B. duplicatus was sent to me a.s j^ellucidus by tlie Rev. Theodore 

 Wood many years ago. He took it in great numbers in July, 1886, 

 between Broadstairs and Margate, lying about in hollows on the sand 

 (Ent. Mo. Mag., xxiii, 40). In a recent letter to me Mr. Wood says, 

 " They were restricted to one small patch of sand, just above high- 

 water mark, and were over in two or three days. I never found the 

 species again." In June, 1898, the same species was also sent to me 

 as jwllucidus, by Commander Walker, E.N., from the Blean Woods, 

 Kent, where he frequently took it trapped in water in deep cartwheel 

 tracks, as well as in faggots (Ent. Mo. Mag., xxiv, 208). The Eev. 

 H. S. Gorham records the capture of Omias peUucidus, at Eastry, near 

 Sandwich, in 1872, "in great niimbers crawling in the sandy gravel by 

 the side of the road. The dead bodies of hundreds, and thoracic and 

 femoral development of the males, testifying to the severity of the 

 struggle for existence " (Ent. Mo. Mag., ix, p. 118). I have not seen 

 any of these specimens, but the reference to " the thoracic and femoral
