G. amyntor, Kl. (Peters's l Reise n. Mossambique,' p. 242), 

 is from Sena : — " Am ahnlichsten ist diese der G. caffra, 

 deren v. Winthem in einem Verzeichniss caffrischer Insecten 

 erwahnt. Sie bildet den Uebergang zu der um eine Linie 

 kleineren G. orion, Dej., von Senegal. Von beiden Arten ist 

 sie unterschieden durch den oben nicht glatten, sonst durch 

 Punkte und Runzeln uneben Kopf mit dem darauf sitzenden, 

 an der hinteren Seite flachen, hockerigen, vor der Mitte 

 deutlicli zweigezalinten Horn und dem in beiden Geschlech- 

 tern starken und dichten fast iiberall punctirten Halsschild." 



It appears to me from these extracts that G. orion, Kl., is 

 more strongly punctured than C. lunaris, which is scarcely 

 the case with G. orion, Boheman; and G. amyntor, KL, is 

 still more strongly punctured, and moreover has the head 

 rugose. The species which I have identified as G. amyntor 

 we have received from South Africa and Nyassa. From 

 description I should think it possible that G. obesa } Bohem., 

 is the female of this species. 



The following notes may be of service in determining the 

 species of this group : — 



f Middle lobe of thorax, 



emarginate. J 



Elytra deeply J 

 striated. \ 



Head smooth orion, Bohem.

 tured amyntor, Kl.

but with the middle 

 pair scarcely deve-^ 

 loped and appearing 

 like one.
