 largely reticulated, ending in the top of the black part in 

 elongated area:, which are rounded below ; the lower part 

 is smooth. Pleurae smooth and shining ; the basal keel 

 on the propleurre rough, irregular ; the lower half thickly 

 covered with white hair. Legs black, thickl}- covered
