In this genus the mandibles are bifid at the tip. 
Gopidita agrees with Oxacis (which has the mandibles 
pointed or entire at the tip) in having the eyes large, 
more or less oblong or oblique, and coarsely granulated ; 
the thorax cordate or oblong cordate ; the apical joint of 
the maxillary palpi elongate, cultriform or elongate- 
triangular; and the apical joint of the antsnnee con- 
stricted about the middle. Sessinia^ and Ananca were 
not characterized by their authors ; numerous species 
belonging to different genera have been assigned to 
them by various writers. 
* Sessinia has recently been characterized by Semen ow [Horae 
Ent. Ross., xxviii., pp. 454, 455, nota (1894)], who gives Nacerdes 
livida, F., as the type, and states that it has the mandibles acute 
and entire at the tip ; N. livida is certainly not separable from 
Oxacis, Lec.
