Ch. perpulchra Warr. (6 e). Totally unlike all other species, through its white hindwing and broad, perpulchra. 
regular dark borders. Underside similar, but with a dark streak along base of costa of forewing and a faint 
greenish postmedian line on hindwing. E. Peru: Huancabamba, Cerro de Pasco, very rare. 
18. Genus: Dicliorda Warr. 
Probably related to Phrudocentra, but distinguishable superficially by the shape and by the different- 
tone of the green colouring and the stronger white lines; structurally by the different palpus and generally 
more hairy breast, more tufted legs, etc. Palpus hairy, rather long, but with the terminal joint in the $ consid¬ 
erably less elongate relatively than in Phrudocentra. Antenna in the $ serrate or pectinate. Hindtibia of the 
d not dilated. Belongs chiefly to North and Central America and the West Indies, but one species has reached 
Peru and the Amazons and one very aberrant species from N. Argentina is provisionally added. 
D. rectaria Grote (6e). Deeper and more bluish green than iridaria, the white lines more slender, the rectaria. 
veins not whitish-mixed, the costal edge of forewing also with less white. Fringes green, scarcely paler than the 
wings. Texas (loc. typ.), Colorado. 
D. rhodocephala Prout (6 e) differs from rectaria in its redder head, Racheospila -like ornamentation rhodo- 
of the abdomen and obsolescence of the first line of the forewing. Jamaica. cephala. 
D. iridaria Guen. (= albolinea-ria Martyn, ined., remotaria Walk., consequaria II. Edw., latipennis iridaria. 
Hulst) (6 e). A pretty species with the postmedian unusually broad, somewhat shaded with yellowish on the 
proximal side, white longitudinal rays more or less strongly developed in distal area. Eastern United States 
and straggling into Central America. The larva has been found on sumach. — perpendiculata Warr., from perpen- 
Mexico, has the lines widely separated, on an average less broad, straighter, approaching illustraria except in diculata. 
size and colour. 
D. illustraria Hulst (= iridaria part., Pack., nec Guen.) (6 e). Larger than iridaria, the wings perhaps illustraria. 
not quite so fully rounded, purer green, the post-median less broad, a little straighter, the Avhit-e distal rays 
rarely well developed. Described from California, also inhabiting Arizona, etc. 
D. obliquata Warr. (6 f). This species and the two following form a separate group, with pectinate $ obliquata. 
antenna; on the whole smaller and with the lines more oblique, but quite similar in facies. In the present species, 
as in the two preceding, the underside has a dark inner-marginal spot behind the discocellulars, like that of 
many Phrudocentra , but smaller. Mexico (loc. typ.) and Costa Rica; perhaps occurs also on Trinidad with 
uniformis. 
D. ursiformis Warr. (6 f) lacks the dark posterior spot of the underside, but may possibly prove a form uniformis. 
of obliquata. The less convergent lines, with less iridaria -like edgings, separate it from iris. Described from 
Trinidad, known also from Venezuela, the Guianas and even Guatemala. 
D. iris Butl. (6 f) presents a distinctive appearance in the position of the lines and their yellowish edges, iris. 
The lower part of the face seems to be whiter than in uniformis and the pectinations of the $ may be a trifle 
shorter. Best known from the Amazons, the type from Rio Tapajos: occurs also in Colombia, at La Union, 
Carabaya, and I think meets uniformis in Surinam. 
D. porphyropis Prout (6 f). Strikingly distinct, not only in the purple and reddish markings of the porphy- 
forewing but also in the development of a moderate hindtibial process in the and the stalking of the 1st ropis 
median of the hindwing. The palpus, however, seems to bring it nearer to the present genus than to Phrudo¬ 
centra. $ unknown. Argentina: Missiones, the type only. Brazil: Alto da Serra, a rather larger d> here figured. 
19. Genus: I^eptoloplia Warr. 
Here commences a group of genera- with crested abdomen and almost invariably two-spurred hind- 
tibia in both sexes. In Leptolopha the crests are relatively weak and undifferentiated, whitish, forming — at 
least in pallidaria — a longitudinal ridge. Occur chiefly in Peru and the Amazon subregion. 
L. subaurea Warr. (6 f) is very striking on account of the golden-yellow colour of the greater part of subaurea. 
the wings. The type was damaged, so that the crests were not detected and the species has hitherto been 
misplaced. A second example, in beautiful condition, shows it to be in every detail a typical Leptolopha.

L. permagna Warr. has the same size as subaurea but the green colouring brings it nearer to the rest permagna. 
of the species. From them it differs in its large size, relatively broad wings, absence of reddish marking at
