Coleopterous Sab-Family Byrsopince {CurculionidcB). 55 



deflected, their cutting edges almost perpendicular to the long axis 

 of the rostrum, without a mandibular scar; submentum with a 

 distinct projection behind the mentum; scrobes sharply curved, 

 passing obliquely much below the eye, but widely separated 

 beneath. Antenna short and stout, inserted about middle of 

 rostrum ; scape clavate, not reaching the eye ; funicle with 

 joint 1 a little longer, but scarcely broader, than 2, 3-7 very 

 short, strongly transverse and gradually widening outwardly; the 

 club shortly ovate, sharply acuminate, 4- jointed. Thokax with a 

 lateral spine, the ocular lobes strongly developed, the dorsal lobe 

 emarginate, the two processes usually curving downwards over the 

 forehead ; prosternum with a very deep channel in front of the 

 coxae, the latter contiguous and placed near the posterior margin ; 

 meso- and meta-sternum with the side-pieces fused, and the sutures 

 obsolete, the intermediate coxae entirely contiguous, the posterior coxal 

 cavities rounded outwardly and widely separated from the elytral 

 margin. Elytea ovate, with the shoulders sloping, set with 3 or 

 5 rows of tubercles and 2 large basal calluses, the lateral margins 

 strongly inflexed and regularly foveate. Abdomen with the 2nd 

 segment almost as long as 3rd and 4th together, and separated from 

 1st by a curved suture, the intercoxal process broadly truncate. 

 Legs stout, femora sublinear, tibiae straight and subcylindrical, 

 with a short internal mucro at apex ; tarsi rather long, squamose 

 and setose beneath, with the edges of the joints fringed with silky 

 golden hairs (often abraded) especially at the angles, the third joint 

 not broader than the others, deeply emarginate but not lobate, the 

 fourth joint stout and almost as long as the three basal joints ; claws 

 very long and free. 



This genus replaces Byrsops in South-East and Central Africa. 

 On the West it is known only from Angola and Damaraland, but on 

 the Eastern side it extends from 30° S. up to the Equator. The 

 species feed on low shrubs, but are largely terrestrial in their habits.
