PAMPHILA AOTiEON. 137 



yellow line on either side, and enclosing a pale longi- 

 tudinal line along its middle. A narrow yellowish line 

 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 colour 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 brown, — greenish in the oldest ones, with 

 lines stouter and paler, without 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 underside of the tenth 

 and eleventh segments are conspicuous as in P. lineola, 

 sylvcmus, and comma, and appear to be a peculiarity of 

 the whole genus. This white substance is spread out 

 at the tail end of the larva of P. Actceon, when it has 

 formed its chrysalis case." 



As regards my four larvse, 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 ventral prolegs ; that the surface 

 of the head and the body was slightly roughened with 

 minute granulations, especially on the thoracic and 

 three last segments, which bore a number of minute 

 black points, that the rest of the upper surface was 

 faintly freckled with rather darker green than the pale 

 ground ; that the ocelli were black, and the anal shield 

 fringed with a few fine hairs ; and that 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 lines across the arched thorax, where it is 

 widest, though the head, with its large prominent eyes,
