( •'537 ) 



Head and palpi black ; face dull whitish ; collar and front of pectns bright 

 yellow ; thorax black ; abdomen cinereous, whitish beneath. 



The form above described is the palest ; another <J has the white rostriform 

 blotch of forewing; invaded by smoky blackish scales, the snbmedian streak almost 

 obsolete, and on the hiudwings the veins black, the inner margin more thickly 

 black, and black scales running up along the veins ; but the underside is as white 

 as in the ty]ie form. 



The aberration siiJ/'/tm di Iters greatly : in the forewing the rostriform blotch 

 and the snbapical spot, which is much larger, are both yellow, the base of cell 

 being also overlaid with black scales ; in the hindwing the snbapical spot is of 

 ordinary size and only faintly yellowish, but the whole wing is suffused with smoky 

 black, the veins and marginal borders being denser black. Beneath, the two 

 blotches of forewing are yellowish, and the submedian streak white ; the hindwing 

 is nearly normal, but has all the veins thickly black, and the white marginal 

 blotches all large and well developed. 



ExiJanse of wings : 34 mm.

96. Heteriisia clarimargo spec. nov. 



The counterpart of H. salcini Butler, but rather smaller, 30 — 32 mm. in 

 expanse instead of 35 mm. Salvini, however, has in tlie hindwing a blackish 

 border running irregularly from the dark apical area to the anal angle ; this is 

 entirely wanting in clarinmrgo, but its place is taken by a few bright vinous 

 scales.

97. Heterusia tessellata spec. nov. 



Forewini/ : black, the markings pale primrose ; three costal streaks, at one- 

 sixth, one-third, and two-thirds respectively ; three streaks from base, one short 

 below costa, one along median vein, and one quite narrow along submedian vein ; 

 the first and second costal streaks and that along median run into an elongated 

 blotch, obliquely placed, lying partly in cell and partly on each side of vein 1 ; 

 fringe black with pale primrose mottlings above middle. 



Iliiidwiiiff : primrose, with broad black hindmargin and narrower inner margin ; 

 costa with three black blotches, indicating three bands ; first at base, with another 

 beneath it, forming a basal patch ; second acutely triangular, continued as three 

 separate black spots to middle of inner margin ; the third quadrate with a small 

 blotch below it, and four more in lower half of wing ; these blotches lie between 

 the veins; fringe black, broadly mottled with primrose, wliolly primrose round apex. 



Underside of forewing with the pale markings much developed ; a fourth 

 costal streak beyond the third ; a yellow marginal line from apex to vein 3, the 

 yellow mottlings of the fringe produced inwards across marginal line as acute 

 teeth ; veins G, 7, 8 shortly yellow to apex : hindwing yellow, with four black 

 curved bands, cut up by the yellow veins into irregular-shaped spots ; the spots 

 of the marginal series in the shape of a magnet with the yellow vein at centre. 



Palpi internally black, externally primrose ; face black, hairy ; fillet primrose ; 

 vertex, antennae, shoiilders, patagia, thorax, and abdomen black; tips of shoulders
