Compsilura concinnata Meigen, This is a medium-sized Dipterous parasite or two-winged flyof the family Tachinidae attacking both the gipsy and brown-tailmoths. It was colonized at Putnam in 1912, Hartford in 1913,Mansfield, Plainfield and Stonington in 1914, Stafford, Sufheld,Colchester, Norwich and Old Lyme in 1915, and Hampton andScotland in 1917.

Sturmia {Zygobothria) nidicola Townsend. This is another Tachinid fly of medium size parasitizing thelarvae of both gipsy and brown-tail moths, and though nevercolonized in Connecticut, it was recovered from Canterbury andWaterford in 1917, and from Groton and Stonington in 1918. The foregoing records of parasites lead us to believe that mostof these species have become fairly well distributed around theinfested portion of the state even though not actually planted GIPSY MOTH WORK. 165 there. Some help may therefore be expected from them in theyears to come. The effectiveness of parasites depends much uponconditions, and is usually more pronounced in localities where thehost is extremely abundant, and on account of the suppres
