 iiotum sube<iual on the prozona, expanding posteriorly on themetaz(»na, 

 darker above than on the sides, the lateral lobes with a broad, broken, 

 and irregular, piceous, postoeular band confined to the prozona, the 

 disk nearly i»]aue but feebly convex, passing into the vertical lobes by a 

 (listinctlyangulated but rounded shoulder nearly forming lateral carinae 

 uu the metazona; median carina distinct on the metazona. subobsolete 

 and equal on tlie prozona; front margin truncate, hind margin obtusau- 

 giilate. the angle well rounued : lU'ozona feebly transverse in both sexes,
