Insects. 4037 



Note on Lepidoptera bred from Larva. — I have lately bred the following insects 

 from larvae taken by myself last summer: — 



Notodonta trepida, two, larva; beaten off oak in July, Herts. 

 „ Chaonia, two, larva; beaten from oak in July, Herts. 



„ Dromedarius, three, from larva; on birch in September, Derbyshire. 



„ Dictaea, four, from larva; on poplar, Herts and Derbyshire. 



„ Ziczac, two, ditto. 



Pterostoma palpina, three, from larvae on poplar, Herts. 

 Ceropacha ridens, one, from a larva beaten off oak in July, Herts. 



„ Or, one, ditto. 

 Dianthaecia carpophaga, five, from larvae on seeds of Silene inflata, July and Au- 

 gust, Herts, Bucks, and Derbyshire. 



„ Cucubali, five, from larva; on Silene inflata, July and August, Herts, 



Bucks. 



„ capsincola, three, from larvae on seeds of Lychnis dioica, August, 



Derbyshire. 



Thyatira batis, two, from larvae on raspberry, July, Herts. 

 Acronycta Ligustri, one, from a larva on ash, July, Herts. 

 Eurymene dolabraria, one, from a larva beaten off oak in July, Herts. 

 I have also bred, but unfortunately in too deformed a state to be of any use, Dian- 

 thaecia conspersa, from a larva found on seeds of Lychnis dioica in Derbyshire; and 

 Platypteryx falcula from larvae on birch, in September, in Derbyshire. — H. Harpur 

 Crewe ; 17, Cavendish Road, St. Johns Wood, June 18, 1853. 



Captures of Lepidoptera at Chorley. — I have lately taken four specimens of Dian- 

 thaecia? conspersa, three sitting on trees, the other on a Rhododendron ; also Deilephila 

 Elpenor, Hadena gemina, Cucullia umbratica, Abrostola triplasia, Plusia Festucae, 

 Iota, inscripta, and many other common Noctuae. — E. C. Buxton, jun. ; Adlington 

 Hall, Chorley, Lancashire, June, 1853. 



Additional Note on Ichneumon Atropos, Curt. — At a meeting of the Linnean So- 

 ciety on the 15th of February, 1853, there was read " an ' Additional Note ' to Mr. 

 Newport's Memoir on Ichneumon Atropos, Curt, in reference to the changes which 

 take place in the alimentary canal after the parasite has ceased to feed, and while as- 

 suming its imago state. These changes, which are very considerable both as regards 

 form and condition, are minutely described; and every part of the canal is shown to 

 be supplied with tracheae, the trunks of which, one in each segment, passing trans- 

 versely inwards, divide into branches, which, again subdivided, penetrate into and 

 ramify through the structure. These, like all other tracheae, are formed, as described 

 by Sprengel, of three tissues, an external membranous and an internal mucous, inclos- 

 ing between them a strong spiral fibre. The nature and origin of the external tissue 

 have been shown by Mr. Newport in previous memoirs ; but he has since found that 

 the ramifications of the tracheae which penetrate the structure of the canal, or of any 

 other organ, become denuded of this external covering, and then seem to be formed 

 only of two tissues, the spiral and the mucous, if indeed there be not also, as he has 

 some reason to think, an extremely delicate serous, or basement membrane, closely 

 adherent to and uniting the coils of fibrous tissue on its external surface. The ulti- 

 mate divisions of the tracheae are always distributed separately, and do not anastomose, 

 ending, as noticed by Mr. Bowerbank, in extremely minute, filiform, blind extremi- 

 ties ; and this Mr. Newport finds to be their condition in all structures, in the nervous
