Segment 3 bluish at its base, black for the apical half or two-thirds and with 
an apical and sometimes with a medial bluish spot on either side ; segments 
4 to 8 black spotted with bluish grey or dirty blue, varying in almost every 
specimen—usually however there is an oval, apical spot and a medial and basal 
small spot on each side which are never connected up ; the 9th and 10th seg- 
ments are black, the former with a single bluish spot and the latter either un- 
spotted or with its apex and sides greenish yellow and the borders finely brown. 
Anal superior appendages differ somewhat from those of Anaa gutiatus, they 
are decidedly broader, the middle third projecting markedly inward ; the in- 
ferior appendage is square, greyish and with borders diffusely black. 
Female very similar to the male and differing as follows :—- 
Eyes greenish grey in the living state ; abdomen more tumid at the base 
and not constricted at the third segment as in the male. The blue on the 2nd 
segment is only evidenced by a small, diffuse area on the dorsum and the sides 
are silvery yellow ; segment 3 has no trace of blue colouring and the base is 
greenish yellow. 
The spots on the abdomen are greenish yellow in colour, larger and more 
extcnsive and there are additional basal, infero-lateral spots on segments 4 
to 5 and sometimes also on 6. 
Hab.—N. E. Himalayas, Assam, Upper Burma, Missouri and Dehra Dun. 
Anax parthenope tacchus appears to replace Anax gultatus in the North of India 
and bridges the gap between the latter species and Anax parthenope julius. 
It breeds in tanks and oviposits in shallow water.
