This genus has little affinity with any other of this tribe : the 

 species of it, unless closely examined, would be set aside as be- 

 longing to Calosoma or Carabus. They are however heteromerous, 

 and belong to the Tenebrionidis. I know only three species, the 

 two here described, and the other Calosoma porculatum of Fabri- 

 cius. They are all New Holland insects.
