472 Hon. N. Charles Rothschild's Notes on 



All the larvae that I have examined were secured in 

 stems of the Wayfaring tree, Viburrium lantana, but the 

 above-mentioned record would lead one to suppose that 

 the species mines both in Viburnum lantana and in 

 V. opulus. The first larva that I found was mining in 

 a bush of V. lantana at the edge of the author's garden 

 at Ashton Wold, Oundle, Northamptonshire, in November 

 1905. This specimen duly emerged as a fine female on 

 the 12th June this year. During a walk in Surrey in the 

 winter of 1905 I was surprised to see in a hedge 

 several old mines of this species, but owing to a lack of 

 time was unfortunately prevented from re-visiting the 

 spot. At the author's request Mr. H. McArthur went 

 there in the following spring and secured two larvae in the 

 same hedge, which never emerged. The author found a 

 mined stem, this time containing a pupa or full-fed larva, 

 in another part of Surrey in 1906, which, as previously 

 recorded, emerged on the 10th June, this specimen being a 

 male. Mr. H. McArthur then visited another locality in 

 Kent, and there was successful in securing several larvae 

 and pupa?, two of which, a male and a female, emerged on 

 the 2nd and 6th July respectively. Some of these larvae 

 are still feeding at the time this article goes to press, and 

 others produced ichneumons. The author found two more 

 larvae, both of which unfortunately died, in Huntingdon- 

 shire, and numerous old mines in Kent. The description 

 of the larva, presumably about two-thirds grown, and of 

 the empty pupa-case (for which I am indebted to Mr. 

 Eustace Bankes and Dr. T. A. Chapman), are appended to 

 this article. The peculiarity of the present species is that 

 the mine is unlike that of any other Sesiid with which 

 I am acquainted, and to exhibit these peculiarities, 

 photographs on Plate XXVIII have been taken. The 

 empty mine of the insect in question is most characteristic 

 and cannot, we fancy, be mistaken for anything else, see 

 Plate XXVIII, fig. 2. It will be noticed from an examina- 

 tion of the photographs that the insect in question makes 

 one straight mine in the centre of the twig or bough. One of 

 the stems we have measures nearly two inches in diameter, 

 while another is half an inch across or less. An opening 

 from the mine to the outside of the bough (the opening 

 from which the larval frass exudes and the insect emerges) 

 is almost at right angles to the mine.
