young buds, which are probably the food on which all these 
beetles subsist a/ter arriving to their perfect state. 
Other marks which characterise this insect may be gathered 
from the description which we present of the following species 
and the comparison between the two which is there instituted. 
The rough intervals between the elevated smooth black linos in 
this species are usually of a brilliant brassy yellow color, but 
varieties occur in which they are coppery red, black, brassy 
gray, or beautiful brassy green. In one specimen before me 
the two middle raised lines of the wing covers are confluent, 
separated only by punctures but with no depression between 
them. 
220. New-Yoiik Buprestis, Chalcophora Novaboracensis, new species. 
A beetle closely related to the preceding, but slightly larger, 
the males measuring 0.90 and the females one inch in length, 
with the raised lines of the wing covers much more broken and 
irregular, the third line small and commonly wholly obliterated 
except an elevated smooth spot on the outer side of the poste¬ 
rior impressed spot, which smooth spot is confluent with the 
outer raised line, this line being more slender than either of the 
other raised lines and much more slender than the correspond¬ 
ing line in the foregoing species. 
Only five individuals of this species have fallen under my 
notice, two of them males. Though' closely resembling the 
insect last described it is undoubtedly distinct; and a compari¬ 
son of these two species will give the reader a more distinct 
view of each than to describe them separately. 
In both these insects the front has an impressed line along its middle, but 
here this impression is mqre widened and is crossed on the middle of the face 
by a transverse indentation of the shape of a crescent with its convex side up¬ 
ward. The smooth elevated lines on each side of this middle line, which are 
more or less distinct in the foregoing species are not obvious here. The eleva¬ 
ted smooth line on the middle of the thorax is much more narrow here and 
often becomes narrower posteriorly, sometimes wholly vanishing before it 
reaches the base, whilst in the preceding it tends to widen posteriorly. The 
elevated smooth irregular stripe on each side of the middle, in which are a few 
punctures, and which is forked ns it were at its forward end, with the outer 
branch of the fork more broad, is here continued to the base of the thorax, 
whilst there it terminates, wholly or partially, before it reaches the base. 
The elevated smooth pyramidal spot on the base outside of this and opposite
