The M. unifasciata of Nylander is certainly not the unifasciata 

 of Smith's Essay, nor have we seen it in any British collection ; 

 all the English examples have the antennae pale red, and the 

 fascia on the abdomen extends to, or frequently beyond, the 

 second segment. Latreille may have confounded the two species, 

 but he has not mentioned the dark club of the antennae, a 

 conspicuous character ; the width of the band on the abdomen 

 varies in different specimens, so that it would rather appear that 

 Latreille was describing Schenck's insect, M. cingulata ; but we 

 think it best to adopt the nomenclature of Nylander and others.
