494 ANALYSIS. 



live number of tibial calcaria in various insects. This he 

 conceived of sufficient importance to entitle Scarahteus 

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

 Oliv., 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 Phariai 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. jEscidapius 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 Scarabmis of the first part of this work, which 

 proves to be only ati/pus forma or subgenus.
