form is widely distributed in Europe, Asia and eastward to Japan. 

 It has been recorded by Meyrick^ as common in England and cen- 

 tral Europe. Ele states that the larvae feed on oak, birch, hazel 

 etc., while Rouast^ has recorded it as feeding upon pear, cherry, and 

 oak. The larvae drew the leaves of the Japanese maple together 

 into an irregular, somewhat cornucopia-shaped mass in which they 

 transformed to the pupa. 



The adult moth has a wing spread of 34 of an inch and the gen- 

 eral plan of markings is somewhat similar to our native A r c h i p s 

 argyrospila \\^alk., though the general color is much darker. 

 The antennae, head and thorax are a rather dark fulvous brown, 

 particularly the latter. The forewings are a dark reddish brown 

 and a light yellowish brown,, with narrow, transverse purplish 

 brown markings at the extremity. There is a variable dark brown 

 stripe along the basal third of the costal margin, ending in a 

 rather broad, oblique, dark reddish brown and yellowish brown 

 stripe extending nearly across the wing to the outer angle. There 

 is a distinct semioval, dark brown mark on the distal third of the 

 anterior margin, which latter is continued as an indistinct lighter, 

 yellowish brown, tapering mark nearly to the posterior border of 

 the wing. The basal third of the wing and the portion lying be- 

 tween the oblique mark is a variable yellowish brown with inter- 

 mixed purplish brown scales. The tip of the wing, exceot that 

 part shaded by the outer oblique line, is yellowish brown with the 

 veins and a series of irregular, narrow, transverse lines mere or 

 less distinctly marked by purplish scales. Hind wings dark pur- 

 plish brown, fringe of both wings pale yellowish brown. Abdomen 

 a variable yellowish, cr 3^ellowish brown and posteriorly orna- 

 mented with long tufts of yellowish brown scales. 



This moth differs from the native species at hand by its darker 

 color in connection with the narrow, irregular, transverse lines on 

 the outer portion of the wing. 



The larva is about i inch long. Head light amber, mouth parts 

 darker ; thoracic shield light amber, lateral and posterior margins 

 dark brown or black. Body dark olivaceous, with a subdorsal row 

 of distinct whitish tubercles, dorsal vessel slightly darker ; lateral 

 ridge and ventral surface semitransparent, yellowish green. True 

 legs black, prolegs whitish transparent. The caterpillar is sparsely 

 clothed with fine, whitish hairs. Lateral and subventral tubercles 

 inconspicuous, as they are concolorous with the paler portions of 

 the larva. Some of the larvae are somewhat lighter, having lighter, 

 subdorsal stripes, and in one smaller individual the dorsum is very 

 little darker than the venter, with darker, indistinct, broken, sub-
