EcjJOrtcd Colorado JJrrfIr at UitrhUy. 



Some pup.T sent from Hockley were those of tlie 7-spotte(l La<ly- 

 binl (C scjUcmpunctata). 



There are no records of any of the true Ui<ly-l»ir<ls, except a 

 single si>ecies of SubcocciiicJla, S. xiyintiquatnorpuactitUi, Linn., doing 

 any harm to lV)liage in this country, hut many «»f the large genus 

 EpUachnu, which does not occur here, do considerable liann, and are 

 all herbivorous and not carnivorous. It is extremely improbable 

 that the potato leaves sent by Mr. Craigie, which ai)pear to l)e 

 devom'ed to some considerable extent, have been attacked by the 

 Coccinellids sent. It is much more likely that " Surface Larvie," 

 wliich are nocturnal feedei-s, were the cause of the damage, or slugs. 



At the same time, it is of com-se not impossible for carnivorous 

 insects to develop herbivorous habits. Search should l^e made on the 

 potatoes for Plant Lice, the normal Lady-liird food ; if none occur, 

 then there would be more reason to think that the larval Coccinellids 

 bad become herbivorous. 



Sujiposcd Colorado Beetle at South Bcnfiect. 



Tupie sent from South Benfleet as Colorado beetles were these 

 of the 7-spotted Li\dy-bii-d (C. scptempiuictata), 



Susjyeded Colorado Beetle at North fleet. 



Pupa? also sent from Northfleet were those of the 7-spotted Latly- 

 bird (C. septempunctata), and not any stage of the Colorado Beetle. 

 Nothing was found in the tube resembling Fig. 2 of the pamphlet, 

 ])ut the pupa^ are those figured at No. 7. 



Tliere was also .sent a small atlull I>4idy-bird {Ilippodamia 

 rariegata). 



BOOT CKOr BKSTS. 



The Cabbage Aphis on Turnips. 



A con-espondent forwarded in September some liirni]) leaves 

 seriously damaged by aphides from tlie Isle of Thanot. The leaves 

 were attacked by the Cabbage Aphis (Aphis brassirn-, Linn.) Nothing 

 can, of course, be done as late as tiiis ; as a nde the Ichneumon flie-s 

 ])arasitise them in enormous numbers in Sopteml>er. It is not 

 known for certain how they pas,s the winter — but pmbably in the 

 egg-stAge on wild Crucifene. This species d<>os not usually attack
