ASH SPHINGES. 547 
16. Sphinx gordi us Cramer. 
Usually feeding on the apple, the caterpillar of this species has been 
found on the ash, as well as on Myrica gale and M. cerifera. 
Larva. — Of a bright apple-green color, with a brownish vertical stripe on each 
side of the head, and seven oblique stripes on each side of the body, which are white 
and margined above with violet. The caudal horn is reddish brown. Length, 2£ 
inches. 
Pupa. — With a very short, detached tongue case. 
Moth. — Palpi reddish brown except the apex, which, with, the head, sides, and 
sometimes central part of the thorax, is gray. The rest of the thorax is blackish 
brown with black metathoracic tufts. The abdomen is ashy gray with a cen- 
tral black line and a broad tapering black band on each side, broken by four or five 
dull whitish cross-stripes. Under side of thorax and abdomen gray. The forewings 
are gray, clouded with brownish. The discal spot is small, white and triangular, 
and from it two fine black lines extend in along the cell and finally unite. The 
median vein and veins 2, 3, 4, 5, and 6 are marked with black, and there are black 
dashes between all the veins below the apex, the last forming the oblique apical 
streak. A curved ashy-brown shade crosses the wing at the basal fourth; another, 
from the costa a little beyond the middle, ends at the middle of the hinder margiu, 
and a third, crossing a little beyond and parallel to the last, is somewhat toothed on 
the veins. Outside of this a blackish shade line, bordered on each side with gray, 
is visible only on the hinder half of the wing. Au ashy-brown spot rests on the 
costa a little before the apex, leaving a gray shade on the upper side of the oblique 
streak. Fringes brown at the ends of the veins and white between. The hind 
wings are sordid white, with a central and broad terminal band nearly black. 
Fringes pure white. The under side of the forewings is brownish gray, and the 
fringes are as above. The under side of the hind wings is gray, with a narrow cen- 
tral and broad terminal band of dark brownish gray. (Fernald.) 
17. Daremma undulosa Walker. 
This species feeds on the leaves of the white and black ash, lilac, 
and privet (Ligustrum vulgare,) and, according to Eev. W. J. Holland, 
occasionally on the white and red oak. (Can. Ent., June, 1886.) 
Egg. — Pale green or aqua marine in color, spheroidal in form, the vertical 
diameter is four- fifths of a millimeter, one lateral diameter is two millimeters, and the 
other is one and two-fifths millimeters. The surface is very finely granulated and 
has pearly reflections. The eggs hatch in eight days. 
Larva. — The young larva is one-fifth of an inch long, of a very pale greenish yel- 
low color with fine hairs scattered over the surface. The caudal horn is large, 
straight, and pointed obliquely up and back at an angle of forty-five degrees with the 
line of the body, and is covered with a fine pubescence. It is smoky brown at the 
tip only, but before the first molt the brown extends nearly over the whole surface 
of the horn. 
The first molt occurs in from four to six days, after which the larva is one-third of 
an inch long, of a pale green color, the head being a little lighter than the body and 
having the surface granulated and a pale vertical stripe on each side. There are 
seven oblique stripes on each side of the body, and a longitudinal stripe of a whitish 
color but not plainly visible. 
The second molt is made in from three to five days, after which the larva* is three- 
fifths of an inch long, of a pale green color and with the stripes as before the molt 
but plainer, and there is added a series of reddish spots on the forward side of the 
oblique stripes where they cross the longitudinal stripe. The caudal horn is of a
