contracted, end of 3 to 10 eyliudrical, slender. Earlets of second

 very good condition.) Segment 1 light ochreous, greyish olivaceous 

 iu posterior half of 'dorsum ; 2 light ochreous at sides, olivaceous in 

 anterior, light blue (probably a very distinct mark in the living 

 insect) in posterior half of dorsum ; 3-8 dull ferruginous, with a 

 black line at transverse carina, and behind the carina a blackish-brown 

 dorsolateral sjjot, which increases gradually from the third to the 

 eighth segment, and includes on each side a terminal, roughly triangular 

 dull ochreous spot ; 9-10 ochreous with mid-dorsal blackish band. 

 Superior appendages deep black, inferior light yellow ; superior 

 lanceolate, not excised internally, with a not very dense row of fine 

 black ciliae at internal margin, produced into a slender and very 

 acute point ; inferior one triangular, obtuse, between one-third and 

 oiie-half the length of the superior, not iu good condition for a 

 drawing, agreeing well with R. Martin's figure. 



Wings hyaline, reticulation in costal and basal part greyish 

 ochreous ; costa light ochreous. Brown, fumose basal mark along 

 the veins in costal, sub-costal and cubito-anal sjiace to first cross-vein.

9 . Very similar to male. No blue on second abdominal segment ; 

 dark dorsal spots of following segments smaller and not so deep iu 

 colcur. Ninth segment moderate (3 mm.) ; ovipositor similar in 

 structure, but much less developed in dimensions than iu G. villosa. 



AESCHNA (Faljricius, 1775, emend.). 

 A large cosmopolitan genus, not fully homogeneous, most species 

 belonging to the temperate regions of the Northern hemisphere. 

 African species are not numerous. Of our two sjaecies one (iniiiuscula) 

 is of uncertain affinities ; the other [suhpupillata) is representative of a 

 group otherwise known from tropical East Africa. 



Larger species. On superior surface of frons an oculate niarlc ; black 

 median basal spot surrounded by light yellow and then by bluish grey. 

 Genital lobe in second segment of male much produced A. subpupillata. 

 Smaller species. On superior surface of frons a T-spot with broadly 

 triangular base and broad, crescentic horizontal )iart along anterior 

 frontal ridge. Genital lobe of male not produced . . A. mluKscida. 



Aeschna subpupillata (MacLachlan, 1895).
