Body lustreless blackish, segments 6-annulate with rows of short, blunt, 

 pale points on second and fourth annulets, about six on each side. 



Tracheal line pale ; feet on joints 6-12, 13. Eats the whole leaf on 

 the edge. 



Stage II — Head pale, faintly brownish, eye black with a very faint 

 dark shade reaching upward. Body whitish translucent, colored by the 

 food, the points blunt, fleshy, dark at tip. 



Stage III — Head very pale brownish, eye narrowly black. Body 

 translucent waxy whitish, segments 6-annulate; the points whitish ; no 

 marks. Incisures folded, tracheal line white. 



Stage IV. — Head pale brown, eye black. Body moderately trans- 

 lucent, dull whitish with a tinge of yellowish and green, the folds of 

 skin whiter. Points obsolete ; no marks or, in some, a small black 

 patch laterally on third annulet and another on anterior subventral fold, 

 more or less distinct. In some the points are still visible, pale, rarely 

 distinctly defined by dusky dots. Spiracle on the second annulet. 



Stage V. — Head pale, finely brown dotted, eye black. Segments 

 6-annulate, smooth, no points seen. Skin thin, the body uniformly 

 green from the blood, dorsal vessel dark, outlined by a little green fat, 

 not contrasting strongly. A black patch on the anterior subventral fold 

 and sometimes another laterally. Tracheae evident, their ramifications 

 visible nearly up to the dorsal vessel. Thoracic feet pale ; anal flap 

 smooth. Abdominal feet on joints 6-12, 13. The larva is now very 

 green, differing markedly from the preceding stages. A single example 

 from Bellpcrt, Long Island, had a black dot on the thorax, subdorsally 

 on the second annulet of joints 2 and 3, one on the anterior subventral 

 fold of joint 3 and one at base of each thoracic foot. The paired dusky 

 translucent patches in annulet 1 were also noted. No ultimate stage ; 

 cocoon in the ground ; single brooded. This larva is possibly a dimor- 

 phic form of H. albido variata, but the food plants differ and the slight 

 imaginal characters seem correlated.

The following tables have been prepared by Mr. Ashmead for his 

 forthcoming revision of the genera of saw flies and he has kindly given 

 me a copy of them for use here.
