inserted at about the middle of the truncature, short, thick at the 

 base, rather abruptly aculeate at apex ; antennae stout, first joint sub- 

 cylindrical, second quadrate, both larger, third to sixth moniliform and 

 a little transverse, seventh not broader but quadrate, eighth to ninth 

 larger, tenth sub-quadrate, slightly increasing, eleventh large, briefly 

 ovate, truncate at the base, rounded at the apex ; prothorax a little 

 longer than broad, more attenuate in front than at the base, rounded 

 on the sides, lateral foveas small, median one larger; elytra with 

 the posterior margin darker, longer than broad, a little attenuate 

 towards the base with the shoulders oblique and little marked, two 

 foveas at base, the external one large and elongated in a broad but 

 short sulcus ; first dorsal segment of the abdomen short, entirely 

 bi-carinate, second more than twice as long as the first one ; the two 

 carinas are nearly complete ; metasternum convex, and with a fine 

 stria ; all the femora, more especially the anterior ones, thickened, 

 anterior tibiae much thickened in the middle, arcuate, intermediate 

 ones a little thickened towards the apex and a little curved, posterior 

 ones straight ; no sexual mark. Length 1'80 mm. 



This species, compared with the preceding one, differs at first sight 

 by the much shorter and much thicker antennae. In that respect it 

 resembles very much C. armatus, Eaffr., from Abyssinia, but in this 

 species the infra-ocular spine is long and sharp, and the two carinae 

 on the second dorsal segment do not extend as far as the middle of 

 the disk, whilst they are nearly entire in G. brevispina. Another 

 African species, C. villosulus, Fairm., from Algeria, has the infra- 

 ocular spine very small, but the joints of the antennal club are much 

 longer.

Eesembles much P. peringueiji, Ealfr., but the head is longer, 

 narrower, not at all attenuate in front, with the sides parallel; 

 the hairs are darker, being black, except on the posterior margin 

 of the elytra ; the palpi are very much alike, the last joint being,
