British Hymenoptera. 189 



angles of tlie truncature slightly produced ; 8th narrow and tongue- 

 like (for genitalia see PL VII., figs. 10 — 10 6). Legs ferruginous; 

 femora black. 



2 . Slightly larger, less pubescent, and with the central lobe of 

 the scutellum and the tubercles rufous. Abdomen generally with 

 the four spots distinct on the 2nd segment, as well as on the 

 following ; abdomen beneath black, somewhat shining ; 2nd seg- 

 ment largely and distinctly punctured; apical segment rather 

 narrowly rounded ; 3rd and 4th with a pubescent apical band. 

 Legs red ; posterior and intermediate femora black above. Length, 

 8—10 mm. 



Hah. Sandy places ; Norwich, Littlehampton, Hay- 

 ling Island, and probably in many other places, but con- 

 fused with the following under the old name variegatus. 



2. Epeolus rufipes, Thorns. (PI. VII., figs. 9 — 9 a).

Extremely like the preceding, but differs in the follow- 

 ing characters, which I think are certainly of specific 

 value : — 



The labrixm has its apical margin simple, not tridentate, and the 

 two teeth on the disk situated considerably below the middle ; the 

 spots on the 3rd and following segments of the abdomen are more 

 transverse, and tend more to form bands ; the apical dorsal valve 

 of the (J is not parallel-sided as in productus, but is slightly nar- 

 rowed towards the apex ; beneath, the abdomen is dull and often 

 rufescent, and the 2nd segment is closely and finely punctured ; 

 the apical segment of the $ is very largely and widely rounded, 

 and the legs in that sex entirely red. Length, 5 — 8 mm. 



Hah. Deal; Falmouth. 



The confusion of the two species makes it impossible 

 to quote localities, except where the actual specimens 

 have been seen.

Labial palpi 4-jointed, maxillary palpi 5-jointed ; 1st joint of the 

 former much more than twice the length of the 2nd ; wings with 

 three submarginal cells ; ^ with six ventral segments exposed ; the 

 7th somewhat bifurcate at the apex ; the 8th subtriangular, with a 

 few apical setae ; armature stout ; cardo small. 



A genus of parasitic bees found with Anthophora.
