In this genus, of which Fabricius has described 

 only fifteen species, are included insects which 

 belong to the third and fifth families of my genus 

 Melitta, and to the second and fourth of Apis, all 

 differing as to their Instrumenta ciharia, Besides 

 these, others belong to a family of which we have 

 no species in England; whose proboscis I have not 

 had an opportunity of examining (/); and Nomada 

 punctata is either a variety of Fe5/j« uniglumis, Lin. 

 or nearly related to it. His description agrees 

 exactly with my specimens of that insect, which is 

 well figured by Panzer (m), only the four posterior 

 tibias are coloured black, instead of dusky ferru- 

 ginous. Thus Nomada gibha belongs to the third 

 family of Melitta, N. cingulata to the fifth [n) ; 

 N.ryficornis, niflpes, striata, Fabriciana, and Julvi- 

 cornis to my second family of Apis ; N. variegata 

 to my fourth. N. His trio and scutellaris seem 

 connected with Apis punctata, but in these the
