vein, three on the subbasal olivaceous line (the first being 

 costal) , and three, of which the middle one is large and repre- 

 sents the reniform spot, on the second olivaceous line : secon- 

 daries with a dark olivaceous white-pupilled spot at the end 

 of the cell. Under surface smoky grey ; all the wings with 

 a large black spot at the end of the discoidal cell, a very 

 indistinct angular dusky line just beyond the middle, a broad 

 dusky area occupying the external third, a spot on outer 

 margin, and an irregular external border (with which this 

 spot is confluent) snow-white : primaries with a large, diffused, 

 subapical, black patch : secondaries with a smaller and less 

 distinctly black subapical nebula. Expanse of wings 49 

 millim.

6. AgatMa jo'isinaj sp. n. 



Nearest to A. hemithearia ; wings bright pea-green, 

 banded with reddish coffee-brown and plum- colour, these 

 bands traversed by dentate-sinuate, silvery lines and inter- 

 rupted by spots nearly as in that species ; it differs as 

 follows : — all the bands much redder, the external belt or 

 border of primaries narrowed behind almost as much as in 

 A. discriminata ; the subapical green patch abruptly nar- 

 rowed at the back of the first spot of the subapical series and 

 extended outwards to the margin ; the third spot large, and 

 all three confluent^ as in A. discriminata ; fourth spot silvery, 

 large, but not confluent with the others ; fifth and sixth spots 

 small, green, placed obliquely ; a bisinuate inner stripe, three 

 marginal spots, and the veins at apex distinctly silvery ; costal 

 border much broader than in either of the above-mentioned 

 species and silvery ; the band crossing the wing before the 

 middle also broader and much more angular ; external area 

 of secondaries formed and ornamented as in A. discriminata^ 

 but nearly as broad (excepting towards anal angle) as in A. 

 hemithearia ; front of head whitish, with a reddish-brown 

 anterior transverse band and plum-coloured lines round the 

 bases of the antennae, the latter ferruginous internally, whitish 

 externally ; vertex of head and thorax pea-green ; tegulee 

 with reddish-brown margins and long brownish terminal 

 hairs ; abdomen reddish brown, with white sides and pale 

 dorsal spots, two of which (on the basal half) are pea-green.
