omerged as a handsome female in August, confirming the opinion 

 that there was an autumn as well as a spring brood. 



The question arose how did the caterpillars find their 

 way to the place where found 1 Had some enthupiast placed 

 them there ? Had a female escaped from captivity and laid 

 eggs 1 This idea was negatived by the fact that P. Machaon did 

 not breed in captivity ; or had an impregnated female crossed the 

 channel and deposited her eggs in Sussex 1 This idea was partly 

 confirmed by the fact that on the first of the month a swallow- 

 tail had been taken at Hastings. It was well known that P. 

 Machaon was found in considerable numbers in Norfolk and 

 Cambridgeshire, and on the Continent. It is reported that 

 this butterfly was formerly taken in Sussex in the Weald. He 

 quite expected to hear of other specimens being taken in 

 the county next spring. 



Mr. DowsETT exhibited a butterfly new to Britain, Thais 

 Mumim, found in the Brighton Market, probably imported in 

 the chrysalis from the Continent with fruit, flowers, or vegetables. 

 At the time of its capture the wings were not quite dry. This 

 species is found in France, from which country it had probably 

 been brought in the way named above.
