TORTRICES IN THE VICINITY OF THE CHESHAM LINE. 93 



Dictyopteryx bergmanniana, Linn. (Croesia bergmanniana , 

 Wilk. ; Staint. Tortrix bergmanniana, Mey.). — Common among 

 roses, both wild and cultivated. To obtain really fine specimens 

 it is better to rear this species from larvae, which are easily 

 obtained. 



Dictyopteryx forskaleana, Linn. (Croesia forskaleana, Wilk.; 

 Staint. Tortrix forskaleana, Mey.). — Most maple bushes produce 

 this species. 



Ptycholoma lecheana, Linn. ; Wilk. ; Staint. (Caccecia 

 lecheana, Mey.). — Generally distributed. Sometimes flies rather 

 high, in the early evening. 



Ditula semifasciana, Haw. {Brachytamia semifasciana, Wilk. ; 

 Staint. Eucosma semifasciana, Mey.). — I took one example at 

 Northwood in July ; it was flying over a sallow bush which I 

 was examining by lamplight. 



Penthina corticana, Hubn. (Antithesia corticana, Wilk. ; 

 Staint. Eucosma corticana, Mey.). — Occurs at Northwood among 

 birches. 



Penthina betuletana, Haw. (Antithesia betuletana, Wilk. ; 

 Staint. Eucosma betuletana, Mey.). — Not uncommon among 

 birches at Northwood. 



Penthina capr^eana, Hubn. (Antithesia caprceana, Wilk. ; 

 Sfcaint. Eucosma caprcana, Mey.). — Two specimens bred from 

 sallow shoots obtained at Northwood. 



Penthina sororculana, Zett. (Antithesia pralongana, Guen. ; 

 Wilk.; Staint. Eucosma sororculana, Mey.). — I have a note 

 referring to the capture of this species at Northwood, but I 

 cannot find the specimen. 



Penthina pruniana, Hubn. (Antithesia pruniana, Wilk. ; 

 Staint. Eucosma pruniana, Mey.). — Common in hedgerows and 

 also in gardens throughout the whole area. 



Penthina ochroleucana, Hiibn. (Antithesia ochroleucana, 

 Wilk.; Staint. Eucosma ochroleucana, Mey.). — Occurs in most 

 lanes, but most frequently met with at Mill Hill and Chalfont. 



Penthina variegana, Hiibn. (Antithesia cynosbatella, Wilk. ; 

 Staint. Eucosma variegana, Mey.). — Common everywhere. 



Penthina sellana, Hiibn. (Antithesia sellana, Wilk. ; Staint. 

 Eucosma sellana, Mey.). — I think this species occurs on the 

 Midland Railway bank at Mill Hill. 



Antithesia salicella, Linn. (Penthina salicella, Wilk. ; Staint. 

 Eucosma salicella, Mey.). — Occurs on willows and fences near 

 Neasden. 



Hedya ocellana, Fabr. ; Wilk.; Staint. (Tmetocera ocellana, 

 Mey.). — Generally distributed. I have taken a form closely ap- 

 proaching var. hippophiiana in St. John's Wood.
