The Odonata or Draywflies of South Africa. 371 



ANAX GEORGIUS (Selys, 1872). 



This species is represented by the single male type in the Brussels 

 Museum (formerly St'lysian Collection), a very old specimen, bearing 

 besides other labels of later date an old label in de Sc'lys 1 hand 

 " Vanderh. Timor r ou Natal ? ." There are under the same collector's 

 (Vauderhoffen) name other South African, but also Malaysian and 

 Japanese insects in the collection. The home of this unique specimen 

 remains thus uncertain ; if I may venture a supposition, I would 

 rather locate it in Africa than in Malaysia, since it is something of a 

 reduced edition of A. tristis, though certainly a very distinct species. 

 De Selys and R. Martin give somewhat summary descriptions. Martin 

 also a coloured figure of the entire insect and a very good figure of its 

 appendages. The following is a more detailed description of the type. 



^ (adult, rather badly discoloured, colours of living insect 

 possibly black and green as in tristis). Labium and labrum dull 

 orange. Face and frons anteriorly light green. Dorsal surface of 

 frons greenish, blackish brown at base, this colour triangularly pro- 

 jecting, narrowly fused to a black line at the anterior ridge ; this 

 black line bordered by a light bluish-grey band. Thorax badly dis- 

 coloured, probably light green in life ; latero-ventral sutures very 

 slightly lined with brown. Light blue small spot at wing bases. 

 Legs black; base of first femora ferruginous internally. 



Abdomen moderately inflated at base, much constricted in third 

 segment, very gradually dilated from end of third segment, broadest 

 at 8-9. Rather badly discoloured, markings not easily distinguished. 

 Segment 1 greenish laterally, reddish brown ou dorsum, anterior half 

 depressed, posterior half gradually rising but not above the height of 

 segment '2, the elevated part densely covered with short ferruginous 

 hair. Segment 2 greenish with three laterally incomplete, tranverse 

 blackish bauds : behind a first transverse carina which projects 

 angularly hindward in mid-dorsal line, on a second transverse carina 

 with a mid-dorsal dilatation, at posterior margin. Segment 3 black, 

 anterior half of sides whitish, this colour widened anteriorly and 

 narrowly ascending to mid-dorsal line at anterior end ; very small, 

 round, lateral dull ferruginous spots near posterior end. Segments 

 4-8 black, 011 each side two small, rounded dull ferruginous spots, 

 near anterior and near posterior end ; a third spot on segments 7-8 in 

 middle of length between a supplementary and latero-ventral carina. 

 9-10 dark reddish brown (discoloured). Supplementary lateral 

 cariuae distinct only on segments 7-9. Appendages dull ferruginous : 

 lateral margin of the superior ones almost straight, 1 lending rather 

 abruptly near the end to the obtusely rounded apex; median margin
