INDIAN DRAGON FLIES. 495 



Wings hyaline, tlie bases slightly saffronated as far out as the trigones : 

 reticulation close : node slightly proximal to the middle of the wing : trigones 

 in Une with one another, that of the hindwing slightly distal to the arc,°both 

 entu-e, that of forewdng broad, its costal side about equal to half of its proximal 

 and its distal side angulated outwards : subtrigone of forewing with 3 cells, 

 (in one of the tw^o specimens the basal cell of the subtrigones is traversed by a 

 curved nervure) : no supplementary ner\T,ires to the bridge : only 1 cubital 

 nervure to all the wings : discoidal field dilated strongly at the terinen, begins 

 with two rows of cells for 4 cells outward only, 7 antenodal ncr\T.u-es, the last 

 complete: stigma long (4mm.), that of the hindwing distinctly larger than 

 that of forewing, yellowish : 8th nervure arising from the anal angle of the 

 trigone in the hindwing : only 1 row of cells between Rs and Rspl (0 and 5a) : 

 Ms (Mspl.) weU formed in the forewing only : sectors of arc long in the forewing, 

 lying between the 1st and 2nd antenodals, of greater length in the hindwing. 



The large size of this insect at once distmguishes it from all other Indian 

 species of the genus as does also the unicolourous thorax. The general facies 

 resembles an Orthetrum or a Crocolhemis but the 2 i-ows of cells in the discoidal 

 field will readily distinguish it from both of these, whilst the dilated field will 

 also distinguish it from a Sympetrum for which it might be mistaken.
