 Mustard Beetle.

Besides the above-named beetles, a small dark-grey long- 

 snouted beetle, commonly called the " Turnip Weevil " (a 

 kind which destroys the seeds of various plants of the 

 Cabbage tribe when they are formed in the pods), was also to 

 be found, together with the flower-beetles on the blossoming 

 heads ; scientifically, this is the Ceutorhynchus assimilis. 



Cetitorhynchus assiviilis, Payk. : Beetle, maggot and chrysalis, nat. size and 

 magnified. Infested Turnip-pod. 



ONION. 



Onion Fly. Anthmni/iK ceparum, Bouche. == rhorbia cepetoruin, 

 Meade. Shallot Fly. Antlwmyla platnra, Meigen. 



The injury in this case is caused by the maggots of the 

 Onion Fly feeding inside the Onion-bulbs, which partly from 

 the quantity gnawed aAvay, and partly from the decay caused 

 by the workings, are often completely destroyed.
