 the dorsal surface of the head black, with metallic reflex. 



Prothorax : above and at the sides bronze-black ; below whitish. 

 A small spine rises from the middle of the posterior margin, it is 

 hooked vertically upwards, and is about one-half the size of 

 that found in A. ivallacei. Seen from above, the lateral angles 

 of the posterior margin are produced as a very small pair of 

 outwardly directed spurs.

Abdomen : segments 1 and 2 metallic green above, brownish 

 white below. The succeeding segments are of a dull brown 

 colour, becoming progi*essively darker, their vmder surfaces paler, 



Pterostigmata black, with a very fine grey margin, which is 

 much narrower than in A . ivallacei. 1 3 antenodals in the fore wing. 



Legs white (first two pairs lost), with articulation between 

 femur and tibia black, a fine black line running along the whole 

 posterior surface of the femur. Tarsus missing. 



Anal appendages whitish, lower pair about four-fifths the length 

 of upper pair. The upper pair are curved a little downward, their 

 extremities flattened laterally and folded in on themselves. Each 

 has at its middle a rounded projection directed inwards. Lower 

 pair much as in ^. toallacei, but ending in an upturned point.

 posterior margin. The whole of the prothorax and thorax, is of
