The finding of Gryllus domesticus in great abvnudence in Baltimore, 
New York, and various other localities in the easter part of the United 
States has been reported, but no specimens have been received for the Na- 
tional Collection, we would like to have a long series of specimens of 
both sexes in adult and nymphal stages. It may be distinguished from the 
other species of Gryllus by its generally lighter color and by the two black 
bands across the foreheads 

T, He Colbrook Taylor, who for the last three years has been engaged 
by the British Government in the study and imnortation of parasites for the 
control of insects affecting the coconut palm in the Fiji Islands, recently 
spent a few hours of a short stay in Washington consulting with various 
specialists in the Museum regarding features of his work. He was on his way 
to his home in Mngland for a vacation. Mr, Taylor reported that the estab— 
lisnment in the Islands of a certain tachinid fly, as a parasite of a moth 
Which was threatening to destroy the copra industry, had proven a phenomenal 
success, the moth having been reduced to a point where it was no longer do- 
ing any damage.
