 Meg.? found by Captain Parry at Tenby, and of Rhagium indagator, Callidium stri-

Mr. Douglas exhibited — 



Odontia dentalis, found on Echium vulgare at Folkstone, in July. 



Roslerstammia granitella, Xanthosetia inopiana, Eupsecilia udana ? and Sericoris 

 fuligana, Haiv., found on Inula dysenterica, also at Folkstone, in July. 



Adela Dumerillella? Tinea angusticostella, Pterophorus baliodactylus, Gelecbia 

 Coronillella and Argyresthia Sorbiella, the latter on Pyrus Sorbus (Service), at Mick- 

 leham, in July. 



Penthina ? in June, and Gelechia peliella, in August, at West Wickham. 



Depressaria atomella, and Catoptria ? in August, at Charlton Sandpit. 



Gelechia Inulella, Curtis, and G. bifractella, Mann, bred in July and August from 

 seed-heads of Inula dysenterica. 



Gelechia Carlinella, n. s., bred in August, from seed-heads of Carlina vulgaris. 



Gelechia, n. s., bred in August, from leaves of Cirsium lanceolatum, in which the 

 larva mines, feeding on the parenchyma only. 



Pterophorus lithodactylus, bred from leaves of Inula dysenterica. 



Mr. Westwood stated that in July, Lymexylon navale appeared from the oak- 

 timber in Pembroke Dockyard in thousands, and he had learned that they did not 

 continue in the perfect state longer than a fortnight, a circumstance he thought worthy 

 of note, as if availed of, their destruction might be more easily accomplished. The 

 experiment of placing the timber in the steam-tank for ten hours had been tried, 

 and found perfectly effectual in destroying the larva?. He was likewise informed that 

 the timber affected was quite sound when received four years since. Mr. Westwood 

 also stated that he had received specimens of Apate Capucina, a beetle that had done 

 considerable damage in the same dockyard to oak timber received from Istria. Ad- 

 verting to the case-making Lepidopterous larva? from pear-trees in the Horticultural 

 Society's Garden, exhibited at the meeting on the 3rd of June, Mr. Westwood said 

 they proved to be of two kinds, one having produced Coleophora nigricella, and the 

 other C. Hemerobiella. 



Mr. White read the following note on the boring powers of Monohammus 

 Sutor : — 



Messrs. Kirby and Spence in their world-read Introduction, record a striking 

 instance of the boring powers of another beetle of the Longicorn group, the Callidium 

 bajulum. Sir Joseph Banks gave to these gentlemen a piece of a sheet of lead, which, 

 though only eight inches long and four broad, was pierced with twelve oval holes, of 

 some of which the longest diameter is a quarter of an inch. 



In every case recorded, the lead has been over wood in which the larva or pupa 

 of the insect has been enclosed, and as insects in their unerring instinct generally 

 " go forward," the imago to get out to fulfil the object of its existence gnaws through 

 anything in the way, that can be reduced by its jaws. 



My friend Mr. Ainger lately had occasion to get a pipe repaired which had been 

 damaged by an insect ; the culprit is the Monohammus Sutor, and as Mr. Ainger 

 describes the circumstances well, I add his letter. 



" Dear Sir, — I send you the creature which perforated my leaden pipe, and the 

 enclosed sketch will explain the position of the pipe in reference to the round hole
