Anterior coxae separated by somewhat more than half their width, the even

 similar in almost every feature, except that the beak is separated by a deep 

 sulcus and is strongly constricted near basal third or fourth in both sexes; 

 pygidium more convex. [Type A. squamiventris Chmp.].. Anisorrhamphus

 constricted apically. Body rhombic-oval, convex, distinctly but not densely 

 squamose beneath; thoracic lobe very small, the scutellum free, the elytra 

 grooved and the pygidium very small; beak slender, arcuate, with a high 

 and prominent cariniform crest at base, apparently in both sexes; femora 

 undilated, mutic, the tarsi narrow. [Type T. electa nov.] Tropidobaris 



Anterior coxae very approximate, separated by less than a fourth of their width, 

 the presternum not distinctly constricted. Body narrowly rhombiform,
