Mr. J.S. Baly’s New Genera 
Thorax transversus, lateribus medio angulatis, disco trans- 
versim depresso. J¢lytra thorace paullo latiora, parallela, 
subcylindrica, confuse punctata. Pedes subelongati, robusti ; 
coxis anticis erectis, contiguis; femoribus posticis non in- 
crassatis ; tibiis omnibus apice muticis; tarsorum posticorum 
articulo basali’ duobus_ sequentibus longitudine equali; 
unguiculis muticis, basi incrassatis. Prosternum fere obso- 
letum. 
Type, Chorina (Monocesta) cincta, Clark. 
Chorina may be distinguished from Syphazia by the longer and 
rather more slender antennw and by its parallel body; from 
Monocesta (in which genus the two species have been placed by 
Mr. Clark) the simple unguiculi at once separate it; the body is 
also 
Mr. 
more parallel than in Monocesta, approaching in that respect 
Clark’s very natural genus Dircema.
