seventh to the head, which is the smallest, and backward a little from 

 the tenth to the end of the thirteenth. The general ground colour is 

 [green varying in richness in different individuals, and is yellower and 

 brighter for the first few days ; the head is very glossy, greenish- 

 yellow faintly tinged with pinkish, and having two rows of pink 

 freckles down the front of each lobe, the ocelli large and black ; the 

 ; green of the body is well contrasted with the design on the back 

 which occupies the space there between the trapezoidal warts, and is 

 attenuated a little on the posterior and thoracic segments, beginning 

 on the second as merely twin lines, but on all the others consisting of 

 three equally stoutish lines of very dark crimson, of these the dorsal 

 line in the centre is straight, but each outer one in its course along 

 each segment bends inward a little towards the middle in symmetrical 

 progression, enclosing a ground of deep rose-pink within them at 

 either end, but which is lost in the middle of the segment by the 

 complete fusion there of the three dark crimson lines together in a 

 mass, just where the middle of the bends bring them near each other ; 

 after an interval of green comes the sub-dorsal line of very deep pink, 

 and at a less interval a thicker and rather sinuous lateral line, and at 

 a wider interval again below a sub-spiracular line of the same deep 

 pink colour ; the tubercular warts are whitish with minute black 

 central dot bearing a fine short bristle, the anterior pairs of the 

 trapezoidals are quite close to the crimson outer curves of the dorsal 

 design ; one wart occurs upon the anterior thickest part of the lateral 

 sinuous line, another behind each spiracle, and others again beneath : 

 the roundish spiracles are blackish with pale centres ; the yellow- 

 green of the back is more yellow close to the crimson design, and also 

 on the tumid spiracular region, which on the posterior segment and 

 edge of anal flap is primrose-yellow ; against this the outer crimson 

 surface of the anal legs contrasts strongly ; beneath on the green 

 belly are three paler lines, the central one the more noticeable : as 

 the larva matures the crimson markings of the back become purplish, 

 and the general ground a deeper green, though the spiracular ridge 

 remains yellowish to the last. 



The foregoing describes what I believe to be the typical or com- 

 plete design of the larva, for it was the one shown by all the larvae in 

 1880, and by most in 1881, but amongst the latter there occurred 

 three or four of a variety showing an incomplete form of the dorsal 

 design, which may be regarded as substantiating in a manner the 

 description in the Manual after Freyer. 



In this variety the dorsal line as usual is complete throughout,
