surface a uouud impression, third of about the same si/e and the 

 same shape, but with the external angle obtusely produced and the 

 upper surface nearly totally impressed, fourth irregularly ovate, inner 

 margin nearly straight, outer one rounded, sharply acuminate at tip, 

 entirely impressed on the upper surface ; antennae short and stout, 

 first joint cylindrical, not very long, second quadrate, both a little 

 broader than the following ones, third as long as broad, fourth little 

 transverse, fifth very large, longer than the three preceding ones 

 together, ovate, somewhat compressed inside, finely reticulated, 

 sixth small, very transverse, seventh about twice as large as the 

 sixth, transverse, eighth similar to sixth, ninth and tenth much 

 wider than seventh, lenticular, eleventh briefly ovate, truncate at 

 the base, obtuse at apex; prothorax longer and broader than the 

 head, rather abruptly constricted in front, two large and transverse 

 fovesB filled up with whitish glandular pubescence ; elytra long, 

 attenuated at the base, shoulders oblique and little marked, at the 

 base two strong foveas filled up with w^hitish glandular pubescence, 

 dorsal sulcus disappearing before the median part ; anterior troch- 

 anters a little swollen and the femora with a small and blunt inner 

 tubercle about the middle. Male. Length 2-50 mm. 



According to the shape of the palpi, which have no thin and long 

 appendages, this species should be included in the first group of the 

 genus, but it is very different from every other. Whilst in all the 

 other species of Psclaphocerus hitherto known the seventh joint of 

 the antennae is the largest of all, in P. nocUcornis it is the fifth one. 



Female unknown. 



Hab. Cape Colony (Uitenhage). 



Centkophthalmus brevispina, Eaffr. 

 (Vide supra, p. 408.) 

 The above description refers only to the female. Since then I 

 received the male of this insect, which does not seem to be very rare 

 at Uitenhage. 



Male : Antennal club much longer, joints eight to ten, ovate, longer 

 than broad, sub-equal, tenth however a little thicker at the apex, 

 eleventh much larger, ovate, rather elongate and obtusely acuminate 

 at apex.
