tibia is not furnisbed with teeth beneath ; the hind femur is 

 flattened, broad in the middle and b-^ars a broad shining 

 laminar appendix at its lower edge ; the iiind tibia is strongly- 

 curved, serrate within and has also a small laminar inner 

 appendix at its extremity.

This is of similar size and appearance to Sisyphus goryi, 

 Har., and like it clothed with rusty coarse setae and earthy- 

 matter; indeed it is in all respects extremely like that species, 

 differing only in the rather longer legs, the elytra a little more 

 rounded at the sides and less tapered behind, the very sharp 

 inner clypeal teeth, and feebler outer ones. 



Tiie sexual difi'erences are slight in these and the small 

 species of Sisyphus ^Q.ntx\x\\y , and the synonymy of these still 

 remains in the greatest contusion. Mr. Peringuey considers 

 S. goryi, Har., to be identical with S. crispatus, Gory ; but 

 the first is described from West and the second from South 

 Africa, and as a species exists in Senegarabia to which the 

 description of S. goryi can be applied there seems no reason to 

 adopt Mr. P^ringuey'sview. The latter's species, S.nanniscus, 

 is the insect called S. rvgosus by Roth (a pre-occupied name) 

 and considered by Gemminger and Harold to be the S. ocel- 

 latus of Reiche. Tlie last appears to me to be another 

 species of which there are representatives in the British 

 Museum from Nyasaland and the interior of Angola. It is 

 peculiar in having denuded spots upon the pronotum, as 

 shown in Reiche's tigure. These names should accordingly 

 stand as follows : — 



crispatus, Gory. Abyssinia to Cape Colony.
