PINK. TRUNK. 
groove along its middle, the second broadest and tawny on its 
forward corners, the third and fourth rings short, together only 
equaling the fifth and following rings which are of equal length, 
and have an oval flat transverse elevation above and two ele¬ 
vated folds of the skin on each side, and with six small white 
feet anteriorly on the under side. 
This common species has received a number of names from 
different authors, Foster having bestowed upon it that of 
brunneus in 1771, Drury unicolor in 1773, Fabricius cylindricus 
inT781, Gmelin cylindroides in 1788, and Olivier sulcatus in 1795. 
Though I have not at hand the date of the volume in which De 
Geer’s name was published, I suppose it to have preceded all 
the others.

rambycidse. 
A beetle closely resembling the preceding, but with much 
shorter antennae^ only one tooth on each side of the thorax, and 
several raised lines on the wing covers. 
This rare insect, which has only been found hitherto in New

it to be bred in the pine, having in one instance met with the 
beetle, dead, under the loose bark of one of these trees. 
241. Ribbed RnAGirar, Rhagium lineatum, Olivier. (Coleoptera. Lepturidie.) 
Common in the pitch pine, several often in the trunk of the 
samo tree, excavating a broad irregular patch in the outer sur¬ 
face of the sap wood, the cavity being mostly filled with saw¬ 
dust; a yellowish-white grub about an inch long, divided into 
segments of nearly equal length and width, except the second 
which is the broadest, and the last which is narrowest with its 
end rounded; surrounding itself with a broad oval ring of 
woody fibres, like short threads, placed between the bark and 
the wood, in which to pass its pupa state; changing to a beetle 
which lies in the same cell through the winter and comes abroad 
in the spring; the beetle 0.40 to 0.70 long, long and narrowish, 
its head and thorax much narrower than the wing covers, cyl- 
indric, clothed with soft gray hairs upon a black ground, the 
thorax with a black stripe above and one on each side, where is
