of the same colour as the head, bearing minute blackish dots, and an- 

 other plate of similar tint is on the anal tip ; the rest of the back is 

 either a lively green, or else a rather subdued transparent light green, 

 bearing a dark olive brownish pubescent or bristly dorsal line ; a naked 

 stripe of opaque greyish, or whitish-grey, follows at a short interval, on 

 which the minute tubercular black dots are visible ; then comes the 

 sub-dorsal thinner stripe of the transparent greenish ground colour, and 

 then another naked thin stripe of greyish, which is succeeded by a 

 broad lateral band of the ground colour, but so thickly covered by a 

 minute bristly kind of brown pubescence as to assume an olive hue, 

 and just within its lower margin are the circular brownish-red spiracles, 

 outlined with black, and surrounded with a ring of naked ground ; be- 

 neath them runs an inflated and puckered stripe of opaque greyish- 

 white, relieved below by a line of brown pubescence ; the belly and all 

 the legs are of the pale greenish ground colour, and but very slightly 

 pubescent ; on the belly, between each pair of the anterior legs, at their 

 base, are two black spots; the ventral legs tipped with brown." 



Pupa — A very complete description of the pupa is given by Mr. 

 Buckler, who writes: — "The pupa which is attached by the tail to the 

 stem, or to a leaf, is half an inch in length, slender, with a longish beak 

 in front projecting at a slight angle downwards from the head, pointed 

 at the tail ; the wing covers of moderate length, well developed, and 

 the ends of the leg-cases projecting free from the abdomen ; its figure, 

 in repose, is a little curved, so as to be concave on the back. In colour 

 it varies, some examples being very pale greenish, others light pinkish- 

 grey, while others again are dark reddish-grey ; in the pale green 

 variety the characteristic darker markings, though partially present in 

 deeper tints of greenish, are more tenderly rendered than in some of 

 the greyish varieties, which are marked as follows : the beak is white 

 above, and black at the sides ; on the thorax a blackish-brown dorsal 

 stripe widens and then narrows, and from thence passes down of uni- 

 form width to the tail ; on the thorax it is margined with a line of 

 white ; the sub-dorsal line is blackish-brown and rather interrupted ; 

 between this and the dorsal stripe, on each segment, are double dark 

 brown streaks a little divergent ; these are strongly marked on the an- 

 terior segments, but more faintly, by degrees, on the hinder ones ; at an 

 interval below the sub-dorsal, another brown line occurs, rather inter- 

 rupted ; the lateral line is white, bordered beneath by a stripe of black ; 

 the ventral surface of each segment has a broad central somewhat
