The Ceutorliynchiis sulcicollis, or turnip-gall weevil, is, 

 perhaps, of no very great importance in its attack on turnip 

 roots, as except when in unusual quantities the galls it gives 

 rise to can be used for sheep food like the rest of the root, 

 though the quality of the bulb suffers materially. With 

 the cabbage it is a different matter, here its attack is some- 

 times a serious injury; and the enormous extent to which it 

 exists in some of our cabbage-growing districts, both in 

 England and Ireland, make its habits of some degree of 

 interest. 



The small, black-gray weevils, scarcely more than a line in 

 length (and from their habit of feigning death when alarmed, 

 eluding all but the most careful search), are well known, and 

 appear in the specimens I have reared from larva) taken out 

 of galls on the cabbage or common while turnip roots, to be 

 exactly similar in both cases. The pupaj, also, have precisely
