Mr. Aldridge exhibited specimens of Deilephila Galii and D. lineata cap- 
tured by himself at Weston-super-Mare, 
Mr. J. B. Butler exhibited a number of rare British Lepidoptera, 
amongst which were 
Leucania vitellina 
Mr. A. E. Hudd exhibited fine specimens of Polyommatus Acis captured by 
himself in June 1871 in Wales. This exhibition caused some interest, as 
for many years this butterfly had not been observed in the United King- 
dom and was supposed to have become extinct. He also exhibited a species 
of Bruchus, supposed to be B. pectinicornis, bred from imported beans — a 
large proportion of the beans imported having been destroyed by this 
beetle. Some of the beans brought by Mr. Hudd when opened were found 
to contain from three to six beetles each. 
Mr. Barton brought for exhibition some of the Mexican walking seeds, (so 
called from their having the power of moving along,) and much amusement 
was caused by the eccentric movements of the seeds. If held to the ear a 
regular ticking sound similar to that caused by the death-watch beetle 
could be heard. Each seed appeared to have one or more beetles inside, 
but though carefully watched, the mode by which they were enabled to 
move the seeds along could not be discovered. 
The Hon. Secretary then read a short paper, being a contribution 
towards the life-history of Acidalia degeneraria, illustrated by specimens 
of the imago and larva, the parent moth having been captured July 18th, 
in the Isle of Portland, the only British locality for this species. The larva 
was previously unknown. 
Lythria purpuraria 
Polio nigrocincta. 
Sesia asiliformis and 
Cucullia Gnaphalii.
