spot in cellule 6, almost coalescing with blotcli ; a row of 

 minute postmedian vein-dots near termen, arising from a 

 thick dash on costa ; still minuter terminal vein-dots. 



Hind iving without basal or autemedian markings; discal 

 patch very much smaller than on fore wing, reaching from 

 SC^ almost to hinder end of DC^ slightl}^ concave on distal 

 side, the discocellulars in its middle ; postmedian row of 

 dots more proximal than on fore wing, especially posteriorly, 

 terminating in a spot on SM^, but with none costally ; an 

 extremely shadowy macular greyish band just proximal to 

 the postmedian ; fringe spotted at the vein-ends. 



Underside similar, but with the postmedian wanting, 

 except for the costal spot of fore wing, which here gives 

 birth to a rather weak^ but rather thick, lunulate-dentate 

 subterminal greyish line, which on both wings shows some 

 minute vein-dots on the (distal) points of the teeth. 



N. Burma : Hpare Valley, near the Chinese frontier, 

 5500 ft., 29 Aug., 1922 {Capt. Arthur E. Swann). Type in 

 coll. Jj. B. Prout, kindly presented l)y Rev. C. R. N. Burrows, 



A very fine species, evidently near tridentifer a ^hxii larger, 

 with much larger blotches and with quite different antenna. 



12. Macaria unigeminata, sp. n. 



S .—28 mm. 



Face with rather sharp, white-mixed cone. Palpus 

 moderate (about 1^), the rough scaling of its underside 

 mixed with white. Antenna with the ciliation even and 

 rather slender, about as long as the diameter of shaft. 

 Hind tibia not dilated. Head and body in general con- 

 colorous with wings. 



Fore wing shaped nearly as in latarla^ Walk., the termcn 

 scarcely even so appreciably concave in anterior half as in 

 that species ; SC^ arising from C, anastomosing with SC- ; 

 white, very closely marked with fine, largely confluent 

 (especially transversely), dark strigulation, leaving only 

 numerous very small spots of the ground-colour ; distal area 

 more solidly drab, except for a few small white spots in the 

 middle and posterh rly close to termen ; cell-dot not sharp ; 

 costal edge irregularly dotted with black, which coalesces 

 into short streaks at tlie origin of the lines; these indistinct, 

 the median diffuse ; antemedian very oblique outward from 

 one-fifth costa, acutely bent in cell, then slightly sinuous ; 

 median from beyond two-fifths, strongly excurved beyond 

 cell and strongly inbent at fold ; postmedian oblique out- 

 ward to R^, this pait blackened and almost meeting a
