STERRHA. By L. B. Prout. 
225 
S. phaeocrossa Prout (23 a). Structure much as in maculata or with tarsus shorter; stalking of 2nd ■ phaeocrossa 
subcostal of hindwing normal (to about y 2 its length). Variable, but easily recognizable by its dark terminal 
border, etc. Smaller and paler than ocnera, a defined median band developed, sometimes strong, underside 
almost as sharply marked as upper. Distributed in Malaya, also known from Tonkin; type from Penang. 
S. halmaea Meyr. ( = prosaula Prout olim, err. det.) (23 a). Decidedly variable, sometimes coloured halmaea. 
nearly as in phaeocrossa, sometimes paler, but never without some pinkish or reddish tinge. Structure much 
as in the two preceding. By a misinterpretation of Guest’s very brief description, I recorded this species (Lep. 
Cat., pars 63, p. 386) as pyrosaula, but I have since learned from a specimen in the British Museum that the 
reference was really to Scopula lydia. halmaea is distributed from Queensland to Tasmania. The typical form 
has only faint indications of dark subterminal spots. — ab. epicrossis (Meyr. M. S.) nov. has conspicuous dark epicrossis. 
spots at the tornus and between the radials of the forewing, with faint — or even conspicuous — connective 
shading, more or less recalling phaeocrossa Prout or marginata Swinh. 
S.fucosa Warr. (23 a) is, as Turner says, “a small, delicate and inconspicuous species, but very distinct fncosa. 
in the pale rippled ochreous markings, absence of fuscous scales, and antenna of , which is serrate and with 
long tufts of cilia; liindtibia of very small, not dilated, tarsus of about the same length. Queensland. 
S. costaria Walk. ( = albicostata Turn., ohm, nec Walk.) (23 a). There was formerly much confusion costaria. 
regarding this species and inversata, but it has been cleared up. costaria is the greyer (less pinkish) of the two, 
with the costa on an average less sharply whitish; the vertex is whitish, whereas in inversata it is dark. The 
hindleg is quite different, the tibia short and slender, tarsus a little longer, slender. Porewing with all the sub- 
costals stalked beyond the areole. Widely distributed in Australia, from Queensland (type) to Tasmania. 
S. isomorpha Meyr. (23 b). <$, 16 mm. Differs from albicostata only as follows: antenna filiform, isomorpha. 
ciliations 1; posterior tibia very short, tarsus as long as tibia; wings greyer, with a pale postmedian band, 
2nd line consisting of a series of black dots, subterminal forming a narrow grey fascia; cilia whitish, with 
an obscure grey line”. One specimen, from Mount Lofty, S. Australia. Venation nearly as in inversata, the 1st 
subcostal of the forewing stalked appreciably beyond the 5th, but that is a redder species, with quite different 
hindtarsus. 
S. inversata Guen. (= albicostata Walk., costaria Turn., olim, nec Walk.) (23 b). For the differentiation of inversata. 
the true costaria see above. Costal edge of forewing and front part of thorax above strikingly whitish. The hindleg 
of the has never, I think, been described, though Turner keys the species among the group with liindtibia 
more or less dilated and distorted”; tibia short, with a slight tuft at the end, tarsus rather long, greatly dilated 
(recalling that of the Palaearctic filicata Hbn., Vol. 4, pi. 4 f), tapering to a very small point at the end. Fore¬ 
wing with all the subcostals stalked beyond the areole, the 1st beyond (generally much beyond) the 5th. Distri¬ 
bution as wide as that of costaria and perhaps including also Port Moresby, but I suspect an accidental intro¬ 
duction there. Guenee’s type was erroneously believed to come from Brazil; Walker’s was from Sydney. 
S. catopolia sp. n. (23 b). In the ground-colour and the weak markings reminiscent of inversata, but mtopolia. 
with the costal border of the forewing dull purple instead of whitish buff. Vertex similarly darkened. An¬ 
tennal fascicles of very long (at least 3), slender; midtibia normal, liindtibia with strong pencil and heavily 
fringed, sharply bent near its end, tarsus very short, with its 1st joint slightly hairy. Abdomen beneath 
whitish, and even on the upperside with some whitish admixture; in $ with buff-tinted lateral tufts on 3rd 
and 4th segments. More pinkish than halmaea, ciliation still longer, hindleg different. Remarkably like 
crinipes (23 i) except in the leg-structure. British and Dutch New Guinea: Hydrographer Mountains (type), 
Kumusi River, Snow Mountains and Mt. Goliath. 
S. iodesma Meyr. (23 b). 16 mm. Whitish, sprinkled with faint whitish-ferruginous; 1st line iodesma. 
ferruginous, rather irregular, not reaching costa; 2nd line thick, ferruginous, bisinuate, not reaching costa “; 
terminal line incomplete; fringe whitish. Hindwing with the postmedian band broadened, “an interrupted dark 
fuscous terminal line; cilia ferruginous-whitish”. Brisbane, 1 specimen (Turner suggests “probably” South- 
port). Likened somewhat to Scoptda innocens. 
S. stenozona Lower. Ochreous-whitish, forewing sparsely irrorated with dark fuscous; a well-marked stenozona. 
dark fuscous, dentate postmedian line from 5 / 6 costa to % hindmargin, continued on hindwing. Broken Hill, 
New South Wales, 1 $. Lower adds that there are small terminal dots on both wings and a faint dark cell- 
dot on the hind wing. 
S. argophylla Turn., founded on 2 $$ from Evelyn Scrub, Herberton, N. Q., and measuring 18 and arqophylla. 
20 mm, is said to be readily distinguishable from the following by the grey head. Shining white, without cell- 
dot or irroration; costal edge of forewing grey; both wings with 3 slender, finely dentate lines. Is it an aber¬ 
ration of the following ?
