Of this large and conspicuous species there are examples of 

 both sexes in the British Museum, one of which was formerly 

 in the collection of Mr. James Francis Stephens, who no doubt 

 obtained it from Dr. Leach, who first captured the insect in 

 Devonshire. Mr. Samuel Stevens captured a male some four or 

 five years ago in Devonshire, and Mr. Dossetor several of both 

 sexes last year in Wales.
