18 [June, 



The egg is of a regular round shape, convex above, and depressed on the under- 

 surface, the shell ornamented with numerous fine ribs and reticulations ; when first 

 laid the colour is a pale bluish-white, by the fourth day changed to a light pinkish- 

 grey, with a zone round the middle and a blotch on the top of light brown, which 

 deepening day by day makes the pale ground still paler by contrast, until the ninth 

 day when the whole egg becomes uniformly of the hue of the bloom on a cluster of 

 purple grapes, and in a few hours the larva is hatched. 



The newly liatched larva has a very pale and transparent pinkish-grey body, and 

 a pale brown head, the dorsal vessel showing blackish-brown through some of the 

 segments, but after food has been taken and growth commenced the skin shows glossy 

 liglit yellowish-watery-grcen, with minute black dots. After the first moult the 

 colour changes to a more opaque bluish-green, still with the black dots, and with a 

 paler widisli dorsal and narrower sub-dorsal lines, the head of a yellower-green, 

 sprinkled with black atoms ; after the second moult the same tint of green was re- 

 tained, with the dorsal and sub-dorsal lines as before, but now a still paler spiracular 

 stripe appearo, and in this stage — when the length is about f inch long — the larva ia 

 much like the young larva of Tceniocampa goihica, except that it is more slender and 

 the pale lines are not so white nor so sharply defined. After the third moult the 

 coloui's are much as before, but now the spiracular stripe is decidedly greenish-yellow, 

 or ochreous-yellow, and the tubercular black dots are imperfectly ringed with whitish- 

 yellow. After the fourth moult the general colouring, though deep and of sober 

 richness for a 'time, gradually grows paler, and three varieties could be noticed, 

 brownish-green, ochreous-green, and one or two light brown, the markings as before ; 

 when the larva is about an inch long the last moult occurs, and the size and colouring 

 become that now to be described as belonging to the full-grown larva: the length is 

 from l-i to If inches, the figure tolerably stout, cylindrical, yet tapering very little at 

 either extremity, the eleventh and twelfth segments being rather the thickest, and all 

 the divisions very slightly defined, the skin soft and smooth ; the colour of the 

 glistening head is pale pinkish-drab, with a blackish-brown streak down the front of 

 each lolie, a finer streak at the side, and delicate reticulations on the oth^^r parts ; the 

 ground colour of the back and sides isochreous-greenish-brown, very much but finely 

 freckled with brownish -grey; the second segment is thickly freckled with dark grey- 

 brown, and edged on the front margin with very dark grey, through which, rather 

 distinctly, pass the fine thread-like dorsal and sub-dorsal lines, a trifle paler than the 

 ground ; but on the rest of the body they are of the ground colour merely relieved 

 with outlines of grey-brown, and can only just be traced in their course, more or less 

 interrupted, along a series of double dorsal diamond-shapes of close darkish grey 

 freckling within a larger diamond outline of freckles on the back of each segment ; 

 each of the small tubercular spots, which are ranged in threes on eitlier side of the 

 dorsal region, is of cream-colour or pale drab, bearing a dot of blackish-grey on its 

 upper margin ; lower on the side is a single similar tubercular spot, below which the 

 grey freckles form a dark contrasting edge to the paler widish spiracular stripe of 

 feddish-drab or flesh-colour, most delicately freckled with whitish ; the spiracles are 

 pale flesh-colour, finely outlined with black ; the side below them with the legs is of 

 similar freckled ground-colour, but rather paler than the back, and the belly is 

 iTufreckled.
