whether specimens found at the end of August constitute a 

 third generation, or are only late examples of the second. 



Lakva active, pale yellow ; head brown ; dorsal plate 

 pale yellow like the body, but with two black or brown spots 

 on the hinder edge ; anal plate imperceptible ; raised dots 

 small and obscure. (W. Warren.) 



June, July, August and September, in the seed capsules 

 ot' Liiiaria vnUjaris. (W. Warren). But Lord Walsingham 

 has more than once reared this species from seed-heads of 

 Plantarjo lanccolata, among which the moth usually flies ; on 

 the other hand Mr. E. A. Atmore confirms Mr. Warren, 

 and has reared a lot of fine specimens from Lliiaria flowers. 

 To heighten the difliculty it appears that the larva on 

 Linaria leaves the seed capsule and enters the ground to 

 pupate ; while that on Plantago lanceolata spins up and 

 becomes a pupa in the seed-head. Lord Walsingham says, 

 " In this neighbourhood the insect may be relied upon to 

 appear within three years after any piece of heath or 

 cultivated land in the light sandy soil has been broken up 

 and enclosed, whether planted with trees or left unculti- 

 vated. It continues to frequent such places for three years 

 or more, but disappears when the vegetation becomes 

 thicker, even before the Plantago has been completely 

 smothered out. It flies just before sunset, and there are 

 certainly two distinct broods, roughly speaking one in the 

 first week in June, the other the first week in August. I 

 have met with specimens which I could not separate as 

 belonging to any distinct species among patches of Linaria, 

 as well as at a distance from any Linaria, but whenever 

 I have found it among Linaria, Plantago has always been 

 present in some abundance." My own experience of the 

 insect coincides closely ; but though I have often searched 

 for the larva on Plantago it has always been without success. 

 I have, however, often seen the moth settle upon this plant, 

 always placing itself across the spikes. Its flight before
