ARRHENOPHANES. . 295 
Antennae —3; basal joint without pecten; ¢ bipectinate, each pectination biciliate; 9 strongly biflabellate. 
Labial Palpi upturned, not reaching base of antennae, thickened with scales; terminal joint shorter 
than median, obtuse. Mawillary Palpi and Haustellum rudimentary. Ocelli absent. Head and Thora 
rough, the latter with posterior tuft. orewings widening outwardly from the base, costa slightly 
convex, apex obtusely rounded, termen oblique, not sinuate: neuration 11 veins (10 absent); 8-9 
stalked, 8 to termen; 7 separate; 8-5 somewhat approximate, from end of cell, 4 nearer to 5 than to 
3; 2 from beyond outer third of cell; an internal vein to between 5 and 6, no secondary cell; 1 basally 
furcate. Hindwings 1+, apex obtuse, termen and dorsum evenly convex, cubitus not pectinate: neuration 
8 veins, all separate; 4-6 parallel, 6 nearer to 5 than to 7, an internal vein to between 5 and 6; 
14 present, 1° basally furcate. Abdomen robust, hairy. Legs: front tibiae with epiphysis almost as 
long as the tibia; hind tibiae hairy, spurs well-developed. 
A genus of very robust and Bombyciform appearance, specially remarkable from the 
much greater development of the antennae in the @ than in the o, but, as the 
pectinations are biciliate in the ¢ only, the greater development of these pectinations 
in the 9 is probably merely structural and not functional; Busck records the larvae as 
living in Polyporus and making cases. 
The most nearly allied genus is Cnissostages Z. (oleagina Z.), which however differs 
in having FW: 12 veins, 9-10 stalked, and a furcate internal vein in both wings. 
[Paratuyris Hb. (“ Pharathyrides”) was founded to include three species: 1641 
perspicilla Stoll, 1642 cedonulli (Crmr.) Stoll, and 1643 pandiona (Crmr.) Stoll. Walker 
recharacterised the genus in 1855, including additional species, but omitting perspicilla 
Stoll, which he referred [Cat. Lp-Het. BM. 7 1740 (1856)] with a “?” to Dasychira 
Stph. Kirby included thirteen species in Parathyris Hb., marking cedonulli Stoll with 
a * as the Type of the genus; he replaced perspicilia Stoll in the genus, but with a 
«“?”, as sp. 13. Hampson [Cat. Lp-Phal. BM. 3 9 tf. 1 sp. 1194 (1901)], regarding 
the first species (perspicilla Stoll) as the Type of Parathyris Hb., disregards Kirby’s 
specification and describes Thyrarctia Hmsn. for the reception of cedonulli Stoll. 
Parathyris Ub., Kby., and Thyrarctia Hmsn. are synonyms with the common Type 
cedonulli Stoll, and a new genus (Arrhenophanes) is required for perspicilla Stoll. ]
