Blapsium
Blapsium is an extinct genus of beetles from the Middle Jurassic of England. The only described species is B. egertoni, which was first described by John O. Westwood in 1854. The species is known from a single specimen found by the William [Cole, 3rd Earl of Enniskillen|Earl of Enniskillen] in the Stonesfield Slate, now known as part of the Taynton Limestone Formation, which Sir [Philip Grey Egerton, 10th Baronet|Sir Philip Egerton] then passed to Westwood for description. The specimen is deposited in the Natural [History Museum, London]. It is incompletely preserved, lacking a head, pronotum and legs. It has a broad, convex body. It has a very short metathorax, which suggests that it was possibly apterous.
In his original description of the genus, Westwood compared Blapsium to the darkling beetles and ground beetles. Ponomarenko redescribed the holotype of B. egertoni and referred it to the tribe Notocupedini in the family Ommatidae, which was followed by Kirejtshuk.
