tive number of tibial calcaria in various insects. This he 

 conceived of sufficient importance to entitle Scarabaus 

 H. E., Gymnophurus Illig., together with S. Msculapius 

 Oliv.j to the rank of a family, because they all possess two 

 calcaria less than other Coprophagous insects. To me the 

 observation appeared to afford the generic character for 

 which I had hitherto been fruitlessly seeking — a character 

 by which it was possible to group these insects together in 

 much the same manner as the Phanai had already been as- 

 sembled, on account of all wanting ungues to their tarsi. 

 The arrival also in England of an extraordinary insect, 

 forming a type intermediate between the Scarabaus Sacer 

 and S. Msculapius of Olivier, enabled me to descry not 

 only the limits of the genus, but its series of affinity such 

 as I now present it to the Entomologist, instead of the 

 genus Scarabaus of the first part of this work, which 

 proves to be only a typus forma or subgenus.
