<J genitalia. Valva rather short ; costa thickened, straight ; valvuhi small, 

 pointed ; saccTilus almost straight, with small projection beyond half ; socii 

 large, partly erect. Aedoeagus cvirved, a lonq sjiine branching from near the 

 apex ; cornntus long, slender.

Type, (? and $ , Coll. Pierce. 



Tlie localities from which it has been obtained are Gloucester, 

 New Forest, Lyndhurst, Exeter, Willesden (Middlesex), Morpeth, 

 Darlington, Colchester, Thundersley, East Devon, Ayton, Hythe 

 (Kent), Kildale, Teesdale, and Hartlepool. 



It appears to be absent from the following localities, where 

 P. ferrncjana has been observed: — Surrey (Vine) ; Delamere and 

 Horsham (Manshridge) ; King's Lynn (Atinore) ; Tilgate and Oxshott 

 (Heath) ; Romford (Claxfon) ; Rannoch (Pierce). 



The insect has been found in various collections amongst series of 

 P. ferrugana. It is double -brooded, occuri'ing in July and October, 

 and probal>ly hibernates. It has been bred from sallow (Whittle) and 

 beaten from birch (Hanvood) and oak (Metcalfe). 



In dried examples it is necessary to break open the 8th sternite in 

 order to obtain a view of the aedoeagus, when the branched spine at 

 once separates it from all other British species of Peronea. Freshly 

 taken examples of the male should be set with the valvae open. 



Specimens examined, 95: Pierce Coll., 29; Metcalfe Coll., 10; 

 Harwood CoU., 5 ; Whittle Coll., 9 ; Atmore Coll., 2 ; Sheldon Coll., 

 1; Gardner (Hartlepool) Coll., 6; Lofthouse Coll., 11; Richards 

 Coll., 22. 



Var. I. — multipunctana, var. n. The whole svirface of fore-wing speckLd 

 with black dots. 



Var. II. — ? hrachiana Frr. Ground colour more or less yellow, with costal 

 hollow triangle crimson red. 



Var. III. — ? tripunctana Hb. Costal triangle broken into three dark spots. 



These varieties run parallel in P. ferrugana. In the early brood 

 the markings are nearly obsolete, the inner edge of costal triangle, a 

 a few apical reticulations and a tuft of black scales towards the base 

 alone appearing, ground colour very pale yellow.
