Exhibitions, dc. 



Mr. F. Bond exhibited a series of bred specimens of Acronycta tridens 

 and A. Psi, with preserved larvae of the two species. The specimens of 

 A. tridens had all been I'eared on the common pear. He remarked that 

 the dark specimens so often occurring in A.. Psi were never repeated in 

 A. tridens ; and that the latter always exhibited a pinkish tint in fine fresh- 

 bred specimens, which, however, was very evanescent. 



Mr. Miiller exhibited some cases of a species of Psyche, formed of 

 twigs arranged spirally, and also the egg-case of a species of Mantis ; these 

 had been sent from Calcutta by Mr. James Rothney. 



Professor Westwood exhibited two Dipterous larvse preserved in spirits 

 which were probably those of Psila rosae. These had been discharged by 

 a female in a clot of phlegm. He suggested when they were submitted to 

 him that the person had probably been eating raw carrots, which, upon 

 enquiry, turned out to have been the case. After they had been immersed 

 iu spirits for three or four days he took them out for examination, when he 

 was surprised to find they were still alive. He also exhibited drawings of 

 a dipterous larva (probably Merodon clavipes, Fab.) infesting some bulbs 

 sent to him from the Continent. Also drawings of woody excrescences on 

 stems of vine, which had probably been formed by a beetle of the genus 

 Otiorhynchus. Mr. Miiller remarked that Mr. Riley had recorded a similar 

 habit in an American beetle allied to Baridius. 



Professor Westwood further exhibited drawings of the root-fibres of a 

 vine, dilated and constricted in a joint-like manner, which he thought was 

 owing to former attacks of Phylloxera. 



Mr. Briggs exhibited parallel series of the large and small forms of 

 Auaitis plagiata taken by him in Tilgate Forest, iu the month of June, 

 stating that he had found only the larger form last year, in the same place 

 in which he had found only the smaller form three years before. It was
