DESCRIPTIVE NOTICES OF CONSPICUOUS SPECIES 275 



on the inner margin, the other a little beyond it on the 

 costa. 



The larva is pale greyish -green, with the head and 

 second segment pale brown ; it mines large blotches in 

 the leaves of dogwood in June and July, and when full- 

 fed cuts out a flat bivalve case, in which it descends to 

 the ground. 



The perfect insect appears in May, and may be met 

 with flying in the sunshine round bushes of dogwood. 



The closely allied, but smaller A. Treitschkiella has 

 very similar habits, feeding on the same plant. An 

 interesting note on the difference of the pupation of the 

 two species, by Mr. Charles Healy, will be found in the 

 fourth volume of the ' Entomologist's Monthly Magazine' 



(P. 10). 



FAMILY IX. AKGYHESTHID^E. 

 AEGYEESTHIA NITIDELLA. 



This species is generally distributed, and common 

 throughout the country. 



The expansion of the wings is very nearly J inch. 

 The fore-wings are very pale ochreous-brown, with a 

 darker streak from the middle of the base ; a white 

 streak runs along the inner margin, but is interrupted 

 beyond the middle by a curved dark brown fascia, which 

 terminates in the tip of the wing. 



The fat yellowish- grey larva has the head brown 

 and the second segment brownish above ; it feeds in 

 the young shoots of hawthorn in April and the beginning 

 of May ; the full-fed larvae may be seen descending 

 from a hawthorn hedge by the silken threads during 

 the first and second weeks of May.
