the margins, are less distinct ; of the remaining two that near the 

 base is almost perfectly straight, while the anterior groove is very 

 strongly bisinuate ; disk somewhat uneven. Elytra with a grey 

 pubescence mottled with pale brown ; with some small granules 

 on the base and shoulders, from thence very sparsely punctulate ; 

 each with a small velvety black spot placed close to the margin 

 behind the shoulder. Body underneath and legs with a yellowish 

 grey pubescence. Antennae grey, with the third joint a little 

 shorter than the scape, the fourth barely longer than the third, the 

 fifth and following joints subequal. 



In the Museum collection there are two specimens — 

 one from Sierra Leone, the other from Old Calabar — 

 which agree in the relative length of the third joint of 

 the antennae and other structural characters with the 

 specimen just described, but differ by having two black 

 spots (placed obliquely) on each elytron instead of one. 

 Eor the present I regard these as forming a variety. 



The three following species form a separate section in 

 the genus Prosopocera characterised by having the horn 

 of the head in the male coming off from the base of the 

 front, and directed slightly upwards instead of down- 

 wards, and by having the two intermediate of the four 

 transverse grooves of the prothorax almost directly 

 transverse and parallel, instead of being more or less 

 strongly bisinuate. The prothorax itself is proportionately 

 somewhat shorter, with the pronotum less produced and 

 less rounded in front.
