examples in which the second covering was constructed in two distinct sections, 

 overlapping but unconnected around the centre. Within the innermost cocoon the 

 larva spins no means of attachment, but, on the contrary, has certain powers of 

 muscular locomotion. The imago effects its escape through a subcircular hole a 

 little on one side of the apex ; if, however, through lack of oral fluid, &c., it is 

 unable to emerge, it turns round in the cocoon, protrudes its white tarsi from the 

 incomplete orifice, and invariably dies in this position. 



Besides Mamestra hrassicce and Hadena oleracea, it has been bred 

 from Betinin pinicolava (Trans. S. Lond. Soc., 1890), and Miana 

 furuncula (Entorn., 1881, p. 141). It is very widely distributed, 

 having been recorded from Land's End, York, Earlham near Norwich, 

 Essex ; and I have seen examples from Barnstaple, Lidford, Notting- 

 ham, Carlisle, Aberlady, Birmingham. Plumstead, St. Ervan in Corn- 

 wall, Worksop, linnton, Derbyshire, Woodbridge, Bristol, as well as 

 from Guernsey and Alderney. It is very common in gardens at 

 Galashiels and Ipswich, feeding freely upon Heracleum and Angelica 

 flowers. It is undoubtedly the "^. alhidit arsis'' of Dallas (Elements 

 of Entom., p. 236), said to be abundant. On the Continent I And it 

 recorded from Bavaria, Russia, Brunswick, Austria, as somewhat rare 

 in Sweden extending to Lapland, from several localities in Prussia; 

 and I have seen an example captured by the Eev. T. A. Marshall at 

 Nantua in Ain.

ACR0BA8IS VERRUCELLA, Hb., and RUBROTIBIELLA, F. R., 

 AS BRITISH INSECTS. 



BY C. G. BARRETT, F. E. S. 



In the course of study of our British species of Phycitidcd I am 

 forced to the conclusion that we possess a species which has long been 

 overlooked, though described and named a century ago by Hiibner. 

 The non-recognition of this species may perhaps have something to 

 do with the state of confusion in this group complained of eighteen 

 years ago by the late M. E. L. Ragonot, in this Magazine (Ent. Mo. 

 Mag., vol. xxii, p. 27). 



In or about the year 1858 our collongut-, Mr. R. McLachlan, 

 discovered at Forest Hill, near London, then far less under the incubus 

 of the builder than is now the case, and situated on the border of 

 Surrey and Kent, a pretty species of Acrobasis, about M^hich there has 

 from time to time been some discussion, and which was placed, though 

 I think erroneously, under the name rubrotibiella, P. R.
