to account for the introduction of F. auricularia into this estate in any other way than through the agency of imported plants. Their prodigious increase can also be explained with no less diffi- culty, for refuse or anything which one might expect to be favor- able food is not permitted to accumulate. Not having the time to devote to the subject, I was unable to determine upon what the earwigs were feeding.
It seems quite important that the matter be investigated by economic entomologists, otherwise, F. auricularia might soon rival the familiar and unwelcome Blattella germanica as a house- hold pest.

This interesting fly was taken on one of my many collecting trips to the Berkshire Hills in western Massachusetts. I have delayed recording it, hoping that additional material would be obtained. <In the table of genera this would go in the genus Za- brachia Coquillett, but the form of the antennae would at once exclude it from that genus, while both venation and antennae bar it from the other genera of the group. Although lacking the anterior branch of the third vein, the position of the second and third veins is nearer that of Pachygaster than of Zabrachia. Berkshiria gen. nov.
Third joint of the antennae oblong, about double the length of the first and second taken together; third joint with five annuli, the basal one broader than the others; arista terminal, style-like, about as long as the entire antenna; front with two longitudinal ridges; transverse suture deeply impressed; scutellum large, rounded, with a broad depressed margin; third longitudinal vein without the anterior branch; ends of the terminal joints of the tarsi with bristle-like hairs. Type B. albistylum sp. nov.
Berkshiria albistylum sp. nov.
Black; front shining, the two ridges forming deep central and orbital grooves, ocelligerous tubercle prominent; face receding, the orbits white; antenna yellow, arista white with its basal fourth black. Thorax sparsely covered with a whitish pubescence; humeri angulate with a small yellow spot at each point, a raised collar extending between the humeri, and a blunt spine on each side before the base of the
