 cylindrical, flattened and slightly canaliculate underneath; hind 

 femora reaching to the tip of the elytra. Tarsi narrow, third 

 joint nmch shorter than first or second, not very deeply emargi-

This genus seems to resemble most Ancyloprotus Wliite, 

 l)ut ma}' be readily distinguished by the longer legs, wider elytral 

 ('l)i|)leur( s, larger scutellum, separated antennal tubercles, and by 

 the })()sition of the lateral thoracic spines and several other cha- 

 racters including the obtusely rounded inlercoxal process of the 

 abdomen in the female.
