base is much more than twice as long as the distance 
between its anterior angles, and the distinct two-jointed 
and two-clawed anterior tarsi. The elytra are generally 
undeveloped and appear only as two transverse scales 
about twice as long as the scutellum, when developed 
they have a distinct membrane; ¢ with the last abdominal 
segment produced and almost covering the genital seg-
