head and thorax are somewhat reduced in extent, the metepisternal 

 stripes imcomplete or interrupted ; their colour dark brassy or coppery 

 with a slight greenish lustre. Wings almost uniformly yellowish, the 

 colour duller than in the male and the bluish iridescence far less 

 brilliant.

1 B. FAMILY AGRIONIDAE. 



1. Pterostiguia comparatively large, covering two or more cells. Supple- 



mentary short sectors between the distal ends of some or most of the 

 regular veins. Quadrilateral with the anal-distal angle very acute. 

 (Plate VI, fig. 8, Plate VII, figs. 1, 2, 3, 4, 5, 6.) Spines of femora and 

 tibiae long. Superior appendages of males forcipate . .2. 



Pterostigma small, covering one cell or less, only exceptionally more. 

 No supplementary short sectors. (Plate VII, figs. 7, 8, '.), 10, Plate VIII, 

 fig. 1). Superior appendages of males not forcipate . . .3.

Origin of A* at Cuq. (Plate VI, fig. S) . . Lesles. 



Origin of M'3 and bridge of Rs in the nodal region, pre.lmiii.intly 71/3 at 

 the subnodus and bridge of Rs one or two cells dtstally. Origin of .4* 

 distal to Cuq. (Plate VII, figs. 1, 2, 3, 4, 5, 6) . . Chlorolestes.

Quadrilateral oblique, the anal-distal angle acute. (Plate VIII, fig. I.) 

 Spines of tibiae short . . . 7. 



4. Origin of A* at Cuq or very little proximal, not more than the length of 



Cuq. (Plate VII, figs. 7, 8, 9) ... .5. 



Origin of A* very considerably proximal to Cuq, several times the 

 length of Cuq. Quadrilateral slightly more oblique than (5) and shorter, 

 approaching the form of (7). Rs at subnodns, M'3 proximal by one cell. 

 (Plate VII, fig. 10) . . Metacnemis.

 Cu 2 incomplete or absent, exceeding the level of nodus at most by one 

 cell. (Plate VII, figs. 8, 9) . . 6. 



6. C'(t 2 exceeding the distal side of quadrilateral by one cell iu front wing, 



by two cells in hind wing. 



Origin of A* at Cuq, M'3 at subnodus, Rs one or two cells distal. 



(Plate VII, fig. 8.) Abdomen excessively long and slender. 



Chlorocnemis. 



Cn 2 not developed ; ^4* stopping at the vein which continues the distal 

 side of quadrilateral Origin of A* slightly proximal to Ctiq. Rs at 

 subnodus, M'3 proximal by one cell. (Plate VIII, fig. 9.) Abdomen 

 moderately long and slender ..... . Disparoneura.
