938 MR. G. A. K. MARSHALL ON [DeC. 11, 



base to beyond middle and sharply constricted at apex ; upper 

 surface slightly convex, rugosely punctured, and with a deep 

 complete central furrow. Elytra only slightly sinuate at base, 

 broadest at the humeral angles, which are rather sharply promi- 

 nent, the sides subparallel from there to behind middle ; upper 

 surface slightly convex, with broad striae containing rows of deep 

 closely set punctures which are shallowly visible through the 

 scaling ; the intervals narrow, costate, the alternate ones distinctly 

 more elevated, the fifth with a small prominence on the declivity. 

 Legs piceous brown, the tibiae with a row of long erect setae on the 

 interior edge ; tarsi with the three basal joints subequal in length 

 and breadth. 



Cape Colony : TJitenhage {Father O'Neil). 



Type in the British Museum. 



This species has the appearance of a large B. coenosiis Gyl., from 

 Avhich it differs in its much shorter, thicker, and more sharply 

 deflected rostrum ; the scape and scrobe are also much shorter ; 

 the apical constriction of the thorax is stronger and the central 

 furrow deeper ; finally, in coenosus the punctuation of the striae 

 on the elytra is much finer and invisible through the scaling, the 

 alternate intervals are not raised, and the tibias have no long 

 setae. 



Bagous senegalensis (Faust, i. 1.), sp. nov. 



Long. 5i, lat. 2^ mm. 



Black, with uniform dense brown scaling. 



Read convex ; forehead with a large central fovea and without 

 supraocular prominences. Rostrum about as long as prothorax, 

 reo-ularly curved, and slightly dilated at apex ; upper surface 

 convex, smooth, the punctuation hidden by the scaling, the lateral 

 sulcus above the scrobe shallow and rather indistinct. Antennce 

 inserted nearer the apex of the rostrum. Prothorax as long as 

 broad, bisinuate at base, apical margin subarcuate dorsally, sides 

 subparallel from base to near apex and there sharply constricted ; 

 upper surface slightly convex, closely and distinctly punctured, 

 withoiit any central furrow, but with a number of irregular 

 shallow impressions. Elytra subquadrate, faintly trisinuate at 

 base, the humeral angles bluntly prominent ; upper surface almost 

 plane, with a broad shallow V-shaped impression near base and 

 with fine strias containing shallow punctures which are quite 

 hidden by the scaling, the intervals being broad, plane, and closely 

 punctured (beneath the scaling) ; intervals 3 and 5 each with a 

 large rounded tubercle at the summit of the declivity. Legs with 

 dense brown scaling ; tibiae denticulate internally, each denticle 

 with a short erect seta ; tarsi with joint 3 not bilobate, joint 1 

 longer than 2 or 3.
