lowish, shields concolorous ; shaded with smoky blackish between the pale lines which are 

 subdorsal, broken lateral, stigmatal and narrow subventral. Tubercles small, blackish in 

 pale rings ; setae black, stiff. Feet normal, not strongly plated. Later the color becomes 

 green, a broad purple brown subventral band between the stigmatal and subventral white 

 lines ; joint 2 in front faintly testaceous. 



Stage II. Head whitish, thickly dotted with black in a patch on sides of lobes and one 

 on vertex ; rounded, held obliquely ; width about .6 mm. Body moderately elongate, ends 

 contracted, normal. Whitish with green tint; traces of brown intersegmental dorsal line; 

 broad subdorsal and stigmatal and narrow wavy lateral white lines, not \'ery bright. A 

 broad brown black subventral band a little interrupted anteriorly and weakened about the 

 thoracic feet. Feet pale, tubercles black. 



Stage III. Head white, thickly dotted with purple and black on vertex and patches on 

 sides, held obliquely, antennae distinct, black spotted, width .9 mm. Body moderate, a 

 little flattened, flatly outstretched, anal feet narrowly triangular, divergent. Green, addorsal 

 white dots edging the dorsal vessel; subdorsal line white, not rigid, narrow, waved; sides 

 besides irregularly streaked in white. Tubercles black, ii the largest; anal feet black pow- 

 dered ; setae black ; no shields. 



Stage IV. Head purplish white, the upper half white, thickly mottled and spotted in 

 black; tubercles black, antennae white, black spotted; width i.i to 1.3 mm. Body held 

 flatly extended, anal feet square behind, colored like bai^k. Gray brown, black dotted reticu- 

 late ; dorsal line geminate, black, crinkly, tubercles i and ii black, just above the white 

 subdorsal line which is slightly black edged above. A faint white lateral line, black edged. 

 Tubercles black, iv conspicuously so and surrounded by white, the remains of a svibstigmatal 

 band which appears also as a dash on the anterior parts of the segments. Feet pale waxj-

 thickly with pale ocherous and black, black on the vertex and a curved band edging the disk 

 of face ; epistoma and bases of antennae whitish, tips of antennae ocherous ; width 1.8 mm. 

 Body equal, a little flattened, held flatly, feet moderate. Ocherous brown, speckled with

 marks on anterior edges of segments 6 to 9 and less bright ones on 5 and 10, edged behind 

 with black shading which runs back in an irregular geminate dorsal line, distinct on the 

 thorax and joints 10-13. ^ heavy black lateral shade looped down segmentarily below the 

 spiracles. Thoracic feet pale, abdominal ones purplish mottled with white. Tubercles 

 small, black, elevated slightly. A series of black ventral marks anteriorly on the segments 

 composed of a double arrow-shaped streak joined into a blunt X-iuark, more or less contin- 

 ued over subventral area to the lateral black marks. 



Pupation among leaves. Larvae from Kaslo, British Columbia. 'J'hey fed on
