Exhibitions, Sc. 



Mr. M'Lachlan exhibited a partially gynandromorphous specimen of Brachy- 

 centriis subuubilus, captured at Cheshunt by Mr. Boyd : the maxillary palpi 

 and the left fore wing were of the female form, whilst all the rest of the insect 

 was of the male form. (See Ent. Mo. Mag. vii. 19). This was only the 

 second instance of gynandromorphism in the Trichoptera which had come to 

 Mr. M'Lachlan 's knowledge. 



Mr. S. Stevens exhibited living specimens of Ateuchus semipunctatus from 

 Venice, one of them having been incarcerated for three weeks in a bottle with 

 bruised laurel-leaves, without any apparent ill effect. 



Mr. Albert Muller, after referring to the breeding by Herr Hartmann of 

 various Lepidoptera from gall-like swellings on the twigs of juniper (see Proc. 

 Ent. Soc. 1868, p. xv.), exhibited some stems of juniper from Godalming which 

 bore swellings, some of very large size, which were supposed to be caused by 

 insects. 



Mr. W. Warwick King (who was present as a Visitor) exhibited a miscel- 

 laneous collection of insects from Tugela, near the Drakenborg Mountains, 

 Natal. 



The Secretary exhibited a collection of insects sent to the Society by 

 Mr. Henry Ansell, from Ivinsembo, S. W. Coast of Africa. In the letter which 

 accompanied them, dated " Kinsembo, 23 Febry., 1870," the writer described 

 the insects as "captured in this locality: the Coleoptera of this coast are 

 certainly wanting, as I have on several occasions visited the most likely 

 localities and found next to nothing. I hope, however, within a few months to 

 visit Cabenda, where I believe I shall have better success." 



Mr. Butler mentioned that whilst looking through the volumes of Freyer's 

 Beitrage he had stumbled upon three plates illustrating the metamorphoses of 

 Argynnis Niobe and Adippe, and upon referring to the text he found some 

 interesting remarks on the possible identity of the two forms. He then read a 

 translation of a passage (Neuere Beitrage, vol. iii. p. 11), from which it 

 appeared that, though at one time firm in the belief that the two were distinct 

 species, Freyer's confidence in the correctness of that view was very much
