102 THE ENTOMOLOGIST. 



should like to hear the Rev. J. Greene, Mr. Doubleday or 

 Mr. Birchall on the subject. I presume Mr. Gibson has 

 Mr. Greene's ' Insect Hunter's Companion ;' it enters fully 

 into matters of this kind. — Edward Newman. '\ 



47. Geophitus electriciis. — Can you give me any informa- 

 tion of the following creeping insect ? It was an inch and a 

 half long, and about as thick as small string. It was of a 

 light stone-colour, and had legs all along its body, and two 

 antennae. It gave a rather brighter light than the glow- 

 worm, and when taken up my fingers glowed with phospho- 

 ric light. — Albert Dumsday ; Talbot Hotel, Cuckjield, Oc- 

 tober 5, 1864. 



[It is a uiyriapod, and not properly an insect. The name 

 is Geophilus electricus, so called from the appearance of 

 electric light which it emits when trodden on. — Edward 

 Newman .'] 



48. Pericallia Syringaria emerging in October. — Out of 

 about twenty-five larvae of Pericallia Syringaria, which were 

 all hatched in the space of twenty-four hours, one single 

 larva fed up rapidly, and became a pupa. It emerged a few 

 days since. Is it not strange ? The remainder of the larvae 

 are still small, and are beginning to hybernate. — William 

 Stewart ; Eldon Villa, Redland, Bristol, October 5, 1864. 



49. Larva of Acronycta Aceris. — Mr. J. Sarson, of this 

 town, brought me a caterpillar, which he had taken feeding 

 upon oak, for identification. As I have never seen one like 

 it before, nor remember to have seen the figure of it in any 

 publication I have had access to, I have made three drawings 

 of it for your examination. Will you kindly say, in the next 

 'Entomologist,' what species it is? — Edwin Tearle ; The 

 Crescent, Leicester, October 9, 1864. 



[The larva is that of Acronycta Aceris, described at page 

 43 of the 'Entomologist:' I have rarely obtained it from 

 oak, but it is by no means uncommon on Acer Pseudo-pla- 

 tanus (sycamore) in August and September. — E. Neivman.'\ 



50. Entomological Society, September 5, 1864. — Mr. Dun- 

 ning exhibited a number of lull-fed larvae of a Noctua (Agrotis 

 Segetum, or A. exclaraationis .''), which had been sent to him 

 by Mr. J. D. Kay, from Brantingham, in the East Riding of 

 Yorkshire. Mr. Kay had had a field of turnips, worth ^150, 

 entirely destroyed by these caterpillars. Numerous similar
