ed to it outside above; in distinction from innus, the light oblique apical streak is slightly bent and is 
situate at the end nearer to the margin than to the undulate-linear spot which is attached to the 
costal margin behind the centre. Hindwing cinnamon-red with black and light anal markings. Erom Florida 
to Bolivia and South Brazil; West Indies. Larva unknown. 
H. ramsdeni Clark is closely allied to parce and shows the same marking; smaller, with a more ob¬ 
tuse and shorter apex of the forewing; the costal-marginal spot of the forewing containing the undulate lines 
is merely a small light brown spot with traces of lunar markings; the silvery mark is only a fine angular 
mark; a broad dark brown line extends from behind the centre of the inner margin towards the costal mar¬ 
gin. Hindwing redder than in parce. Length of forewing: 29—30 mm. Cuba. 
H. acuta R. <£• J. Body similar to that of parce, but of a more olive tint. Eorewing narrower than 
in parce, more monotonously coloured and more sepia-blackish; the two costal-marginal spots are more lead- 
coloured, the posterior one without the undulate lines of parce and inuus ; a lead-coloured inner-marginal spot 
below the silvery mark; distal area transversely striated black; the light apical oblique line is absent, a 
lead-coloured spot before the centre of the distal-margin. Hindwing rusty-red with a blackish-brown mar¬ 
ginal band. Length of forewing: 32 mm. Amazons (Rio Madeira); Chanchamayo (Peru). 
H. inuus R. & J. (= galianna Btlr., lycastus Wkr., parce Bonningh., brethesi Kohler) (98 A e) is ex¬ 
ternally very similar to parce, but easily discernible by the oblique light apical line which is longer and quite 
straight and the end of which is nearer to the undulate-line spot than to the margin; this costal-marginal 
spot is mostly more reddish-yellow than in parce. The total colouring is deeper and brighter cinnamon- 
red; distal margin of forewing much less convex. Mexico to South Brazil and Paraguay. The larva has the 
usual Sphingid shape and is green with light subdorsal lines and orange-red spiracles, horn short, blackish-blue. It 
lives on Ambelania tenuiflora, an Apocynea, and turns red before the pupation. 
37. Genus: Stolidoptera R. J. 
Very near to the following genus Aleuron from which it differs in the palpi not being angled laterally; 
antennae long and slender, with a long terminal hook; stings of the posterior tergit-margins arranged in one 
row. Margin of forewing irregularly lobed, costal margin of hindwing very convex and of the same green colour 
as the forewing, in distinction from the otherwise dark hindwing. Only 1 species: 
St. tachasara Drc. (98 A e) is an unmistakable species with dark moss-green forewings, a somewhat 
lighter apex, the submarginal band with a lead-coloured reflection, and with quite indistinct darker trans¬ 
verse markings, which are partly filled with a lighter colour especially at the inner margin. Hindwing mono¬ 
tonously blackish-brown excepting the green costal lobe. Larva unknown. Mexico to Venezuela. 
38. Genus: Protaleurou R. & J. 
Head tufted, eyes ciliated. Palpi very large, angled outside as in Aleuron. Otherwise similar to the 
preceding genus, but the hindwing without the lobe at the costal margin. Only 1 species: 
P. rhodogaster R. <fc J . Eorewing somewhat like that of St. tachasara, but not so strongly lobed, short¬ 
er dentated. Dark olive green with 3 antemedian and postmedian transverse lines being distinct and blacker 
only towards the inner margin. Hindwings dark olive brown like the body above. Very remarkable for its 
bright pinkish carmine ventral side. Only 1 J from Ecuador seems to be known hitherto. 
39. Genus : Aleisrosi Bsd. 
Distinguished by enormously developed palpi which are angled laterally. Head and thorax with a 
central ridge. Eyes small, ciliated, the slender antenna with a long terminal hook. The feeble spines of the 
posterior tergit-margins not in one row. Distal margin of forewing irregularly lobately dentate. 
Type: A. carinata Wkr. 
A. carinata Wkr. (= chloroptera Bsd., philampeloides Fldr., orophilos Bsd.) (98-A e) belongs to the 
two species with black abdominal bands, though mostly only 2 or 3 basal ones are visible, the others being 
covered underneath the segments which are pushed one above the other. Eorewing. olive brown with a 
straightly cut off oblique light reddish-brown apical part and a similar median band behind the discal dot; 
hitidwing light reddish-yellow with a black apical part and median band. The dark dentate transverse, 
lines of the <$ are not present in the $, but there are only traces of 2 straight lines, one being submedian, 
the other postcliscal. Prom British Honduras to Bolivia and Rio de Janeiro. 
A. ypanemae Bsd. is similar to carinata, but the abdomen is without black bands. Unmistakable on 
the forewing by the triangular white hyaline spot being situated in the angle betw'een vein 6 and 7
