116 MR. G. A. K. MARSHALL OX COLEOPTERA [Jan. 19, 



anterior margin slightly convex, ocular lobes almost obsolete. 

 Upper surface almost plane, closely covered with small rounded 

 tubercles, leaving a very indistinct central furrow containing a 

 short but well-marked carina ; a distinct transverse dorsal im- 

 pression just behind apex ; tvibercles bare, each with a pale 

 depressed seta, the interstices with dense brown scaling. Elytra 

 elongato-ovate, shoulders sloping, sides slightly rounded, broadest 

 about middle, the posterior declivity laterally compressed, so that 

 the space between the second intervals on each elyti-on is distinctly 

 raised, apical processes moderately long and sharp in both sexes. 

 Upper surface convex, faintly striate, the strife with indistinct 

 punctures separated by small granules ; intervals even and with 

 regular rows of granules except the first, which is smooth through- 

 out, and the lateral compressed portion of the declivity is also 

 almost free from granules ; scaling rather thin, variegated brown, 

 with the inflexed margin and a broad sutural stripe much paler ; 

 setse pale, very small and much depressed. Legs long, rather slender, 

 with sparse pale set?e ; posterior tarsi broad, the joints of about 

 the same width, 2nd and 3rd subeqvial in length, 1st a little longer. 



Cape Colony. 



Type in the British Museum. 



A striking and quite isolated species, which may be readily 

 distinguished from all its congeners by the peculiar structure of 

 the rostrum — especially in the character of the basal horn, the 

 transverse dorsal incision, and the acuminate gense.

Long. 22-25, lat. 8-10 mm. 



Head convex on vertex, forehead flattened and without fovea 

 or carina, punctuation indistinct ; anteocular furrows deep. 

 Rostrum not cut off from head by a deep dorsal incision, as long 

 as head and prothorax, strongly curved. Upper surface with a 

 stout basal tubercle, which is I'oundedly bifid at apex, broadly 

 excavate anteriorly, the edges there raised and dilated, without a 

 central carina and with shallow punctuation along the edges only ; 

 lateral svilci viniting at base, the upper ones narrow and rather 

 faint, the lower longer and deeper ; scrobes directed beneath base 

 of rostrvim ; inferior basal furrow distinct. Antennce with sparse 

 pale setae ; scape not nearly reaching eye ; the two basal joints 

 of funicle subequal. F?'othorax as long as broad, apex a little 

 narrower than base, sides rounded, broadest about middle, apical 

 margin convex, ocular lobes strongly developed. Upper surface 

 almost plane, fairly closely set with large subconical tubercles, 

 leaving a narrow central furrow containing a short but distinct 

 carina ; tubercles bai-e, shiny, each Avith a depi-essed dai'k seta ; 

 the anterior half of central furrow, a broad lateral stripe, and 

 the whole of presternum with dense large white scaling. Elytra 

 oblong, sides subparallel in S , slightly rounded in $ , shoulders
