Mr. B. Adkin exhibited examples of Pachygastria (Bonibyx) 

 trifolii and contributed the following note : 



"The examples of Bonibyx or Pachygastria trifolii shown 

 comprise six of the pale variety, probably ab. flava (Tutt), 

 and two of the darker variety, possibly ab. riifa (Tutt), which 

 perhaps show something like the two extremes of the varia- 

 tion in the colouring of the species found in England. Some 

 in Mr. Woodforde's collection were from the N.-W. Coast, 

 and of a colour intermediate between those shown. I con- 

 sider this an interesting insect, from its showing so much 

 variation even in the same locality." 



The very dark c^ and 5 were bred from larvae taken in 

 Scilly, while the pale c?s and ?s were bred from Kent 

 larvae. Several members testified as to their want of success 

 in breeding this species from the egg. 



Mr. Main exhibited photographs of Gonepteryx cleopatra 

 received from Dr. Chapman, Nyssia hispidaria, from Epping 

 Forest, the larvae of Selcnia bihinaria, and imagines of 

 Endromis versicolor, and Lcncophasia sinapis. 



Mr. Moore exhibited a fish taken from the Thames, which 

 was said to be a salmon. It was, however, identified as a carp. 

 It weighed about ij lbs., and was caught off Rotherhithe. 



Mr. Manger exhibited a beetle, Homopliceta nlbicollis, taken 

 on a steamer by his son while cruising among the West 

 Indian Islands, where it is generally distributed. 



Mr. Step exhibited specimens of the British saxiirage 

 Chrysosplcnium oppositifoliuui from Westcote, Surrey. 



Mr. Main exhibited ova of Colias ediisa, var. helice, laid by 

 a female specimen sent to him from Hyeres by Dr. Chapman. 

 They were deposited either singly or in small batches. In a 

 short time they changed from white to a bright red, and in 

 one stage were prettily variegated. They were deposited 

 upright on a glutinous, pellucid base. 



Mr. Manger exhibited a large number of shells of the 

 family Spondylidas, to illustrate his paper on this section of 

 the Mollusca (see page 14). The President and others took 

 part in the discussion which followed.
