Mr. J. Wood-Mason on Parantirrhoea Marshalli. 335 



before the middle of the discoidal cell and extending into the 

 apical angle ; "discoidal" vein in the same straight or slightly 

 curved line with the subcostal ; discocellular veinlet sinuous ; 

 the third median veinlet produced to a conspicuous tail. 



Antennae fine and distinctly clubbed. 



Female unknown. 



No Asiatic genns of Satyrinte presents us with any approach 

 to the remarkable arrangement of the two hindermost veins of 

 the anterior wings described above ; but in the South-Ameri- 

 can genus Antirrhcea we meet with identically the same 

 arrangement, the first median veinlet in the males of A. archcea 

 and its congeners running back to the inner angle, and the 

 submedian vein ending a considerable distance short of that 

 angle, though not nearly so far short of it as in the Indian 

 form, for which I propose the above name, in allusion to these 

 remarkable points of resemblance, reserving all further com- 

 parisons and comment until I shall be in possession of 

 specimens of the South- American forms. 



The species of the genus Elymnias alone exhibit the same 

 disposition of the three anterior veins of the posterior wings. 



Parantirrlioea MarshalU^ n. sp. 



^ . Wings above dark fuscous, suffused with rich deep 

 violet. 



Anterior wings with an outwardly and forwardly arched 

 subcrescentic pale violet or mauve band, commencing beyond 

 the middle of the wings at the costal vein, terminating at the 

 inner angle, and crossed obliquely by a series of three small 

 white spots disposed in a straight line parallel to the outer 

 margin, and placed upon folds of as many consecutive cells, 

 the last being between the two anterior median veinlets. 



Posterior wings relatively longer-tailed than in Melanitis 

 ismene (Cramer), with the membranous parts of the divergent 

 tails almost wholly formed by the produced wing-membrane 

 of the interspace between the second and third median vein- 

 lets, a very narrow anterior membranous edging only being 

 contributed by the interspace next in front, and with rather 

 more than the basal two thirds of their length in front of the 

 discoidal and subcostal veins ochreous. 



Wings below ochreous, obscurely striated with a deeper 

 shade of the same colour, and marked with a submarginal 

 series of inconspicuous brown specks, the probable rudiments 

 of ocelli. 



Length of anterior wing 1*16 inch, whence expanse = 

 2*4 inches. 



The female will in all probability prove to differ from the
