HETERUSIA. 21 



yellowish-white belt, interrupted upon the nervures by ultramarine streaks ; a dash across 

 the base, a large spot at the end of the cell, two spots and a dash between them crossing 

 the lower half of the disk, and an irregularly bisinuatcd subapical belt, divided by the veins 

 into seven more or less ovoid spots, white ; the discal spots with pale blue internal borders : 

 secondaries black, crossed in the middle by a very broad externally angulated bright-yellow 

 belt, which unites with a white costal streak running to the base ; base, apex, outer border, 

 and veins beyond the yellow belt metallic blue ; two small spots beyond the cell and two 

 between the second and fourth median branches white : thorax dark brown ; the shaft of the 

 antennae, crest, two spots at the back of the collar, the tips of the tegulae, metathorax, and 

 two basal segments of the abdomen blue, changing in certain lights to green ; internal angles of 

 tegulse white ; remaining segments of abdomen yellow, with lateral black dots. Wings below 

 nearly as above, but the white spots tinted with sulphur-yellow ; all the veins blue-bordered : 

 body below dark green ; legs brown ; coxae white-spotted ; segments of venter white-edged. 

 Expanse of wings 2 inches 10 lines. 

 Cachar (Grant) ; Silhet. 



In the specimens from Silhet the white spots of the subapical series upon the primaries 

 are smaller than in the type. 



Heterusia virescens. (Plate LXXXIII. fig. 3.) 



Primaries above olive-green, crossed before the middle by a slightly arched white belt, 

 which is intersected by the nervures and bordered externally with ultramarine-blue ; a blue- 

 edged white dot at the end of the cell and three across the lower half of the disk ; five 

 unequal subapical white spots forming an interrupted series : secondaries black, crossed near 

 the middle by a broad arched white belt ; base streaked with green ; veins upon the disk and 

 a submarginal irregular streak from anal angle to costa cobalt-blue ; a dot at the end of the 

 cell and a subapical series of three spots white : thorax olive-green, spotted with blue, and with 

 a white dot at the inner angle of each tegula ; antennas blue ; basal segments of abdomen 

 green, remaining segments pale yellow. Wings below black, with blue veins and streaks, 

 white margins broader than above : pectus blue, varied with green, and with two white spots 

 in front; venter olive-green, banded with emerald-green and white, and with ochreous 

 margin ; anal segment opaline. Expanse of wings 2 inches 9 lines. 



India. 



This species is intermediate in character between the preceding species and H. cedea ; 

 the primaries much resemble those of H. edocla. 



Heterusia dulcis. (Plate LXXXIII. fig. 4.) 



Similar to H. edocla of Nepal, but differing in the larger spots upon the disk of 

 primaries ; secondaries also with an abbreviated bright yellow dash across the outer part of
