3. Neocallis n, g. 



Closely allied to Mesocallis Mats., but differs from the latter as follows : — 

 Antennae mucli robuster, all the joints, except the first two, with oblong 

 sensoria in one row, situated crossweis, those of the 3rd joint being semiring-like 

 and occupying the outer half surface, and extending all over the whole length; 

 anterhinarial scarcely shorter than the postrhinarial, acutely pointed. Wings 

 nearly the same, but the 2nd oblique at the base somewhat nearer to the first than 

 the 3rd ; 2nd furcal originates rather nearer to the apex of the first. Abdomen 

 on the lateral sides with tubercular projections; cornicles shorter, cauda globular, 

 larger. Empodial hair at the apex rounded and clavate.
