Segment 2 has lateral bands of black meeting a line black 

 apical ring. These bands enclose the blue of the dorsum and are 

 widened suddenly towards the hinder end of the segment so as 

 nearly to cut off a small circular area of the blue from the rest of the 

 blue colour. 



vSegments 3-6 have a very fine apical ring of black and apical 

 lateral triangles, with their bases resting on the apical ring. These 

 triangles are progressively longer from 3, where the}^ occupy 

 about one-sixth of the length of the segment to 6, where they 

 occupy very nearly one-half. Segment 7 has the blue colouring 

 so encroached on by the black lateral triangles that the blue is 

 reduced to a basal ring from which a blue line runs black along 

 the mid-dorsal carina. In 8 only the carina is left blue, and g is 

 entirely black save for indication of a fine blue line at the base of 

 the carina. 10 is blue, its marginal denticulations black. 



Legs black anteriorly, greenish-brown posteriorly ; tarsi and 

 spines black. 



Anal appendages : Upper pair about equal in length to 

 segment 9 of abdomen ; curved genth' towards each other but at 

 the apices curved outwards again, and rather acutely pointed. 

 Each has at the end of its basal third a small internal blunt 

 projection, and at about the junction of the middle and distal 

 thirds a sharply pointed, backwardly directed spur. Lower pair 

 one-quarter length of upper pair or less, bluntly conical, with 

 rounded apices. (vSee pi. V, fig. 8.)

9 Head, prothorax and synthorax with colour pattern identi- 

 cal with that of male, but the blue is replaced by a yellowish- 

 green ground colour. 



Abdomen : Segments 1-9 bronze-black above, greenish-white 

 at the sides. Segment i has a median dorsal, squarish mark of 

 light blue , 2 has a narrow median line of the same colour running 

 along the dorsal carina, not quite attaining either end of the 

 segment. Segments 3-7 have each of them a basal ring of blue 

 immediately behind the basal tnargin of the segment, which 

 is fairly ringed with black. The blue ring on 3 is very 

 narrow, scarcely wider than the marginal ring of black. In the 

 mid-dorsal line this blue ring is continuous with a very narrow 

 blue line which runs along on either side of the mid-dorsal carina, 

 which itself is exceedingly finely marked with black. On 4-6 the 

 blue ring is progressively wider, in 6 it occupies the anterior fifth 

 of the segment, and in each case it gives off a short median 

 projection backwards, and is divided by the black blue of the mid- 

 dorsal carina. In segment 7 the ring is rather of a bluish green 

 colour, and it is narrower, equal only to about one-third of the 

 width of that on segment 6.
