That I am able to offer a complete history of the 

 transformations of this species is another example of 

 the proverb, "Union is strength." 



For not to one only, but to several of my friends am 

 I indebted for help. To Dr. White and Mr. LongstafF 

 for the eggs, plentifully supplied to myself and Mr. 

 Hellins ; to Mrs. Hutchinson and to Miss Pasley for 

 sending me the surviving larvge reared by them over 

 the winter, when I had myself entirely lost all my stock. 

 As far as I can ascertain, only four larvae came to 

 maturity out of the two hundred hatched last year, the 

 vast majority dying in hibernation and at the first 

 spring moult ; it can well be understood, therefore, 

 how dear the satisfaction was, won after such loss, of 

 securing this species. 



The eggs were sent to us at the end of August, 

 1869 ; the larvse hatched during the first week of Sep- 

 tember ; fed and grew slowly till the winter ; hyber- 

 nated when between two and three lines in length ; 

 resumed feeding in March or April, and attained full 

 growth between the end of May and the middle of July. 

 The food was for the most part Aira prcecox, but 

 Mr. Hellins found that A. ccesjoitosa was eaten as 

 the larva approached maturity. One imago emerged 

 on July 15th. 



The egg may be called large for the size of the insect 

 and is nearly globular, though somewhat ovate, in 

 shape, and placed on end ; the shell is glistening, and
