wings white ; near the base are three or four black dots placed transversely, and a 

 little beyond is a black transverse line, interrupted in the middle; these form, as it 

 were the margins of an extinct fascia : a little before the middle is an angulated pale 

 tawny fascia, sometimes interrupted, but oftener entire ; beyond this is another more 

 angulated pale tawny fascia ; both these are margined on both sides with black ; be- 

 yond the third, and connected with it, forming by their union the letter K, is a straight 

 tawny fascia, faintly margined with a darker colour ; from the middle of this to the 

 apex of the wing is a black line, between which and the costa are two small patches 

 of pale tawny, and on the inner margin the whole remaining space is pale tawny : cilia 

 pale. Posterior wings clear gray, with paler cilia. 



A maple feeder, and probably common wherever that plant grows. I took it in 

 great plenty, last May and June, off hedges close to my house, and again sparingly in 

 August. It has been taken by others in the Green Man Lane. 



Zeller mentions two varieties, viz. — 



Var. b. " The second fascia with a projection towards the first." 

 Var. c. " With the fascise connected by a yellowish longitudinal line." This 

 last is his acernella. 



Zeller says of its localities, " This species was found in Bohemia, near Nixdorf, 

 by Fischer-v-R., and near Reichstadt by Mann ; at the latter place it was very scarce 

 in May. Latterly Mann took it at the same time also near Vienna. I took it myself 

 near Glogau, July 8th, 1835, among a cluster of maple bushes, — above a dozen spe- 

 cimens of this species, varieties a and b, in company with Tort. Forskaleana. Mann 

 informed me that it occurs in Hanover, in September. Fischer-v-R. discovered the 

 caterpillar, from which he often bred the perfect insect ; it lives as a miner, in May 

 and June, in a maple leaf, of which, according to Mann, it turns in a corner. He 

 found it in May and June, and bred the perfect insect in June and July."

Expansion of the wings 3^ lines. Head white, with some fulvous hairs. Fore- 

 head white. Palpi white. Antenna? white, annulated with fuscous. Thorax white, 

 with a few grayish atoms. Abdomen fuscous, with the extremity paler. Legs 

 whitish. Tarsi white, spotted with brown. Anterior wings white, irrorated with fus- 

 cous, with four costal spots and three inner marginal spots, all fuscous : the first 

 costal spot arises before the middle of the wing, and is continued in a slanting direc- 

 tion half across the wing ; the second costal spot is placed a little beyond the middle 

 of the wing, and is continued more than half across the wing, its extremity being an- 

 gulated (resembling an angulated fascia with the lower part cut away) ; the third 

 costal spot resembles half an angulated fascia, and is margined externally with black ; 

 the fourth costal spot is very small, and lies just above the inner extremity of the api- 

 cal black streak : the first inner marginal spot is very near the base, and is very short ; 

 the second is nearly opposite the first costal spot, which it sometimes meets, thus form-
