82 GLUPHTSIA CRENATA. 



of a bar across between the primrose-yellow subdorsal 

 stripes, but divided by a very fine dorsal line of the 

 light green ground colour, which is of a very tender 

 and delicate tint ; the head was rather paler and 

 whiter, semi-transparent greenish ; the belly and 

 ventral prolegs similar ; the spiracles were of a faint 

 reddish flesh colour. 



In form it was cylindrical, of about equal substance 

 throughout. By the 21st it had grown to one inch 

 two lines, the ground colour a stronger but still a light 

 green, the subdorsal lines bright primrose-yellow, the 

 rust-red marks were very deep and bright, most finely 

 divided dorsally by a hair-like line of the green ground 

 colour ; it ate large pieces out of the leaves, clinging 

 tightly to them and the more so when in the least 

 disturbed ; hence, it would probably not be easily 

 beaten from the tree unless the leaf should be 

 knocked off. 



On the 22nd of September the most forward showed 

 in the intervals between the red marks (and on the 

 intermediate segments also) a dorsal stripe of whitish- 

 green paler than the ground of the back. During the 

 last two moults the entire colouring had been opaque 

 though bright, the lower part and the legs of a whitish- 

 green tint ; above the anterior legs along the thoracic 

 segments was a thin, inflated stripe of primrose-yellow. 



When looked at on the 23rd it appeared thicker on 

 the middle segments of the body and tapering at either 

 end, though viewed from above this was less percep- 

 tible. The larva which had last moulted died on the 

 23rd, a fate expected by its feeding but little after its 

 final moult. The surviving larva now measured one 

 inch two and a half lines ; it spun up between two 

 leaves of poplar on the 25th. The moth appeared 

 June 19th, 1883. 



The silken cocoon was then found to be of an irreg- 

 ular, rather ovate form, of semi-transparent drab colour, 

 one inch long, eight lines in diameter, of a light and 

 moderately open-worked texture, but the real strength
