Tlie Odomda or Dragoyifies of Soufh Africa. 426 



aiite-al.ar sinus. Sides light yellow ; the usual bands deep black and 

 broadly confluent in longitudinal direction. Abdomen comparatively 

 narrow, almost cylindrical; black with light yellow markings; lateral 

 and dorsal bands interrupted by transverse black carinae on segments 

 1-3 ; lateral stripes almost for full length of segments 4-7, nearer to 

 mid-dorsal than to lateral carinae; antero-lateral spots on segment 8. 

 Wings hyaline, venation black; vestige of basal light yellow spot on 

 hind wings ; yellow cloud between t, nodus and anal margin similar to 

 male, but lighter in colour. Pterostigma long, not distinctly widened, 

 dark ferruginous, faint indication of lighter line at anal margin. Anq

Frons yellow, at base with broad black, slightly metallic blue band. 

 Otherwise similar to corresponding male. (From older description, not 

 compared for present table.) Ahd. 27, hdif. 29, pt. < 3 mm. T. anreola.

This common species is known from the Afi'ican continent through- 

 out between Algeria and Natal, from Syria, the Canary Islands, 

 Socotra and the Comoro Islands. 



There is considerable variation in extent of the golden-yellow basal 

 spot, not strictly depending on geographical distribution ; but generally 

 speaking it may be stated that forms with very large patch are more 

 restricted to the inter-tropical parts of the continent, those with 

 smaller patches being prevalent in the northern aud southern limits of 

 distribution, though even there specimens with large patches are not 

 altogether absent. Various names have been proposed for these 

 varieties, but it seems much better to relegate those names to 

 svnonomv.
