Morelet gives Guinea as the locality in his first notice; 

 Gabun in the second. It is an elongate species of peculiar 

 coloration, consisting of radiating spots of the yellowish 

 ground-color below the suture, contrasting with the chestnut- 

 brown color of the rest of the surface. It is quite solid, and, 

 as Kobelt remarks, not without a tendency towards Homorus. 

 Morelet 's figure is copied.
