INTRODUCTION
The present study is the continuation of the faunistic work on the different families of lepidopterous insects collected from the Namdapha Wild Life Sanctuary, Tirap distr!ct, Arunachal Pradesh, by Dr. S. Biswas and party during the year 1981. The paper deals with the four families of butterflies viz. Pieridae, Danaidae, Satyridae and Lycaenidae, including 11 species and subspecies in 8 genera, 4 spec ies and subspecies in 2 genera, 7 species and subspecies in 4 genera and 10 species and subspecies in 10 genera respectively.
Evans (1912) for the first time reported a list of butterflies over'the Abor expedition mainly from north Assam and the south Siang division of Arunachal Pradesh. This includes 10 species of Pieridae, 5 species of DanaidaeJ--8 species of Satyridae and 22 species of Lycaenidae, together with 7 species of Papilionidae, 20 species of Nymphalidae, one species of Erycinidae and 2 species of Hesperiidae. Betts (1950) recorded 16 species and subspecies of Pieridae, 7 species and subspecies of Danaidae and 39 species and subspecies of Satyridae from the Bali· para, Frontier Tract and Subansiri division of Arunachal Pradesh in North-East India. Varshney and Chanda (1971) reported 6 species of Pieridae, 2 species of Danaidae and 1 species of Lycaenidae from Arunachal Pradesh.
Presently, 11 species and subspecies of Pieridae are recorded for the first time from Namdapha Wild Life Sanctuary of which 6 species and subspecies are new records from the entire Arunachal Pradesh viz. Delias belladonna lugens Jordan, D. thysbe pyramus (Wallace), Pieris napi mDntana Verity, P. canidia indica Evans, P. brassicae nepalensis Doubleday and Eurema hecabe contubernalis (Moor).
Distribution: India 1 Sikkim, Assam and Arunachal Pradesh; also Bhutan and Northern Burma.
Remarks. The subspecies commonly known as 'The Hill Jezebel', is not rare in status. Betts (1950) reported the species belladonna from north-east India without mentioning the. subspecies. In the present work the subspecies lugens is recorded for the first time for the species belladonna from Arunachal Pradesh. Material examined: One C, Namdapha, Gibbon land, 6.iv.1981 (5. Biswas and Party col!.). Wing exp. 80 mm.
Remarks: The subspecies popularly known as 'The Great Orange Tip', is common in status. It is recorded for thc first time from Namdapha Wild Life Sanctuary, Tirap district. Evans (1912) reported the species from Siang division, while Betts (1950) recorded the species from Subansiri division. Hubner,Verz. bek. Schmett.,p. 95. One species with two subspecies are known to occur from this area under this genus of which one is represented here. The othet sub· species is pirenassa Wallace recorded from Assam. Remarks: The subspecies popularly known as 'The Chocolate Albatross', is common in status (Talbot, 1939). Varshney and Chanda (1971)  Remarks: Popularly known as 'The Common Grass Yellow' , the subspecies is very COlnmon in· status. It.is recorded for the first time from Namdapha, Tirap discrict as well as from the entire Arunachal Pradesh. Evans (1912)  Remarks: The subspecies popularly known as 'The Dark Blue Tiger', is common in status. This species is well known as melissa Stoll (1781), but according to Talbot (1947)  Material examined: One ,j, 1 ~, Namdapha, Burma Nala, 24.iv., 1,j, Zero camp, 9.iv. and 1 ~ , Deban, 7.iv.1981 (S. Biswas & party col1.). Wing exp. 94-100 mm. Two species with subspeci~s under this genus are known from Arunachal Pradesh which are dealt with hereunder.
Remarks: The subspecies commonly known as 'The White-Edged Bush Brown', is rare in status. It is recorded for the first time from Namdapha, Tirap district, Arunachal Pradesh.

Genus Yptbima Hubner
1S18. Ypthima Hubner,Zutr. Samml. exot. Schnlett.,1 : 17. Five species with subspecies are known under this genus from Northeastern region of India of which two are new records from Arunachal Pradesh which are represented here. The other two are Y. sakra austeni (Moore) and Y. nareda newara Moore. Evans (1912)

Remarks:
The subspecies commonly known as 'The Striped Ringlet', is rare in status. It is recorded for the first time from Namdapha as well as from the entire Arunachal Pradesh. Hubner,Verz. bek. Schmett.,p. 56. Out of eighteen species and subspecies known under this genus from North Eastern Indja, three species and· subspecies are represented here.
Genus Anthene Doubleday 1847. Anthene Doubleday, List. Spec. Lep. Ins.,B,.it. Mus.,2 : 27. Out of two species and subspecies known from this area under this genus, one species with subspecies is represented here.
One species under this genus is represented in the present study.
Remarks: The species commonly known as 'The Orchard Tit', is not rare in status, except in Andamans where it is very rare. It is recorded for the first time from Namdapha, Tirap district, as well a~ from the entire Arunachal Pradesh. SUMMARY The paper deals with the systematic account of four families of butterflies Pieridae, Danaidae, Satyridae and Lycaenidae collected from the Namdapha Wild Life Sanctuary, Tirap district, Arunachal Pradesh.
Out of 11 species and subspecies of Picridae, 4 species and subspecies of Danaidae, 7 spe,cies and subspecies of Satyridae and 10 species and subspecies of Lycaenidae all of which are recorded for the first time from Namdapha Wild Life Sanctuary, 6 species and subspecies of Pieridae, 3 species and subspecies of Satyridae and 9 species and subspecies of Lycaenidae are new records for the e,ntire Arunachal Pradesh. While one species and subspecies of Satyridae has been reported for the first time from India.
