This species is distinct from B. vasuta owing to the longitudinal 

 sulcus of the prothorax, which is hardly visible, the much shorter 

 olytra and the shape of the head, especially in the male. 



Hal). Cape Colony (Constantia, Newlands). 



Eaffrayia sulcatula. 



Oblong, somewhat convex, ferruginous, rufous or testaceous,. 

 covered with a pale pubescence, legs and last joints of the antennae 

 lighter in colour ; head large, shorter than broad, sides rounded, 

 attenuate in front, foveae and sulci very deep, a somewhat geminate 

 and deep impression on the frontal part, and a long carina extend- 

 ing from the neck to the front ; eyes very small ; antennae rather 

 elongate and slender, first joint sub-cylindric, second sub-quadrate, 

 longer than broad, third quadrate, smaller than the following one,, 

 fourth, the largest, little transverse, fourth to ninth the same form 

 but slightly decreasing, tenth broader and moi'e transverse, eleventh 

 briefly ovate with the apex abruptly conical ; prothorax very cordate, 

 sides and anterior margin well rounded together, hardly broader than 

 the head, longitudinal sulcus very feeble but never totally wanting, 

 sides hardly sinuate posteriorly, the transverse sulcus strong, angular 

 in the middle, and the median groove of about the same size as the- 

 lateral ones ; close to the base are four small grooves ; elytra smooth, 

 much longer than broad, and very attenuate at base, no shoulders,, 

 dorsal sulcus valid, disappearing before the median part ; first dorsal 

 segment large, feebly impressed transversely at base. 



Male : Metasternum hardly impressed, intermediate trochanters 

 with a small tooth at their base, last ventral segment strongly 

 sinuate at the apex on the sides and projecting in the middle, hardly 

 impressed. 



Female : Metasternum convex, last ventral segment rounded at 

 apex. Length 1-70-1 '80 mm. 



This species is closely allied to B. nasuta and B. arviata ; the 

 male will be very easily distinguished because the inferior part of 

 the head has no scvilpture and the frontal part is not produced as in 

 nasuta. For the female the colour is the same as in B. nasuta and 

 much lighter than in B. armata, the antennae are much more slender 

 than in both these species, the intermediate joints being hardly 

 transverse ; the size is larger.
