a protuberance on the foiorth tarsusj and the scutal ornamentation 

 is somewhat different from that usually described for this species 

 (compare with Theiler Y)U5k description and illustration). However, 

 Theiler (correspondence), who has had more experience with this 



genus in Africa than anyone else, writes: '"A. halli to me, 



is but an extreme variation of A. exornatum, being as far as I can 

 see, the exact replica of A. arcanum Karsch, 1879". In view of 

 this opinion and with Dr. Theiler's permission, A. halli Tendeiro, 

 1950, has been synonymized under A. exornatum (Koch, IS^A) (Hooc- 

 straal 195/3). 



IDENTIFICATION 



Theiler (19^5A) described and illustrated the immature stages 

 and redescribed the adult stages of A. exornatum . 



Males and females are easily identified by generic characters 

 plus the presence of scutal ornamentation consisting of green or 

 coppery markings on the shiny dark brown surface. Other characters 

 are mentioned in notes under the key to this genus.
