This hawk-moth we have found in the egg and different larval stages 
on the willow at Brunswick through July and August .Some indi- 
viduals became much belated. A specimen found at Providence. 
tember 28, pupated October 1, and the moth appeared during the last 
week of the following June. 
Larva.— Head conical, granulated, with a yellow (sometime- a white) line meeting at 
the apes : -even oblique lateral yellowish lines on each ride, from the middle of tin- first 
one (which is fainter than the others) a line passes forward to the front edge of the 
prothoracic segment, converging towards its oppo- 
site line: the last line is broadest and mod 
tinct, reaching to the base of the caudal horn, 
which is lilac green ; spiracles deep lilac or black ; 
thoracic feet lilac and reddish. Length, .; 
In the stage before the last, length, 25 mm . — The 
body is more closely granulated ; the lateral 
stripes less distinct ; the thoracic segments not 
so small iu proportion to the head, and there is a 
_ . , _ subdorsal double row of reddish spots : the apex

9. Halesidota agasthii Packard. 
Mr. Stretch has in California reared this species (now believed by Mr. 
Henry Edwards to be the same as H. maculata Harris) from the willow. 
I copy his description of the larva, as it appears to differ from our larva 
iu being usually black. What he describes as a variety is like a larva 
of H. maculata we have found on the sycamore. 
The cocoon is obtusely oval, tolerably compact and composed chiefly 
of the hairs from the body of the caterpillar, with but a small amount 
of silk in its composition. The larva is double-brooded, and feeds on 
the willow; the first brood appears on the wing in June, the second 
being full-fed about the middle of October, and disclosed from the 
pupa early in the spriug. 
H. agassizii differs from the other species of the genus found in the 
United States, in the Absence of all tendency to semi-transparency in 
the anterior wings, such as appears in the thinly scaled tessellaris and 
edicardsii ; or to silvery markings, as in the case of carya? and arcjen- 
tata ; the costa is also less rounded at the apex than in any of the 
species mentioned, but the larval characters clearly retain it in the 
genus. 
Larva. — Head, body, and prolegs entirely black. Abdominal legs pale dirty yel-
