This rare anisopodid fly had been taken hitherto only in NewYork, Pennsylvanlaand northern Virginia. The writer-captured
a single female specimen on the eastern slopeSof Mt. T9by,Franlilin Co., Massachusetts,M.ay 17, 1924. Down this slope
mossof Toby a large mountain stream pours over den-sely^
covered bouldeis, reaching the lower levels near the Central
Vermont Railroad siding near Montague. The specimen ofAxymyia was swept from vegetation along this stream, -at -alaltitude of approximately 600 feet, where it was associatedwith
various Tipirlidae, notably small swarms of Ormosia nubila(O. S.) and Ormosia meigenii (O. S.) and numerous scatteredindividuals of. Tricgphona uernalis (O. S.) and' Tipula iroquo'isAlexander. When at rest in the net, the fly resemblesa small
leptid or a speciesof Anisopus, Like the speciesof Tipylidae
with which it was associated,this fly is presumably a member ofthe vernal Dipterous fauna of the Canadian-Transition life-zone.

This crane-fly was described from a single-s-pecimen.taken

atKeene Valley, ilssex Co., New York, in late May. It has since
been found commonly at Amherst' Massachusetts,-whereit^flies
during the month of May. In 1923,the fly w&son the-win-gfrorn
