NYMPHALID.E. SATYRIN.E. PARANTIRRHCEA. 261 



The last genus of the Sa/yritiiE included by us in the Indian fauna contains but one species, 

 and is perhaps one of the most remarkable in tlie sulifamily. Mr. Wood-Mason notes : 

 " No Asiatic genus of SatyriiKE presents us with any approach to the remarkable arrangement 

 of the two hindermost veins of the forewing ; but, in the South American genus Antirrhcca, 

 we meet with identically the same arrangement, the first median nervule in A. archcea and its 

 congeners running back to the inner angle, and t!ie submediaa nervure ending a considerable 

 distance short of that angle, though not nearly so far short of it as in the Indian form. I 

 propose the name Parantirrhaa in allusion to these remarkable points of resemblance. The 

 species of the subfamily ElymniiiKz alone present the same disposition of the three anterior 

 nervules of the hindwing."

A. 'Right /oretving from the underside, natural size, to show the whole venation, and the inflected lobe of the 

 inner margin. B. Anterior portion of the s.Tme, much enlarged, to show the relations of the nervules to one 

 another : rt, costal nervure ; 1,2,3,4. terminations of the four branches of the subcostal nervure. C. Right 

 hindwing, from the underside, natural size. 



"Male: Forewing triangular; costal margin moderately and regularly arched ; apex 

 acute ; outer margin almost straight, being only just perceptibly convex ; inner angle rounded • 

 inner margin sinuous, being lobed at the base much as in the males of Clerorne and yEmona 

 genera of Morphines ; subcostal nervure four-branched, the first branch given off before, and 

 the second beyond, the end of the discoidal cell, the first, second, and third coalescing 

 successively and respectively with the costal nervure ; the first, and the second, and all three in 

 turn becoming free and running off at a tangent, like the costal nervure, to the anterior 

 margin, the fourth being perfectly free from its origin and running to the apical angle ; lower 

 disco-cellular nervule long, very slightly concave outwards, almost straight ; middle one not 

 quite half the length of the lower one, upper one rudimentary ; submedian nervure sinuous, 

 short, terminating near the inner margin at about the level of the junction of the basal and 

 second fourth of the length of that margin, being, in fact, hardly more developed than is the 

 internal nervure of the PapilionincE as compared with that of many Heterocerous Lepidoptera ; 

 the Jirsi tnedian nervule directed straight outwards and backwards, out of its normal course 

 to the inner angle, and supplying the place of the rudimentary submedian nervure. On turning 

 to the underside, it is seen that a narrow rounded lobe of the functional sutural area [ inner 

 margin ] about six times as long as it is broad, is folded back upon the under surface, to 

 which it is firmly adherent. This lobe occupies the middle two-fourths of the length of the inner 

 margin, and is thickly clothed on its surface and fringed at its free edge with firmly attached, 

 long, and somewhat raised modified scales, rendered conspicuous by their rich dark brown 

 colour and satiny lustre. The outline of this turned-up lobe is marked out on the upperside by a 

 curvilinear groove. Hindwing tailed, .subqnadrate, with four distinct margins, viz., a strongly 

 and irregularly arched costal margin, nearly straight external and hind margins, and an inner
