convex, and the basal joint of the antennae is entirely rufous : the 

 females are readily distinguished ; lateralis by having angulated ma- 

 culae on the abdomen, whilst those on ochrostoma are round. The 

 male is widely distinct from that of ruficornis.

This species has not to my knowledge yet been discovered in 

 England. 



Sp. 15. pallescens, Schaffer, Germ. Zeits. vol. i. pt. 2. 281. 15. 

 This species is unknown to me. 



Sp. 16. alboguttata, Schaffer, Germ. Zeits. vol. i. pt. 2. 282. 16. 



I have frequently seen examples of this species from the conti- 

 nent, but it has not been found in England. 



Sp. 17. modesta, Schaffer, Germ. Zeits. vol. i. pt. 2. 282. 16. 

 This species is unknown to me. 



Sp. 18. flava, Schaffer, Panzer, Fab., Nylander, Kirby, &c. 

 This is the true male of ruficornis.

 Nomada neglecta, Schaffer (male). 



Some years ago I captured this species for the first time in En- 

 gland ; altogether I have not seen more than a dozen examples cap- 

 tured in this country : it is an autumnal species. The JV. neglecta 

 of Schaffer is I think the male.

I doubt very much if Schaffer was acquainted with the male of 

 this species, since he says it varies in having the spots on the collar 

 and scutellum obsolete. Although I have seen great numbers, and 

 once met with the species in profusion, I never saw the spot either 

 obsolete or partially so ; it is even more constant than in the opposite 

 sex.
