Exhibitions, dc. 



Mr. Butler exhibited an example of arrested development in a peacock 

 butterfly, bred from the chrysalis, caused by the tail of the pupa having 

 become detached during the process of emerging; the right wings were 

 completely developed, whilst the left wings had not developed at all, the 

 pupa-case remaining attached to the left side of the body of the butterfly. 



Mr. W. C. Boyd exhibited specimens of Solenobia inconspicuella, taken 

 in St. Leonard's Forest, and amongst them a specimen, taken at the same 

 time, of a remarkably pale colour, which might possibly be an albino variety, 

 but had a very different appearance from the ordinary form. 



Mr. Boyd also exhibited some leaves of the common comfrey {Si/mjihylicm 

 officinale), gathered at Cheshunt, the under sides of which were found to be 

 completely covered with specimens of Brachycentrus subnubilus. There 

 appeared to be some hundreds of specimens closely packed together, and 

 they were all dead, or in a moribund state, when found. All were said to 

 be males, but on close examination a single female specimen was discovered 

 amongst them. No explanation could be given as to the object of their 

 congregating together. Mr. Stainton remarked that there were many such 

 instances of a habit of congregating amongst insects, which were equally 

 unaccountable, and as an instance he mentioned a fact known to all breeders 

 of Micro-Lepidoptera respecting the pupation of the greater number of the 

 Nepticul®, the larv® of which live solitary as leaf-miners; but if a number 

 of leaves, containing larvte, are collected and placed together in a box, it is 

 found that the cocoons are constructed gregariously between certain leaves, 

 without any apparent reason for the preference.
