 Variation in Arctia mendica at Huddersfield. — At the meeting of the 

 Entomological Society of London, held July 3rd, 1SS9, Mr. G. T. Porritt exhibited 

 . remarkable series of Arctia mendica L. , bred from a small batch of eggs found 

 'ii the same ground at Grimescar, Huddersfield, as the batch from which the
