88 ^September, 



diamond pattern of sitnk lines, eacli diamond having a central sunken dot ;* the eolour 

 at first pale, afterwards rich deep yellow, with the edges still deeper, and a red tinge 

 near the bigger end ; at last becoming again quite pale, but with a dark spot. 



The young larva escapes by eating out one end of the egg ; in colour it is whitish, 

 with a purplish tinge in the front segments from the internal organs showing through ; 

 as it grows it becomes quite shining white ; after the first moult it is glassy looking 

 and translucent, with an internal green stripe through the body, probably caused by 

 the presence of food ; when about three-eighlhs of an inch long it is uioi'o opaque, 

 with the back whitish-green, a broad dark green sub-dorsal stripe, the head greenish- 

 white, all the rest pale green ; the bristles conspicuous. 



Soon after attaining the length of three-eighths of an inch, it passes its last 

 moult, and, after that, grows rapidly ; the markings are at first paler in the lighter 

 portions, and darker in the dark portions, than they become afterwards. 



The fuU-fed larva is about three-quarters of an inch long, slender, but cylindrical 

 and plump, of almost uniform size throughout, except that the head is narrower tlian 

 the second segment, and the last three segments taper off both in width and in 

 thickness ; the skin soft and rather glossy, wrinkled at the divisions, puckered along 

 the sides, and set with a few hairs. 



The general colour on the back and sides is pale greenish-yellow, the belly slightly 

 greener ; the crown of each lobe of the head is marked with a streak of crimson- 

 brown ; tlie collar is shining ; on segments 2—4 is a long oval dorsal patch of pinkish 

 or crimson-brown, widest on 3, and ending in a blunt point at the division between 

 4 and 5 ; through this runs a central thread of yellow, bordered with au edging 

 of brown, darker than the patch, which has also a darker line running along just 

 inside its outer cuiTed edged ; about the middle of 6, commences a pair of lateral 

 blotches, which run through 7 and 8, of either rose-pink or crimson-brown, having a 

 streak of darker brown just in the place of the sub-dorsal line ; these blotches have 

 waved edges, which nearly meet at the segmental divisions both above and below ; 

 through 5 — 11 inclusive, there is no dorsal line whatever, but on 12 and beginning 

 of 13, in the place of the dorsal line, is a broad stripe of rose-pmk, bearing at each 

 end a dark spot of crimson-brown : the spiracles roundish, but very hard to bo seen, 

 being greenish-yellow on the ground colour, and brown on the coloured blotches ; 

 so too with the usual warts, on tlie ground they are scarcely to be seen, but on the 

 blotches they become prominent, shining, and dark brown. 



The above description applies to all the larva; I have reared this season, for there 

 is scarcely any variation amongst them, but among the captured larva; last year there 

 was a great deal; this was shown not only in the depth of colour of the blotdies, 

 but also in their size, and by their abseuce ; one variety was greenish-yellow all over 

 with no niiu-kings whatever; another had the blotcli on 2,3, and 1, and a dot on 12, 

 and nothing else; another liad a dark dori^al spot in the middle of 5 ; another had 

 a similar spot on G, almost coinieeting the lateral blotches ; the example had a dark 

 spot on the side of the anal logs. 



The larva, last year, retired into the earth furnished thom for pujiation, ami 

 there made weak, rouiulish, oval cocoons, nearly half an inch long, and formed of 

 peaty fibres and eartli, spun together with a slight lining of silk.
