Allied to P. rufipes Jeann. (of which I have a specimen 

 from the Gold Coast before me), from which it is at once di- 

 stinguished by smaller size, much shorter first antennal joint, 

 non-tuberculate före lobe of pronotum, unarmed pronotal 

 lateral angles, much reduced lateral spines to scuteilum, dif- 

 ferent colour of connexivum and legs, much shorter pilosity 

 on pronotum, scuteilum, abdominal margin and legs, and the 

 thick puncturation and pilosity of the ventral base and apex.

The specimen is of the size indicated by Jeannel. Of 

 this species I have also seen several specimens fromNyasaland; 

 these are all of smaller size. 



On Ä. Felixi and two alHed species Jeannel founded the 

 subgenus Leptacanthci-spis , which differs from most species 

 of Acanthaspis s. str. by the narrow oblong body, the some- 

 what longer head, the less developed and less protuberant 

 eyes (which cannot, however, be called »tres petits»), and 

 the short basal joint of the hind tarsi, Avhich is only 

 half the length of the second joint. To these characters, 

 given by Jeannel, can be added that the four anterior 

 femora beneath are densely but very minutely and more or 

 less distinctly denticulated or serrulated or a b least finely 

 granulated, and that the venter of the male is roof-shaped 

 and carinated in the middle from its base to the apex of the 

 fifth segment. Jeannel says that it also differs by having the
