segment being tlic smallest and very short ; the head swells out again beyond tlio 

 size of the second segment, but not to such an extent as in some others of the genus. 

 But, in justice to the talented author, I will here quote from Professor Zeller, whose 

 admirable observations and account of this larva from the egg to full growth were 

 published in 1862 in ' The Weekly Entomologist,' vide Vol. i, pp. 10 — 12. 



" * * * Wlien full grown they seek for a retired shelter, which they 

 " find in a corner, or between some leaves, of which they form a spacious habitation 

 " by spinning in the open parts a thin wall of whitish silk web, with large and very 

 " irregular meshes ; the resting place being thickly covered with whitish silk, but 

 " most thickly where the tail of the larva is to rest. In four or five days it changes 

 " into the pupa. 



" This larva is of the general form of PampJiilus, i. e., cylindrical, tapering 

 " towards the tad and head, the latter being large and as it were separated from 

 " the trunk by a string. It is of a pale greyish-green, with the dorsal vessel darker 

 " and edged with a slender pale yellow hue on either side, and enclosing a pale 

 " longitudinal line along its middle. A narrow yellowish Hue runs above on the 

 " side, and a broader one below. The two dorsal lines are prolonged as far as the 

 " middle of the head, and run to the end of the flat anal shield, which is narrowly 

 " edged with pale yellow. The transverse folds of the skin are yellowish. The head 

 " is rounded with inflated cheeks, the brownish mouth sunk deep between them. 

 " The colom* of the head is brown in the young larva, paler in the older ones, with 

 " the two yellowish lines very distinct and exteriorly edged with bro\^^l, — gi-eenish 

 " in the oldest ones, with lines shorter and paler, w;ithout darker edges. The legs 

 " are very short and greenish, the ventral ones having usually a longitudinal yellowish 

 " stripe. The two snow-white patches on the under-side of the tenth and eleventh 

 " segments are conspicuous as in P. lineola, si/lvanus, and comma, and appear to 

 " be a peculiarity of the whole genus. This wliite substance is spread out at the 

 " tail-end of the larva of P. Actceon, when it has formed its chi-ysahs case." 



As regards my four larvae, but little can be added to the foregoing, — merely that 

 the spiracles were pale flesh colour, situated on a fine and faint pale line, which 

 touched them in front and vanished behind each spiracle ; that the lower pale stripe 

 was inflated and rather overlapped the venti-al legs ; that the surface of the head 

 and the body were slightly roughened with minute granulations, especially on the 

 thoracic and three last segments, which bore a number of minute black points, and 

 the rest of the upper surface was faintly freckled with rather darker green than the 

 pale gi-ound ; that the ocelli were black, and the anal shield fringed with a few fine 

 hairs ; and, as they matured, their glaucous tint gave way to a paler and more 

 yellowish-green. 



The slender pupa is three-quarters of an inch in length, two Hues across the 

 arched thorax, where it is widest, though the head, with its large prominent eyes, is 

 almost as wide ; the top of the head is a trifle flattened, and has a beak-like process 

 projecting forwards of a flattened triangidar shape, its base lying across the head 

 between the eyes ; the abdomen tapers very gradually towards the anal portion, 

 which ends in a prolonged and blimt flatttened tip, furnished with a circlet of 

 exceedingly minute recurved hooks ; the wings, antennae, and legs are plainly 

 developed, and the proboscis extended at full length down the abdomen, from which
