Erinnys Hicks, 1872: 177 . — Type species: Erinnys venulosa Hicks, 1872 , by monotypy ( Hicks 1872 ). Salteria – Walcott 1884: 31 . Menevia – Lake 1938: 270-272 . DIAGNOSIS. — Body elongate; micropygous; cephalon semicircular, wide and convex; fixigena meet in front of glabella; eye ridges at anterior third of glabella, tapering away; pair of librigenal spines; thorax of 25 segments or more with narrowing axis; pygidium small, axis tapering (based on Harrington et al. 1959 , with modifications). REMARKS Hicks (1872) first described Erinnys venulosa . The name Erinnys was occupied by Schrank & Schrank (1801) who named a genus of butterflies Erynnis . Walcott (1884) recognized the circumstances and renamed the genus Salteria in honour of Salter. However, Salteria was already in use for another trilobite described by Thomson (1864) , which was mentioned by Lake (1938) . Lake (1938) gave the name Menevia to the genus, but this name was preoccupied by Schaus (1928) . Stubblefield (1951) introduced Meneviella as a new generic name, which is still recognized today.
