ARHODIA; DINOPHALUS; OPHIOGRAPHA. By L. B. Prout. 
whiter, with weak postmedian line, marked with darker spots on the veins, and a faint band proximal to it. 
Abdominal patch less ochreous. Sherlock River, West Australia. 
25. Genus: Arhodln Guen. 
Differs from Homospora in wanting the frontal projection and in having the 2nd subcostal vein of the 
forewing free. Perhaps all the known forms are referable to a single variable and widely distributed species. 
lasiocanvpa- A. lasiocaniparia Guen. (= subpurpurea Walk., rosalinda Th.-Mieg.) (2 b). The sexes differ in shape 
in a way analogous to that of Gastrophora henricaria, to which it is evidently really related. Porewing beneath 
with a dark mark on the discocellulars and a large blackish purple blotch midway between this and the distal 
reiractaria. margin. The type form has the ground-colour ochreous brown-grey. — ab. retractaria Walk. (= semirosea Walk.) 
carnea. has the forewing less ochreous, the hindwing strongly suffused with rosy pink. — ab. carnea Warr. is an extreme 
form with the pink of hindwing rather intense and the shadowy line wanting, the forewing also more fleshy 
intone. —- Larva with a rudimentary pair of prolegs on the 5th abdominal segment; smooth except for a 
projecting semicircular dorsal disk near anal extremity. South Australia and Tasmania to Queensland. 
ozora. A. ozora Stvinh. is smaller and paler, both wings very light ochreous grey with a very slight fleshy 
tinge, the markings of the underside not very strong. Not unlikely a mere aberration or local form, but the 
costal margin of the forewing looks slightly more concave and the distal margin anteriorly slightly rounder. 
West Australia, only the type known. 
26 Genus: S>iiBoplBaliis Prout. 
Nearly related to the following genus. Frons with a long horny projecting plate, rough-scaled laterally 
and terminating in two strong points, the interspace roundly concave. Tongue wanting (?). Hindtarsus of <$ 
with 1st joint dilated and hollowed, concealing a small comb of spines at proximal extremity. Abdomen long, 
especially in the Wings narrow. Only the type species is known. 
cyunorrhaea. D. cyanorrhaea Lower (2 c). Grey-brown, with the central area sometimes paler and of a more slaty 
tone, containing an indistinct brown median line, rather near the postmedian; the other lines blackish, the 
ante median remarkably oblique and zigzag from the hindmargin rather near the base to the end of the cell. 
N. Queensland and West Australia. 
27. Genus; Prout. 
Face with strong chitinous projection, which often terminates in a horny beak-like process below. 
Tongue develoj)ed. Antenna of <$ unipectinate. Head, thorax and femora densely hairy. Hindtibia in 
with 2, in $ with 4 spurs. Wings with distal margin generally crenulate. Forewing with 1st subcostal anasto¬ 
mosing with costal. Hindwing with costal and subcostal anastomosing in middle third of cell. Early stages 
unknown. All the species are Australian. 
serpentaria. 0 . serpentaria Guen. (= undulifera Walk.) (2d). Distinguished by the very complicated pattern of 
zigzag lines, which nearly meet at tlie veins and are more or less connected by longitudinal dashes on the 
veins. Base of hindwing white. ‘ Australia”. 
macrophyes. 0. macrophyes Prout (2 c). Lines much less zigzag than in serpentaria , though the ante-median forms 
an acute tooth outward behind the cell; postmedian fine, accompanied distally by a fine white line; the elon¬ 
gate dark marks between this and the fine white subterminal conspicuous. Hindwing pale proximally but not 
white. West Australia. 
diluUma. o. dilutaria IF air. (2 c) is a small species, with the distal margins nearly smooth, scarcely crenulate. 
Forewing whitish in the central area, otherwise suffused with brownish and with some black irroration: ante- 
median line deeply dentate, postmedian rather inconspicuous, being accompanied proximally by a band of 
red-brown shading; a short, ill-defined dark shade from costa midway between postmedian line and apex. 
postmaryi-' Hinclwing white proximally, brownish distally, with a dark postmedian line. •— postniarginaia Prout seems 
to be an aberration with less whitish central area. — Roebourne, West Australia. 
drakei. 0. drakei Prout (2 c). Differs from the other species in not having the frontal prominence produced into 
a beak below. Wings of a delicate grey, the hindwing slightly paler proximally; forewing with the lines black, 
the postmedian dentate; dark shades proximally to the antemedian and distally to the postmedian; median 
shade faint. Beaconsfielcl, Victoria, in November.
