first news we heard of them was about two years ago, by a gentle- 
man who lives near Norwich, and they were supposed to be new- 
comers. This summer they have been much in High Suffolk — to 
the farmers’ and graziers’ great loss ; and we now hear they are 
likewise in some parts of Essex ; they are often discovered by hogs, 
who, as I am informed, are greedy of them at first, but having 
filled their bellies full, never care for them after.” Of these grubs 
Mr. Arderon gives the following information : — “They are a species of 
insect hut too common about Norwich, and to my own knowledge, 
have been more or less numerous in this county for twenty years past. 
They are the erucce of the scarabeus urbor c us, vulgaris major of Mr. 
Ray, that is, the tree or blind beetle, vulgarly, in Norfolk, called 
the dor. In different parts of England they are called the brown 
tree beetle, the blind beetle, the cockchafer, chafer (this is evidently 
only the Dutch and German word for beetle — kaefer), the jack 
homer, the jeffry cock, the May-bug, and the dor. In Cambridge- 
shire they are called Midsummer dors. Halliwell, in his specimens 
of provincial dialects, gives the following local names used in the 
Isle of Wight for this beetle : Straddlebob, and Dumbledore.” 
Arderon’s description of this beetle shews that he was not only an 
acute observer, but also able to describe clearly and accurately. 
“ This insect has two pairs of wings, one filmy and theother scaly. The 
first pair fold together under the latter, and remain quite hid unless 
when spread out for flight. The elytra or case wings are of a 
reddish light brown colour, and seemed sprinkled with a white 
powder that may be wiped off. The legs and pointed tail are 
whitish, the rest of the body brown, except at each joint on each 
side of the belly, where there is an indented line of white. The 
circles round the eyes are yellowish, and so are the antenna ?, which 
are short, and terminated by lamellated tufts, capable of being 
opened more or less.” 
Mr. Arderon then proceeds to give several instances of the 
destructiveness of the larval of this beetle in the year 174G. 
“ On a farm at Heathel, near seven miles s.w. of Norwich, of £80 
per annum, belonging to the St. Helen's hospital in this city, in the 
occupation of Mr. James Elden, these insects were so numerous last 
year that the farmer and his servants affirm they gathered 80 
bushels of them, the erucse of which had so spoiled the produce of 
his farm that the Court of this city, in compassion of the poor
