the articulations of the legs and the tarsi ferruginous. Abdomen 
deeply constricted between the first and second segment, the apex 
rufo-testaceous; the node of the peduncle incrassate, subquadrate, 
rather widest behind; the entire insect is sprinkled with pale hairs, 
which are most dense on the abdomen, particularly at its apex.
