Feet on joints 6-13. Thoracic feet colorless ; dorsal vessel dark green, 
no marks. The spines are arranged three on second annulet, the upper 
one forked, the two lower simple and short; one small point low down 
on third annulet; three on fourth annulet, the two upper forked ; two 
on each division of subventral fold, all simple, short. 
Last stage. —No change. Head 1.3 mm. The head and thoracic 
feet seem a little greener than before. 
Ultimate stage. —Smooth, waxy, scarcely shining, all pale whitish 
green, dorsal vessel dark. Segments indistinctly 3-annulate. Head 
concolorous with body, eye black; width 1.3 mm. Length 11 mm. 
The Y-spines are entirely absent. 
Found on young hickory leaves at Fort Lee, N. J., during the last 
of May. Single brooded. This is doubtless the larva briefly described 
in Dr. Packard’s 5th Report U. S. Entomological Commission, page 
317, as “Selandria sp.” 
Harpiphorus maculatus Norton. 
A specimen with three submarginal cells on one side and four on 
the other was bred from a larva on Potentilla Canadensis at Fort Lee, 
N. J. Head with a tiny brown spot behind the eye and dot at back of 
occiput on vertex. In ultimate stage head whitish, with a leaden 
patch on vertex. (See Can. Ent., XXVIII, 236.) The larva was 
intermediate between H. maculatus and Monostegia ignota in having 
but a trace of black spots on the head, and the imago was also interme¬ 
diate in the number of submarginal cells. 
Variety coryli, var. nov. 
This larva is single brooded, disappearing before the middle of 
June. Found not uncommonly on the hazel at Plattsburg, N. Y., and 
VanCortlandt Park, New York City, in some cases rather destructive to 
the plants. I suppose this larva to represent a distinct species and re¬ 
ferred to the larva as “5F” in Can. Ent., XXVII, 339. It differs in 
what seem good specific characters from the larva of H. maculatus , yet 
I do not find any differential points between the flies. 
Solitary, usually out straight, sometimes curled, sitting on the 
under side of the leaf. Head faintly testaceous, a diffuse leaden black 
patch on the vertex behind ; eye in a black spot; width 1.2 mm. The 
black spot reaches well down the side of the head, but the whole face is 
pale; a trace of white bloom. Thorax a little enlarged, abdomen 
scarcely tapering, slightly smaller posteriorly. Dorsum gray to spi¬ 
racles, uniform or centrally dorsally on abdomen nearly white; sub-
