Origin of A* distal to the level of proximal side of 9. One row of cells in 

 field Rs — M3. Pterostigraa less than three times as long as broad. 

 Medial edge of superior appendages of male smooth. Occiput blackish. 

 Inferior appendages of male bifid at tips 3. 



2. Pterostigma long, nearly four times as long as broad. Two rows of cells in 



distal half of field Rs — M3. Medial edge of superior appendages in 

 male smooth. Occiput yellow. Largest species of genus . conspicua. 

 Pterostigma less than three times as long as broad. One row of cells in 

 field iJs — J/3 throughout. On medial edge of superior appendages in 

 male a sub-basal tooth and a sub-apical lobe. Occiput metallic green. 

 Smaller species ......... Pcringueyi. 



3. Ciiq distal to the level of first Anq. Pterostigma mostly two coloured, black 



at the proximal, yellow or reddisli brown at the distal end (almost 

 wholly black in some very mature sjjecimens) ..... 4. 

 Cuq at the level of first Anq or slightly pro.ximal. Pterostigma uniformly 

 coloured, light yellowish or reddish brown. Smallest species of genus 



itmbrata. 



4. Abdomen very long, its metallic colour dull. On the humeral suture a broad 



yellowish or olivaceous band. On the second lateral suture at most 

 some indistinct traces of darker colour. Metasterna with dark mark- 

 ings 5. 



Abdomen much shorter, its metallic colour brilliant green. Anterior to 

 the humeral suture a narrow yellowish band not entirely to the dorsal 

 end. A sharj)ly defined blackish band at the second lateral suture. 

 Metasterna with a very narrow dark line on the median suture only. 



fasciata. 



5. Wings of adult male whitish pruinose from 9 to about the proximal third 



of the distance between nodus and pterostigma, dark brown on the second 

 third of this distance or slightly more on front wing, for two to three 

 cells more in hind wing ....... tessellata. 



Wings of all specimens hyaline, at most a very narrow brownish border 

 of the tips. Otherwise very similar to preceding species . longicauda. 



Chlorolestes conspicua (Sclys, 1862).

 coloured). Labium whitish yellow, occiput ochreous, blackish in the 

 upper fourth. Labruni shining; black. Auteclypeus dull yellow ; 

 geuae and base of mandibles bright yellow. Dorsal surface of head 

 deep reddish brown, blackish in the ocellar region, brilliant metallic 

 green in a narrow band on each side along the eye. Prothorax dark 

 reddish brown, with a round orange spot on each side. Thoracic 

 dorsum vei\v deep brown, almost black, a narrow orange baud near 

 the humeral suture, distant from the suture slightly less than its own
