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

 Calleida, excepting the ligula which in this ease is obtusely 

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

 at the apex, and the thorax, which is not as in Calleida longer 

 than broad, but the reverse. From Cymindis 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. 

 palpi, and the deeply bilobed fourth tarsal joint. However, 

 if Lacordaire's diagnoses are exact, I feel justified in sepa- 

 rating Anchista from all these genera, The name " Anchista "
