THE GENERA OF BRITISH MOTHS, SL 
but widely distributed, having been recently taken at Brighton, Bristol, Stowe Wood, Oxfordshire ; and many 
other places. 
B. Lavicaria (the Engrailed, No. 11) is the largest and handsomest of the genus. It is found in woods in 
March and April, The larva, which still remains undescribed, is known to feed on Larch. This fine species may 
be considered rare, but has been taken recently at Brighton, Bristol, Lyndhurst, Manchester, Worcester, and 
doubtless in other localities. The Caterpillar represented at No, 12 is that assigned by Hiibner to an allied insect 
bearing one of the specific synonyms of B. Laricaria, but probably belonging to another species. 
The other species are the following: 2B. Consonaria (the Square Spot) resembles in gencral character 
B. Extersaria, vut has the engrailed bands broader, darker, and more suffused, and the white mark squarer 
inform. It was formerly considered very rare, but has been taken in great abundance recently at Halton, in 
Buckinghamshire, and in some plenty in several other localities. B. Crepuscularia (the Small Engrailed) closely 
resembles B. Laricaria, but is paler, and the markings aro often less sharply defined; it is also rather 
smaller. B. Punetularia (the Gray Birch) is much smaller than cither of the preceding ; and is of a dull gray, the 
markings being indistinet, and powdered with blackish specks. It is very common in woods in May. Bristol and 
Manchester are recorded as places where it has recently been taken in great‘abundance ; and it is, in fact, plentiful 
in all favourable localities.
