 were full-grown ; they also preferred spinning them- 

 selves up in moss or in dock leaves to entering the 

 earth. 



The perfect insects, and they really were very per- 

 fect and fine, forty-five in number, appeared at inter- 

 vals between June 4th and July 11th. (W. B.,

Plate LXXVIII, fig. 1. 



The larva was figured March 2nd, 1874. 



Towards the end of September, 1873, I received a 

 young larva of this species, no more than four- sixteenths
