214 TRACHEA. By Dr. M. Dkaudt. 
T. parcata Sm. (31 a) is of a more yellowish ground-colour than the preceding, with much less 
distinct markings, without the whitish irroration and without the black streak connecting the coniform macula 
and the posterior transverse line; the undulate line is only conspicuous by the contrast of the greyer marginal 
area and forms a W. Hindwing dull brownish-grey. Yellowstone Park. 
T. unita Sm. (31 b) is somewhat larger than the two preceding, in the central area brown, with 
double transverse lines filled up with whitish, connected by a black prolongation of the apex of the coniform 
macula; the maculae are large, in white rings and surrounded with an intense black, the oblong ring-macula 
touches the centre of the reniform macula; before the white undulate line with a distinct W in the centre small 
dark spots. Hindwing greyish-brown with a darker marginal band. Canada, Oregon. 
T. spaldingi Sm. (= umbrifacta Hmps.) (31 b) is marked very much like unita, but it is more bluish- 
grey mixed with brown, the transverse lines are not filled up with whitish, the black submedian streak is broadly 
shaded with brown, between the undulate line and the margin shaded with red-brown. The whitish hindwings 
are brownish, more intensely so on the veins and margin. Utah. 
T. centralis Sm. (31 b) is very similar to unita , discernible by the anterior transverse line distally 
forming a very long tooth on the submedian fold; intense bluish-white irroration is arranged as in cinefacta. 
Hindwing light brownish, on the veins and margin darker. Oregon, Sierra Nevada. 
T. turbulenta Hbn. (= arcuata Wkr.) (31 b). Forewing red-brown mixed with blackish-brown, in 
the central area darker, behind it lighter, except the costal-marginal part, with a black basal ray, the transverse 
lines bordered with reddish, and small lighter reddish maculae, the coniform macula varying in size, occasionally 
extending to the postmedian line; the light undulate line is very indistinct, analwards parted by a dark streak. 
Hindwing greyish-brown, towards the margin darker. Expanse of wings: 34 to 44 mm. Eastern and Central 
States as far as Florida. •—- The larva is narrowly striped black and white, on the ventrum reddish white, with 
a velvety black neck-shield, and on the two last rings with round white spots; it lives on Smilax. 
T. tusa Grt. (31 b) is very similar to turbulenta. more purple brown and grey, in the basal area olive- 
brown submedianly as far as the posterior transverse line, the transverse lines indistinctly double, in the marginal 
area darkened, traversed by the light undulate line. Hindwing yellowish brownish-grey. From California. 
T. indocilis Wkr. (= remissa auct.) (31 c) recalls the palearctic P. obscura (= gemina, cf. Vol. Ill, 
p. 168) in its more variegated forms. Fore wing brownish-grey, mixed with red-brown, in the central area 
dark purple brown as far as the submedian fold, with a basal ray, indistinctly double transverse lines, and black 
and white vein-dots behind the distal line, with a strong black submedian connecting streak, and lighter ringed 
maculae; the whitish undulate line being proximally shaded with brown exhibits a distinct W as far as the 
margin, behind it there are blackish triangular spots on the two folds. Hindwing brownish-grey, towards the 
margin darker. Canada to New York. 
T. mactata Gn. (31 c). Forewing brownish-grey, strewn with black, postmedianly lighter, with a 
black basal ray, double transverse stripes filled up with whitish and submedianly connected by black: the large 
maculae are centred brown, the light undulate line with a W is proximally bordered by brown sagittae. Hind¬ 
wing brownish-grey with a bent postmedian line. Canada to Colorado. — The form alleeto Sm. (31 c) is only 
in the central area feebly tinted brownish, otherwise grey and black. From Alberta, British Columbia, Dakotah. 
T. ferida Sm. (31c) is somewhat larger than the preceding, more mixed with red-brown and blackish- 
brown, the hindmarginal half of the central area much darker; the double transverse lines filled up with grey, 
the undulate line only composed of small whitish lunae, otherwise marked like the preceding. New Foundland. 
T. separans Grt. (= ferens Sm.) (31 c) is similar to ferida, greyer, strewn with dark brown, at the 
costal margin, in the central area down as far as the submedian fold, and in the marginal area except the 
apical part darkened with purple-brown, the dark-centred maculae and the embedment of the double 
transverse lines more whitish, before the white undulate line with a W there are small black sagittae. H indwing 
yellowish-brown with a central spot and postmedian line. New York, Wisconsin. -— The form Iona Streck. 
(= runata Sm.) (31 c) is darker in the central area as far as the hind-margin, but towards the costal margin 
somewhat lighter, in the postmedian area lighter, particularly towards the hindmargin. Canada; New York; 
Washington. 
T. perpensa Grt. (31 c) is browner than the preceding, the double transverse lines filled up with 
a hardly lighter colour, the ring-macula is very long and oblique, above open and below connected with the 
reniform macula, the latter distally with a small white luna; the whitish undulate line is faded, behind it there 
are long black internerval streaks. Hindwing light brown, towards the margin darker. New Mexico, Arizona. 
T. divesta Grt. (31 d) is a light reddish ochre-brown species, in the central area somewhat more reddish, 
with a black basal ray, single transverse lines being on the averted sides bordered with whitish, submedianly 
connected by an intense black; the lighter yellowish maculae are surrounded by black; before the whitish 
undulate line proximally with small black sagittae, behind it with blackish triangular spots on the folds. Hind- 
wing light yellowish-brown. The $ is greyer. Canada to Colorado and California.
