brown. Occipital triangle black with yellowish centre and pos- 

 terior margin. 



Thorax greenish-brown, without black markings, save along 

 the suture lines of the coxae ; base of femora brown. 



Abdomen. — Segment i, and the inter-segmental memlirane be- 

 tween I and 2 buff-yellow, posterior margin of i narrowly edged 

 with brown. Segment 2 turquoise blue above. The rest of the abdo- 

 men is in general brownish-black dorsally, rather paler brown ven- 

 trally. Segment 2 has its terminal transverse carinae and jugum 

 black, the blue colour of the dorsum passes laterally to a silvery 

 Yellow. Segment 3 has its prejugal division turquoise-blue, passing 

 to silvery yellow ventrally, mid-dorsally a longitudinal black line, 

 widening distally, is continuous with the black o! the post-jugal part 

 which carries on either side two large, rounded yellow spots. Seg- 

 ments 4 — 8 have each a pair of bluish-yellow spots on the prejugal 

 division, almost obsolete on 8, and two rounded yellow spots in the 

 supra-carinal area of the post-jugal division on either side. On 

 7 — 8 these supra-carinal spots coalesce to form a continuous yellow 

 band. In addition 4 — 8 have a round lemon-yellow inter-carinal 

 spot immediately behind the jugum. 



Lastly, g — to have each a pair of large yellow lateral spots : 

 the homologues of the supra-carinal spots of the preceding seg- 

 ments, on 9 these spots are triangular with the apex directed 

 forward, on 10 they are rounded. 



The anal appendages are dark-brown, the upper pair have a 

 blunt triangular projection at the middle of their inner margin. 



Length of hinder-wing 50 mm., of abdomen 51 mm., anal 

 appendages 6 mm. 



.Series B. 



The single male of this series is from Calcutta. It is almost 

 exactly intermediate between the males of series A and series C. 

 6187/20. 



In the following account the characters in which it differs 

 from series A are mainly noted ; where no remark is made, it may 

 be assumed that the specimen is practically identical with the 

 males of A. 



& (spirit specimen from Calcutta). 



Wings. — The yellow tinge of the hinder- wing less extensive, 

 extending onlj; to the level of the nodus. Basal white mark on 

 membranule very small. 



Head. — A small triangular area in front of the vertex is brown. 



Abdomen. — The black of the dorsal surfaces is much more 

 intense than in A. The post-jugal spots of segment 3 and the 

 supra-carinal spots of 4 — 8 are greenish-yellow in colour, rather 

 rectangular in shape, and much smaller than those of A. The 

 supra-carinal spots on 7 — 8 do not coalesce to form a band and the 

 anterior spot on each of these segments is obsolete. The spot on q 

 is small, representing the posterior supra-carinal spot only ; and 10 

 is without markings. There are no inter-carinal spots. 



Anal appendages as in A.
