9. Family: Eupterotida. 



'I'lii- f«w species of Eupterotid/ie which must be dealt with among the Palearctic I>;pi(Joptera are trop- 

 icjil, with t)ic cxccptioii of two, and belong to the Indian fauna. No representative of this almost exclusively 

 tropical family is found in Hurope or Western Asia, or in the entire Mediterranean area. It is therefore un- 

 necessary to draw attention to more than the most important characters. The Eupterotids, alwo known as Htrich- 

 iiopterygids, Phialids, or Janifls, are a large but well defined family, in structure and faeies resembling the 

 Saturnids and Hombycids. They were formerly united with the Lafswmmjridat:, for instance by Hkkki<;h- 

 ScHAFrKR. The family containB forms of considerable size, some of them being hardly inferior in expanse 

 to the large tropical Saturnids. The smallest species are at least of medium size. The antennae of tlie ^5 al- 

 ways with very long dense pectinations, those of tfie U often only with short f>nes. Palpi at most of medium 

 lejigth, slightly upturned and densely hairy. Tongue small or absent. Ah regardis venation the position of 

 vein 5 is characteristic, this vein originating on both wings in the middle or even close Uj the upper end of the 

 cross-vein. In the forewing vein I is simple at the base or forms a rounded fork. V'eins d to 9 usually on a 

 common stalk, 10 as a rule absent. In the hindwing vein 8 is free from the base, or connected with the an- 

 terior margin of the cell by a short transverse vein. The frenulum is absent or in rare cases feebly develoj>ed, 

 at most somewhat more strongly in certain $$. Hind tibiae with two or four spurs. — The larvae are as yet 

 not well known. They are cylindrical, bearing tufted hair, the dorsal tufts especiallj' being ver}' long. Warts 

 ojily slightly developed. In faeies the larvae resemble those of the Lasiocampifis and Arctiid*. Pupation 

 takes place in a dense cocoon as in the Saturnids. 



All tlw; genera of Kapterotidttf. treated as Palearctic, as well as all the species except two, aj<- typical 

 epresentatives of the Indian fauna, and only concern us here becaiisc thr-y occur at the bou)id;ii\- of our Pey^Jon. 



1. Genus: Cjiaiiisa Walk. 



Palpi upturned to the centre of the frons, and densely scaled. Forewing broad, costal margin evenly and 

 slightly convex, apex pointed, rectangular in the ,^, somewhat produced in the ^4, <listal margin slightly convex, 

 inner margin feebly convex, hindwing elongate but broad, apical and anal angles distinct, distal margin mod- 

 erately curved, as in the forewing entire and with long fringes. In the forewing veins 3 and 4 rather wi<iely 

 apart, 5 before the middle of the discocellular vein. 6 from the upper angle of the cell, 7, 8 and 9 stalked. In 

 the hindwing veins 6 and 7 from the upper angle of the cell or stalked. I^egs densely hairy, median tibiae 

 with two long spurs, liind tibiae with four. — The genus occurs in Southern Asia, one species, however, also 

 being found in the Palearctic districts of the Himalayas. 



G. postica Walk. (29 e). Head dark brown, body brownish grey. Wings lighter gn-y with brownish pos'tco. 

 markings and similar fringes. In the forewing a small black di.scal spot, two subbasal and tlu-ee discal wavy 

 brown curved lines, as well as a sharp black-brown double band running from the apex to the inner margin 

 and being only divided by a narrow grey wavy line. Hindwing with three discal wavy transverse bands and 

 a somewhat sharper simple submarginal line, beliind which is a row of black-brown dots. On the underside, 

 instead of the transverse band of the forewing and the submarginal line of the hindwing there is a further wavy 

 curved hne. In the Palearctic Region found in Kashmir (Kangra, Kulu), also flistributed throughout Anterior 

 India and Ceylon, everywhere abundant. 



2. Genus: .iplia Walk. 



Palpi upturned to the centre of the frons, broadly scaled. Antennae very regularly pectinate, ends 

 of the pectinations in a straight line from the base to the apex. Forewing broad, apex pointed, rectangular 

 and slightly prolonged, distal margin moderately curved, forming a distinct angle with the nearly entireh- 

 straight hind margin. Hindwing almost circular. In the forewing vein? 3 and 4 close together from the lower 

 angle of the cell, 6 from the upper angle, 7, 8 and 9 stalked. 10 usually absent. In the hindwing veins 3 and 4 

 as in'the forewing, 6 and 7 stalked, 8 connected with the anterior margin of the cell by a very short transverse 

 vein close to the base; vein 5 from the middle of the discocellular vein in both wings. Legs den-sely hairy, 

 middle and hind tibiae with moderately long spurs. The genus is distributed from Japan to Southern Asia, 

 and represented in the Palearctic Region by two Japanese species. All the species are of medium size and 

 have on both wings a sharp oblique band with Ught edges. 



A. tychoona Bull. (29 e, f). A species varying greatly in the ground-colour. The lightest specimens iyctioona. 

 are almost entirely yellow, Avith even a greenish tinge, the dark ones brownish red to ohve. The most common 

 form is brownish with a slight greyish tinge. On the forewing the sharp blackish oblique band distally edged 

 with yellow runs from the apex to the middle of the inner margin, on the hindwing straight across the middle; 

 forewing with two subbasal and two discal dentate bands, widened to form spots at the inner margin and inter- 

 rupted before the middle, beside a small black discal dot ; in the marginal area two blackish wavy Hnes. Hind-
