APLECTA HERBIDA. 89 



its change to a pupa was very gradual, but completed 

 by the 1st of February, 1876. Mrs. Hutchinson sent 

 me an example of some she had reared chiefly on straw- 

 berry leaves ; they were all in their last coats by the 17th 

 of February, 1876, and similar to mine above described. 



This last pupa lay in a hollow of the earth, covered 

 only by a leaf, and had the larval skin sticking to the 

 tail and beneath the abdomen. It is a little more 

 than three-quarters of an inch long by a quarter of an 

 inch thick at the widest part, decidedly a stout pupa. 

 The wing-covers rather short, otherwise much of the 

 ordinary form, very dark purplish-brown and shining. 



On the 19th of June a crippled male A. herbida 

 appeared from another fine pupa enclosed in a thin 

 and extremely brittle cocoon of earth, though smooth 

 inside yet with very little silk ; in this instance the 

 old larval skin also adhered to the tail of the pupa, 

 but when removed the tail was found to end with two 

 curled-topped spines a little diverging; the wing- 

 covers of ordinary length and development. (W. B., 

 June, 1876; N.B., III, 54.)

For a complete set of figures of the larva, and the 

 opportunity of studying the history of this species 

 from the egg, I have been indebted to many kind 

 friends, beginning with Dr. F. Buchanan White, who, 

 on October 6th, 1868, sent me four young larvse swept 

 from heather at Achilty, Ross-shire, which, though 

 put on a growing plant, died in the following 

 February. Next I received on May 1st, 1869, from 

 Mrs. Hutchinson, a full-grown larva brought safely 

 through the perils of hibernation, but which unfortu- 

 nately died soon after, while in the process of changing 

 to pupa In the same year, on the 18th of August, 

 Mr. Longstaff, then staying at Cluny Hill in Moray-
