LÉPIDOPTÉROLOGIE COMPARÉE 379 



The epicraaia of the head are yellowisii, heavily biack ^potted 

 above, but becoming purplish about the eye area. The eyes them- 

 selves are situated on black spots and the space within them is 

 somewhat yeliow. 



The Irons is lightly marked and the two outermost of the row 

 of four spots bear weak hairs. The mouth parts except the labrum, 

 are brownish and this is paler save toward the edges. 



The antennae differ from those of deuhami, for they hâve the 

 base pinkish, with nidications of yeliow. The club and next joint 

 are dull purple and hâve a yeliow ring between them. 



Body. Perhaps in this forni the 3rd abdonnnal segment is the 

 broadest. There is a gentle taper from this in both directions. 



The larva is more or less stone coloured with, generally, a faint 

 purple flush. The whole larva may be suffused with blackish as 

 in denhami but never to such an extent. 



The medio-dorsal stripes are very clear and distinct, but like 

 the others, they vary in breadth and tend to break and disappear 

 at the anterior trapezoidal tubercles. The edging may be quite 

 dotted in character. The space between thèse stripes is not equally 

 broad, being broadest at a yeliow bar. This irregularity varies 

 in différent spécimens and the stripes may be, in some cases, 

 almost parallel. In many, when the edging is weakened, the hlling 

 is yeliow, but when strong and continuous, the filling in is very 

 much like the ground colour. When the stripes are not greatly 

 broken, they are nearly parallel on the thorax and the last abdo- 

 minal segments. 



The subdorsal stripe shows signs of disappearance, and the 

 edging and filling in are quite irregular, more specially near the 

 position of the transverse bars. 



Similarly, the supraspiracular stripe is irregular, with a deta- 

 ched and broken edging, and a filling in that is scarcely obser- 

 vable and in some cases total ly obscured with black dots. The 

 space between the upper edging of this and the spiracular stripe, 

 may be blackish suffused.
