272 THE CANADIAN ENTOMOLOGIST. 



clypeus; width i.i mm. Cervical shield transparent, black dotted at 

 tubercles and edge. Body flat, green dorsally from the food ; a white 

 broken subdorsal line on joints 3 to 13, and double black lateral one 

 crossing tubercles ii. and iii. Feet colourless ; setje long, white. 



Stage V. — Head dark, the spottings obscured; width 1.7 mm. 

 Body purplish dorsally (in this specimen), with distinct yellow subdorsal 

 line on joints 3 to 13, double lateral black line and broken, pale yellow, 

 stigmatal one. Subventral region whitish. Setse long whitish ; tubercles, 

 except iii., minute. 



Stage VI. — Apparently interpolated ; width of head 2.2 to 2.5 mm^ 

 As in the next stage. 



Stage VII. — Head round, the apex below prothorax, clypeus high, 

 reaching the cervical shield in the ordinary position of retraction ; 

 antennse as long as mandibles ; whitish, with remote scattered dashes or 

 patches of dark brown, principally in a double line on each side of the 

 vertical notch and also in a parallel row across the centre of the lobe 

 obliquely ; width 2.7 to 3.0 mm. Cervical shield large, membranous 

 and transparent, so that the retracted head is plainly visible through it. 

 Anal plate concolorous with the body. Body a little flattened, segmental 

 incisures marked ; segments 3-annulate, the anterior annulet small and 

 not reaching the dorsum. Skin translucent, not strongly marked. 

 Greenish, a broken, yellowish white, subdorsal line above tubercle i.; a 

 similar stigmatal line ; slight whitish streaks in the lateral space ; a 

 double waved and broken lateral brown line covering tubercle iii., which is 

 much larger than the others and conspicuous. This line varies in 

 distinctness, sometimes being obsolete, represented only by the large 

 dark tubercle. Slight whitish markings subventrally. Tracheal line 

 white, its ramifications visible by transparency. Cervical shield slightly 

 brown dotted. Feet colourless, normal. Tubercles normal; on abdomen, 

 i. dorsad to ii., all small except iii., iv. + v., vi. single, vii. of three setae; 

 on thorax ia + ib, iia + iib and very large, iv. + v. Tubercles some- 

 times surrounded by blackish. The subdorsal and stigmatal pale lines 

 extend over joints 3 to 12. At the end of the stage the larva turns red 

 and seeks a place for spinning. The cocoon is composed of leaves 

 fastened together and bitten in an ellipse, the inside lined with silk. 



Food-plant. — The larvae live among the leaves of Capparis 

 cynophallophora, fastening them together with silk and hiding among the 

 skeletonized remains, or in an abode of fresh leaves united with silk.
