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. Boints 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 Bell port, 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. Ihe 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.
