Having arranged for a two months trip to Europe during the past summer, I determined to visit the Natural History Branch oi the British Musenm, to endeavour to clear up the doubt surrounding Walker's spilosoma Congrua, taking with me a number of specimens of S. Antigone, Strecker; a pair of the heavily-spotted Gomin form of Spilosoma, which Dr. Fyles calls Cunea, lent to me by Mr. Winn; a typical female specimen of S. Prima, kindly given to me by Mrs. Slosson; and a small series of Hyphantria Cunea, Drury. I reached London late on the 26th June, but on the morning of the 29th received a cablegram which necessitated my immediate return home. After making my arrangements to sail from Liverpool on the 30th, I found I had a few hours to spare, and so paid a very hurried visit to the Museum, and was shown what was supposed to be the three types of Congrua by sir George Hampson, who kindly remained after the closing hour to accommodate me.
