at tlie base, its area not defined ; extreme apex of femora, 

 base, apex, and outer margin of tibiaj and the tarsi pale. 



$ differs from cij/indricus in tbo ill-defined basal area 

 of tbe propodeum and its less rugose sides, its apex 

 truncate or slightly raised at the sides, but not sharply 

 angulated as in cylindricus ; the first abdominal segment 

 is wider at the base, exceedingly finely punctured all over, 

 and the entire abdomen is more densely hairy. 



L. 7-9 mm. 



Apparently rare. Chobham ; I had a colony in a path in 

 a garden under observation for some days. The females 

 flew about till nearly 3.30 p.m., and then began throwing

H. longulus, Smith. — So like the preceding that it 

 might be easily taken for a small form of it ; besides its 

 smaller form, the propodeum, looked at from in front, is not 

 distinctly margined and truncate on the brow, which is 

 narrower and the baseless rugose ; the basal segment of the 

 abdomen is rather more shiuiug, the puncturation sparser. 



The (? which I refer to this species is smaller than that 

 of malachurus, with its anteuna3, mandibles, &c., coloured 

 as in that species ; the propodeum more rugose, somewhat 

 truncate, its area indefinitely limited ; basal segment of 

 the abdomen less finely and closely punctured ; the apex 

 of the femora, the base, and sometimes the apex of the 

 ^ tibiae and the tarsi yellow. 



L. 6-7 mm.

This seems to me to bear to malachurus much the same 

 relationship that ulhijies does to cylindncus. 



H, pauxillus, Schenck. — S only differs from the pre- 

 ceding in its rounder face, rather shorter antenna?, less 

 rugose propodeum, almost inipuuctate first abdominal
