16 CORN AND GRASS. 



about half the width of the cocoon, and one-sixteenth of an inch less in 

 length, and, as far as I saw, lay with the tail extremity either fastened 

 to the inside of one end of the cocoon or quite close to it, the spare 

 space being at the head end. Some of the cocoons lay separately, but 

 for the most part they were spun into clusters by admixture of much 

 caterpillar-web, together with caterpillar-dirt, bits of stick, or leaf, or 

 flower of the material of the stack, and small rubbish generally. 



The first moth appeared (out of cocoons sent me) on or about June 

 7th, and other specimens appeared from small consignments of cocoons 

 sent me by Mr. Gardner for several weeks. These moths (the Pyralis 

 glaucinalis) are from a little under to a little over an inch in the 

 spread of the fore wings, which are shiny, and pale grey or grey brown, 

 somewhat browner towards the fore edge (the costn), which has a dis- 

 tinctly reddish tinge. Two yellowish lines or sle;ider bands cross the 

 wings transversely from back to front, so as to divide them into three 

 nearly equal portions ; and between the extremities of these, at the 

 fore edge of the wing, the reddish colour of the costa is very prettily 

 alternated with a few buff spots. The hind wings are also greyish, 

 with two pale cross lines ; and round the extremity of each of the four 

 wings, just inside the fringes, there is a faint line, sometimes scarcely 

 observable. 



On the 20th of July, that is, about six weeks after Mr. Gardner 

 forwarded me the first specimens, he wrote again concerning this stack 

 infestation : — " I enclose a few more of the odd-looking cases, which 

 appear to me to have some chrysalids in them, which I found around 

 a stack of second-cut Clover growth of 1891. The other stack is now 

 being cut out, and the old 'trusser' says he has seen them before, and 

 they do not go in far from the outside, and (although one hay-merchant 

 who saw them said they would eat the Saintfoin, and he would not 

 have the stack at any price), this old man, who has bought the stack, 

 has made no fuss about it." On the 28th July Mr. Gardner, sending 

 me at my request a further supply of the cocoons, wrote accom- 

 panying: — "I have to-day collected the enclosed, which I hope you 

 will find useful. I found them in every one of the stacks, excepting 

 this year's, and even in this year's I started a moth, but they seemed 

 to have preferred the Clover and Saintfoin, as there were very few in 

 the old haystack ; they seem to prefer it where it is looser ; I suppose 

 it is easier to get further in, and they were apparently more on the 

 N.E. and N.W. sides of the stack." 



A little later (on the 10th of August) Mr. Gardner wrote: — "I 

 have been to the stack two or three times since, and find the moths 

 are still coming out, but they do not seem nearly so numerous. They 

 frequent the upper part of the stack more than below I suppose 

 because they find penetration easier ; in the old haystack, which is very
