Mr. S. Stevens exhibited a moth, Orthostixis catenaria, Hubn., a North American 

 species, and a letter from Mr. Hemming, of Brighton, was read, stating that it 

 came from the collection of Mr. Thorncroft, who believed he took it at Eastbourne. 



Mr. Stevens also exhibited two specimens of the New Holland Longicorn beetle, 

 Phacodes Mossmanni, Newman; and a Curculio from Brazil, with some spine-like 

 fungi attached. 



The President said that on examining some seed-pods of furze, he found in one, 

 besides specimens of Oxystoma Ulicis, a cocoon, in which was a grub belonging he 

 thought to some Hymenopterous parasite upon Oxystoma. In a seed-pod of Lathyrus 

 pratensis he had lately found a larva and a pupa, which had not yet been perfected, 

 but which he imagined were those of an Apion. 



Mr. Douglas exhibited a stem of common dock, containing larvae of a Pemphredon 

 or Cemonus, placed one above the other at the bottom of a burrow about four inches 

 long, at the top of which was a hole by which they would make their escape when 

 perfect, and which was now closed by whitish papery film. 



The President read the following descriptions of two new butterflies, and the cha- 

 racters of the new genus he proposed for Papilio Telamon, Donovan.

 horizontaliter porrecti ; hirti nee setis longis ut in Thaide instructi ; antennae 

 vix clavatse, articulis circiter 30 sensim incrassatis, articulis 10 ultimis paullo 

 brevioribus. Ala? anticag triangulariter ovatae apice rotundatae, vena post-costali 

 4-ramosa ramis simplicibus, lmo et 2do ante apicem areae discoidalis emissis, 

 3tio ad ejus apicem emissa, 4to in medio spatio inter apicem areae discoi- 

 dalis et apicem alae ; vena disco-cellularis supera brevissima ; media multo 

 longiori in medio augulata angulo versus basin alarum spectanti ; vena disco- 

 cellularis infera breviori, cum apice venae medianae fere continua, et spatio 

 inter hujus ramos 2dum et 3tium longitudine fere equali. Alae posticae subo- 

 vales, margine externo vix repando ramo tertio venae medianae in caudam lon- 

 gissimam at valde angustam producto ; vena praecostali apice furcata, venae
