Mr. M'Lachlan exhibited the eggs and young larvae of Ascalaphus 

 longicornis, found by Mons. E. L. Ragonot in the Forest of Lardy, not far 

 from Paris, apparently the northern limit of distribution of the species. 

 The eggs were arranged, after the manner peculiar in the family, in two 

 rows ou a dried grass stem, to the number of forty-six or twenty-three in 

 each row. He had some of the young larvae still living, but was uncertain 

 as to whether he would be able to rear them. 



Mr. M'Lachlan also exhibited, on behalf of Mr. Edwin Birchall, a much- 

 worn example of Heliothis scutosa, which had been captured by Mr. W. H. 

 Campbell, of Londonderry, in the north of Co. Donegal, Ireland, on the 

 19th August last. He alluded to the sporadic habits of this and allied 

 species, and its rarity in the British Islands. 



Mr. Rutherford exhibited, and communicated a description of, a new 

 species of Goliath beetle, from Mount Camaroons, allied to Geratorrhina 

 Sayi, Westw. He also exhibited a specimen of a West African butterfly, 

 Eomaleosoma Ruspina, Hew., nearly a third of the wings of which, on both 

 surfaces, along their outer margin, and beginning a little below the apical 

 angle of the primaries, were entirely destitute of scales, with the exception 

 of the nervures, which were sparsely covered with them. The symmetry of 

 the transparent portion of the naked wings seemed, he thought, to preclude 

 the idea that the butterfly had been partly denuded of its scales, either 

 intentionally or by accident; and he inclined to the conclusion that the 

 appearance it presented was due to some abnormal physiological condition 

 occurring either in the larva or chrysalis. 



Mr. G. C. Champion exhibited specimens of Amara infivia, from Chobham, 

 Surrey, this rare insect not having been recorded since 1^57, when Dawson 

 first added it to the list of British Coleoptera. 



Mr. W. A. Forbes exhibited a collection of insects from Switzerland, 

 taken at the latter end of June in a valley in the neighbourhood of 

 Chamouni, at an elevation of 5000 or 6000 feet.

Mr. D. G. Rutherford communicated a " Description of a new Goliath 

 Beetle from Tropical West Africa." The insect had been named Ccra- 

 torrhina Batesii. 



Mr. J. Wood-Mason read a note " On a Saltatorial Mantis," and exhibited 

 a specimen of the insect, which had been captured on the banks of the 

 Tagus. He also read notes " On the hatching period of Mantidce in Eastern 

 Bengal," and " On the presence of Stridulating Apparatus in certain 

 Mantida," this being the first discovery of such an organ in that family. 

 The author exhibited, in illustration of the last note, a large Mantis, showing
