The characteristics of this new genus, are those of the g. 

 Calleida excepting the ligula which in this case is obtusely 

 acuminated, the last joint of the maxill. palpi which is obtuse

 than broad, but the reverse. From Cyminclis it would differ 

 principally in the deeply bilobed fourth tarsal joint, and in 

 some other minor points, but it is difficult to say what the 

 true characteristics of this genus are, if even Lacordaire 

 uses the particle "ou" not less than five times in the diag- 

 nosis he gives of it in his g. d. Col. It would also appear to 

 be allied to Plochionus, differing from this g., however, in 

 the obtuse extremity of the terminal joint of the maxill
