(Arranged according to L. B. Prout's classification in Seitz's 

 ' Palaearctic Macrolepidoptera.') 



Abraxas grossulariata. — A very varied series of 135. 



Most of the specimens are wild ones, with the variation 

 tending to an increase of the black coloration, but two specimens 

 from the Meldola Collection, taken in Wigtonshire, are almost 

 quite white. Among the bred specimens are 3 var. nigro- 

 sparsata, 6 var. lacticolor, and 9 var. varleyata. 



Angeroma prunaria. — A remarkable specimen of the ab. 

 corylaria type from the Meldola Collection labelled " Essex. 

 Chingford," has the usually dark base and outer margins of a 

 pale ochreous colour with a reddish orange central band. 



Gonodontis bidentata. — In the long series are 13 ab. nigra, 

 Prout, from Yorkshire, and 14 from the Manchester district. 



Ourapteryx sambucaria. — A specimen from the Chitty Col- 

 lection, labelled "E. Woodhay, 1882," is almost pure white. A 

 specimen of a second brood was presented by Mr. J. Collins, 

 taken by him October 3rd, 1921. 



Opisthograptis luteolata. — A specimen from the Meldola Col- 

 lection, bred from a Perthshire larva, May 5th, 1912, has both 

 hind wings and the lower half of the left fore wing pure white. 



Venilia macularia. — A specimen from the Meldola Collection 

 labelled " Kent, Dartford, June 25, 1872," is almost pure yellow, 

 a few of the normal dark markings being very faintly shown by 

 a pale ochreous colouring. 



Macaria liturata. — The series includes 6 specimens of ab. 

 nigrofulvata, Collins, 2 from North Staffs, and 4 from Delamere, 



Phigalia pedaria. — The series includes many specimens of ab. 

 extinctaria and ab. monacharia. 



Nyssia zonaria. — A long series from Cheshire and Lanes, 

 and 4 from Tiree. 



Pcecilopsis lapponaria. — A long series of both 3 and 2 • 



Biston betidaria. — The long series includes several forms 

 intermediate between the type and ab. doubledayaria. 



Boarmia repandata. — Series of over 200. 



Ab. conversaria, ab. nigricata and ab. sodorensium are well 

 represented. The restriction of the melanic forms to the North 

 Midland and Northern English Counties is well illustrated. 



Cleora arenaria (viduaria). — Series of 7 from the Spilsbury 

 Collection, and 1 from the Sellon Collection.
