste 

 made of rye-floiir and dextrine, by which cornices and ceiling panels, 

 moulded in cardboard, had been fixed in position. The presence of 

 the mf)ths had been noticed while the work was in progress, and the 

 following year, on a length of the cornice being removed, no trace of 

 the paste which had filled the mouldings was to be seen, but in its 

 place were found larval excreta and innumerable empty pupa-cases.

This paper contains a popular account of the history and habits of 

 the fruit-fly, Ceratitis capitata, which is not at present a pest of any 

 importance in South America, but which, on account of its cosmopolitan 

 habits, is a potential danger to be reckoned with. The author suggests 

 that the following remedial measures should be undertaken without 

 delay, while the numbers are still unimportant. Dropped fruit should 

 be collected before the insects can enter the ground to pupate. The 

 use of various poisons to kill the flies is deprecated, as these destroy 

 bees and other useful insects at the same time. Experimentation 

 with natural parasites is suggested as being probably the most 

 promising method of control. It is suggested that the present scarcity 

 of C. capitata may be due to the presence of natural parasites, in which 

 case the discovery of these parasites might be used for the benefit of 

 other and more seriously affected countries ; while, if natural parasites 

 •do not occur, such species as Syntomosphyrum indicum, Dirhinus 

 •gijfardi and Galesus silvestrii might be introduced.

Several species of Muscids occur in the Argentine Republic that are 

 serious enemies of locusts ; the most important of these is Sarcophaga 

 caridei, Brethes, which is a specific and exclusive parasite of Sckistocerca 

 paranensis. The author advocates the propagation and use of this 

 species in the locust campaigns in that country. Brethes' description 

 of this fly is given and it is compared with, an allied species, Sarcophaga 

 acridiorum, Weyemb. The adult usually deposits a single egg on the 

 body of each locust, the total number produced by each female being 

 approximately 370 ; the larva upon hatching bores into the body of 

 the locust by perforating some spot where the integument is thin and 

 develops gradually at the expense of its host, without attacking the vital 

 organs until its development is practically complete; it then bores an 

 ■exit-hole and emerges and enters the soil to pupate, this stage lasting
