X. eumedon Bsd. (= ortospana Drc. (98 E a) is similar to crotonis ciristor in the marking, smaller, of a eumedon. 
more brownish olive colour, the first postdiscal oblique line very strong, confluent with the second, the space 
between the lines 1 and 3 very light, bone-coloured. The 3 upper subterminal spots on the forewing are more 
or less confluent. Mexico to Brazil. 
X. rhodotus Bothsch.( = rhabdotus Oberth.) is very similar to eumedon, the grey abdominal stripe broad, rhodoius. 
parted by a scarcely darker colour, subdorsal ochreous spots at the base. The lines 1 and 4 of the fore wing 
are strong and black, line 4 proximally bordered with yellowish-white. All the spots on the hindwing are 
separated. South America. 
X. nabucliodonosor Oberth. (98 F b) has the same ochreous basal tufts on the abdomen as rhodotus: ndbucho- 
line 1 is thin, the space behind it as far as line 3 darker green, darkened into a blackish triangular spot at the donosor. 
inner margin, line 4 strong, the space between 3 and 4 dingy yellowish-grey, the following lines very feeble 
except the last, 1, 3 and 7 slightly undulate-dentate. Hindwing as in rhodotus. Bolivia. 
X. titana Drc. (= aristor Burm.) (98 F b) is smaller and more slender than the preceding species, of a titcina. 
more brownish tinge, the space between the 2nd and 4th oblique lines on the fore wing forms a bone-white band 
which is feebly parted by grey, the space between the 1st and 2nd lines very dark, almost black. Hindwing 
very pointedly produced, the spots somewhat confluent towards the apex. Mexico to Sa. Catharina. — f. 
indistincta Closs shows all the light markings of the body and of the forewing very feebly marked, especially indistincta. 
the double line extending across the thorax and abdomen. According to a 2 from Sa. Catharina. — Larva 
brown, more yellowish on the dorsum, the first segments inflated, a black white-ringed ocellus on the 4th ring, 
somewhat lighter oblique stripes on the other segments. On Spermacoce. 
X. muelleri Clark is allied with eumedon, resta and tersa ; body above olive brown with red-edged tegulae, muelteri. 
a red ventrum, thorax beneath orange. Forewing with a dark brown, slightly curved line from the inner margin, 
7 mm behind the base, to the apex, proximally bordered with light ; the cell before it and an area below it 
tinted red; a finer parallel line behind the line, and 2 fine lines before the margin. Hindwing as in eumedon , but 
the light submarginal band extends to the anal angle, and the dark marginal band is narrower. Length of 
forewing: 32 mm. Mexico (Misantla). 
X. resta B. & J. (98 F b) is very similar to a large tersa and intermediary between tersa and crotonis. resta. 
The grey dorsal band of the abdomen is only distinct on the first segments and parted by dark, light yellow 
tufts at the base, then a large black lateral spot, the segments 3—6 laterally ochreous. Shape of wings broader 
than in tersa, line 1 of forewing strong, 2 fused with it, 3 and 4 close together, the strongest line is the fifth, 
expanded into a spot at the inner margin. Spots of hindwing larger than in tersa. Venezuela, Peru, Argentina. 
X. tersa L. (98 F b) is one of the commonest Sphingidae, rather small and slender. Forewing mono- tersa. 
tonously brownish, line 1 is the strongest, the space between lines 3 and 5 somewhat lighter. Spots of hindwing 
well separated, the uppermost small. Tegulae inwards with a rusty yellow stripe, the abdominal sides quite 
golden ochreous as far as the anal apex, with 3 feeble longitudinal lines above. Widely distributed from Canada 
to Argentina. - tristis Closs is an insignificantly darkened form. —- Larva with strongly inflated thoracal seg- tristis. 
ments, the brown or blackish body with 7 black, white-ringed ocelli subdorsally, the first on the 4th segment 
being the largest, the ocelli are situated on a yellowish-white line, blackish oblique lines below it. It lives on 
Spermacoce and Manettia. Bahamas. 
X. suana Drc. (= evana Hmps.) (98 F b) is more monotonously coloured than tersa, more ash-grey, suana. 
or brown, abdomen not yellowish-red laterally. Wings not so elongated, the spots of the hindwing are much 
smaller and reduced in number. 
X. turbata Edw. (98 F c) is likewise very similar to the preceding species, the white stripe of the tegulae turbata. 
is inwardly bordered with dark olive. Fore wing coloured as in the preceding species, the 1st and 2nd lines 
forming a broad band towards the apex, lines 3—7 very fine, 4 slightly stronger than the others. Mexico and 
British Honduras. 
X. fosteri B. & J. (98 F c) is allied to turbata and robinsoni. Body above olive with a pinkish-grey fosteri. 
lateral stripe on the thorax and a brownish-grey median stripe; abdomen wood-coloured brown, grey at the 
base, with 3 indistinct dorsal lines. Forewing brown, dusted darker; lines 1 and 2 strong, more or less confluent, 
the 3rd fine, the 4th with vein-dots, 4 and 5 especially distinct between vein 4 and the apex; the tAvo distal 
lines feeble; a brown shadow behind the small black stigma. Hind\A'ing blackish-brown with a dingy pink post¬ 
discal band which is brownish towards the costal margin, lighter analwards. Length of forewing: 30 mm. 
Paraguay. 
X. ferotinus Gehlen (98 F c) likewise belongs to the Arsa-group, but it differs in its purer olive green ferotinus. 
colouring, the antennae being much thinner than in tersa and not white, but dark grey. Head and thorax dark 
green, laterally dark grey as far as the apex of the palpus. Abdomen marked as in tersa. Forewing with 6 
distinct oblique lines, lines 1 and 4 being the strongest, the space between 1 and 4 light brownish. Hind\A'ing 
less slender and pointed, the postmedian spots small, not yellow, but smoky brownish. Sa. Catharina.
