The following description, made from a very long series of speci- 

 mens bred by Mr. W. H. B. Fletcher from wild apple leaves collected 

 in Hants and Sussex, will probably be useful, since hlancardella does 

 not appear to have been described in detail in any readily-accessible 

 work. 



Antenncp externally pale brownish-grey, narrowly and indistinctly pale-ringed 

 at the joints, internally white. Palpi white, externally with a dark fuscous streak 

 towards apex. Face white, slightly and partially golden tinged. Head ; tuft on 

 crown golden-orange mixed with white. Thorax and tegulcB golden-orange, much 

 marked with white. Fore-wings shining, reddish golden-orange in both sexes with 

 a straight shining white basal streak, which is black-margined throughout above and 

 often also below its apex, and ends before the middle of the wing, showing no ten- 

 dency to unite with the first dorsal white tooth : the streak varies considerably in 

 width, being sometimes rather broad, and sometimes decidedly narrow. The four 

 costal and three dorsal white teeth are broad, conspicuous, and strongly lustrous ; 

 they are narrowly but distinctly black-margined internally, and the first costal 

 and first two dorsal ones are also partially black-margined externally. There is a 

 distinct black apical streak, and sometimes some black scales lie round the apices of 

 the costal and dorsal white teeth. Dorsal margin generally with a white line or 

 spot between the base and first white tooth. Cilia very pale greyish-orange beyond 

 a conspicuous black dividing line running from the fourth costal tooth round to the 

 tornus, reddish-orange anteriorly. Exp. al.,8 — 9.25 mm. Ilind-wings satiny-grey, 

 with pale grey cilia. Abdomen, above dark brown-grey, with pale grey anal tuft, in 

 the $ , brownish-grey, with pale greyish-ochreous anal tuft, in the ? ; beneath 

 very much paler. Posterior tarsi whitish, sometimes with, sometimes without, dark 

 spots above.
