BOTYS LANCEALIS. 129 



Of the three other full-grown larvaa before men- 

 tioned, it will suffice to say that their details were just 

 as I have already described ; the variations were simply 

 in the depth of the colouring; one was much darker 

 than the others, in which the light stripes of the back 

 were greenish-grey, the other parts proportionally 

 darker ; another was much paler, the stripes of the 

 back being ivory-white ; their habits also were similar. 

 Two of them reached the roseate stage on the 9th of 

 September, the third on the 12th. 



One spun its cocoon on the straight upper edge of 

 its cage, against the gauze top, to which it partly 

 adhered ; this was exteriorly much of a hammock 

 shape; this larva pupated on the 6th of May, 1875. 

 The two others chose to spin themselves up under two 

 or three leaves, which they securely fastened to the 

 side and bottom of their respective cages, hidden from 

 observation. 



The earliest moth to appear was a male on the 29th 

 of May from the first larva whose progress I have 

 traced ; from the second pupa a female emerged on 

 the 31st, and on the 7th of June a male ; the remaining 

 larva died from mildew attacking it and its leafy 

 hibernaculum. (William Buckler, 28th January, 1876 ; 

 E.M.M., May 1876, XII, 277—279.)

For this subject I have again to thank my friend 

 Mr. W. R. Jeffrey, who, some years ago, used to find 

 this larva near Saffron Walden on that local plant 

 Melampyrum cristatum ; and, while thinking it likely 

 that the more common species of cow-wheat might 

 also prove to be its food, he accordingly sought for it 

 in the summer of 1878 with complete success, taking 

 several of the larvaa, and most kindly sharing them 

 with me.
