transverse lines strongly marked, in which also are three 

 black longitudinal stripes running along nervures, one from 

 the claviform stigma and two from the reniform, all of them 

 very conspicuous and attaining the second transverse line ; 

 another in the same collection has two large parallel black 

 elongated blotches in the fore wings, totally concealing the 

 stigmata. Mr. Eustace Bankes has a wonderful specimen, 

 taken at South Norwood, London, of a uniform brownish- 

 white, without trace of either transverse lines or stigmata, 

 and with scarcely a trace even of the black bar across the 

 front of the collar. Its resemblance to a Leucania is so great 

 that it was originally supposed to belong to that genus, and 

 was only recognised by the form of its thorax and fore wings. 

 A specimen in the cabinet of the late Mr. F. Bond has its 

 right fore wing extended laterally to double the normal 

 width, the markings thereby rendered smeared and indis- 

 tinct. Mr. S. Stevens has a very large and broad-winged 

 female specimen which has an elongated blunt blackish 

 blotch on each side of the median nervure, and the subter- 

 minal line shifted out of its usual position. Mr. 0. W. Watts 

 possesses a specimen taken by himself in the north of 

 Ireland, in which the basal portion and the whole space 

 beyond the second line are dark brown, while the central 

 area is of the usual pale brown. 



Variation in the hind wings is very slight, but an occa- 

 sional male has a grey-brown band along the hind margin. 



On the wing in June and July. There is a record of a 

 casual emergence in October. 



Larva moderately stout ; ground colour a rather warm 

 brown varying in intensity a little in individuals ; very 

 constant in colour and design. Down the middle of the back 

 on each segment . is a pear-shaped blotch of darker brown, 

 composed of freckles, the broad end of the pear in front ; 

 through these the dorsal line can scarcely be traced beyond 

 the fourth segment, though it begins on the second, by
