1898.] of the Coleoptera of South Africa. 411 



obsoletely divided ; between the eyes are two foveae more distant 

 from each other than from the edge ; three last joints of the palpi 

 triangular, narrowly and sharply produced outwardly in the shape 

 of a fine appendage, the last one a little transverse ; antennae rather 

 elongate, very different in both sexes ; prothorax larger than the 

 head, rather abruptly narrowed in front, dilated and rounded 

 before the middle, at the median part of the sides a very transverse 

 and sulciform fovea, clothed with whitish and glandular hairs ; 

 elytra attenuate at base with two foveae, and a short, wide dorsal 

 sulcus ; in the anterior legs the trochanters have a very long and 

 sharp spine and the femora a shorter, sharp spine ; metasternum 

 very little impressed. 



Male: First joint of antennae long, cylindrical, second to fifth very 

 nearly equal to each other, longer than broad, sixth the same width, 

 but more than half shorter, transverse, seventh very large, irregu- 

 larly trapezoidal, larger at the apex where the margin is sinuate and 

 obtusely dentate, eighth inserted at the inner angle of the preceding 

 one, similar to the sixth but smaller, ninth not broader, much less 

 transverse, tenth hardly longer than ninth, but three times broader, 

 very transverse and produced externally, eleventh large, irregularly 

 ovoid, the under part bearing a large, transverse, but not deep fovea ; 

 the spine of the trochanters is shorter, the one on the femora smaller 

 and slender, the shoulders more angulate and prominent. Length 

 2*60 mm. 



Female : Second, third, and fourth joints of antennae very 

 nearly equal to each other and a little longer than broad, fifth a 

 good deal longer, sixth sub-quadrate, a little transverse, seventh 

 longer and a little stouter than fifth, a little produced at the inner 

 apical angle, eighth very transverse, ninth and tenth larger, trans- 

 verse, eleventh oval ; shoulders much less prominent, but still not 

 entirely absent. Length 2*30 mm. 



This species is very interesting inasmuch that by the con- 

 formation of the palpi it belongs to the second group, and by 

 the antennae to the first group of the genus, being a transitory 

 form.
