subdivisions lined in red, and their dorsal and sub- 

 dorsal spines red ; then comes on segments 7 to 11 a 

 broad dorsal band of white, with a dusky blackish 

 dorsal line, and some short black streaks ; here the 

 dorsal and subdorsal spines are white ; on 12 this 

 white band ends in a wedge shape ; 13 is black but its 

 spines are white ; the lateral row of spines all red, the 

 subspiracular row pink ; the spiracular region is marked 

 with an upper and lower waved red line, with a red 

 slanting streak behind each spiracle connecting the 

 two ; the spiracles are conspicuous, being black ringed 

 with white ; belly blackish with some red-browu marks, 

 legs blackish. The larvse suspended themselves for 

 pupation from the under side of a hop leaf ; the pupa, 

 suspended by the tail, is 20 mm. in length, and very 

 contorted in figure ; the head is rather flat, and has 

 two straight horns, 1 mm. long, pronged at their tips ; 

 the back of the thorax rises up sharply to a thin squared 

 central projection, and then falls in again abruptly ; 

 the waist hollowed ; the abdomen rising in a bold 

 curve to the tail, with its centre line marked more by 

 colour than prominence ; there is a subdorsal row of 

 nine small knobs, of which the two below the waist are 

 the highest ; the wing-cases are prominent, their 

 shoulders angulated with two flattened projections, and 

 their lower ends humped, and standing up from the 

 abdomen ; the belly contour is straight from the head 

 to the end of the wing-cases, where it falls in, and the 

 abdomen follows the curve of the back to the anal 

 spike ; this is long, stem-like, and a good deal curved 

 under, the tip thickly set with curled spines. The 

 colouring reminds one of the wings of Plusia gamma 

 and iota, being purple brown with a pink tinge ; there 

 is a pinkish-grey line down the middle of the back of 

 the abdomen, and on six of its segments slanting marks 

 forming v's with their points towards the tail ; in the 

 waist three pairs of silver spots, the first with a dark 

 dot in the silver; the other subdorsal knobs tipped 

 with reddish ; along the spiracles a rich brown stripe,
