Exhibitions, <&c. 



Mr. Bond exhibited several species of Lepidoptera taken in Perthshire, 

 last season, by Mr. Eedle, viz. Pachnobia alpiua, being the third known 

 British example ; a fine variety of Larentia cresiata ; a very dark form of 

 Thcra juniperata, being its ordinary condition in that district, and remark- 

 able also for the time of its appearance, which was nearly two months 

 earlier than in England; Gelechia boreella; and finally Hyponomeuta 

 evonyraella, L. fpadi, Zcller), the larva of which Mr. Eedle had observed to 

 cover the trees of bird-cherry with its webs to a remarkable extent, — a piece 

 of web exhibited was a yard long. 



Mr. Bond also cxliibited an example of Vanessa Atalauta, bred by 

 Mr. Jackson, which still retained the larval head. 



Prof. Wcstwood said that this form of monstrosity was very rare. Ho 

 could call to mind only four recorded instances : (1) Nymphalis populi, 

 (2) Gastropacha quercifolia and (3) Dytiscus margiualis in the British 

 Museum, and (4) a Syrphus in the Oxford Museum. 



Mr. Bond laid before the Meeting some beautifully executed photographs 

 of the eggs of bird parasites, taken from microscopic slides, prepared by 

 Mr. Norman, of 178, City Road. 



Mr. Miiller exhibited several galls, collected by Mr. Trovey Blackmore 

 in Morocco, as follows : — 



Firstly. On the cork tree {Qtiercus subcr), a monothalamous, terminal, 

 bullet gall, standing on a peduncle of an inch in length, emanating from a 

 thin twig: colour dark gray, with irregular fuscous veins ; surface rough, 

 greatest diameter 15 mill. Undoubtedly the home of a true Cynips. 

 Mr. Blackmore informs me that he " cut it from a cork tree, near Cape 

 Spartel : many others were on the same tree." 



Secondly. On an undetermined species of oak {Qiierciis ?} ; on the 



under side of a leaf, and attached to the lateral ribs. A. — Monothalamous, 

 pea-shaped, flattened galls : ground colour mahogany-brown, irregularly 

 sprinkled all over with small darker spots, some of which are reddish and 

 ocellate, with a pale dot in the centre ; surface more or less polished and 

 shining (four specimens) ; size variable ; greatest diameter of the largest 

 specimen 15 mill ; of the smallest 6 mill. These galls show great affinity 

 to those of Cynips agama, Hartig. B. — Deeply wrinkled, flat, brownish 

 spangles seated right across the lateral ribs ; greatest diameter 5 mill. If 

 not a very immature stage of the gall A, these spangles may belong to a
