as a warning to birds never to touch these uneatable kinds, and a very 

 gaudy and conspicuous colouring, with the habit of fully exposing them- 

 selves to view, becomes such a signal, being in strong contrast with the 

 green or brown tints and retiring habits of the eatable kinds." (See also 

 Proc. Ent. Soc, March 4, 1867.)

Exhibitions, dc. 



Mr. J. W. Douglas exhibited a living specimen of Cerambyx Heros bred 

 from a log of wood imported from Bosnia ; also a young larva of the same 

 species from the same source. 



Prof. Westwood exhibited a number of cases constructed by the larva of 

 some species of Phryganea inhabiting Southern Europe. They were com- 

 posed of small semi-transparent quartz-like particles, and had been described 

 by Swainson in 1840 as a shell belonging to the genus Thelidomus, div. 

 Turbinea. 



Prof. Westwood also exhibited a specimen of a plant-bug {Capsidcs) which 

 had been sent to him by Mr. Alexander Wallace, together with the leaf of 

 an orchis {Cattleya Aclaiida), from Bahia. The leaf was covered all over 

 with blisters caused by the attacks of the insect. 



Mr. Jenner Weir exhibited a female specimen of Cicada montana, taken 

 in his presence in the New Forest by Mr. Henry Auld, who stated that he 

 was attracted to the spot where the insect was concealed by hearing it 

 stridulate. 



Mr. J. W. Douglas suggested that possibly the specimen caught did 

 not give rise to the sound heard, but that it was produced by a male 

 concealed near. 



Mr. Weir remarked that he had searched for the stridulating organ in 

 the specimen exhibited, and had found traces, although developed but 

 slightly in comparison with those of the male. 



Mr. S. Stevens exhibited two living specimens of Tillus unifasciatus, 

 taken near Norwood. They lly rapidly in the sunshine, and settle on 

 oak-piilings.
