colour of the forewing as well as the orange colour of the hindwing is paler; stigma of forewing smaller, fringe 
more distinctly speckled. — Larva red with two whitish lateral lines, the upper one of which is traversed by 
oblique stripes. Likewise on Gaura. 
P. clarkiae Bscl. (= victoria Grt.) (98 D e) resembles gaurae in colouring and marking, but it has less clarkiae. 
long wings with a more convex distal margin, especially of the hindwing, and the anal angle is not produced: 
median band of forewing broader, more rounded distally and not so oblique. Hindwing lighter yellow than in 
juanita. The whole lepidopteron looks more Bombycid-like by the stouter abdomen, like the species of Hae- 
morrhagia — Larva not described, but it is reported to live on Clarkia. In the Pacific States: British Columbia 
to California. 
P. flavofasciata Wkr. (98 D e) differs from the other species in the black body on which only the head flavo- 
and thorax above as well as the apex of the abdomen are straw-coloured. Fore wing olive brown with a scantily fasciaia. 
grey-scaled postdiscal band; hindwing yellow with a black basal and marginal band. Eastern Canada and 
New England. —- ulalume Stkr. (98 D e) has almost entirely black hindwings in the typical form with a traceable ulalume. 
triangular yellowish-grey postdiscal band which becomes broader and more yellow in transitional specimens, 
but never reaches the inner margin as in the typical form. Oregon, British Coulmbia. — rachel Bruce, founded rachel. 
upon one specimen, seems to be an intermediary form with a brighter and broader band on the hindwing than 
in ulalume. The larva is said to resemble that of Sph. abbotti and to live on Epilobium. Colorado. 
59. Genus: Eiiproscrpinus Grt. & B. 
Very similar to the preceding genus, only separated by the absence of the paronychium and pulvillus. 
Moreover, the terminal hook of the antenna is somewhat more suddenly bent down and thinner. Only 2 species: 
Type: E. phaeton Grt. & R. 
E. phaeton Grt. <L R. (= erato Bsd.) (98 D e) to a certain degree resembles P. flavofasciata extern- phaeton. 
ally, but the under surface and the hind wing are white. Fore wing scantily scaled olive grey, more densely 
scaled in the basal part and marginal area, with a discal streak at the cell-end and a postmedian transverse line 
indicated by vein-dots. Hindwing with an equably broad black marginal band. Abdomen with yellowish- 
white lateral tufts. South California. 
E. euterpe Edw. has similar whitish lateral tufts on the abdomen. Ground-colour more brown, not euterpe. 
blackish, the marginal band less contrasting and cut in deeper than in phaeton, and the marginal band of the 
hindwing is convex in the middle. Antennae scaled white, otherwise very similar to phaeton. It appears to be 
extremely rare. Likewise from South California. 
Subfamily: Ghoerocampinae. 
60. Genus : Xylophancs Hbn. 
This naturally composed genus contains an immense number of very slender, mostly rather large 
Sphingid species with narrow pointed forewings and a long, pointedly ending abdomen. Antenna slender, not 
thickening towards the end, with a long thin terminal hook. Eyes mostly ciliated. Tibial spurs unequally long, 
the exterior ones short; pulvillus and paronychium present. The larvae are thinner in front, generally with 
ocelli on the thoracal segments; they mostly live on Rubiaceae. 
Type: H. anubus Hbn. 
X. depuiseti Bsd. (98 D e). Olive green; abdomen with two rows of very faint brown dorsal dots on depuiseti. 
each side of which there is a row of light golden dots. Fore wing with two ante median and 3 postmedian oblique 
transverse lines, the 2nd postmedian line being feeble, the 3rd bearing fine vein-dots; a black stigma at the 
cell-end; the feeble subterminal line ends at the anal angle. Hindwing with a blackish median and marginal 
band and white-speckled veins. Brazil (Espiritu Santo, Sa. Catharina). 
X. adalia Drc. (98 D f) is very similar to the preceding species, but the lines of the forewing are stronger, adalia. 
and a black subterminal patch is between the veins 4 and 5; the fringe of the forewing are here also distinctly 
speckled white as far as the apex, in depuiseti only a little near the anal angle. The apex of the fore wing is not 
so sharply falcately produced. Under surface distinctly golden yellow. Panama (Chiriqui). 
X. ploetzi Mschlr. (= drucei Rothsch.) (98 D f). Likewise very similar, but the subterminal black spot ploetzi. 
on the forewing is absent, the stigma at the apex of the cell is white and the fringe of the forewing speckled 
white between vein 4 and the anal angle; the transverse bands are as strong as in adalia, excepting the most 
exterior one. Under surface yellowish green; abdomen with a fine dark median line. Surinam; British Guiana.
