Reported Colorado Beetle at Hockley . 
Some pupie sent from Hockley were those of the 7-spotted Lady- 
bird (C. septempunctata). 
There are no records of any of the true Lady-birds, except a 
single species of Subcoccinella, S. vigintiquatuor punctata, Linn., doing 
any harm to foliage in this country, but many of the large genus 
Epilachna, which does not occur here, do considerable harm, and are 
all herbivorous and not carnivorous. It is extremely improbable 
that the potato leaves sent by Mr. Craigie, which appear to be 
devoured to some considerable extent, have been attacked by the 
Coccinellids sent. It is much more likely that “ Surface Larvm,” 
which are nocturnal feeders, were the cause of the damage, or slugs. 
At the same time, it is of course not impossible for carnivorous 
insects to develop herbivorous habits. Search should be made on the 
potatoes for Plant Lice, the normal Lady-bird food ; if none occur, 
then there would be more reason to think that the larval Coccinellids 
had become herbivorous. 
Supposed Colorado Beetle at South Benfieet. 
Pupae sent from South Benfieet as Colorado beetles were those 
of the 7-spotted Lady-bird (C. septempunctata). 
Suspected Colorado Beetle at North fleet. 
Pupae also sent from Northfleet were those of the 7-spotted Lady- 
bird ( C. . septempunctata), and not any stage of the Colorado Beetle. 
Hothing was found in the tube resembling Fig. 2 of the pamphlet, 
but the pupae are those figured at No. 7. 
There was also sent a small adult Lady-bird (. Hippodamia 
vccriegata). 
BOOT CHOP PESTS. 
The Cabbage Aphis on Turnips. 
A correspondent forwarded in September some turnip leaves 
seriously damaged by aphides from the Isle of Thanet. The leaves 
v ere attacked by the Cabbage Aphis ( Aphis brassicce, Linn.) Nothing 
can, of course, be done as late as this ; as a rule the Ichneumon flies 
parasitise them in enormous numbers in September. It is not 
known for certain how they pass the winter — but probably in the 
egg-stage on wild Cruciferte. This species does not usually attack
