nrculiis (proxinml to second ant«^notlal) and in tlio confi2;nra- 

 tion of the eyes, tlie poslorior lobe of the prothoiax, and the 

 genital seoruicnts in female. 



'lV|)e of venation between Crocolhemis and Bradinopi/fja ; 

 differinp^ from both by configuration of eyes and of posterior 

 lobe of prothorax. 



In regard to eyes and ])rothora\- nearest to Rhodothemis. 

 Spines of legs not so markedly differentiated as in Rliodo- 

 themis. More important differences from that genus : 

 (1) discoidal area in front wing with 3 rows of cells to level 

 of nodus, (2) Cu, in hind wing at anal angle of t., (3) 2 roAvs 

 lls.-Kspl., (4) 4-5 rows between A3 and wing's edge in hind, 

 wing, (5) last Anq. in hind wing incomplete, apparently an 

 almost regular and therefore veiy curious feature. 



Cyanotliemis will find its place in our systematic arrange- 

 ment of Libellulinte immediately preceding Rhodothemis. 



Head moderate ; eyes meeting scarcely more than in a 

 point : occipital triangle very large. Frons very prominent, 

 rounded, without anterior ridge, and not flattened anteriorly ; 

 furrow moderate. Vertex broadly convex, very slightly 

 einarginate. 



Posterior lobe of prothorax large, erect, divided into two 

 rounded lobes, ciliate. Thorax robust. Legs comparatively 

 short, robust. Male with third femora armed in proximal 

 Iwo-thirds with about 10 moderately robust spines, increasing 

 in length very gradually, 3-4- longer s))ines at end ; second 

 femora with about 7 small, gradually lengthening and 2 

 terminal long spines. Spines of tibia3 long and robust, 8—9 

 on third tibias. Teeth of tarsal claws robust, in distal third. 



Abdomen rather short, relatively broad, depressed ; mode- 

 rately widened at base dorso-ventrally, very gradually nar- 

 rowed to end. No distinct transverse carina on fourth segment. 

 Genitalia of second segment small, tlie hamule with regular 

 external branch. For genital segments of female see under 

 the species. 



Wings long, reticulation serrate, t. in front wing on a 

 level with t. in hind wing. Sectors of arculus with a long- 

 common stalk in both wings. Arculus between Anq. 1 and 2. 

 Cuj in hind wing at anal angle of t. Anq. 12^-14^, last 

 Anq. incomplete in hind wing as well. Pioximal side of t. 

 in hind wing at arculus. 1 Cuq.in all wings ; noBqs. t, in 

 front wing narrow, crossed, t. in hind wing crossed ; lit. 

 free ; ti. in front wing 3-celled. M2 feebly double-curved. 

 2 rows Rs.-llspl. Cui in front wing strongly convex ; 

 discoidal area considerably widened to end ; 3 rows to level 

 of nodus. 1 row Mj-.Mspl. Anal area of hind wing broad.
