the leaf of its food-plant, and, attaching itself to this, both by 

 its feet and claspers, it is very difficnlt to remove ; it remains 

 perfectly without motion during the day, exposed to the 

 rays of the sun, and feeds during the night : after feeding it 

 sometimes remains clasping the margin of the leaf it has 

 been eating: when at rest the head is nearly withdrawn into 

 the 2nd segment; the 1 1th, 12th and 13th segments are ele- 

 vated, and the anal horns closely approximate and pointing 

 in a straight line backwards. Head prone, narrower than 

 the 2nd segment, into which it is received ; the body rises 

 from the head to the 4lh segment, which is produced into a 

 transverse dorsal ridge ; thence the body gradually tapers to 

 the anal extremity ; the 1 1th, 12th and 13th segments form- 

 ing a cone ; the anal claspers are changed into cylindrical 

 tubes, each of which is covered with short bristles, which 

 give it a scabrous feel as well as appearance ; and each of 

 which also contains a slender filament, capable of being pro- 

 truded at the will of the larva. Colour of the head grayish 

 brown, the sides dark brown, the face delicately reticulated : 

 dorsal surface gray-brown, marbled with darker and lighter 

 shades, and bordered throughout with bright yellow ; lateral 

 and ventral surface bright apple-green, doited with purple- 

 brown, and every dot emitting a small black bristle ; on the 

 5th segment the green colour extends completely round the 

 larva, interrupting the dorsal brown area, which recommences 

 in a point, and increases in breadth to the 8lh segment, on 

 which it descends below the spiracle ; it then gradually nar- 

 rows to the 12lh segment, and again expands on the 13th ; 

 anal tubes green, with a brown patch on the inner side of 

 each near the base ; a brown annulus beyond the middle, 

 and a second paler annulus at the tip ; filaments black ; 

 spiracles brown ; ventral surface of the lOlh, 11th and 12th 

 segments blotched with brown ; legs green, each joint with 

 a red mark on the outside. When full-fed it excavates a 

 portion of the bark of the tree on which it feeds, and in this 

 constructs a very strong glutinous cocoon, so like the bark in 

 colour as to be seen with difficulty. The moth appears in 

 June following. My late beloved nephew, George Newman, 

 found a great number of these larvae at Leominster in 1865.
