segment; all the segments divided by very narrow 

 black bands ; a broad velvety black transverse band 

 across the middle of the back of each segment, on 

 which are placed four orange tubercles in the usual 

 order, the anterior pair being much the longest, ex- 

 cepting on the third and fourth segments, where they 

 are of equal size and placed in a transverse row ; all 

 the tubercles are furnished with bright golden-yellow 

 silky hairs, which give the larva a very beautiful 

 appearance. The spiracles white, ringed with black. 

 The sides of the body slightly garnished with hairs of 

 a pale drab colour. (W. B., 1, 67; E.M.M. Ill, 261,

ACRONYCTA MYRIOE. 



Plate LVII, fig. 6. 



I am indebted to the kindness of Mr. George H. 

 Kenrick, of Inverhadden, for the opportunity of offer- 

 ing a description of the full-grown larva of this 

 species, which I have proved by breeding the moth (as 

 far as I know) for the first time. 



The larva, taken in Perthshire, reached me 12th 

 September, 1869 ; it ate, apparently without prefer-

 in a tough silken cocoon covered with moss on the 

 15th, and the moth — a female — appeared on June 28th, 

 1870. 



I may mention that a Morayshire example of this 

 larva, sent me for example about the same time by 

 Mr. Longstaff, showed a decided partiality for birch. 



The Perthshire larva I figured on September 12th, 

 and at the same time noted the following particulars. 



The larva was one inch and a half in length, mode- 

 rately stout, the last three segments seen to taper a 

 little to the anal extremity when looked at from above ; 

 the head rather flattened in front, widest at the sides 

 just above the mouth, and scarcely less than the second
