whole matter was that they had been taken both in the spring 

 and autumn. As to the black males, which were taken in 

 different years, he could only say that in the course of his 

 experience, during which he had paid a great amount of at- 

 tention to this species, he had never seen or heard of anything 

 like it. 



Mr. South, who stated he had also paid considerable 

 attention to L. bellargtis, concurred with Mr. Weir in his

Mr. West, of Greenwich, exhibited two species of Coleoptera 

 from Shirley, Surrey — Balaninus rubidus, Gyll., and Erirhinus 

 pectoralis, Panz., — the former taken on birch, and the latter on

Mr. T. R. Billups exhibited a species of Hydradephaga, 

 Colymbetes fuscus, L., from which a Lepidopteron, most pro-

 case being firmly attached to the body of the beetle. 



Referring to this exhibit Mr. Billups said no doubt the 

 egg had been laid between the elytra, and after its emergence

This gentleman also exhibited specimens of the very 

 pretty and curious Birds'-nest fungus (Cyathus vernicosus), 

 found growing in his garden at Peckham.

 alboguttattis, Gr. (PI. 1, fig. 7), the former bred from Chcero- 

 campa porcellus, and the latter from Sphinx ligustri. Mr. 

 Billups stated that both species had been bred by Mr. R. 

 Adkin from larvae taken at Dartford, Kent, and that this
