THE ENTOMOLOGIST. 273 



Mr. Yeend Duer, of Cleygate House, Esher, an Annual Sub- 

 scriber. 



'J'he Chairman announced that the Council had again 

 resolved to offer two prizes, of five guineas each, for Essays, 

 of suflBcient merit and drawn up from personal observation, 

 on the anatomy, economy or habits of any insect or gi'oup of 

 insects especially serviceable or obnoxious to manl<ind. The 

 Essays must be sent to the Secretary at No. 12, Bedford Row, 

 on or before the 30th of November, 1867, when they will be 

 referred to a Committee to decide upon their merits ; each 

 must be indorsed with a motto, and be accompanied by a 

 sealed letter indorsed with the same motto and inclosing the 

 name and address of the Author. 



Mr. Bond exhibited four specimens, two males and two 

 females, of a Bombyx bred by Mr. Robert Mitford from larvae 

 found on the coast of Kent : he regarded them as merely a 

 variety of Bombyx Trifolii, differing from the normal form in 

 colour and in the antenna) of the male, though he was 

 informed that the larvae also differed and were of a golden 

 colour. The insect might be supposed to bear the same 

 relationship to B. Trifolii that B. Callunse bears to B. Quer- 

 cus, and had very much the appearance to be expected in a 

 hybrid between B. Trifolii and Odonestis potatoria. Other 

 bred specimens of B. Trifolii, from Cumberland, Hants, Dor- 

 setshire and Devonshire, were produced for comparison. 



Mr. Bond also exhibited several Fritillaries with unequally 

 developed wings ; and a remarkable variety of Dianthcecia 

 capsincola from York. 



Mr. Bond offered an explanation of the curious habit of 

 Macroglossa Stellatarum frequenting stone walls, &c., as to 

 which an inquiry was made at the previous Meeting. The 

 object was to secrete itself in some hole or crevice : he had 

 often noticed that the insect had a morning and an afternoon 

 flight, but in the middle of the day grew tired, when it would 

 seek out a wall or bank and creep up it until it found a hole 

 or cranny wherein to rest. 



Dr. Wallace corroborated this : when residing in the Isle 

 of Wight he had observed the humming-bird hawk-moth 

 resting in crevices of mud banks, &c., and on one occasion 

 he had captured in a limpet-shell a specimen which was thus 

 reposing.
