new African Ourculionidae. 9 



seventh free ; the first joint of the club as long as the 

 rest together. Prothorax as long as broad, very shallowly 

 bisinuate at the base, and with a very sliglit post-ocular lobe. 

 Scutellum large, oblong, and transverse. Elytra elongate, 

 subcylindrical, with ten stria?, separately rounded at the 

 apex and leaving the sloping pygidium exposed ; the 

 shoulders prominent. Leys moderately long ; the femora 

 not toothed and but little dilated, the posterior pairs almost 

 linear and not furrowed beneath ; the tibiie strongly bent 

 neat' the base, otherwise straight, not furrowed, and nmcro- 

 nate at the apex ; the tarsal claws rather small and connate 

 at the base. Sternum : the prosternum (and still more the 

 mesosternum) well below the level of the metasternum, not 

 furrowed in front of the coxa? ; the front and mid coxa? 

 equally separated, the interspace being narrow, not broader 

 than the front tibia? ; the mesosternum with the side-pieces 

 sharply differentiated; the metasternum elongate, the length 

 between the coxa3 nearly twice as long as the mid coxa?, the 

 episternum correspondingly long and comparatively narrow. 

 Venter with the intercoxal piece rounded and comparatively 

 narrow, not broader than the hind coxa; the length of 

 segment 1 behind the coxa slightly greater than that of 2, 

 the suture between them obliterated in the middle, seg- 

 ment 2 as long as 3 + 4, the hind margins of all three almost 

 straight and only slightly angulate at the sides; the tergites 

 strongly chitinized and coarsely punctate. 



Type, Cylindrobaris omata, sp. n. 



The large size and elongate cylindrical shape of this 

 insect give it an aspect which is hardly suggestive of a 

 Bar id, the form being very similar to that of the Calandrid 

 genus Cyrtorrhinugj Lae. The close approximation of the 

 mid coxae, the tapering rostrum, and the almost straight 

 margins of the intermediate ventral segments are all some- 

 what unusual characters among the true Barides, to which 

 the genus belongs. 



Cylindrobaris omata, sp. n. 



General colour black or brownish black, with the head, 

 rostrum, antenna?, legs, apex of venter, and the last four or 

 five abdominal tergites red-brown; occasionally the whole 

 insect is red-brown. The body is decorated with the 

 following markings, formed of dense overlapping lemon- 

 yellow scales: — the whole of the scutellum; a trans\ 

 patch near the base of the elytra between stria> 2 and 5, 

 another similar one a little behind it between striae G and y,
