The CANADIAN ENTOMOLOGIST. 19 



Striae becoming irregular near the vertex where they meet. Colour pale 

 yellow. Diameter about 0.5 mm. Laid in a single layer, the eggs con- 

 tiguous to each other. 



First stage. — Geometriform. Head round, brownish. Body semi- 

 transparent whitish with a purple shade, and small black dots. Thoracic 

 feet black, the abdominal ones well developed only on joints 9, 10 and 13. 

 Later it becomes more as in the next stage in markings. 



Second stage — Head semi-transparent, almost colourless but with a 

 reddish-tinge ; ocelli black, jaws brown ; a brown line along the side : 

 width, about 0.6 mm. Body green, a distinct brown stigmatal line with 

 two more above it but less distinct. Another line in the subventral space. 

 A few short, black sette. Feet all concolorous with body. The larvae 

 walk like geometers. 



Third stage. — Head shining, pale whitish with two faint brownish 

 bands in front, divergent basally ; a distinct band at side of head covering 

 eyes, preceded by a fainter one ; mouth brownish ; width, 0.9 mm. Body 

 grass-green with five dark brown lines on each side, the upper ones 

 rather faint, the stigmatal one very distinct, the subventral one diffuse. 

 Between these last two is a broad white band. Feet all present, but the 

 two anterior pair of abdominal ones much smaller than the others . The 

 larvae still walk with a looping motion, but less decidedly than before. 



Fourth i-^a^^.— Head grass-green, shining, marked as before, but the 

 mouth whitish; width, 1.3 mm. Joint 12 slightly enlarged. Colour 

 grass-green ; a geminate, dorsal, brownish line, continuing the front lines of 

 head ; a pale, obscure, subdorsal and a superstigmatal line, each edged 

 with brownish alaove ; a broad dark brown stigmatal band, below which 

 the substigmatal ridge is white. Thoracic feet semi-transparent. The 

 spiracles on joints 2 and 12 are white. Later, a brownish-red band 

 appears in the centre of the white band. 



More rarely the head is very pale whitish-brown, marked as above. 

 Body reddish-brown, somewhat mottled with darker brown. Markings 

 the same, but there are six faint, narrow lines between the dorsal and 

 substigmatal ones. 



Fifth stage. — Brown form. Head very pale brownish, marked with 

 black on the clypeus, two broad lines divergent basally and three bands 

 at the side, connected by mottlings ; eyes black, jaws brovvnish, antennae
