1922.] F. C. Frasek : Odonata from the Nil%i>is 7 



3 with a very narrow and obscure basal annule, segments 4 to 7 

 with broader annules, increasing in breadth from the 4U1 to the 

 7th; 8th segment turquoise blue with the apical border more or 

 less narrowly bordered with black, this colour being continued 

 very narrowly along the dorsal carina and tapering gradually 

 towards the basal end of the segment; segments 9 and 10 all 

 black. The relative size of the segments is much the same as in 

 the former species but 8 is only very slightly longer than 9. 



Anal appendages much the same as in the last species but 

 the spine at the base is more on the outer side and much stouter, 

 the chelate ends are broader and the broader arm bifid at its 

 extremity. 



Female. Abdomen 39 rritn. Hindwing 26 mm. 



Very similar to the male but of much stouter build and with 

 a shorter abdomen. 



Head. Eyes deep bottle-green above, paler green beneath, 

 these two shades of green separated by a thick, equatorial line 

 of black. Rest of head as for male but the blue on labrum and 

 lower epistome is of a deeper shade. 



Prothorax blackish above, dirty white at the sides; the 

 posterior lobe with lateral prolongations shaped as two projecting 

 points. 



Thorax as for male but blue markings of a deeper shade. 



Wings hyaline; postnodal nervures to forewing 16, in the 

 hind 15 ; stigma a cherry red ; arc distal to the 2nd antenodal 

 nervure. 



Abdomen black with white or blue markings as follows : — 

 1st segment with a blue lateral spot, segment 2 has a bluish 

 lateral basal marking prolonged along the ventro-latera 1 border, 

 segment 3 has the middle two-thirds or three- fifths of its ventro- 

 lateral border a pale whitish brown, segment 4 has very obscure 

 basal and ventro-lateral markings, segment 5 has a well-marked 

 basal white annule, segment 6 obscure basal and ventro-lateral 

 markings, segment 7 has a broad basal annule bluish in colour, 

 occupying about one-third of its length, the remaining segments 

 entirely black. 



Habits. Found in similar situations to the last but more 

 retiring and never coming out into the open. The four specimens 

 taken were in the deepest jungle clinging to maiden-hair fern 

 sprouting from crevices in the rocks The insect is readily distin- 

 guished from others by its red stigma and by the equality in size 

 of segments 8 and 9. 



Type in my own collection, paratypes in British and Indian 

 Museums.
