it tapers also from the eleventh segment to the end of the thirteenth : the segmental 

 divisions are well defined on the back, and rather deeper on the belly ; the legs all 

 tolerably ■weU developed. 



The colour of the head is very pale, either of a broAvnish-yellow or greyish- 

 yellow, semi-pellucid and shining, the ocelli large and blackish, the mouth blackish- 

 brown ; on the second segment, is a shining plate of the same colour as the head, 

 bearing minute blackish dots, and another 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 wliich the 

 minute tubercular black dots are visible ; then comes the sub-dorsal thinner stripe 

 of the trsnsparent greenish groimd 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 suri'ounded with a ring of naked ground ; beneath them runs an 

 inflated and puckered stripe of opaque greyish- white, relieved below by a line of the 

 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 dark brown. 



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 hght 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 arc 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 uniform 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 anterior segments, 

 but more faintly, by degrees, on the hinder ones ; at an interval below the sub-dorsal, 

 another brown line occurs, rather interrupted ; the lateral line is white, bordered 

 beneath by a stripe of black ; the ventral surface of each segment has a broad central 

 somewhat squarish mark of light brownish-grey, and a fine sub-ventral Hue of similar 

 tint mucli interrupted ; the wing-covei-s brownish-grey with whitish rays.

Description of the larva, c^'c, of Pterophorus microdactyhis. — To Mr. Wm. H. 

 Grigg, of Bristol, I have been indebted for the good opportunity afforded me of 

 studying this interesting plume lai'va, by his very kindly sending me a number of 

 examples on the 26tli Jidy, 1875, which, two days before, he had found in the 

 flowering stems of Eupatorium cannabinum.
