THE ENTOMOLOGIST. 115 



notes the breeding of Euchelia Jacobeae with three wings 

 only, the missing limb being the right under wing ; he adds 

 that it is not an uncommon occurrence among the Gometrae, 

 but not recorded in the Bombyces. The very day the 

 number of the 'Entomologist' reached me I bred a D. vinula 

 which looked a very good specimen, but on proceeding to 

 set it I found no trace of a right under wing ; I therefore 

 left the insect till shaped ; and if the Rev. J. Greene should 

 wish to possess it I can only say that I shall have great 

 pleasure in sending it to him. — S. Radcliff Fetherstonhaugh ;

Dysthymia luctuosa near Stroud. — In a field about a mile 

 from Stroud I have caught three specimens of Dysthymia 

 luctuosa: they seem to be very local, as I only caught them 

 in one corner of the field. — M. G. Musgrave ; George Street^

American Moth-trap. — In reply to S. T. C. (Entom. v. 

 61), when the late Mr. Hopley was here, on his intended 

 visit to the Isle of Man, he gave me a glowing account of a 

 wonderful apparatus he had brought with him to secure new 

 species, &c., but it was not unpacked until we reached the 

 island, else I am sure, from its self-evident optical mis- 

 management, we should never have taken it there at all, for 

 on seeing it I pointed out that, however large the light 

 within it might be, the rays therefrom were effectually locked 

 inside by the angles of the glass in front being so near the 

 angle of the light-rays ; hence little light could be distributed, 

 except from the small aperture by which the moths were 

 expected to enter the trap. However, having the evil with 

 us, and Mr. Hopley pressing so hard that it should have a 

 fair trial, we had the machine conveyed to Onchan Bay. 

 The night was an admirable one for lamp work, — dark, warm 

 and drizzly, — such as, with a properly constructed moth- 

 trap, I had repeatedly had great success upon ; and in con- 

 sequence of my successful practice on the coast with 

 lanthorns, Mr. Hopley pressed me to undertake the manipu- 

 lation of the " moth-trap." 1 confess I entered reluctantly 

 upon my task, feeling convinced I should lose a night's 

 work ; yet, hoping against hope, I placed the trap against a 

 rock-face on a raised ledge, and waited for darkness to 

 become visible by the light of the lanthorn, like " patience
