﻿NYMPHALIN^. (Group EUTHALIINA.) 53 



two outwardly-oblique lines, which are joined posteriorly, then by a semihyaline 

 bluish-white band, a black triangular space, and then another triangular semihyaline 

 triangulate mark, the latter outwardly defined by a fine black line following the 

 discocellular veinlets ; beyond the cell is an outwardly-triangular semihyaline bluish- 

 white spot situated between the base of the lower radial and upper median veinlet ; 

 the disc is crossed by an inwardly-oblique semihyaline bluish-white baud, composed 

 of irregular shaped continuous spots disposed between the veinlets, and all defined 

 by the black slender veins and outer edges, those spots above the lower radial being 

 elongated, the three lower shorter and broader, the lowest small and constricted ; in 

 some specimens, of both sexes, the narrow upper white portion extends, opaquely, 

 along the costal border to the apex (as in the Fahrician type female specimen of 

 Gambrisius), and there is a more or less incipient white small spot in front of the 

 lower subcostal one. Beyond this bluish-white macular band is a submarginal and a 

 marginal black band, both bands being somewhat macular, the former with an inner 

 additional slender sinuous portion at its lower end ; the lower discal interspace 

 between the median and posterior margin being slightly suffused with pale lilac. 

 Hindwing crossed by a short black basal, a narrow inner subbasal, followed by a 

 broader outer subbasal band, then by a discal band of small dentate spots increasing 

 in size posteriorly, an outer discal series of slender double-pronged marks, the inter- 

 vening veins being black-bordered ; a submarginal row of acutely-pointed dentate 

 spots and a marginal lunulated band ; from the middle of the costa, between the 

 outer subbasal and discal band, are two short white lunular spots ; the upper discal 

 interspaces slightly suffused with pale blue. Underside much paler olive-green, 

 Forewiiui with all the markings similar, but less prominent. Hindwing crossed by a 

 slender black irregular wavy discal line, and a subbasal short line between the costal 

 and subcostal vein, followed by an inner discal series of very ill-defined black- 

 speckled lunules, then an outer discal series of pale bordered black-speckled duplex- 

 marks, the upper one of which latter is the largest and most prominent, afterwards 

 is a submarginal sei-ies of lunules and marginal spots, the latter being disposed at 

 end of the veins. Body above dark olive-green ; thorax and abdomen crossed by 

 black bands ; body beneath, palpi and legs olivescent-white ; apex of palpi above 

 olivescent-brown ; antennse blackish-brown ; eyes red-brown.

DisTEiBUTiON.^The late Captain Mortimer J. Slater (MS. Notes, p. 244) 

 remarks, " I met with this insect (P. Gambrisius) at Dacca, in the deepest jungle. 

 Its flight is rapid and dodgy, and in consequence is very diSicult to capture on the 

 wing." Mr. L. de Nicdville (Butt. Ind. ii. 147) records it from Eastern Bengal, 

 Shillong, Assam, Silhet, Cachar, and Upper Tenasserim. Mr. Wood-Mason obtained
