130 INSECTS INJURIOUS TO FOREST AND SHADE TREES. 
pale brown line, wider on the costa, and an outer line making a great bend in the mid- 
elle of the wings. Beyond the outer line the wing is brown, either reddish or umber 
lhrown, with dark cross specks, and two diffuse spots near the middle; one near the 
Ieead of the outer line and another near the tip of the wing. The hind wings are 
sinuous on the outer edge; the wings expand from aninch to an inch and a half. 
2. THE BEECH LEAF-MINER. 
Brachys wruginosa Gory. 
Order COLEOPTERA; family BUPRESTID®. 
Mining the leaves of the beech, a whitish flattened larva, changing to a small flat- 
tened hard-shelled beetle. 
Dr. Harris has given in his “ Treatise” an account of the larva of 
Hispa which mines the leaf of the apple tree, eating the pulpy 
substance between the upper and under surface of the leaf. 
The insect of which we now treat belongs to the family of 
Buprestids, several species of which, as we have seen, do 
much injury to our fruit and shade trees in the grub state. 
They are footless grubs and recognized by the broad, rounded, 
flattened segment just behind and partially enclosing the 
head. The young of Brachys, ete., depart somewhat from 
this typical form owing to their peculiar leaf-mining habits. 
The first of these is the young of the Brachys wruginosa, which 
has been found by V. T. Chambers, Esq., of Covington, Ky., 
eee mining the leaves of the beech tree, and I am indebted to 
beech leaf. him for a specimen of the larva here figured (Fig. 603).

enlarged — I may remark here that a closely allied beetle (B. termi-— 
rom acK- c . . : 
ard, nans) is often to be seen in Maine resting on the leaves of 
the oak and beech. The beetles of this genus are flattened, angular 
ovate, and less than a quarter of an inch in length, and the scutellum 
is small, as Leconte observes, while the shanks (tibice) are linear. In 
the succeeding genus, Metonius, Leconte says that the body is triangu- 
lar, while the scutellum is large, and the shanks are dilated. 
Larva.—The body of the larva is rather long, with the segments very deeply cut, be- 
ing flattened, and produced laterally into a triangular projection, giving a serrate out- 
liimwe to the body, the teeth being obtusely rounded. The segment next behind the 
lhead is the widest, the succeeding segments gradually decreasing in width and in- 
creasing slightly inlength to the end. The terminal segment is about half as wide as 
the body in its widest portion, andis somewhat triangular, with the sides parallel, 
cand the tip obtusely pointed. The prothoracic segment or the one next the head is 
broader than long, and has a fleshy projection on each side at the base of the head. 
On the upper side of this segment is a large, square, slightly horny area. The head 
is anteriorly pale honey yellow, with two dark longitudinal parallel lines; the horny 
portion is about as long as broad, much flattened, subtriangular. The antenne are 
wery minute, slender, three-jointed, with the joints nearly equal in length. The jaws 
and palpi are so minute that a description will be of no practical use here. The body 
is finely shagreened, with afew fine scattered hairs. Itis whitish, with a slight green- 
ish tinge, and a quarter (.25) of an inch long, and less than a tenth (.07) of an inch 
road. It was sent to me alive in September.
