358 LEPIDOPTERA. 



Head dark brown, shining, without visible mouth organs, 

 but provided with drooping antennae, of moderate length, 

 curved close to the head, simple in structure, dark brown, 

 but each joint pellucid. Legs complete, dark brown, with 

 the feet light brown, and curved slightly inward so as to 

 be fitted for clinging to the case ; apparently never used 

 for walking, as the creature appears never to raise or 

 straighten itsslf. Second segment covered by a broad, 

 dark-brown, shining, horny shield, undivided and extending 

 down each side to the legs; third segment with a similar 

 narrower shield ; each following segment with a broad 

 rectangular blotch on the back ; remainder of the body pale- 

 pinkish ; anal tuft light brown ; anal segment with a tele- 

 scopic ovipositor, which in life is not usually exserted to a 

 great length except when depositing eggs m the bottom of 

 its case ; but at death is protruded as long as the whole body. 

 June. 



Larva. Head rather large and prominent, dark brown 

 or blackish, with faint yellowish lines ; following three 

 segments yellowish, each with a transverse blackish plate 

 extending down to the legs, which are long and strongly 

 made, blackish ; body deep purple-brown. In a rather thinly 

 constructed case of silk covered with slender bits of dry 

 grass placed longitudinally, but not strictly parallel, since 

 some rather diverge and give it a loose look. On palings, 

 trunks of trees, stems of bushes, rocks and even walls, 

 feeding on the minute powdery lichen which grows on damp 

 wood ; probably also eating leaves, and certainly allowing 

 itself to be tempted by any dead insect which it may meet 

 with. July to May, hybernating when almost full-grown. 



Pupa light brown, in a cocoon in the larva-case. That of 

 the male has distinct covers to the wings and legs, the 

 whole of which are broken off in one piece on emergence, at 

 which time the pupa is forced more than half way out of the 

 case. That of the female is like that of a Dipteron, except
