Mr. Fereday exhibited some specimens of Nausibius dentatus, Marsham, bred 

 from the fruit of Dimocarpus Litchi received from China. 



Dr. Knaggs exhibited a small mutilated larva, apparently lepidopterous, respecting 

 which he communicated the following : — 



" A medical friend was called to see a child, ten years of age, who was suflFering 

 from vomiting of blood and passage of blood by stool. On examination of the 

 l)haryux he observed that blood was trickling from the posterior nostrils ; during the 

 examination the child expressed an inclination to sneeze, upon which a white 

 pocket handkerchief was applied, in order to see if any blood was thereby 

 ejected ; there was, however, nothing but mucus and the small larva produced, which 

 was alive at the time, but had since been crushed by accident." 



Dr. Knaggs observed that instances of insects being ejected from the nostrils by 

 sneezing had been previously recorded in the ' Proceedings ' of the Society. The 

 injured larva he now exhibited was probably that of Endrosis fenestrella, a very common 

 species everywhere in houses ; and he considered it not impossible that it was on the 

 handkerchief before the sneezing took place. 



Mr. M'Lachlan exhibited specimens of a trichopterous insect new to Britain, the 

 Gouiotaulius concentricus, Kolenati, not Phryganea concentrica, Zett. ; Stenophylax 

 vibex, Brauer, not of Curtis. Of this species about a dozen specimens were taken in 

 1860, near Ranworth, by Mr. Winter ; it is a common species on the Continent, and 

 variable, the typical specimens from Russia being smaller and darker than those of 

 Western Europe. 



Mr. Stainton exhibited cases of two species of the long-horned moths. One case, 

 which belonged either to the genus Adela or the genus Nemophora, was composed of 

 several pieces of brown leaves added in succession : the larvae inhabiting this sort of 

 case were feeding on withered oak-leaves. The other case, which probably belonged 

 to the genus Nemotois, was formed by successive additions around a brown oval 

 nucleus, and was much contracted in the middle: the lavvas inhabiting this case were 

 feeding on the green leaves of Ballota nigra. The Adela ? cases were found by Mr. 

 Healy, at West Wickham, by searching amongst the fallen oak-leaves. The Nemo- 

 tois? cases were collected by Herr Schmid, of Frankfort-on-the Maine, around plants 

 of Ballota nigra, the lower leaves of which were much eaten by them. 



Mr. F. Walker exhibited a large box of North-American Hemiptera, and made 

 the following remarks, which occurred to him while inspecting this collection : — " It 

 is well known what a great affinity part of the fauna of North America bears to that 

 of Europe ; and this likeness between the two faunas increases northward until they 

 become nearly identical ; and there are indications that the separation between the 

 eastern and western continents took place at a later period in the northern regions 

 than in the southern regions. The separation between the northern fauna and the 

 southern fauna is much less complete in the western countries than in the eastern 

 countries ; and this is owing to the divisions in the latter by means of seas and moun- 

 tains, which are comparatively wanting in the western continent. The fauna of the 

 Central Slates of North America and that of the eastern slope of the Alleghany moun- 

 tains appear to be equally similar to that of England ; and in the plains of the United 

 States the faunas of the north and of the south are comparatively mingled together, 

 whereas in the regions of the Old World they are nearly separate, and in the southern 

 part the northern fauna only appears on the mountain ranges. I will conclude by
