surface intensely marked, the brownish-grey marginal band forms a sharp inward angle between 4 and 5. 
Mexico to Peru and Surinam. - pallescens Closs, according to Gehlen who possesses the type, is a slight pallescens. 
deviation with more uniformly brown lines and a darker under surface, hindwing with but one broad discal 
band beneath. Described from Peru (Pozuzo). 
X. loelia Drc. (= aglaor Schs., laelia Drc., neoptolemus Bonningh.) (98 E e) is extraordinarily near loelia. 
to libya and forms a transition to the following neoptolemus. The forewing (mostly) lacks the cellular dot as 
well as the subapical black dot at the costal margin. Hindwing somewhat narrower with a more reddish median 
band, the black margin more regular and invariably narrower than the reddish band; the vein dots beneath 
are much less distinct, the marginal band is less distinct and much less angled. Mexico to the Amazons. - 
heinrichi Gloss, according to Gehlen, is only a form of loelia with differently shaped wings which are somewhat heinrichi. 
shorter with a straighter distal margin; the dark areas of the wings exhibit a greenish tinge: Abdomen with a 
bright yellow lateral stripe. Described from the Amazons. — Young larva green, adult larva brownish ochreous, 
with a series of darker dorsal spots, blackish-brown subdorsal lines, a black, white-ringed ocellus on the 4th 
segment and dark brown lateral oblique stripes. It lives on Spermacoce (Rubiacea); it conceals itself by day. 
X. neoptolemus Stoll (= trilineata Wkr.) (98 E e) is similar to loelia. Eorewing more monotonous and neopto- 
browner. Band of hindwing of a much deeper and brighter red, broader than in libya and loelia, reaching to the lemus 
costal margin, the proximal margin convex, more sharply defined than in loelia. Much redder beneath than 
the said species. From Mexico to Surinam. — - trinitatis Closs is smaller and has shorter wings of a darker trinitatis. 
colouring; the red band of the hindwing is narrower and not so carmine, but more yellowish-red, the black 
basal area and the distal band not deep black, but browner. Described from Trinidad. 
X. pyrrhus R. & J . (98 F f) is very closely allied to the following thyelia, but much larger; the light band pyrrhus. 
with the double line on the forewing is broader, the line distally bordering on this band gradually widens from 
the apex to vein 4; the distal margin is less rounded. Merida (Venezuela), South-Eastern Peru. 
X. thyelia L. (= eson Mkr., theylia L., spec. A. Bonningh.) (98 F f) is a very characteristical smaller thyelia. 
species; fore wing brownish-yellow, the costal-marginal half except the light apex more rusty brown with two 
slaty black lines from the base of the inner margin to the apex, the space between them filled with rusty brown, 
a light longitudinal band below them with 2 indistinct lines; hindwing grey with 2 postmedian rows of vein- 
dots. This nomenclatural form flies from Ecuador to South Brazil and Paraguay. — salvini Drc. was examined salvini. 
by Gehlen and M. IT ering ; it is the northern form from Mexico to Colombia. Wings more slender, the double 
line, which mostly shows a tendency to coalescense in thyelia , is distinctly separated, the light band narrower; 
the costal-marginal half is darker, more monotonous, the light apical area beneath more distinctly defined, the 
two longitudinal lines confluent and indistinct. 
X. jordani Clark (98 F f) is a peculiar small species near to the preceding ones, at once recognizable jordani. 
by the brownish-black basal area being sharply cut away, the whole costal part remaining light yellowish; the 
double lines of thyelia do not terminate at the base, but behind the first third of the inner margin, behind which 
there are 2 subterminal lines parallel to the margin, the distal third of the inner margin very dark. Hindwing 
light grey. Costa Rica. 
61. Genus : I*lianoxyla R. & J. 
Very near to Xylophanes and separated by a large tuft of scales on the 2nd palpal joint inside, which 
only occurs in palaearctic species. Distal margin of forewing irregular, indented between 5 and 3. Only 1 species: 
Ph. hystrix Flclr. (98 F f) is a qxnte unmistakable species with crenulate wings. Ground-colour olive hystrix. 
black with lighter olive green areas, a yellowish-white basal inner-marginal spot and a similarly coloured oblique 
line from the first third of the inner margin towards the apex; the line turns more reddish behind the lower 
cell-end to the costal margin, broader, notched and traversed by blackish notched lines; a black triangle before 
the anal angle, distally bordered by a short white notched line. Hind wing black with 6 small light yellowish 
sulphur-coloured postmedian spots and an inner-angular spot. Mr. Gehlen had the kindness to give us 1 
specimen of this extremely rare species for having it figured; only known from the Amazons. 
62. Genus : Celerio Oken. 
This well-known genus containing the palaearctic Cel. euphorbxae and gallii chiefly differs from the 
preceding genus in the antennae not being uniformly thin, but distally thickened. Generally of a stronger build, 
abdomen not so long and slender as in Xylophanes. Distal margins of the wings entire. Five representatives 
in America, two of which have to be considered as forms of palaearctic species. 
Type : C. gallii Rottenbg.
