ERIOPUS. By W. Warren. 193 



below, not reaching above subcostal vein: outer line distinctly crenulate, followed by a pale fulvous-edged 

 space; veins towards termen whitish; all the pale tints tinged with fulvous yellow instead of reddish as in 

 retrahens. Like the last, an Indian species, extending into Kashmir. 



0. tripartita Leech (44 d). Forewing grey brown, darker in median area; inner and outer lines thick, tripartita. 

 black, double, filled in with whitish; submarginal line continuous, whitish, preceded by a dark shade and 

 with dark suffusion beyond it above vein 5; all three stigmata with thick blackish outlines, the reniform 

 with some white externally; hindwing dull luteous, the terminal area, especially towards apex, fuscous, 

 beyond a thick dark outer line. Described by Leech from $$ only, from Pu-tsu-fong, W. China. 



38. Genus: Eriopus Tr. 



Tongue well-developed; palpi upturned, the second segment fringed in front with long hair ending 

 in a point, the third smooth, porrect; frons smooth; antennae variable; thorax clothed with hair and 

 scales, with spreading crests on prothorax and metathorax, and a double crest between on mesothorax; 

 legs with thick wisps of hair; dorsum with basal tufts; forewing with apex prominent; termen crenulate, 

 angled at vein 4 and concave above; a tooth of hairlike scales projecting from inner margin before anal 

 angle. — Larva (of the 3 species known) on ferns; the genus therefore and many of the species widely 

 spread. Type Eriopus jumntina Cram. 



According to the different structural modifications in the antennae, and the varying development 

 of the tufts of hair on the legs of the $$, the genus is divided into many sections, to some of which sub- 

 generic names have been applied. The following table embraces 12 of the 14 palaearctic species. 



Sect. II. Antennae of <$ with shaft thickened towards base and with a clawlike or simply pro- 

 tuberant projection on upper side. 



C. The projection at Y 3 from base, followed by short scale teeth; the tibiae and 1 st segment of 

 mid and hind tarsi fringed with long hair. 



a. The projection long, clawlike, phaeogona limps. 



c. The projection short, humped (Agabra Walk.), aethiops Btlr. 



D. The projection at %, without scale-teeth. 



b. The projection slight. 



a 1 The projection followed by long bristles; fore and hind tibiae and 1 st segment of their tarsi 

 fringed with long hair; midtibiae, the inner spur, and nearly the whole of the tarsi with 

 very large hair-tufts, juventina Cram. 



b 1 The projection followed by ciliations; the tibiae, 1 st segment of tarsi, and inner spur of mid 

 tibiae fringed with long hair, rivularis Walk., and albolineola Graes. 



Sect. IV. Shaft of antennae of $ hardly thickened at base, downcurved at middle, with no protu 

 berance. 



A. The curve at middle with scale-teeth and long bristles; a tuft of 4 erect hairs on upper side at 

 its extremity; the tibiae, the spurs, and 1 st segment of the tarsi long haired, argyrosticta Btlr. 

 and maillardi Guen. (Rhoptrotrichia Btlr.). 



B. Shaft of antennae thickened and finely serrate at middle; the tibiae, the first segment of tarsi, 

 and the spurs of mid tibiae fringed with long hairs, albomacula Leech. 



D. The curve at middle of antennal shaft simple. 



a. Mid and hind tibiae and 1 st segment of their tarsi fringed with very long hair, duplicans 

 Walk. (Hyperdasys Btlr.). 



Sect. Y. Antennae of <$ sinuous at middle but not thickened nor ridged with scales. 



A. Foretibiae and 1 st segment of their tarsi with large tufts of hair; mid tibiae with very large 

 tufts, the inner spurs long haired; 1 st segment of tarsi with very large tufts of hair both above 

 and below, the terminal segments with the tufts above only; hind femora with fringe of long 

 black hair, the hind tibiae and 1 st segment of tarsi long haired, repleta Walk. 



Sect. VI. Antennae of $ simple, ciliated. 



A. Forewing with termen distinctly angled at vein 4. 



d. Mid and hind tibiae and 1 st segment of tarsi moderately fringed with hair above. venata
