poecilastis. 
meterythra. 
94. Genus: Xeiiopscustis Meyr. 
Tongue fully developed; frons with rounded prominence with a corneous plate below it; palpi 
porrect, slender; antennae of $ lamellate, with short ciliations; thorax and abdomen smoothly scaled, without 
crests; forewing elongate triangular; the apex blunt; the termen obliquely curved; no areole; 7, 8, 9 stalked 
from upper angle of cell; 10, 11 both free, from cell; hindwing with normal neuration. Type X. poecilastis 
Meyr., the only species. 
X. poecilastis Meyr. (21 k). Forewing redbrown; subbasal line yellowish white from costa to sub¬ 
median fold, with a patch beyond it from cell to inner margin; a yellowish white vertical inner band with 
irregular edges; a yellowish white striga from middle of costa and two on inner margin; an outer broken 
band, consisting of a costal spot, a band on discocellular constricted at middle, and an oblique streak 
below it to tornus; an irregularly zigzag yellowish white subterminal line from apex to vein 3; fringe 
yellowish white, redbrown at middle and above tornus; hindwing redbrown, the base and inner margin 
pale yellow; fringe yellow intermixed with redbrown. Duaringa, Queensland. 
95. Genus: Iflypocalitiisiii Hmps. 
Tongue fully developed; frons smooth; palpi obliquely porrect, the second segment stout, well fringed 
with scales in front, the third short, smooth; antennae of ciliated; thorax and abdomen smoothly clothed 
with hair, without crests; forewing elongate; the apex blunt; the termen obliquely curved; neuration 
normal. Type H. meterythra Hmps. 
H. meterythra Hmps. Forewing flesh colour tinged with ochreous and dusted with brown, partly 
suffused with yellow brown, the median area with pale pink; subbasal line waved, brown externally white- 
edged; inner line brown, inwardly edged with white, angled basewards in cell, then outwardly oblique and 
waved; outer line dentate lunulate, brown, outwardly defined by white, bent outwards below costa, excurved 
to vein 4, then incurved; subterminal line pale, preceded by redbrown suffusion and followed by a 
diffuse dentate line, except at apex which is whitish; a row of strong black terminal striae; fringe pale red; 
orbicular and reniform stigmata with pink centres and slight white annuli edged with dark brown; the 
orbicular round, connected by streaks below subcostal and above median vein with the reniform, which 
is defined on outer side by small dentate brown marks, that at upper extremity extending to outer line; hind¬ 
wing bright brick red; the fringe yellowish white. Described from a single from the Punjab. 
8. Subfamily Erastrianae. 
In the previous subfamilies vein 5 of the hindwing of the imago is subobsolete, a false not 
a true vein (whence Guenee’s term Trifidae), and the larva has 5 pairs of prolegs; in the following 
(Guenee’s Quadrifidae) this vein is equally well developed with the rest, while in the larva one or 
both of the two first pairs of prolegs is aborted or absent. The insects composing the present subfamily, 
the Erastrianae, have all, as far as our present knowledge goes, larvae in which the prolegs are defi¬ 
cient, and nearly all have the radial of hindwing strongly developed. They are small insects, -—- some 
quite small and of tender structure, —often gaily coloured, and flying by day, and more numerous in the 
warmer tropical climates. They agree with the Amphipyrinae in having spineless tibiae and the eyes 
naked, without cilia; in some of the weaker forms the tongue is more or less aborted; the larvae feed 
usually on low plants and grasses; a few on lichens or on cocciclae; pupating in a spun cocoon above 
ground. Of the numerous small species very many of the larvae still remain unknown, and their generic sub¬ 
division is necessarily empiric.
