DESCRIPTIVE NOTICES OF CONSPICUOUS SPECIES 255 



the base a broad white streak runs along the fold nearly 

 to the middle ; thus the basal portion of the wing is 

 prettily varied with white, but the blackish colour forms 

 a broad, rather oblique uninterrupted band beyond the 

 middle ; beyond this the apical third of the wing is 

 white, sparingly clouded with pale grey. 



The perfect insect appears in June and July, and may 

 be found in the daytime resting on the trunks of trees. 



FAMILY I. TORTRICID.E. 

 SID ERE A ACHATANA. 



(Plate XIV., Fig. 2.) 



This species seems widely distributed in the south 

 of England, and in some localities it is far from un- 

 common. 



The expansion of the wings is about J inch. The 

 fore-wings are pale grey, with a large dark brown patch 

 at the base ; on the middle of the costa is a small 

 quadrate dark brown spot, and on the inner margin 

 beyond the middle is a larger triangular spot of the 

 same colour ; on the costa at the tip is a rather trian- 

 gular reddish-brown spot. 



The perfect insect appears in June and July, and 

 frequents hawthorn hedges, from which it may often be 

 obtained by beating during the daytime, or flying of its 

 own accord towards dusk. 



FAMILY I. TORTRICIMJ. 

 TORTEIX VIRIDANA. THE GREEN TORTR1X. 



This pretty species is common, sometimes in extreme 

 profusion, and generally distributed throughout the 

 eoimtry.
