DESCRIPTIVE NOTES 



The following Hymenoptera appear new to me in the French 

 fauna. I append their description : — 



Cerceris antoniae, H. Fab. 



Length — 16-18 millimetres. Black, closely and strongly 

 punctured ; clypeus raised like a nose, i.e. forming a convex 

 projection, large at the base, pointed at the end — like half a cone 

 cut down its length ; crest between the antennas projecting ; 

 a line above crest, cheeks, and a large dot behind each eye, 

 yellow ; hood — yellow with black point ; mandibles, rusty 

 yellow ; tips, black. The 4th and 5th joints of antennae, rusty 

 yellow, the rest brown. Two dots on prothorax, wing scales and 

 postscutellum, yellow ; first segment of abdomen with two dot- 

 like spots ; four next on posterior edge having a yellow band 

 sharply hollowed in triangle form, or even broken, and this the 

 more as the segment is a less distant one. 



Under part of the body, black ; feet entirely of rusty yellow 

 colour ; wings slightly bronzed at tip. Female. Male un- 

 known to me. 



In colouring this species approaches Cerceris labiata, from 

 which, however, it differs remarkably in the form of the clypeus 

 and the much larger size of the insect. Observed round 

 Avignon in July. I dedicate this species to my daughter 

 Antonia, whose help has often been valuable to me in my 

 entomological researches. 



Cerceris julii, H. Fab. 



Length — 7-9 millimetres. Black, closely and strongly 

 punctured ; clypeus flat ; face covered with a fine silvery pubes-
