ON LIGHTNING BUGS

Since the publication of my synopsis of Lampyridae in 1851 (Proc. Acad. Nat. Sc. Phila, 1851, 331), but few species of the family have been described in this country, and no very important improvement has been made in their classification ; about the same time I published in the Journal of the same Society (New Ser., i., 73) a synopsis of Lycidae, one of the sub-families of Lampyridae.
