NOTES ON COLLECTING.

possible for me to go into details here also; but I will take thia branch 

 of the subject as soon as possible, though luy notes on the genitalia of 

 the group are not so full as I naight have been able to make them, had 

 I felt able to finish the subject in the order I had origina% planned. —

Hearing ix Ants. — -It is still unknown to what extent ants can 

 hear. Forel has expressed the opinion that they are quite deaf. Lord 

 Avebury could never find that they seemed to hear any noises of a 

 variety of different kinds which he tested them with. He considered 

 it probable, however, that ants might produce sounds entirely beyond 

 our range of hearing. We know they possess stridulating''^ organs, 

 and some organs in the antennic and tibia' have been suggested as 

 hearing apparatus. Recently, through the kindness of my friend 

 Dr. Gordon Wilson, I have tested my ants in captivity with the whistle 

 known as the Galton-Edelmann. The human range runs up to 

 iO,000-50,000 vibrations per second, but tested by the sensitive Hame, 

 this whistle is seen to give ofi" musical notes far above that limit. 

 We tried my ants in every way with it, up to its highest range, before 

 which no sounds whatever could be heard by us, but the ants never 

 appeared to notice anything at all. — Horack Donisthorpe, F.E.S.,

r^^^OTES ON COLLECTING, Etc. 



Hybernatei) Lepidoptera on the Wing. — It may be worth notice 

 to say, I found two Scopelowvnt satelUtia at " sugar " last evening, 

 and to-day I saw a Goneiitenjx rhaiinii sporting in a sunny lane near 

 here. All through Novemljer and December N. mtelUtia was very 

 abundant. — H. G. Gregory. March 'did, 1910. 



Epunda lichenea and other species at Mull of Galloway 

 Lighthouse. — During 1909, Mr. Henderson, the keeper of the ^lull of 

 Galloway lighthouse, kindly sent me a considerable number of moths 

 which had been attracted by the light. Amongst a host of commonei- 

 species, I was very pleased to find a beautiful specimen of K}iunda 

 Urhenea (var. rin'iliriurta), and one of Litliasia ctHiiplana, as well as 

 I'rridroiiia n/isilnn (.s/(//'W.s«), /'. sdnria, Diaiithoecia ronspersa, and a 

 number of handsome specimens of IhisypoUa titnpU. Antlirocera fili- 

 lieitiliilan appears also to occur in that locality.- — Dorothy •). Jackson, 

 Swordale, Evanton, Ross-shiie. April 8th, 1910.

 the detection of four more specimens of IJt/ilroecia trinaneHiii!^, all c? s;

 this may be worth recording. — E. L. Strekt, Caithness House,
