LiniHophila. Professors Mik* and Thalhammer^ also referred this 

 species to the genus Cladura, while Bergroth^ placed it in the genus 

 Uloniorpha. Kertesz in the Catalogus Dipterorum regards it as a 

 synonym of Adelphomyia senilis Haliday, which position it still holds. 

 Besides the recent species, Scudder' has described two fossil species 

 from the Florissant.
