NOTES ON THE ENTOMOLOGY OP OXSHOTT. 26l 



of the attendants, who happened to see rae boxing them, 

 volunteered the information, " Oh ! do you want them things ? 

 There's plent}' of them up here every night ; great big 'uns, too, 

 sometimes "; but unfortunately I could elicit no further informa- 

 tion that would give me any clue as to what manner of moths the 

 *' big 'uns" might be. This lighthouse is, I believe, modelled on 

 the same lines, as regards external appearance and size, as the 

 original, which now stands upon the Eddy stone Rocks, and the 

 light is of similar brilliancy; if that be so, the light is some 

 hundred and thirty feet from the ground, and its capacity many 

 times greater than the numerous lamps around it, which after my 

 descent were as little frequented as they were earlier in the 

 evening. 



In a note on "Captures at the Electric Light" {ante, 248), 

 Mr. T. E. Sansom points out that at Yokohama the powerful 

 exposed lamps are very attractive to Lepidoptera, whereas the 

 smaller lamps, although situated more directly in the position 

 where the moths would be likely to fly about, seem to have no 

 particular attraction for them. At a meeting of the Entomo- 

 logical Society of London, Canon Fowler mentioned that moths 

 were attracted by an electric light fixed upon Lincoln Cathedral 

 during the Jubilee illuminations, Acronycta alni and Leiocampa 

 dictcea, which he exhibited, being among their number. 



It will be noted that in two of the cases mentioned a com- 

 parison may be drawn between lights of greater and lesser 

 brilliancy, and in each the more powerful lights drew many moths 

 to them, whereas those of less power had little, if any, attraction 

 for them; and in two also the lights were at a considerable 

 elevation, but their height proved no obstacle to their attractive- 

 ness. The inference therefore appears to be that a light of high 

 power placed in an exposed position is likely to draw the largest 

 number of moths to it, even attracting them from less powerful 

 lamps in its vicinity, a,nd it would be interesting to note whether 

 this rule holds good in all cases where a comparison between 

 two or more lights, or sets of lights, of unequal power and 

 position is practicable.

 By T. R. Bn^LUPS, F.E.S. 



Among the unidentified species of Hymenoptera-Aculeata, 

 &c., referred to by me, ante, p. 202, were Priocnemis hyalinatus, 

 Fab. ; Pompilus spissus, Scliiodte (this species was very plentiful) ; 

 Trypoxylon clavicerum, St. Farg., Crahro palmarius, Schreb., 

 several males of which were taken ; and Andreua fusclpes, Kirby. 

 The latter was common on Erica, &c.
