 hips ; thighs of the hind-legs, all black ; those 

 of the two front pairs, black at the root and 

 yellow at the end. Legs and tarsi, yellow.

This Cerceris, the smallest in my district, 

 feeds her larvae on very small-sized Weevils, 

 Bruchus granarius and Apion gravidum. Ob- 

 served near Carpentras, where she builds her 

 nest in September, in the soft sandstone locally 

 known as sa/re.
