280 Mr. IT. Campion on neiv 



hyaline, witli black veins. Arculus a little distal to the 

 second antenodal. A* arising sliarjitly proximal to the 

 cubito-anal cross-vein. 11-12 postnodals in fore wings and 

 10 in hind wings. Pterostiguia greenish brown, bounded by 

 black nervures. Dorsum and sides of entire abdomen light 

 red, a little darker on the terminal segments; under surface 

 pinky yellow. Excision in apical margin of segment 10 

 wide, U-shaped rather than V-shaped, rather shallow. Anal 

 appendages reddish ; the upper ones somewhat shorter than 

 the lower, stout, curved inwards and downwards; the lower 

 appendages shorter than segment 10, broad laterally, curving 

 gently upwards and backwards, and terminating in a rather 

 long acute point above and a shorter blunter point below. 



The antehumeral stripe of golden yellow, when present, 

 varies a good deal in width in different individuals, and may 

 be developed unequally on the two sides of the dorsal crest 

 in the same specimen. Sometimes it is absent altogether, 

 and the dorsum of the thorax may be of a more or less 

 unicolorous brownish tint. 



There is also a considerable amount of variation in the 

 relation of the arculus to the second antenodal, Tiiis is the 

 case even in the different wings of the same individual ; but 

 in the fore wings the arculus shows a greater tendency to 

 migrate outwards than it does in the hind wings, where the 

 coincidence with the second antenodal is occasionally exact. 



Similarly, the point of separation of A* is far from being- 

 constant. Rarely, in hind wings, it coincides exactly with 

 the cubito-anal cross- vein, but more commonly the longi- 

 tudinal vein arises some little distance before the level of the 

 cross-vein. 



$ (allotype). — Length of abdomen to apex of segment 5 

 16 mm. (remaining segments lost) ; length of hind wing 

 18 mm. 



Mouth-parts and head coloured as in holotype. Prothorax 

 dark brown. Dorsum of thorax greenish gold, with a narrow 

 stripe of dark green on the mid-dorsal crest, and a similar 

 stripe on each humeral suture; rest of thorax as in holotype 

 Legs as in holotype. Wings as in holotype, except that the 

 ai-culus coincides with the second antenodal in all wings. 

 11 postnodals in fore wings and 10-11 in hind wings. 

 Abdomen to end of segment 5 yellowish brown.
