Extract

As I was working over a series of Nemestrinid flies with Curran's key, certain variations at once became apparent. The series consists of 93 females of Rhyncocephalus sackeni, Williston, identified by Mr. Curran himself, and it seemed advisable to list the points used in the key and to assign therein the irregularities occurring in the flies, together with some variations in wing venation.
