Knoch's name micanti is pre-occupied. My excellent and in- 

 genious friend Mr. John V. Melsheinier, makes the following re- 

 marks on this insect in a letter to me : " This insect is very nearly 

 related to M. sericea, but it is still sufficiently distinct, to entitle 

 it to the rank of a peculiar species. It abounds in hilly and 

 mountainous situations, where, in the month of May, the time of 

 the sexual union of the species, it may be seen flying about 

 amongst the whortle-berry bushes, in such profusion, that in a 

 very short time any number desired might be collected : whenever 

 a female alights upon the surface of the ground, she is immc- 

 <liately surrounded by a number of males."
