2154 Insects. 



extremity paler. Legs white. Tarsi white, spotted with fuscous. Anterior wings 

 white ; near the base is a pale golden fascia, nearly straight ; in the middle is a second 

 pale gold fascia, angulated and generally interrupted ; the extremity of the costal half 

 of it is sometimes continued towards the apex of the wing till it meets the next fascia ; 

 the third fascia is more angulated than the second, and most frequently interrupted ; 

 all the fascia? are margined on both sides with brown ; the extremity of the costal half 

 of the third fascia is continued to the apex of the wing, and in it, close to the apex, 

 is a darker patch ; between this and the costa are two short, pale golden streaks, edged 

 externally with brown : cilia whitish, with a black arch round the apex of the wing, 

 and some black marks at the extreme apex, somewhat resembling a hook. Posterior 

 wings whitish gray, with paler cilia. 



This very much resembles the following ; but the colour of the fascia? is much 

 more delicate, and the first fascia, which is only margined in sylvella, is filled up in 

 this insect : perhaps the easiest character by which to recognize this species at once is 

 the anal angle of the anterior wings being pure white, whereas in sylvella the first 

 costal spot is continued across the wing, forming, as it were, a fourth fascia. 



Apparently a scarce species in this country. Mr. Ingall has two, one of them be- 

 ing Haworth's original specimen ; Mr. Bedell has two and Mr. Douglas one. Nothing 

 is known of their locality. 



Zeller says of it, " At Berlin and Glogau, very scarce, in May, in company with 

 roboris, quercifoliella, Cramerella, &c. At Vienna it is more plentiful, and Mann 

 took it in April and May : according to his observation the caterpillar mines in oak 

 leaves. Duponchel found the insect near Paris, on elms, at the end of June, conse- 

 quently the second brood." 



Fabricius says of this insect, " With three yellow fasciae, the third interrupted. 

 Habitat, Paris" Zeller complains of the brevity of the Fabrician description, and 

 says that there is the probability of some species still more closely allied occurring with 

 Fabricius. If it did occur, it has ceased to occur : moreover this insect is found near 

 Paris, according to Duponchel, the very locality assigned by Fabricius. That Ha- 

 worth intended this species is proved, independently of his original specimen, by his 

 saying, at the end of his description of sylvella, " perhaps a variety of the preceding." 

 This appears to have escaped the notice of Mr. Stephens, who had specimens of Cra- 

 merella in his cabinet as hortella, which is perhaps also the cause of the imperfect 

 description in the ' Illustrations,' which has excited Zeller's indignation — " What in- 

 deed does Stephens merit for this, that he at the present day should serve up such a 

 description ! "
