Occurrence of Trochilium scoliceformis in Wales. — Mr. Ash worth, already favour- 

 ably known to entomologists as the discoverer of a new Noctua, Agrotis Ashwoithii of 

 Doubleday (Zool. 4749), is the fortunate captor of a large and beautiful Trochilium 

 altogether new to this country. This insect is the Sphinx scoliaeformis of Borkhausen, 

 subsequently described as Sesia scoliaeformis by Laspeyres, who records its having 

 been taken at Darmstadt in May on the blossoms of Rbamnus Frangula: both these 

 authors, however, appear to have only been acquainted with the female, whereas 

 Mr. Ashworth has taken both sexes : this is probably the species of which Mr. Ash- 

 worth previously recorded the capture (Zool. 4814), under the name of Trochilium 

 Sphegiforme. I append a description, which may serve as an Addendum to my 

 1 Monographia iEgeriarum Angliae,' published in the first volume of the ' Entomological 

 Magazine.'

 scales; and its apex with a tuft, which is bright ferruginous both above and below: 

 wings hyaline, the anterior pair with the veins, a median costal spot, and the broad
