 (H P. Thomasset). 



Probably the name eriophora Klug should be used for this wide-ranging African 

 species, but as I am not certain I prefer to retain Sichel's name. 



3. Scolia (Dielis) pilosella Sauss. 



Mis pilose lla Sauss., Grandidier : Hist. Madagascar xx. p. 220, 1892.

There is a tubercle just in front of the intermediate coxae, as in the Eastern genus 

 Macromeris. The tibiae however in Macromeris are smooth, which is not the case in the 

 present species. The tubercle is also present, though less developed in M. hova Sauss. 

 from Madagascar, but is absent in combusta Sm. and other allied species from the mainland 

 of Africa.
