towards the roots of the herbage, and there pass the winter, 

 reappearing in April, when they grow much more rapidly 

 than in the autumn, and are full-fed towards the end of May. 

 Head subglobose, not much notched on the crown, highly 

 glabrous, decidedly narrower than the 2nd segment, into 

 which it is partially received : body very obese, the divisions 

 of the segments deeply incised ; the 2nd segment has a semi- 

 circular,but not glabrous, dorsal plate, its anterior margin being 

 truncate, its posterior margin convex and toothed ; it is lon- 

 gitudinally divided by a pale median line ; on each side of 

 this segment there is also a depressed scabrous wart ; the 3rd 

 and 4th segments have each four scabrous warts, arranged in 

 a transverse series; the 5th, 6th, 11th and 12lh segments 

 have sixteen warts each, two of them small, dorsal and ap- 

 proximate near the anterior margin of the segment, two still 

 smaller and more approximate on the belly, and the remain- 

 der forming a transverse series of six on each side ; the ven- 

 tral warts are absent from the 7th, 8th, 9th and 10th seg- 

 ments, and on each of these a ventral clasper occupies the 

 place of the lowest wart of the transverse series ; every wart 

 emits a fascicle of radiating bristles. Colour of the head 

 pitchy red, the cheeks tessellated with paler : the body is 

 smoke-coloured, with a medio-dorsal paler, almost yellowish, 

 but rather inconspicuous stripe, interrupted at the incisions 

 of the segments ; there is also a transversely elongate spot of 

 the same colour between the 4th and 5lh warts, on each side 

 of each segment ; legs black and glabrous ; claspers smoke- 

 coloured, like the body, but slightly glabrous ; bristles 

 mostly pale brown, a few of them black. When full-fed the 

 larva spins a somewhat boat-shaped cocoon of rather closely 

 woven silk, interspersed with its own hairs, on the under side 

 of a leaf or on some leaf-stalk, or on a blade of grass, and in 

 this cocoon it turns to an obese black pupa, with a pale pos- 

 terior margin to each abdominal segment ; the thorax is dor- 

 sally very convex, the segments strongly marked, and the 

 anal segment converted into an incurved horn. The moth 

 appears on the wing in June. I am indebted to Mr. Greening, 

 of Warrington, for a liberal supply of the larva of this insect.
