obsolete. Larva with white oblique bands which are bordered with pinkish lilac anteriorly, strewn with small 
black ring-dots; horn black laterally. On Salix, Populus, Betula. — bombax B. & Benj. is a western race from 
Utah, both the wings much lighter, the black longitudinal streaks only of half the size. — una Skinner was esta¬ 
blished according to 1 aberrative $, bred in Brooklyn, darkened on all the wings without the yellowish-reddish 
colour and therefore looking like eremitus. 
S„ drupiferarum Abb. & Sm. (95 c) is exactly like the palaearctic ligustri. Thorax blackish-brown, tegulae 
light inside, edged with pinkish-white like the basal costal-marginal part of the forewing; submarginal area also 
light. Hindwing with a broad median band and a whitish margin before the dark marginal band. The nomen- 
clatural type flies from Canada to Georgia, to the west as far as the Mississippi, and is very common. — utahensis 
Edw. (= vancouverensis Roll.) is the western form which is much whiter and occurs in the western States from 
Colorado to Utah, California and Oregon. Larva with red oblique stripes bordered with white posteriorly; on 
Prunus, Pirns, Syringa etc. 
S„ dolli Ncumoeg. is a much smaller species, but it resembles the preceding species in the colour and 
scheme of markings, but the white costal-marginal part of the forewing is extended to the apex, distinctly 
separated from the greyish-brownish lower half by the black longitudinal streaks. Hindwing greyish-brown 
without the black discal and marginal bands. Arizona. — coloradus Sm. (95 c) is somewhat darker and shows 
a black submarginal line between the veins 2 and 5, which is absent in the nomenclatural type. Colorado; Utah. 
- australis Clark is still darker, head and mesothorax dark grey, the dark brown tegulae without the light border; 
hindwing also darker. Early stages unknown. 
S. sequoiae Bsd. (= coniferarum Wkr.) (95 c) differs from dolli in the costal part of the forewing not 
being lighter; antennae shorter than in dolli ; ground-colour more monotonous, more brownish; only the black 
sub marginal stripe in the anal-marginal part is bordered with whitish outside. Hindwing unicoloured 
brownish-grey. — engelliardti Clark (95 d) was originally described as a form of dolli. Thorax dark grey like 
forewing and not brownish, markings finer and less distinct. From Utah. Early stages not described. 
17. Genus: l^apara Wkr. 
Imago scarcely different from Sphinx, except the shorter proboscis and smaller palpi; larva quite 
different, without a horn and with longitudinal stripes, a triangular head, on conifers. Pupa without a free case 
of the proboscis. 
Type: bambycoides Wkr. 
L. coniferarum Abb. A Sm. (= cana Martyn ) (95 c). Greyish-brown, somewhat lighter in the anal portion 
of the forewing, the markings of variable distinctness, postmedian fragments of two transverse lines being most 
distinct; the discal longitudinal streaks may also be present or absent. Hindwing unicoloured light greyish- 
brown. Canada to Florida, to the west as far as the Mississippi. Larva green with 3 white longitudinal stripes, often 
speckled with oblong lighter or darker grey spots. It lives on Pinus, especially P. palustris. — pineum Lintn. is 
probably no distinct species, but only a monotonous extreme aberration, all the markings, transverse lines and 
discal longitudinal streaks being obsolete. Only 2 specimens known from the State of New York. 
L. bombycoides Wkr. (= coniferarum Harris, harrisi Clem.) (95 d) is smaller than the preceding species, 
likewise most variable, darker brown on the forewing, anterior transverse lines more distinct, the posterior ones 
more strongly dentate. Canada to Florida, to the west likewise to the Mississippi. The larva differs from that of 
coniferarum in the red face, it also lives on Pinus, especially P. strobus. 
L. halicarniae Stkr. (95 d) is a rare species, much larger than coniferarum, all the markings nearly extinct, 
so that often only 2 black discal longitudinal streaks are present beside a fine notched posterior transverse line. 
The type is a pathological specimen with shorter and broader wings. Florida. 
Subfamily: Ambulicinae, 
18. Genus: l*rotaml»ulyx R.&J. 
Proboscis extending almost to the centre of the abdomen; palpi and frons situate almost on a level; a 
transverse comb of hair between the antennae. Dorsal segments of abdomen distally spined; tibiae spineless; 
pulvillus present. Distal margin of forewing cut out below the apex. Abdomen with oblique lateral stripes. 
Part of the species are difficult to distinguish. 
Type: P. strigilis L.
