ONION. 77 



somewhat triangular, rounded in front, and beneath the body, quite at 

 this extremity, are placed the two pairs of legs. 



Those who desire the fullest and best possible account of the 

 characteristics of this species will find it, accompanied by greatly 

 magnified figures of the male and female Mite, and also a sketch of 

 Mite-deformed buds, in the work by the great writer on this division 

 of Acarina referred to below.* 



The methods of prevention and remedy are on the same principle 

 as those for Black Currant Mite in respect of getting rid of the infested 

 Mite Galls ; but from the different method of growth of the Nut 

 bushes to that of the Black Currant, there must necessarily be some 

 difference in the details, as of pruning, &c., by which they are carried 

 out. All information available up to date regarding Phytoptus ribis, 

 and possible methods of prevention and remedy, will be found in the 

 Appendix to my Twenty-first Annual ' Report on Injurious Insects,' 

 pp. 141-158. 



ONION. 



Notes of considerable interest regarding maggots of the small 

 beetle Anohium jjaniceum, infesting Onion seed exported from England 

 to South Africa, will be found under the heading of " Seeds, Stores, 

 and Wood," some of the species of Anobium being very general feeders.
