HPHYRA ORBICULARIA. 
Plate CXV, fig. 9. 
On the 29th of July, 1876, I received, through the 
kindness of Mr. J. G. Ross, of Bathampton, a dozen 
full-crown larvee of this species. 
Length about an inch, and of moderate bulk in 
proportion; the head has the lobes rounded, is slightly 
notched on the crown, and is the same width as the 
second, but narrower than the third segment. Body 
cylindrical and of nearly uniform width throughout, 
the front and last three posterior segments, however, 
being slightly narrower than the middle ones; the 
seemental divisions are well defined, and the skin has 
a somewhat tough appearance. Ground colour of the 
dorsal surface bright apple-green; head pale brown, 
very prettily reticulated and spotted with dark brown, 
and two stripes of the paler brown colour running 
through each lobe are very conspicuous; a pale greyish 
line, finely edged with dark green, forms the dorsal 
stripe ; the subdorsal lines are of the same colour, but 
waved throughout their entire length; the whole of 
the spiracular region, including the space between the 
subdorsal and ventral regions, is In some specimens 
entirely white, but in others is very delicately and 
beautifully marked at regular intervals throughout the 
entire length, with blotches of pink or bright pale 
purple. On each side of the fifth, sixth, seventh, 
eighth, and ninth segments is an oblique smoky mark, 
each mark commencing on the front of the segment, 
and extending backwards into the pale spiracular area ; 
the usual dots and spiracles are distinct, black. The 
ventral surface is green, with five longitudinal white 
Bee —a central one, and two on each side outside 
the usual dots distinct here, too, and also black ; 
a prolegs tipped with pink. 
It feeds on sallow; and when full-fed, like others 
in the genus, affixes itself to a leaf by the anal claspers,
