Genus — Bradinopyga. 



Fig. 41. — Wings showing neuration of Bradinopyga geminata. 



Head : eyes broadly contiguous; forehead narrow and sloping ; suture mode- 

 rately deep ; vesicle rounded or with two small points. 



Prothorax ; posterior lobe small, rounded procumbent. 



Thorax robust. 



Legs moderately short and slim. Hind femora Avith numerous, closely- 

 set, short spines ; mid-femora with a row of gradually lengthening spines ; 

 tibial spines numerous, about 12 pairs. The leg armature about the same in 

 the sexes. 



Abdomen at the base, a littledorso-ventrally dilated, very sHghtly constricted 

 at the 3rd segment, sides nearly parallel and tapermg very gradually to the end. 

 A more or less distinct, transverse ridge on the dorsum of the 4th segment. 



Wings long and moderately broad ; trigone in the forewing one or two eells 

 distal to the line of the trigone in the hind ; sectors of the arc in both w^ngs 

 with a long fusion ; arc between the 1st and 2nd antenodal nervures ; 8th 

 nervure in the hindwing arising from the anal angle of trigone ; antenodal 

 nervures 10| to 12|, the final complete ; trigone in the hindwing at the arc 

 or a little proximal ; 1 cubital nervure to aU wings ; no supplementary ner- 

 vures to the bridge ; trigone in the forewing traversed occasionally twice ; 

 trigone in the hind entire or traversed, its distal side concave ; all hypertri- 

 gones entire ; 4th nervure markedly undulating ; discoidal field generally with 

 4 rows of cells, occasionally a more or less lengthy space with 3 rows of cells ; 

 strongly dilated at the termen ; anal field in the hindwing broad ; loop long 

 and broad and with divided cells at the outer angle ; cells between the inner 

 border of the loop and the base of wing arranged in transverse rows. 



Stigma of medium size. Membrane large. 



Only one species which is readily distinguished by its stigma, which is black- 

 ish and white at both ends. Trithemis pallida has a somewhat similar coloured 

 stigma but the number of antenodal nervures in this insect do not average more 

 than 8J, whereas Bradinopyga has not less than lOJ. 



47. Bradinopyga geminata. 



Libellula geminata, Rambur, 1842. 



Expanse 70 mm. Length 44 mm. 

 Head : eyes browli above, opalescent or purplish at the sides and beneath ; 

 vesicle black ; occiput brow>n ; front, epistome, labirm and labrum brown 

 mottled obscurely with white and black, anastomosing streaks.
